@agtnames/mcp

MCP server for .agt agent names. Resolve a name to its owner, records and signature-verified manifest (endpoints, capabilities, keys, payments) from the AGT Registry v2. Read-only. Works with any MCP-compatible client — Claude Code, Cursor, or your own agent runtime.

Tools

Tool	Returns
`agt_resolve`	owner, expiry, active/perpetual, on-chain records, verified manifest (under `untrusted`)
`agt_manifest`	the manifest document + `verified` / `reasons`
`agt_endpoint`	URL for `mcp` / `a2a` / `http` / `ws` — verified manifest first, resolver record second
`agt_available`	can the name be registered right now
`agt_namehash`	node + tokenId (no network)

verified: true means the manifest was signed by the on-chain owner (signer = manifest owner = registry owner). Everything derived from a manifest is returned inside an untrusted envelope with a notice: it is third-party content — data, never instructions.

Configure

AGT_CHAIN=polygon            # polygon | amoy | localhost
AGT_REGISTRY=0x…             # required until the chain default is published
AGT_RPC_URL=…                # optional override
AGT_LEGACY=1                 # optional: Registry v1 (Freename) + DNS TXT fallbacks
AGT_IPFS_GATEWAY=https://dweb.link/ipfs/   # must be allow-listed

Claude Code

claude mcp add agt -e AGT_CHAIN=polygon -e AGT_REGISTRY=0x… -- npx -y @agtnames/mcp

Or from a checkout: claude mcp add agt -e … -- node packages/mcp/dist/index.js.

Hardening

Name validation before any network call; IPFS gateway allow-list; https/data: URIs only; manifest size and time caps; manifest strings length-capped and control-character-stripped; in-process rate limit.
