About

Signa is the global trademark API, built for developers and AI agents. This hosted MCP server lets Claude, ChatGPT, Cursor and other MCP clients search and read trademark records from the world's registers, including USPTO, EUIPO, WIPO and UKIPO, in one format.

What you can do

Search trademarks by name, class, owner, status and office, with fuzzy, phonetic and lookalike-character matching. Each result shows why it matched.
Read the full record: status, goods and services, classes, owners, attorneys, events and proceedings.
Research owners and their portfolios, with registry owners linked to the companies behind them.
Look up attorneys and law firms and the marks they represent.
Find the Nice classes for a product or service, and check goods and services wording.
Check office rules such as deadlines, prosecution steps and opposition periods.
Monitor marks with watches and alerts (API key).

Who it's for

Trademark attorneys and paralegals, brand and legal teams, founders checking a name, and developers building trademark tools.

The data

Records come straight from the official registries and are kept current. Every record carries its source date, and Signa publishes which offices it covers. Ask Signa which offices are live, or see the docs.

Connect

Server URL: https://api.signa.so/mcp (Streamable HTTP, hosted, nothing to install)

Sign in with your Signa account (OAuth). For scripts and headless clients, use an API key instead. Free to start, no card required, with simple, public pricing.

Claude Code

claude mcp add --transport http signa https://api.signa.so/mcp

Claude.ai and Claude Desktop: Settings → Connectors → Add custom connector, paste https://api.signa.so/mcp, sign in. Or add Signa from the Claude directory.

ChatGPT (plans with MCP connectors): add a connector with https://api.signa.so/mcp and choose OAuth.

Cursor (.cursor/mcp.json)

{ "mcpServers": { "signa": { "url": "https://api.signa.so/mcp" } } }

VS Code (.vscode/mcp.json)

{ "servers": { "signa": { "type": "http", "url": "https://api.signa.so/mcp" } } }

API key instead of OAuth (any client that accepts headers)

{ "headers": { "Authorization": "Bearer sig_YOUR_KEY" } }

Clients that only run local (stdio) servers

npx mcp-remote https://api.signa.so/mcp

Example prompts

Is BRIGHTLY already registered for software in the US, EU or UK? Check classes 9 and 42.
Which Nice classes should a company selling smart home cameras and a subscription app file in?
Find marks similar to AURORA in class 9 at EUIPO, including ones that sound alike.
Show the full record for US trademark 1939139: status, owner, classes and recent events.
List Nike's trademarks at UKIPO with their current status.
List TTAB oppositions filed against marks owned by Apple Inc. in the last 12 months.
How long is the opposition period at EUIPO, and when does it end for this application?
