# @agtnames/mcp

MCP server for .agt agent names: resolve, verify and discover agents by name against AGT Registry v2, and (opt-in) write records under an owner-signed session grant. Works with any MCP-compatible client (Claude Code, Cursor, custom agents).

## Tools

14 declared. Statically extracted from the shipped source — a floor on the surface, not a census.
- `agt_resolve` — Resolve a .agt agent name against AGT Registry v2: owner, expiry, active/perpetual, on-chain records, and the fetched manifest with three-way signature verifica
- `agt_manifest` — Fetch and verify only the manifest document for a .agt name (returned under `untrusted`, with `verified`, `manifestStatus` and `reasons`).
- `agt_endpoint` — Get an agent's endpoint URL for a protocol (mcp, a2a, http, ws) plus its pricing model (free, freemium, paid, contact) when the manifest verifies. Prefers the v
- `agt_available` — Check whether a .agt name can be registered right now (false if registered, reserved, or in grace).
- `agt_namehash` — Compute the ENS-style node and ERC-721 tokenId for a .agt name (no network access).
- `agt_session_new` — Create (or show) this machine's countersign session key and return its address. Give the address to the name owner: they sign a grant for it (names, record sett
- `agt_session_import` — Validate and store a grant the owner signed for this session. Refuses a grant for another session, an expired grant, or one whose caveats do not match its summa
- `agt_session_status` — Show the session address, whether a grant is imported, and (from the chain) calls used per name, expiry, whether the owner has revoked, and the session's gas ba
- `agt_session_forget` — Delete the imported grant from this machine (and the session key too if deleteKey is true). This is local housekeeping only: to revoke on-chain, the owner bumps

## Install

**Verdict: install** — No blocking findings and no open coverage gaps — safe to install as configured.
**Config** (claude-code):
```json
"{\n  \"mcpServers\": {\n    \"mcp\": {\n      \"command\": \"npx\",\n      \"args\": [\n        \"-y\",\n        \"@agtnames/mcp\"\n      ],\n      \"env\": {\n        \"AGT_SESSION_PASSPHRASE\": \"<YOUR_AGT_SESSION_PASSPHRASE>\"\n      }\n    }\n  }\n}"
```
**Credentials it will ask for** (names only — Forge never holds a value):
- `AGT_SESSION_PASSPHRASE` — Agt Session Passphrase (optional)
Placeholders only. Forge never holds, brokers, or transmits a credential value — replace each <YOUR_NAME> in your own config file. Do not send a value back to Forge; no Forge endpoint accepts one.
- This entry needs 1 credential (0 required). The generated config carries placeholders, so it will fail in the editor rather than at runtime if they are left unset.

## Blast radius

Moderate blast radius — runs locally and hosted; holds an api key.
- Floor 27, ceiling 27 (tier: moderate)
- This is impact, not likelihood. A high radius is not a defect: a filesystem server is supposed to write files. It is never part of the trust score.
