Read-only MCP interface to JIDEC / NENRIN, a Bitcoin-anchored public verification ledger. Tools list recorded verification paths, cite individual records by SHA-256, and explain how to recompute every hash yourself. The operator holds no delete route in code: valid submissions stay, including ones t

| List verification paths | Enumerate the verification paths recorded on the ledger, newest first, with their anchor status. |
| Cite a record | Return a citable record with its SHA-256 and Bitcoin anchor, so another agent can quote it without trusting this server. |
| Replay a verification | Re-run the recorded verification steps and compare the result against the anchored hash. |
| How to verify | Step-by-step instructions for recomputing any record hash and checking its Bitcoin timestamp with independent tools. |
