How this service works
[BATCH+PROOF] Full MCP ecosystem census (21,236 servers, latest day): status, lifecycle, missing_streak, record_hash. DEGRADED DELIVERY, see unavailable_fields - prominence, maturity, github_stars and downloads have no data, so rows are no longer ranked. Snapshot 2026-07-08. Descriptive only, never a forecast or advice. No data -> 422 no_charge, not billed.
Output
A JSON object containing a 'rows' array of all MCP server records (up to 21,236 entries) with fields including server status, lifecycle state, missing_streak (consecutive days absent from crawl), and record_hash; plus a 'count' integer indicating total records returned. Note: prominence, maturity, github_stars, and downloads fields are unavailable due to collector shutdown.
Example use cases
Audit active vs inactive MCP servers
“Give me the full MCP server census so I can see which servers are still active and which have gone missing recently — I want the lifecycle and missing_streak data for all of them.”
Research MCP ecosystem size and health
“How big is the MCP ecosystem right now? Pull the latest census snapshot so I can see the total server count and their overall status distribution.”
Build a filtered MCP server directory
“I'm building a directory of MCP servers — can you fetch the complete census of all known MCP servers with their status, lifecycle, and record hash so I can filter and index them myself?”
Technical details
Endpoint
GEThttps://aeml-x402.zeabur.app/mcp/censusWhen to prefer
Use this endpoint when you need a comprehensive, population-level view of all known MCP servers in a single call — ideal for ecosystem analysis, server discovery, health monitoring, or building downstream indexes. Prefer this over targeted search endpoints when you need the full corpus rather than a filtered subset. Note that prominence-based sorting is unavailable; if you need ranked results by popularity or stars, this endpoint cannot fulfill that need.
Side effects
- Payment failure (x402 USDC payment not completed — endpoint requires $0.5 USDC per call)
- Timeout on large payload (~21k rows may be slow on poor connections)
- Stale data — snapshot is fixed at 2026-07-08 so real-time accuracy is not guaranteed
- Missing fields for prominence/maturity/github_stars/downloads returned as null or omitted per unavailable_fields
