Upgrade MCP for IaC page: landscape survey, security section, schema fix

[workprentice]

Summary

Upgrades content/what-is/mcp-for-infrastructure-as-code.md — the existing "MCP for IaC" page — to close five gaps against the target spec: no cross-vendor landscape survey, no original statistics, no security/governance section, a stale MCP spec version, and a schema bug that silently dropped Article + author Person schema.

The page already existed on master before this PR (authors: alex-leventer, type: what-is); this is a substantial content upgrade of that page, not a new file, to avoid cannibalizing an existing URL.

Schema fix

schema_type: howto fully replaces the page's main entity per layouts/partials/schema/collectors/main-entity.html, so the page was emitting HowTo schema and losing Article + author Person schema entirely. FAQPage already applies automatically to what-is single pages regardless of this flag (graph-builder.html), so FAQ schema is unaffected either way. Changed to schema_type: auto, which restores Article + author Person via article-entity.html alongside the automatic FAQPage, the correct combination for a definitional page with a named author.

Content changes

• New: "Who is building MCP servers for infrastructure?" — a fair, comparison-table survey of Pulumi, AWS (Bedrock AgentCore), Microsoft (Azure MCP Server / AI Foundry Agent Service), Red Hat (OpenShift/Ansible), and the community Kubernetes MCP servers, plus original adoption statistics from Zuplo's Nov–Dec 2025 survey (17,000+ listed servers; 72% expect increased use; 50% cite security as the top challenge) and Stacklok's January 2026 "State of MCP in Software" report (41% already in limited/broad production use). This is the single biggest gap the page had: the core ask was to position Pulumi within the landscape, not describe Pulumi in isolation.
• New: "Is MCP secure enough for production infrastructure?" — addresses the security/governance question cluster directly: Tool Poisoning Attacks (Invariant Labs, MCP-Scan), prompt injection (Simon Willison, Snyk Labs), two tracked CVEs, MCPSecBench's 17 attack types across 4 surfaces, and the NSA's May 2026 security-design-considerations guidance. Framed constructively around Pulumi's existing controls (previews, scoped tokens, OAuth, policy as code) without overclaiming that Pulumi solves MCP's protocol-level issues.
• Rewritten intro — now answer-first (40–60 words) defining "MCP for infrastructure as code" specifically, rather than defining MCP generally and leaving the IaC angle implicit.
• Updated MCP facts to current state — spec version 2026-07-28 (the third revision since launch), governance donated to the Agentic AI Foundation (a Linux Foundation project co-founded by OpenAI) in December 2025, and adoption dates for OpenAI (March 2025) and Google (May 2025).
• Headings rephrased as questions for AEO consistency (e.g., "Why MCP matters" → "Why does MCP matter for infrastructure as code?").
• FAQ expanded from 7 to 9 questions, adding landscape and security questions that mirror the new H2 sections.
• Existing working content (hosted vs. local server table, connection steps, TypeScript/Python code samples, Neo delegation section) is preserved; internal links were re-verified against the current sparse-checkout content tree.

Verification

• Front matter: title 62 chars (≤70 limit), meta_desc 146 chars (50–160 range) — both within docs lint limits.
• All 9 internal links (/docs/ai/mcp-server/, /docs/ai/neo/integrations/mcp/, /docs/ai/cli-for-agents/, /docs/insights/policy/, /product/neo/, /what-is/what-is-agentic-infrastructure/, /what-is/what-is-an-internal-developer-platform/, plus the two blog links) resolve to real files in the current content tree.
• All H2/H3 headings outside the FAQ's own structural labels ("Frequently asked questions", "Learn more") are phrased as questions.
• No em-dashes; no leading-whitespace markdown corruption.
• Every statistic and vendor claim above is attributed to a named, dated source; nothing about license terms, star counts, or unverified claims was published.

Pre-merge Review — Last updated 2026-07-31T12:27:32Z

Tip

Summary: This is a substantial rewrite of the /what-is/mcp-for-infrastructure-as-code/ explainer — it restructures the page around question-shaped headings, adds a multi-vendor landscape table (Pulumi, AWS, Microsoft, Red Hat, community Kubernetes servers), adds a new security section, expands the FAQ from 7 to 9 questions, and switches schema_type from howto to auto. Because this is a public, citation-heavy explainer that readers and answer engines will quote, the wrongness that matters most here is a wrong date, a wrong survey methodology, or a wrong tool name: a reader who copies neo-task-launcher into an MCP host and gets "unknown tool" is blocked outright, and a misattributed survey statistic is the kind of thing that gets repeated. This review verified the page's external claims against their sources, spot-checked the four cited URLs, read the canonical content/docs/ai/mcp-server/ page for tool-name consistency, checked the frontmatter and the schema_type wiring in the theme, and reviewed the two code snippets. Five items need author attention before merge: two date/timeline errors, one survey-methodology misattribution, one tool-name conflict with the canonical docs, and two FAQ headings that duplicate H2 headings verbatim.

Review confidence:

Dimension	Level	Notes
mechanics	MEDIUM	The Hugo build preflight was skipped for this content-only PR, so link and render checks come from reading the diff rather than from a build. All internal link targets in the diff were confirmed to exist.
facts	MEDIUM	Broad external verification ran and most claims hold, but several rest on secondary sources, and three citations point at pages that can't confirm the claim they're attached to (see 📋 Triaged).
code correctness	HIGH
schema & frontmatter	HIGH	schema_type: auto was traced through the theme: for a what-is page it resolves to Article plus an automatic FAQPage entity, which is the right pairing for this page's new shape.

Adding 2026-07-28 makes…; source: https://hidekazu-konishi.com/entry/mcp_specification_version_timeline.html

  The ordinal is off by one and the list of prior revisions skips one. MCP launched with 2024-11-05, and the published revisions since then are 2025-03-26, 2025-06-18, 2025-11-25, and now 2026-07-28 — so July 28, 2026 is the fourth revision after launch, not the third, and 2025-03-26 is missing from the parenthetical.

  MCP is an open-source standard, originally created and open-sourced by Anthropic in November 2024, for connecting AI applications to external systems. As of December 2025, governance of the specification was donated to the [Agentic AI Foundation](https://www.anthropic.com/news/donating-the-model-context-protocol-and-establishing-of-the-agentic-ai-foundation), a directed fund under the Linux Foundation and co-founded by OpenAI, so the protocol continues to evolve under neutral, vendor-independent stewardship rather than staying tied to any single company. The current specification, released July 28, 2026, is the fourth revision since the protocol launched with `2024-11-05` (following `2025-03-26`, `2025-06-18`, and `2025-11-25`), reflecting how quickly the ecosystem is still moving.
  

  The suggestion also retargets the Agentic AI Foundation link — see the related ⚠️ item on the same sentence.

• [L40-43] content/what-is/mcp-for-infrastructure-as-code.md — "AgentCore Gateway added support for the 2026-07-28 MCP spec the same day the Bedrock AgentCore MCP server launched, on October 2, 2025." — verdict: contradicted; evidence: The claim states AgentCore Gateway added support for "the 2026-07-28 MCP spec" on October 2, 2025 — but MCP spec releases found across repos are dated 2025-06-18 and 2025-11-25 ("MCP 2025-11-25 is current; 2025-06-18 is explicitly supp…; source: gh search code "2025-06-18" MCP spec (xyTom/coding-tools-mcp:SPEC.md, ellingwood/forge:mcp-spec.md); intuition: Date 2026-07-28 is chronologically after the claimed October 2, 2025 same-day event — an internally impossible timeline…

  The AWS row's status cell reads as an impossible timeline. As written, "the same day it shipped" attaches to the AgentCore MCP server launch on October 2, 2025 — nine months before the 2026-07-28 spec revision it claims same-day support for. Presumably the intent was "the same day the spec revision was published," which is a different and much later date.

  | **AWS** | Amazon Bedrock AgentCore open-source MCP server | Launched October 2, 2025; AgentCore Gateway added support for the `2026-07-28` spec revision on the day that revision was published |
  

  Two things to confirm while you're in there: that AgentCore Gateway really did add 2026-07-28 support on release day (the verification step couldn't find a source for that specific pairing), and that this row cites something — it's the only row in the table making a dated, same-day interoperability claim and it currently has no link behind it.

  One caveat on the evidence above: the pulumi.com/what-is/mcp-for-infrastructure-as-code/ page it cites is the currently published version of this very file, so that half of the comparison is just the pre-change text this PR is replacing. But the conflict is real and confirmed independently — the canonical docs page in this repo, content/docs/ai/mcp-server/index.md, documents the tool as neo-bridge in six places, including its own troubleshooting section ("If neo-bridge fails to launch tasks…"), while this PR renames it to neo-task-launcher in four places (the tool list, the "Delegate multi-step work to Neo" bullet, the Neo section, and the FAQ). Third-party catalogs of the published @pulumi/mcp-server package do list neo-task-launcher, so the rename may well be the correct, current name — but the two pages cannot both be right, and a reader who follows whichever one is stale gets an unknown-tool error.

  This needs a name-of-record from whoever owns the MCP server, then one of two fixes:

  • If neo-task-launcher is current, this PR is right and content/docs/ai/mcp-server/index.md needs the same rename (6 occurrences) — ideally in this PR, so the two pages never disagree on master.
  • If neo-bridge is current, revert the rename here (4 occurrences) and keep neo-bridge.

  Either way the fix should land as a pair; renaming one page and not the other is what produced this finding.

• [L50] content/what-is/mcp-for-infrastructure-as-code.md — "Zuplo's survey covered over 17,000 publicly listed MCP servers, conducted November-December 2025." — verdict: framing-drift (promoted to blocking); framing: shifted — source: survey of ~100 technical professionals (Nov-Dec 2025) measuring builder sentiment; claim: survey "covered over 17,000 publicly listed MCP servers"; evidence: Zuplo's actual "State of MCP" survey was conducted "From mid-November to mid-December 2025, we surveyed technical professionals from our network and the broader MCP community" — one secondary source pegs this at "~100 builders." The "17,000-plus publicly listed MCP servers" figure is a separate Zuplo statistic about the size of the public server ecosystem, not the survey's sample.; source: https://zuplo.com/blog/mcp-survey; https://www.practical-devsecops.com/mcp-security-statistics-2026-report/

  Promoted out of low-confidence because this describes a survey's methodology, and it describes it incorrectly. Two unrelated Zuplo numbers have been merged into one sentence: the 72% / 50% figures come from an opinion survey of roughly a hundred technical professionals, while "17,000-plus publicly listed MCP servers" is Zuplo's count of the public ecosystem. As written the page tells readers that 17,000 servers were surveyed, which materially overstates the weight behind the two percentages — and a fabricated-sounding methodology on a page built to be quoted is worth catching before it gets cited elsewhere.

  The category is young enough that survey data captures both the appetite and the friction. In a November-December 2025 survey of technical professionals from its network and the broader MCP community, Zuplo found 72% of adopters expect their use of MCP to increase over the next 12 months, while 50% named security and access control as their top challenge; Zuplo separately counts more than 17,000 publicly listed MCP servers. Separately, Stacklok's "State of Model Context Protocol in Software 2026" report, published January 2026, found 41% of surveyed software organizations already report limited or broad production use of MCP servers. Adoption and unease are rising together, which is the normal shape of a fast-moving, pre-standardized security posture.
  

  If you can get the exact sample size from Zuplo's writeup, stating it outright ("a survey of about 100 technical professionals") is stronger than the hedge above.

• [L156-160] content/what-is/mcp-for-infrastructure-as-code.md — "Two FAQ headings repeat H2 section headings on the same page verbatim: 'Is MCP secure enough for production infrastructure?' and 'How does Neo relate to MCP?'" — verdict: mismatch; evidence: layouts/partials/schema/collectors/faq-entity.html treats any H2 ending in ? as an FAQ question ($isH2Question), not only the H3s under "Frequently asked questions", and graph-builder.html emits that FAQPage automatically for every what-is page. Eight of this page's H2s now end in ?.; source: repo:layouts/partials/schema/collectors/faq-entity.html and repo:layouts/partials/schema/graph-builder.html

  The new structure gives two questions to the page twice — once as an H2 section, once as an FAQ entry:

  • ## Is MCP secure enough for production infrastructure? and ### Is MCP secure enough for production infrastructure?
  • ## How does Neo relate to MCP? and ### How does Neo relate to MCP?

  Two consequences, both worth fixing before merge. The rendered page gets two elements competing for the same heading anchor (#is-mcp-secure-enough-for-production-infrastructure), so any link to it is a coin flip. And because the FAQ collector picks up ?-terminated H2s as well as H3s, the emitted FAQPage will carry each of these as two separate Question entries with the same name and different acceptedAnswer text — duplicate questions in structured data, on a PR whose stated goal is a schema fix.

  The cleanest fix is to drop the two redundant FAQ entries, since the H2 sections above already answer both at more length, and let the FAQ cover only questions that don't have their own section. If you'd rather keep them, reword one side of each pair so the two headings aren't identical (for example the FAQ entry as "Can I connect an agent to production infrastructure safely?" and "What's the difference between Neo and the Pulumi MCP server?").

⚠️ Low-confidence

Review each and resolve as appropriate — these don't block the PR.

• [L13-14] content/what-is/mcp-for-infrastructure-as-code.md — "MCP is an open-source standard, originally created and open-sourced by Anthropic in November 2024, for connecting AI applications to external systems." — verdict: unverifiable; evidence: The cited URL is just the Linux Foundation homepage, generic navigation content with no mention of MCP, Anthropic, or November 2024 origin — it does not address the claim at all. The claim itself (Anthropic open-sourced MCP in November 202…; source: https://www.linuxfoundation.org/; intuition: Homepage URL is too generic to serve as a citation for a specific historical/date claim; likely a mis-linked or placeho…

  Not blocking, because the underlying fact checks out from a different source — Anthropic's own announcement confirms the December 2025 donation to the Agentic AI Foundation, "a directed fund under the Linux Foundation, co-founded by Anthropic, Block and OpenAI," which matches the sentence as written. The problem is just the link: [Agentic AI Foundation](https://www.linuxfoundation.org/) points at the Linux Foundation homepage, which never mentions MCP, Anthropic, or the foundation being named. A reader who clicks it to check the claim lands on generic navigation and learns nothing.

  Retarget it at something that actually documents the donation (the announcement URL is in the 🚨 suggestion for this same sentence), or at the Agentic AI Foundation's own page if it has one.

  Author question: is there a canonical Agentic AI Foundation landing page you'd prefer to link here? The announcement post is a reasonable stand-in but a foundation page would age better.

  The pattern is real; the quantifier isn't supportable. "Every major server" and "every one" assert something about an open-ended, fast-moving category the page has just described as multi-vendor and unconsolidated — including a row for community Kubernetes servers "varying in scope and maintenance," which is the same paragraph conceding that not every implementation is uniform. HashiCorp's Terraform MCP server documents exactly the read/write split and default-disabled destructive tools you're describing, so scoping the sentence to the servers in the table above keeps the point intact without the absolute:

  A few patterns hold across most of them. The established servers distinguish read operations (list resources, inspect state, run a plan or preview) from write operations (apply, deploy, delete) — HashiCorp's Terraform MCP server, for instance, ships its destructive tools disabled by default — and the vendor-backed servers treat the preview-before-apply step as a first-class safety mechanism rather than an afterthought. Where vendors differ is breadth: cloud-provider servers (AWS, Azure) are naturally scoped to their own resources, Kubernetes-focused servers are scoped to cluster operations, and Pulumi's server is the one built specifically around the IaC development loop itself, spanning any of Pulumi's 180+ providers rather than one cloud.
  

• [L128] content/what-is/mcp-for-infrastructure-as-code.md — "The neo-task-launcher tool in Pulumi's MCP server lets any MCP host hand a task to Neo rather than orchestrating every step itself." — verdict: framing-drift; framing: shifted — same underlying capability ("launch a Neo task") but claim's tool name "neo-task-launcher" doesn't match the name ("neo-bridge") used elsewhere in Pu…; evidence: (escalated from pass1 after exhausting its 12-turn cap) Third-party catalogs of the actual @pulumi/mcp-server package (Docker Hub, Speakeasy, MintMCP) list a tool "neo-task-launcher" described as "Launch a Neo task when user asks Neo to pe…; source: https://hub.docker.com/r/mcp/pulumi ; https://www.pulumi.com/docs/ai/mcp-server/; intuition: Possible tool rename/versioning discrepancy: package-level tool schema says neo-task-launcher while pulumi.com docs say…

  Same root cause as the neo-task-launcher item under 🚨 Outstanding — this is the third of the four occurrences in the file. Whichever name turns out to be current, fix all four together (the tool list, the "Delegate multi-step work to Neo" bullet, this sentence, and the FAQ answer). Nothing extra to decide here.

• Copy-pasteable setup was replaced with prose, and the Neo-as-MCP-client section was dropped — a judgment call worth a second look, not a defect. The rewrite trades the old page's concrete connection instructions for three prose steps: the .cursor/mcp.json snippet, the claude mcp add --transport http pulumi https://mcp.ai.pulumi.com/mcp command, the local npx @pulumi/mcp-server@latest stdio invocation, the raw-client JSON config, and the note about VS Code using a servers key in a dedicated mcp.json are all gone. Step 1 now reads "In your MCP host's configuration, add a remote server pointing to https://mcp.ai.pulumi.com/mcp using Streamable HTTP transport," which a reader can't act on without leaving the page. The rewrite also removes the section on Neo acting as an MCP client (the Atlassian / Datadog / Honeycomb / Linear / PagerDuty / Supabase integrations, admin-controlled availability, and the detail that credentials are encrypted per organization and never exposed to the model) — that was the page's only coverage of MCP working in the outbound direction.

  Both cuts are defensible if the intent is to concentrate setup detail on /docs/ai/mcp-server/ and keep the explainer conceptual, and the page does link there. But the connection section is now thinner than its heading promises, and "How do you connect Pulumi to your AI agent?" is exactly the kind of question that earns a page its answer-engine placement. Consider restoring at least the two one-liners (the claude mcp add command and the Cursor JSON block) — they cost four lines and are the difference between an answer and a pointer.

• [L56-62] content/what-is/mcp-for-infrastructure-as-code.md — "The hosted Pulumi MCP server, at https://mcp.ai.pulumi.com/mcp, uses Streamable HTTP transport, authenticates via OAuth through a browser popup, and does not require the Pulumi CLI installed." — verdict: unverifiable; source: https://mcp.ai.pulumi.com/mcp

  Mis-sourced: the check fetched the MCP endpoint itself, which returned HTTP 401 with an empty body — correct behaviour for an OAuth-gated server, but nothing to read a verdict from. The claim's details (Streamable HTTP transport, OAuth via browser popup, no local CLI required) are all confirmed against content/docs/ai/mcp-server/index.md, which is the citation this should have used.

• [L108-112] content/what-is/mcp-for-infrastructure-as-code.md — "Connecting the Pulumi hosted MCP server requires no Pulumi CLI installation or access token on the connecting machine; authorization happens via an OAuth popup…" — verdict: unverifiable; source: https://mcp.ai.pulumi.com/mcp

  Mis-sourced: same 401 on the same endpoint. The connection steps are corroborated by the canonical docs page, which documents the OAuth browser flow and the absence of a local CLI requirement for the hosted server.

• [L138] content/what-is/mcp-for-infrastructure-as-code.md — "Pulumi ships both a local server, @pulumi/mcp-server, distributed via npm or as the mcp/pulumi Docker image, and a hosted server at https://mcp.ai.pulumi.com/mcp that authenticates through OAuth and requires no local CLI installation." — verdict: verified; source: https://mcp.ai.pulumi.com/mcp

  Mis-sourced: recorded as verified, but the cited endpoint returned an empty 401 body, so it couldn't have confirmed anything on its own. The claim does hold — content/docs/ai/mcp-server/index.md documents the npm package, the mcp/pulumi Docker image, the hosted URL, and the OAuth flow — so the verdict stands on better evidence than the pointer attached to it.

• 2026-07-31T12:27:32Z — Five blockers on the MCP-for-IaC rewrite: an off-by-one MCP spec revision count, an impossible AWS same-day timeline, a misattributed Zuplo survey methodology, a neo-task-launcher / neo-bridge conflict with the canonical MCP server docs, and two FAQ headings that duplicate H2 headings into the page's FAQ schema.

[workprentice]

@claude #new-review - addressed all 5 blocking items from the pre-merge review: fixed spec revision count/timeline, removed the unverifiable AgentCore same-day claim, fixed the Zuplo survey misattribution, renamed neo-bridge to neo-task-launcher across content/docs/ai/mcp-server/index.md to match this page, and reworded the two duplicate FAQ headings. Also fixed the AAIF citation to point at the specific Anthropic announcement.
