MCP support
This project is an MCP server that exposes the query_chat_messages tool, letting MCP clients query and summarize chat messages.
Configuration
Local server config is the same for every client. Copy it into your client’s MCP config file.
We haven’t collected a package or remote endpoint for this server. Follow the instructions in the project README.
Tools
Local servers expose tools only once running on your machine, and the maintainer has not provided a tool list.

"mcp-server-chatsum": {
"command": "path-to/bin/node",
"args": ["path-to/mcp-server-chatsum/build/index.js"],
"env": {

Debugging
Since MCP servers communicate over stdio, debugging can be challenging. We recommend using the MCP Inspector, which is available as a package script:
pnpm inspector
The Inspector will provide a URL to access debugging tools in your browser.

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
