Evermint tools (5)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

  • evermint_get_record

    Fetch the full contents of a single EverMint record by Record ID, including the original payload that was minted. Requires authentication and the record must belong to the authenticated org. Use this when an agent needs to retrieve the actual content of a prior decision or action it recorded.

  • evermint_list_records

    List EverMint records belonging to the authenticated account. Supports filtering by agent_id, action_type, and date range. Returns record IDs, action types, timestamps, and agent IDs, not full payloads. Use this when an agent needs to audit its own past actions or build context from prior decisions.

  • evermint_mint

    Mint a tamper-evident, cryptographically timestamped record of an AI agent action, decision, or observation. Returns a Record ID and SHA-256 hash that can be used to prove what the agent did and when. Use this whenever an agent takes an action that may need to be audited, disputed, or verified later.

  • evermint_verify

    Verify an existing EverMint record by Record ID. Confirms the record exists, has not been altered, and returns its metadata. No API key required, verification is public.

  • evermint_verify_chain

    Verify the integrity of a sequence of hash-chained EverMint records. Confirms each record's hash matches its content, and that each record correctly references the prior record in the chain with no gaps or tampering. Use this to prove an entire sequence of agent decisions is intact, not just a single record. This is public, no API key required.

evermint_verify({ record_id: "EVR-12C5N1A2" })

evermintlistrecords (API key required)

List records for the authenticated org with optional filters. Returns metadata only (no payloads).

evermint_list_records({
  agent_id: "billing-agent-1",
