AnyEvent::MCP - Model Context Protocol client/server support |

|
|

|
|
=head1 SYNOPSIS |
| 6 |
|
|
|
| 7 |
|
|
use AnyEvent::MCP::Server::Simple; |
| 8 |
|
|
|
| 9 |
|
|
mcp_tool ... |
| 10 |
|
|
mcp_stdio; |
| 11 |
|
|
|
| 12 |
|
|
or use the object interface directly: |
| 13 |
|
|
|
| 14 |
|
|
use AnyEvent::MCP::Server; |
| 15 |
|
|
|
| 16 |
|
|
my $server = AnyEvent::MCP::Server->new (...); |
| 17 |

|
=head1 DESCRIPTION |
| 19 |
|
|
|
| 20 |
|
|
AnyEvent::MCP provides event-driven Model Context Protocol client and server |
| 21 |
|
|
support. |
| 22 |
|
|
|
| 23 |
|
|
The usual way to implement a small MCP server is |
| 24 |
|
|
L<AnyEvent::MCP::Server::Simple>, which provides a function-based interface and |
| 25 |
|
|
creates the underlying server objects when a transport such as stdio or HTTP is |
| 26 |
|
|
started. |
| 27 |
|
|
|
| 28 |
|
|
The lower-level object interfaces are intended for applications that need to |
| 29 |
|
|
manage MCP connections, servers or reusable tool registries directly. |
