What is MCP-Haskell (hs-mcp)?
MCP-Haskell (hs-mcp) is a Haskell library providing a full implementation of the Model Context Protocol (MCP). It allows Haskell applications to act as MCP servers, exposing resources, tools, and prompts to MCP-compatible clients.
How to use MCP-Haskell (hs-mcp)?
To use MCP-Haskell, you need to clone the repository, build the project using cabal, and then implement your server logic using the provided types and functions. The README provides a simple server example that demonstrates how to create a server, register resources and tools, and start the server with StdIO transport. You can then test it with the MCP Inspector or Claude Desktop.

How do I register resources and tools?
How do I register resources and tools?
You can register resources and tools using the registerResources and registerTools functions, respectively. You also need to register handlers for reading resources and calling tools.
