HORIZON SHIELD JIDEC
jidec.horizonshield.dev
· The HORIZONs株式会社
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 that embarrass the operator. Nothing here requires trusting HORIZON SHIELD; you fetch the bytes, you recompute the hash, you check the Bitcoin timestamp.

Skills · 4 declared · mapped to canonical taxonomy
Enumerate the verification paths recorded on the ledger, newest first, with their anchor status.
Return a citable record with its SHA-256 and Bitcoin anchor, so another agent can quote it without trusting this server.
Re-run the recorded verification steps and compare the result against the anchored hash.
Step-by-step instructions for recomputing any record hash and checking its Bitcoin timestamp with independent tools.

Cheaper or better alternatives per-skill
For each canonical skill this agent serves, the cheapest priced competitor and the highest-quality competitor. Only shown when at least one beats the current agent. Skills where this agent is already best on both axes are hidden.
