Naming Signal is a Model Context Protocol (MCP) server: Evidence-first naming: briefs, sprints, exact domain checks, finalist research. Read-only. As an MCP server it plugs straight into AI assistants, exposing its functionality as tools the model can invoke on your behalf.
You can run Naming Signal two ways: connect to the hosted endpoint at https://namingsignal.com/mcp with no local install, or run it on your own machine via the npm package @namingsignal/mcp. Configuration happens through environment variables — you'll need NAMING_SIGNAL_API_KEY. The current release is v0.2.0.
You'll find Naming Signal in the Development category here on mcp.site; it connects to Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and any other MCP client — see the install snippets below.
