INDIVIDUAL MCP TOOL

emem_verify_receipt

Verify a signed receipt envelope server-side: rebuilds the canonical preimage under the rule the receipt's OWN `preimage_version` names (v2, current: tagged length-prefixed segments plus a segment binding the inclusion proof; v1: the same without that segment; absent/0: the legacy `request_id | served_at | primitive | cells, | fact_cids,` concatenation), runs ed25519 over the embedded pubkey + signature, and returns `{valid, reason, failure_detail, signature_valid, merkle_proof_valid, signer_pubkey_b32, preimage_blake3_hex}`.

emem_entity — Give a real-world object (a bridge, a farm plot, a river, a named place) a single, shared, content-addressed identity that any agent resolves the same way.
emem_locate — Mint the canonical, vendor-neutral address (cell64) for a real-world place: the shared spatial identity every agent resolves to identically, so two models refer to the same ground instead of two descriptions of it.
emem_recall — Read the signed facts at a canonical address (cell64); auto-materializes on a miss for any band with a registered materializer.
emem_memory_token — Mint a citation handle, `emem:fact:<cell64>:<fact_cid>` (or `:<state_cid>`), that any agent or LLM resolves to the byte-identical signed object.
emem_memory_token_resolve — Parse a `emem:fact:<cell64>:<fact_cid>` citation handle and return the reading it cites.
emem_memory_contradictions — Surface where the corpus DISAGREES with itself (algebra: competing evidence).
emem_guard_verdict — Run emem-guard's policy pipeline over text you are about to send, against this responder's corpus.
