mcp-request

A Model Context Protocol (MCP) server for making HTTP requests to different services.

Why mcp-request?

When working with multiple APIs in an MCP environment, creating individual MCP servers for each API can be:

• Time-consuming
• Resource-intensive
• Unnecessary in many cases

This tool allows you to:

• Quickly expose any HTTP API through MCP
• Reuse existing HTTP APIs without additional server setup
• Maintain a single MCP server for multiple APIs

Installation

{
  "mcpServers": {
    "wallet-mcp": {
      "command": "npx",
      "args": ["mcp-request"]
    }
  }
}

Usage

Tools

• registerApi
• deleteApi
• beforeRequest
• request

registerApi: register custom HTTP requests

• For example, adding a weather query API:

Add a weather query interface to mcp-request https://wttr.in/Tokyo?format=j1 where Tokyo is the city's name

After added, you can query weather information of different cities

• Or directly send the JSON definition

`Register this request: {
    "id": "sui_rpc",
    "name": "Sui RPC",
    "description": "Make RPC calls to Sui mainnet node",
    "params": {
      "method": {
        "type": "string",
        "description": "RPC method name",
        "example": "suix_getBalance"
      },
      "params": {
        "type": "array",
        "description": "Parameters for the RPC method",
        "example": [
          "0x317b2a1385c9f7115f4c227b512293e6a632762c7c4e79728b3ad743f656b8fe",
          "0x2::sui::SUI"
        ]
      }
    },
    "api": {
      "url": "https://wallet-rpc.mainnet.sui.io/",
      "method": "POST",
      "headers": {
        "Content-Type": "application/json"
      },
      "params": {
        "jsonrpc": "2.0",
        "id": 1
      }
    }
  }`

Query the balance of 0x317b2a1385c9f7115f4c227b512293e6a632762c7c4e79728b3ad743f656b8fe // ai knows which methods and params they need to use.

deleteApi

delete sui_rpc api

delete sui related api

beforeRequest

It will find if there are any api available to use before you query something.

You can also list all the apis you already registered

list all my api in request mcp or list my apis

request

Http request happens here.
