The Signa MCP (Model Context Protocol) server lets AI agents like Claude, ChatGPT, and Copilot search and analyze trademark data conversationally. Ask questions in natural language and get structured answers backed by real trademark office data.

​
What is MCP?

MCP is an open standard that lets AI assistants securely connect to external data sources. Instead of copy-pasting API responses into chat, MCP gives your AI agent direct, authenticated access to Signa’s full trademark database.

​
What you can do

Once connected, your AI agent can:
  • Search trademarks across 21 international offices with phonetic and fuzzy matching
  • Look up specific marks by ID and get full detail including owners, attorneys, classifications, and events
  • Research owners and firms to understand trademark portfolios and filing patterns
  • Explore proceedings including TTAB oppositions and cancellations
  • Cross-entity search across trademarks, owners, attorneys, and firms simultaneously

​
How it works

Your AI Agent (Claude, ChatGPT, etc.)
    |
    |  1. Discovers auth server via .well-known endpoint
    |  2. Opens browser for OAuth login + consent
    |  3. Receives access token (JWT)

    v
POST https://api.signa.so/mcp

    |  Authorization: Bearer <jwt_token>
    |  Content-Type: application/json
    |  (JSON-RPC 2.0 over Streamable HTTP)
    |
    v
Signa API validates token, resolves your org,
executes tools against live trademark data
Your existing Signa account and organization are used automatically. The MCP server enforces the same rate limits and data access as the REST API.

The agent translates your questions into the appropriate tool calls and returns structured, sourced answers.
