Overview

AI-generated 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.
Before you install
The server requires a secret API key (SEMANTIC_API_KEY) that is sent to the Semantic API service; keep it out of shared logs and configuration. Queries are sent to a third-party service, so avoid including sensitive information in search text. No tools are listed, so review what it can do before installing.

Installation

In SourceWeft

  1. Open Semantic API in the dashboard and add it to a workspace.
  2. 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.

SourceWeft has not started this package in its sandbox yet, so its tools are not known.

Score

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.

  • Reached in the last 30 days25 pts

    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.
