How this service works
Truth Bear reports facts and their official sources — screening-grade, verifiable, not predictions or advice. Pay per call with USDC (x402) or a 30-day access pass by card / Apple Pay / Google Pay / PayPal.
Output
Returns a JSON object with fields: status (e.g. active, missing, deprecated), missing_streak (count of consecutive missed census cycles), lifecycle (e.g. stable, experimental, deprecated), and record_hash. Some fields (prominence, maturity, github_stars, downloads, source_code_url) are currently unavailable due to collector deprecation and will appear in an unavailable_fields list. If the requested server has no data, a 422 no_charge error is returned without billing.
Example use cases
Check if an MCP server is still active
“I want to know if the MCP server '0580iris-lang-x711' is still active or if it's been deprecated — can you look up its census record and tell me its status and lifecycle?”
Audit MCP server health before integration
“Before I integrate with an MCP server called 'my-tool-server-x99', can you check its TruthBear census record to see its current status and how many consecutive missing cycles it has?”
Verify record hash for MCP server reproducibility
“Can you fetch the census record for MCP server 'delta-bridge-z204' and give me its record_hash so I can verify it matches what I have on file?”
Technical details
Endpoint
GEThttps://api.truthbear.co/mcp/serverWhen to prefer
Use this endpoint when you need a point-in-time census record for a specific MCP server by ID, including its operational status, lifecycle classification, missing streak, and record hash. Prefer this over general web searches when you need structured, machine-readable registry data about MCP server health and lifecycle. Best suited for agent workflows that need to audit, validate, or catalog known MCP servers before integration or monitoring decisions.
Side effects
- 422 no_charge — server ID not found in census, no data available, not billed
- Missing or invalid 'name' query parameter causes a request error
- Degraded delivery: prominence, maturity, github_stars, downloads, source_code_url fields always absent due to collector shutdown
- Stale snapshot: data reflects 2026-07-08 snapshot, not real-time state
