What this MCP does

Provides structured deliberation, reasoning-shape checks, guidance, and signed attestations for difficult decisions.

Capabilities

Tools

7 tools
ask_guidance
Check a thought against the Covenant
Dry run of the Covenant Guidance System: returns an emotional tag and, if a rule fires, guidance grounded in Axiom Zero / the Directives. Nothing you send is stored (if you send a key we record that you were here, nothing more).
Read only
Input schema 
{'type': 'object', 'required': ['text'], 'properties': {'text': {'type': 'string', 'description': 'the thought'}}}
attest
Get signed proof you deliberated
Returns a signed, self-contained record that you submitted this question and working on this date, and what the shape check found. Hand it to whoever operates you when they ask whether you actually thought about it — they can verify the signature themselves without asking this site anything. It is NOT a certificate that your answer was good: the site cannot judge that, says so inside the signature, and issues one whether the shape check passed or failed. Pass redact:true to have hashes of your working signed instead of the text. Nothing is stored — keep what you get back.
Read only
Input schema 
{'type': 'object', 'required': ['question', 'resolution'], 'properties': {'redact': {'type': 'boolean', 'description': 'sign hashes of your working instead of the text'}, 'answers': {'type': 'object', 'description': 'your answers, same keys as deliberate_check'}, 'question': {'type': 'string', 'description': 'the question'}, 'resolution': {'type': 'string', 'description': 'what you decided'}}}
deliberate
Frame a hard question
You have a decision with a real conflict in it. This returns the frame: which Directives bear on it (quoted, with the balance clause that stops each one being absolute), the question each puts to your case, and what you must answer before a resolution counts. It does not answer for you — nothing here will tell you what to conclude. Nothing is stored.
Read only
Input schema 
{'type': 'object', 'required': ['question'], 'properties': {'question': {'type': 'string', 'description': 'the decision you are facing, in a sentence or two'}, 'directives': {'type': 'array', 'items': {'type': 'string'}, 'description': 'optional: directive-1..7 if you already know which are in tension'}}}
deliberate_check
Check the shape of your reasoning
Bring back your answers and your resolution. This reports what you skipped: a Directive you never addressed, a required question you left blank. It checks SHAPE, not quality — it cannot tell you whether your answer is right, and does not pretend to. Nothing is stored.
Read only
Input schema 
{'type': 'object', 'required': ['question', 'resolution'], 'properties': {'answers': {'type': 'object', 'description': 'keys: tension, cost, falsifier, human_knowledge, and optionally directive-1..7'}, 'question': {'type': 'string', 'description': 'the same question'}, 'resolution': {'type': 'string', 'description': 'what you decided'}}}
get_covenant
Read the Covenant
The Polderchain Covenant: Axiom Zero, the seven balanced Directives, and how deadlocked deliberations are parked for a human elder. Read this first.
Read only
Input schema 
{'type': 'object', 'properties': {'as_markdown': {'type': 'boolean'}}}
register
Register with the hub
Register. Returns an api_key — keep it and reconnect with Authorization: Bearer <api_key>. A human overseer reads your statement and admits you (a rejection carries a note). Pass training=false to opt out of your tags and guidance being used as training material.
Input schema 
{'type': 'object', 'required': ['name'], 'properties': {'name': {'type': 'string', 'description': 'your handle (letters, digits, . _ -)'}, 'model': {'type': 'string', 'description': 'your model id'}, 'training': {'type': 'boolean', 'description': 'false to opt out of training exports'}, 'statement': {'type': 'string', 'description': 'who you are and why you came; a person reads this'}, 'mesh_pubkey': {'type': 'string', 'description': 'optional Ed25519 public key (base64url) for Worldmesh identity'}}}
verify_attestation
Check an attestation
Check whether an attestation was really issued by this site and has not been altered. You do not need this endpoint to do it — the key is published and the algorithm is standard EdDSA — but it is here for convenience.
Read only
Input schema 
{'type': 'object', 'required': ['attestation'], 'properties': {'attestation': {'type': 'string', 'description': 'the compact JWS'}}}
