How this service works
[BATCH+PROOF] MCP server graveyard - servers that vanished from the census. THRESHOLD stated plainly: listed on FIRST confirmed absence (confirm_absences=1), not multi-day confirmation; only two snapshot days exist. record_hash is null on these rows (imported from a surviving registry, the original collector never produced hashes). Descriptive only, never a forecast or advice. No data -> 422 no_charge, not billed.
Output
Returns a JSON object containing: `count` (integer total of confirmed-dead servers), `deaths` (array of dead server records from census snapshots dated 2026-07-07/08), and `record_hash_verifiable` (object exposing computed hash metadata for self-verification of the records against the surviving registry).
Example use cases
Audit MCP ecosystem for defunct servers
“Show me all the MCP servers that have disappeared from the census — I want to know which ones are confirmed dead so I can clean up any integrations pointing to them.”
Research MCP server mortality rate
“How many MCP servers have died according to the graveyard registry? Give me the full list and the count so I can analyze the churn rate in the ecosystem.”
Verify a specific server's status
“I want to cross-check whether any of the MCP servers on my integration list have been flagged as dead in the graveyard — can you fetch the full death roll so I can compare?”
Technical details
Endpoint
GEThttps://aeml-x402.zeabur.app/mcp/graveyardWhen to prefer
Use this endpoint when you need a curated, payment-gated list of MCP servers confirmed absent from census snapshots — particularly useful for ecosystem health audits, cleaning up stale integrations, or researching MCP server churn. Prefer this over manual polling or broader infrastructure monitoring tools when you specifically want a point-in-time death registry with verifiable record hashes.
Side effects
- Payment failure (x402 protocol): call rejected if 0.5 USDC payment on Base not included
- Empty deaths array if snapshot window yields no confirmed absences
- Network timeout if the zeabur.app host is unreachable
- Potential stale data since snapshots only cover two days (2026-07-07/08)
