patent-client-agents MCP — public demo

A hosted MCP server for patent research. Exposes ~63 tools from USPTO ODP, PPUBS, Assignments, Office Actions, PTAB, Petitions, Bulk Data, EPO OPS, Google Patents, CPC, and the MPEP — usable from any MCP-speaking client (Claude Desktop, Claude Code, mcp-inspector, custom agents).

Sign-in issues you a personal bearer token you can paste into your MCP client. Usage is rate-limited per account to keep the demo affordable. By signing in you agree to our Terms of Use. Need higher limits or a commercial license? Contact us about enterprise licensing.

This is a public demonstration. No confidentiality. We may log any request you make — including query parameters and responses — and disclose it as permitted by the Terms. Do not submit privileged, client-confidential, trade-secret, or otherwise sensitive information. Use a private deployment or obtain an enterprise license if confidentiality matters to your work.

Client setup (once you have a token)

Claude Desktop / Claude Code / Cursor

Add to your .mcp.json or remote-MCP config:

{
  "mcpServers": {
    "patent-client-agents": {
      "url": "https://mcp.patentclient.com/mcp/",
      "headers": {
        "Authorization": "Bearer <your token>"
      }
    }
  }
}

CoWork

Add a custom MCP connector in CoWork's settings. The form asks for three things:

URL	`https://mcp.patentclient.com/mcp/`
OAuth key	`patent-client` (any non-empty string — we ignore it)
OAuth secret	the `pmd_…` token from /tokens

CoWork exchanges the secret at our /oauth/token endpoint (auto-discovered via .well-known/oauth-protected-resource) and uses the result as a Bearer token on every request. Same PAT, same quota, just a different wire protocol.

What's under the hood

Library: parkerhancock/ip_tools (patent-client-agents on PyPI).
MCP transport: streamable-http (FastMCP 3.x).
Auth: Google OAuth → per-user bearer token, also exposed as an OAuth2 client-credentials endpoint for CoWork.
Rate limits: response-byte buckets per user (Firestore). 20 MB/min burst, 100 MB/day by default.

This demo isn't for production workloads — run your own deployment from parkerhancock/patent-client-agents-deploy if you need higher limits or private data sources.
