%description
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.
