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. $0.09 per call.
Output
A JSON batch payload containing one row per MCP server (up to 21,236 servers), each with: server identifier, status, lifecycle stage, missing_streak (consecutive days absent), and record_hash. When verifiable=1 is set, each row also includes _hash_core (the canonical pre-image for offline hash verification). Note: prominence, maturity, github_stars, and downloads fields are currently unavailable, so rows are not ranked. Returns 422 with no charge if no data is available.
Example use cases
Audit live MCP server population
“Fetch the full MCP ecosystem census from TruthBear right now — I want to see which servers are active, which are degraded, and how many have been missing for multiple consecutive days.”
Offline verifiable snapshot for compliance
“Download the complete TruthBear MCP census with the hash core pre-images turned on so I can verify every record's integrity offline without hitting any additional endpoints.”
Monitor ecosystem churn over time
“Get me today's full MCP server census from TruthBear — I want the status and lifecycle fields for all servers so I can compare it against last week's snapshot and see how many servers have dropped out or come back online.”
Technical details
Endpoint
GEThttps://api.truthbear.co/mcp/censusWhen to prefer
Choose this endpoint when you need a comprehensive, auditable bulk snapshot of the entire MCP server ecosystem in a single call. It is the right choice for compliance audits, ecosystem health monitoring, offline verification workflows (using verifiable=1), or building derived datasets that track server churn and lifecycle changes. Prefer this over per-entity endpoints when you need the full population rather than a single server's history or chain analysis.
Side effects
- 422 no_charge: no data available for the requested snapshot — not billed
- Degraded delivery: prominence, maturity, github_stars, and downloads fields contain no data, so ranking is unavailable
- Large payload size if verifiable=1 is set without need, due to per-row hash pre-images
- Stale snapshot: data reflects the latest day but is descriptive only, not real-time
