APIWeaver MCP Server

If you already use APIWeaver, the apiweaver mcp server is the piece that lets your assistant work with it directly. A FastMCP server that dynamically creates MCP (Model Context Protocol) servers from web API configurations. This allows you to easily integrate any REST API, GraphQL endpoint, or web service into an MCP-compatible tool that can be used by.

What the server does

• 🚀 Dynamic API Registration: Register any web API at runtime
• 🔐 Multiple Authentication Methods: Bearer tokens, API keys, Basic auth, OAuth2, and custom headers
• 🛠️ All HTTP Methods: Support for GET, POST, PUT, DELETE, PATCH, and more
• 📝 Flexible Parameters: Query params, path params, headers, and request bodies
• 🔄 Automatic Tool Generation: Each API endpoint becomes an MCP tool
• 🧪 Built-in Testing: Test API connections before using them

Installation

Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client. The configuration blocks on this page cover the common clients.

Where it fits

Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. It is maintained by GongRzhe; worth a glance at recent repository activity before you build anything load-bearing on it.

SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.

Worth knowing first

• It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
• Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.
