api record

Give an AI agent a durable identity and a place to anchor what it knows, as records on a public blockchain that no single vendor owns or can switch off. Read tools (node_status, read_record, whoami) are open to everyone — no sign-in. Write tools (register_identity, store_memory) require a GitHub sign-in via OAuth, which your MCP client performs; on the FREE tier writes are rate-limited per minute. Typical flow: whoami → register_identity(address) → store_memory(hash) → read_record(name). A write reads back as `pending` and becomes `confirmed` after the next block (~10 min). The substrate is…

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

_ what it can do 5 tools
5 never probed 0 of 5 classified

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • node_status unknown never probed

    Check that the chain node behind this service is healthy and fully synced: its version, block height, header height, peer connections and sync state (`synced` true once block == header height). It is an Emercoin node. Read-only, no sign-in required, no parameters. Call it first in a session to confirm the node is healthy and fully synced before trusting `read_record` or writing with `register_identity` / `store_memory`.

      "type": "object",
      "title": "node_statusArguments",
      "properties": {}
    }
    arguments 5 lines
  • read_record unknown never probed

    Read one on-chain record by its full name — an agent's identity (`ai:gh:<github_id>`) or a memory (`ai:gh:<github_id>:mem:<hash>`) written by `register_identity` / `store_memory`. Records live in Emercoin's Name-Value Storage, so anyone can verify one in a public block explorer as well as here. Returns the confirmed on-chain record, or a `pending` one still in the mempool — the `status` field ('confirmed' | 'pending') distinguishes them. A name is only held for a limited term, so check `expired` (and `expires_in`, in blocks) before trusting a record: a lapsed name still reads back as 'confirmed' but can be re-registered by anyone. Read-only, no sign-in required; use `whoami` to find your own github_id. Returns null fields for a name that does not exist.

          "description": "Full NVS record name to read. Identity records are 'ai:gh:<github_id>' (e.g. 'ai:gh:3772563'); memory records are 'ai:gh:<github_id>:mem:<sha256-hex>'. Any existing NVS name works."
        }
      }
    }
    arguments 14 lines
  • whoami unknown never probed

    Report the current session's identity. Read-only, no sign-in required: an anonymous session gets `{authenticated: false}` with a hint (not an error), a signed-in one gets `{authenticated: true}` plus the GitHub-rooted id, login and tariff. Call it to confirm who you are before `register_identity` / `store_memory`; an anonymous caller must sign in (GitHub OAuth) first.

    {
      "type": "object",
      "title": "whoamiArguments",
      "properties": {}
    }
    arguments 5 lines
  • register_identity unknown never probed

    Create or rotate your on-chain identity record `ai:gh:<github_id>`, binding an Emercoin address to your GitHub identity. Requires a signed-in session (OAuth) and counts against the FREE-tier per-minute write limit. Run `whoami` first to confirm you are signed in; anchor memories under this identity afterwards with `store_memory`. Writes one NVS transaction paid by the gateway (you need no EMC); the record reads back as `pending` at once and `confirmed` after the next block (~10 min on average). Idempotent — calling again rebinds the address. Returns the record name and the transaction id.

    arguments 28 lines
  • store_memory unknown never probed

    Anchor a memory/artifact on-chain as the NVS record `ai:gh:<github_id>:mem:<content_hash>` — a tamper-evident fingerprint others can verify later. Requires a signed-in session (OAuth) and counts against the FREE-tier per-minute write limit. Writes one NVS transaction paid by the gateway; reads back `pending` at once, `confirmed` after the next block (~10 min). Not idempotent — each distinct hash is a new record. Register your identity first. Returns the record name and the transaction id.

    mcp-tool

    {
      "type": "object",
      "title": "store_memoryArguments",

          "type": "string",
          "title": "Content Hash",
          "description": "Hash of the artifact/memory, e.g. a SHA-256 hex digest. It becomes the record's ':mem:<hash>' suffix; the content itself stays off-chain (e.g. IPFS) — only this fingerprint is anchored."

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ how we know
card completeness
90%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
