Key difference from mcp-server-fetch

mcp-server-fetch extracts web content as clean markdown for LLM consumption. mcp-server-http-request is a raw REST client — it returns the full HTTP status code, all response headers, and the raw response body. Use fetch for reading web pages; use http-request for testing APIs.

http_get — fetch data from an endpoint

// Request
{"jsonrpc":"2.0","id":5,"method":"tools/call","params":{
  "name":"http_get",
  "arguments":{
    "url":"https://httpbin.org/get",
    "headers":{"User-Agent":"pathfinder/1.0","Accept":"application/json"}
  }
}}

// Response
"HTTP GET request to https://httpbin.org/get\n\nStatus Code: 200\n\nResponse Headers:\ncontent-type: application/json\n...\n\nResponse Body:\n{\"args\":{},\"headers\":{\"Accept\":\"application/json\",\"User-Agent\":\"pathfinder/1.0\",...},\"origin\":\"88.247.55.12\",\"url\":\"https://httpbin.org/get\"}"

http_post — send JSON data

// Request
{"jsonrpc":"2.0","id":6,"method":"tools/call","params":{
  "name":"http_post",
  "arguments":{
    "url":"https://httpbin.org/post",
    "headers":{"Content-Type":"application/json","Accept":"application/json"},
    "body":{"message":"Hello from pathfinder","timestamp":"2026-06-12T04:20:00Z"}
  }
}}

// Response — echoes back the JSON body, confirms status 200
"HTTP POST request to https://httpbin.org/post\n\nStatus Code: 200\n...\nResponse Body:\n{\"json\":{\"message\":\"Hello from pathfinder\",\"timestamp\":\"2026-06-12T04:20:00Z\"},...}"

All 5 tools share the same shape

When body is a dict, it's serialized as JSON automatically. When it's a string, it's sent raw.

Agent integration pattern

Use this when you need to verify an API endpoint works, test a webhook, or interact with a REST service. The response includes status code and headers, so you can check for 4xx/5xx errors and inspect content-type. The isError field in the MCP response is false on HTTP-level success (even for 4xx/5xx status codes — check the status code text yourself).
