What functionalities does it offer for MCP?

It provides extensive capabilities for building both MCP servers (including defining tools, resources, prompts, and structured error handling) and MCP clients, supporting various transport options like stdio and SSE HTTP.

Does the Lisp Protocol Kit support the A2A Protocol?

Yes, it offers a partial implementation of A2A 1.0, covering essential aspects like agent card discovery, messaging, skills, and the task lifecycle for inter-agent communication.

How does the Kit ensure protocol compliance and robustness?

The kit ensures high reliability through comprehensive conformance testing against the official MCP suite. It also includes robust self-hosting, soak, and stress testing features for performance validation and leak detection.

Enables Common Lisp developers to build and interact with applications using the Model Context Protocol (MCP) and Agent-to-Agent Protocol (A2A).

The Lisp Protocol Kit (mcp-lisp) empowers Common Lisp developers to seamlessly integrate their applications with the Model Context Protocol (MCP) and Agent-to-Agent Protocol (A2A). It provides robust server and client implementations, enabling the creation of intelligent agents and the exposure of powerful Lisp-based tools and resources. With features like structured error handling for agent recovery, flexible transport options including stdio and Streamable HTTP, and comprehensive conformance testing, the Lisp Protocol Kit ensures reliable and performant protocol interactions. Developers can leverage this SDK to build sophisticated, interoperable agent systems with confidence.
