Build with FuzeMCP

FuzeMCP turns any REST API into an MCP (Model Context Protocol) server. No SDKs to install, no MCP protocol knowledge required — just your existing API.

Quick Start

1. Create an account — Sign up for free at fuzemcp.dev
2. Create a project — Give it a name and point it to your API base URL
3. Define your tools — Map your API endpoints to MCP tool definitions
4. Get your endpoint — We generate a hosted MCP endpoint for you
5. Connect your client — Add the endpoint to Claude, Cursor, VS Code, or any MCP client

Every request to your MCP endpoint requires an API key. Include it in the Authorization header:

Authorization: Bearer <your-mcp-api-key>

You can manage API keys in your project settings. Keys are scoped per project and can be rotated at any time.

Header Forwarding

FuzeMCP automatically forwards the headers you configure to your upstream API. Set up custom headers in the project dashboard.

Tools are the core of your MCP server. Each tool maps to an API endpoint with a defined schema.

Tool Schema

{
  "name": "get_product",
  "description": "Fetch product details by reference",
  "inputSchema": {
    "type": "object",
    "properties": {
      "reference": {
        "type": "string",
        "description": "Product reference code"
      }
    },
    "required": ["reference"]
  }
}

Mapping to Your API

Configure how each tool calls your API — method, path, headers, and how to map input parameters to request fields.

Your hosted MCP endpoint works with any client that supports the Model Context Protocol.

Supported Clients

• —Claude Desktop — Add to claude_desktop_config.json
• —Cursor — Settings → MCP → Add server
• —VS Code — Add to .vscode/mcp.json
• —Windsurf — Windsurf → Settings → MCP
• —OpenCode — Add to opencode.json or .opencode.json

Each client uses a standard JSON-RPC 2.0 connection to your FuzeMCP endpoint.

FuzeMCP exposes a standard JSON-RPC 2.0 compliant endpoint. All requests use POST with a JSON body.

Endpoint

POST https://api.fuzemcp.dev/mcp/your-project-id
