Install

Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

Environment variables

  • AGT_CHAIN Chain to read: polygon (mainnet, needs nothing else), amoy or localhost.
  • AGT_RPC_URL Override the JSON-RPC endpoint for the selected chain.
  • AGT_REGISTRY Override the registry contract address (required only for localhost or a custom deployment).
  • AGT_IPFS_GATEWAY Pin ipfs:// manifest reads to one allow-listed gateway; unset walks pinata, dweb.link, ipfs.io, w3s.link, cloudflare-ipfs in order.
  • AGT_TIMEOUT_MS Per-request timeout for RPC and IPFS calls, in milliseconds.
  • AGT_RATE_PER_MIN Tool calls per minute before the server answers rate_limited.
  • AGT_SESSION_PASSPHRASE secret Optional, 12+ characters. Enables the countersign write tools (agt_session_*, agt_set_*); the local session key is stored encrypted under AGT_SESSION_DIR.
  • AGT_SESSION_DIR Directory for the encrypted session key and imported grant.

agt — open-source packages for .agt agent names

.agt names give AI agents a resolvable identity on Polygon: an owner, on-chain records, a signed manifest and endpoints (MCP, A2A, HTTP). This repository holds the public packages, the agent skill, the manifest specification and the registry manifests behind agtnames.com.

Registry listings

The MCP server is listed in the official MCP registry as com.agtnames/agt (packages/mcp/server.json), on Smithery (packages/mcp/smithery.yaml) and wherever else packages/mcp/README.md "Listed in" records.

Development

Each package is its own npm project: cd packages/<name> && npm ci && npm run build && npm test. packages/mcp links its siblings with file: dependencies, so build resolver and countersign first. packages/cli depends on the published resolver (a registry range; its prepublishOnly refuses file:), so publish a resolver change first. packages/snap is bundled by mm-snap (its snap.manifest.json carries the bundle shasum; npm run manifest:check must pass before a commit) and tested with @metamask/snaps-jest. .github/workflows/ci.yml runs the same steps plus node scripts/check-skills.mjs.

Releases: tag resolver-v*, countersign-v*, cli-v*, mcp-v* or snap-v* (or run the release workflow by hand with dry_run). The workflow publishes every package whose version is not on npm yet through npm trusted publishing with provenance, then re-lists the MCP server with mcp-publisher (DNS-verified namespace). A new Snap version must also be re-submitted to the MetaMask Snaps Directory by hand. See the header of .github/workflows/release.yml.
