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.
| Path | What | Install |
|---|---|---|
packages/resolver | @agtnames/resolver: resolve, verify and read manifests; A2A agent card and ERC-8004 export helpers; agt-resolve CLI | npm i @agtnames/resolver |
packages/mcp | @agtnames/mcp: MCP server (stdio) with five read-only tools; the hosted Streamable-HTTP endpoint is https://agtnames.com/api/mcp | npx -y @agtnames/mcp · claude mcp add --transport http agt https://agtnames.com/api/mcp |
packages/countersign | @agtnames/countersign: scoped session grants for record writes (EIP-7702 + Delegation Framework caveats) | npm i @agtnames/countersign |
packages/snap | @agtnames/snap: MetaMask Snap that resolves name.agt in the send field to the name's on-chain address (Polygon and the major EVM chains) | MetaMask Flask until allowlisted: wallet_requestSnaps with npm:@agtnames/snap |
skills/agt-names | Agent skill teaching when and how to use the tools and the public API | npx skills add agtnames/agt |
spec/ | The .agt manifest specification (v3 draft, v1 frozen); rendered at agtnames.com/spec | |
gemini-extension.json | Gemini CLI extension bundling the MCP server | gemini extensions install https://github.com/agtnames/agt |

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/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*, 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.
