Official Go SDK for MCP in Development, Stable Release Expected in August
The official Go SDK for the Model Context Protocol is in development, with a stable, production-ready release expected by August 2025.
This module provides standard "HTTP proxy" logic. You can script your own server
using the proxy
server API. Be sure to take a look at the "Examples" section
below.
There is also a companion proxy(1)
CLI tool, which spawns an HTTP(s) proxy
server with the specified options.
You could think of proxy(1)
as similar to some of the other popular open
source HTTP proxy software:
A basic HTTP(s) server with all the default options. All requests are allowed. CONNECT HTTP method works as well.
import * as http from 'http';
import { createProxy } from 'proxy';
const server = createProxy(http.createServer());
server.listen(3128, () => {
var port = server.address().port;
console.log('HTTP(s) proxy server listening on port %d', port);
});
The proxy(1)
CLI tool can be used to spawn HTTP(s) proxy server instances with
various options.
Pass the -p
/--port
option to with a port number to specify a TCP port to
bind to. Defaults to 3128 if none is specified.
$ proxy --port 8080
Proxy-Authenticate
commandPass the -a
/--authenticate
switch with a command to execute when the client
Proxy-Authorization
header is given. This command determines whether or not the
request is authorized based on the "exit code" of the command.
The relevant request authentication information is passed in as
PROXY_AUTH_USERNAME
, PROXY_AUTH_PASSWORD
and PROXY_AUTH_SCHEME
environment
variables.
For example, to authorize "Basic" authentication with username "foo" and password "bar":
$ proxy --authenticate 'if \
[ "$PROXY_AUTH_USERNAME" = "foo" ] && \
[ "$PROXY_AUTH_PASSWORD" = "bar" ]; \
then exit 0; \
fi; \
exit 1;'
Pass the -l
/--local-address
argument with an IP address of the network
interface to send the outgoing requests through. It is the equivalent of setting
a localAddress
field in the options when calling http.request()
.
$ proxy --local-address 192.168.0.10
