| Summary: Connect Perl with AI using MCP (Model Context Protocol) | |
Connect Perl with AI using the Model Context Protocol (MCP). Currently this
module is focused on tool calling, but it will be extended to support other
MCP features in the future. At its core, MCP is all about text processing,
making it a great fit for Perl.
Streamable HTTP Transport
Use the MCP::Server/"to_action" method to add an MCP endpoint to any
Mojolicious application. The tool name and description are used for
discovery, and the at https://json-schema.org is used to validate the
input.
use Mojolicious::Lite -signatures;
use MCP::Server;
my $server = MCP::Server->new;
$server->tool(
name => 'echo',
description => 'Echo the input text',
input_schema => {type => 'object', properties => {msg => {type => 'string'}}, required => ['msg']},
code => sub ($tool, $args) {
return "Echo: $args->{msg}";
}
);
any '/mcp' => $server->to_action;
app->start;
Authentication can be added by the web application, just like for any
other route. To allow for MCP applications to scale with prefork web
servers, server to client streaming is currentlly avoided when
possible.
Stdio Transport
Build local command line applications and use the stdio transport for
testing with the MCP::Server/"to_stdio" method.
use Mojo::Base -strict, -signatures;
use MCP::Server;
my $server = MCP::Server->new;
$server->tool(
name => 'echo',
description => 'Echo the input text',
input_schema => {type => 'object', properties => {msg => {type => 'string'}}, required => ['msg']},
code => sub ($tool, $args) {
return "Echo: $args->{msg}";
}
);
$server->to_stdio;
Just run the script and type requests on the command line.
