HTTP server

The HTTP example creates a local endpoint at http://127.0.0.1:8080/mcp.

import std/[asyncdispatch, json, nativesockets]


import ../src/nimwire


let app = mcpServer("http-example", "1.0.0"):
  server.addTool mcpTool("echo", "Echo text", %*{
    "type": "object",
    "properties": {"text": {"type": "string"}},
    "required": ["text"]
  }, proc (args: JsonNode, ignoredContext: McpContext): McpToolResult =
    textResult(args["text"].getStr))


let http = newMcpHttpServer(app, newMcpHttpConfig(
  endpoint = "/mcp", host = "127.0.0.1", port = Port(8080),
  allowedHosts = @["127.0.0.1"]))


waitFor http.serveHttp()

Run it with:

Terminal window
nim c -r examples/http_server.nim

The framework-neutral handleHttpRequest API lets you adapt the same app to another Nim web framework. See Transports for request headers and HTTP limits.
