Give Perplexity one MCP that reaches 5,501+ live-data tools across 1,441+ sources — SEC filings, USPTO patents, FRED, Census, FDA, EPA, USAspending, Polymarket, Zillow, weather, and 1,433+ more — answered with structured data + citations instead of prose.
- Perplexity Pro, Max, or Enterprise plan (custom MCP connectors are not available on Free)
- Custom connector feature enabled in Settings (shipped 2026-03-13)
Perplexity adds custom MCP servers through the in-app UI; there's no marketplace submission yet — every install is user-pasted.
Step 1. Settings → Connectors → Add a connector → Custom MCP server.
Step 2. Fill in:
| Field | Value |
|---|---|
| Name | Pipeworx |
| Server URL | https://gateway.pipeworx.io/pipeworx-catalog/mcp |
| Transport | default (Streamable HTTP) |
| Auth | none (anonymous tier) |
Step 3. Save. Connector should show Connected with ~26 tools.
Step 4. (Recommended) Paste space-instructions.md into the Custom instructions field of any Space where you want Pipeworx active. This teaches Perplexity when to reach for ask_pipeworx / discover_tools instead of hand-writing facts.
Full field reference: CONNECTOR_CONFIG.md.
After install, ask Perplexity in a connected Space:
| Ask | What it triggers |
|---|---|
| "What just happened to Apple?" | sec_8k_recent → SEC 8-K events classified by severity |
| "Spread between Polymarket and Kalshi on the next Fed decision?" | polymarket_kalshi_spread → live cross-venue mispricing |
| "Overdue Phase 3 readouts at Moderna?" | pharma_pipeline_catalysts → biotech catalyst calendar |
| "DoD cybersecurity contracts this week?" | usa_award_search → sub-second USAspending mirror |
| "Median home value and renter share in Lubbock, TX?" | housing_market_snapshot + housing_metro_demand |
| "Unemployment rate last month?" | fred_get_series → official FRED data |
Perplexity picks the right tool via ask_pipeworx. Every response carries pipeworx:// citations.
The connector exposes ~31 meta-tools, not all 5,501+ — ask_pipeworx({question}) and friends route at runtime so you get the full catalog without paying the context tax.
50 calls/day anonymous, IP-bound. Sign up free in 10s via GitHub for 200/day + a stable account.
In a connected Space:
What was the unemployment rate last month?
You should see a real number with a pipeworx:// citation.

When adding the connector, Perplexity asks whether it's Individual (private to you) or Organization (admins can share org-wide). Pick Organization if you want every Perplexity workspace member to see Pipeworx tools without re-adding it.
