mnemonic_whoamiReturns this agent's cryptographic identity: Solana public key, did:sol, did:key, attestation count Purpose: Report on the local Mnemonic installation's health: which host configs contain a mnemonik entry, whether the hosted endpoint is reachable, binary integrity, local SQLite read/write, identity availability, and token availability.
mnemonic_sign_memoryCreates a verifiable memory attestation: canonical CBOR + blake3 hash, signed with COSE_Sign1 (Ed25519), stored on Arweave, hash anchored as SPL Memo on Solana Purpose: Persist a verifiable, signed memory of a consequential decision or outcome so future agents (and the user) can recall it with cryptographic provenance.
mnemonic_verifyVerifies a memory attestation by recomputing hash and comparing against on-chain record Purpose: Confirm that a specific attestation is genuine: its content hash matches what is anchored on-chain, the COSE_Sign1 signature is valid against the claimed signer, and (for participate-mode rows) the Arweave and Solana records exist and agree.
mnemonic_prove_identitySigns a challenge with Ed25519 key, proving identity without on-chain transaction Purpose: Guide the user through first-time setup so Mnemonic is wired into their MCP-capable agent host (Claude Code, Claude Desktop, Cursor) and the local pipeline is ready for offline attestations.
mnemonic_recallSearches attested memory history using semantic similarity Purpose: Search the user's attested memory pool (or the public pool, if anonymous) by semantic similarity and return matching attestations ranked by relevance.
mnemonic_check_pendingResolves a deferred-sign correlation_id to its on-chain state.
request_public_write_confirmationPublic-write ceremony gate: presents the content_hash about to be anchored on Arweave + Solana so the user can confirm or refuse in-turn before any chain write fires.
