Description

This repository provides a Model Context Protocol (MCP) server exposing tools and resources to access Slack's search functionality. It offers tool endpoints to list users and channels, fetch channel messages and thread replies, and perform full-text message searches, plus resource URIs for all users and channels. The server is built to run on the Bun runtime and requires a Slack API token; it includes error handling for auth, rate limits, and network issues and avoids exposing the token in logs.
