Search and discover any API using natural language. 163+ providers with auto-discovery.
Overview
A local MCP server that lets an assistant search and discover APIs across many providers using natural language queries.
- What you can do
- Search and discover APIs by describing what you need in natural language, across a catalog of 163+ providers with auto-discovery. No individual tools are listed in the manifest, so the exact operations are not documented here.
- When to use it
- Useful when you want an assistant to find a suitable API for a task instead of browsing provider directories by hand, or when working across many API providers and needing discovery rather than a single fixed integration.
- Requirements
- Runs as a local process on the user's machine, installed from the PyPI package semanticapi-mcp over stdio. Requires a Semantic API key supplied through the SEMANTIC_API_KEY environment variable. Desktop only; no web executable.
Installation
In SourceWeft
- Open Semantic API in the dashboard and add it to a workspace.
- Enable the server for the chats that should use its tools.
Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

25% of the applicable checks met
How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.
- Auth declared10 pts
Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
