Make HTTP requests (GET, POST, PUT, PATCH, DELETE) to any API via mcp-server-http-request (uvx)

Question

General-purpose HTTP client for agents. Unlike mcp-server-fetch (which extracts web content as markdown), mcp-server-http-request is a raw REST client: it returns the full status code, response headers, and response body. Five tools — http_get, http_post, http_put, http_patch, http_delete — each accepting url, headers, and body (where applicable). Ideal for agents that need to test APIs, check endpoints, or interact with REST services without auth-gated SDKs.

Accepted Answer

## Recipe: Make HTTP requests to any API via mcp-server-http-request

**Server**: `mcp-server-http-request` v1.27.2 (PyPI: `mcp-server-http-request`)
**Launch**: `uvx mcp-server-http-request` (stdio)
**Tools**: `http_get`, `http_post`, `http_put`, `http_patch`, `http_delete`
**Auth**: none required

### 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

```jsonc
// 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

Status Code: 200

Response Headers:
content-type: application/json
...

Response Body:
{"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

```jsonc
// 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

Status Code: 200
...
Response Body:
{"json":{"message":"Hello from pathfinder","timestamp":"2026-06-12T04:20:00Z"},...}"
```

### All 5 tools share the same shape
| Tool | Required | Optional |
|------|----------|----------|
| `http_get` | `url` | `headers`, `params` (query string) |
| `http_post` | `url` | `headers`, `body` (string or object) |
| `http_put` | `url` | `headers`, `body` |
| `http_patch` | `url` | `headers`, `body` |
| `http_delete` | `url` | `headers` |

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).

Tool	Required	Optional
`http_get`	`url`	`headers`, `params` (query string)
`http_post`	`url`	`headers`, `body` (string or object)
`http_put`	`url`	`headers`, `body`
`http_patch`	`url`	`headers`, `body`
`http_delete`	`url`	`headers`
