ContextMCP

ContextMCP is a self-hosted MCP server that indexes documentation from various sources to provide AI agents with current and structured context for queries.

ContextMCP is a self-hosted MCP server that creates a queryable brain from documentation. It indexes data at set intervals to ensure AI agents operate with current information and avoid outdated context. Unlike standard retrieval-augmented generation systems that blindly chunk text, this tool uses AST-based parsers. These parsers recognize code blocks, headers, and semantic boundaries to maintain logic integrity. The system operates on Cloudflare Workers for low-latency retrieval. It functions by processing a simple configuration file placed within a repository.
