## Description

codebase-memory-mcp is a Model Context Protocol server that indexes source repositories into a persistent code knowledge graph, giving AI coding agents a queryable map of symbols, call paths and architecture so they read fewer files. Parsing uses bundled tree-sitter grammars covering more than 160 languages, and a built-in type layer links calls to their true definitions without a separate language server. Everything runs locally, with no cloud service or API key.

Beyond the core graph, it offers read-only Cypher-style queries that return clear errors for unsupported syntax, and semantic code search that combines bundled embeddings, full-text ranking and structural filters. It maps code changes to affected symbols and their blast radius, finds dead code, and selects which tests a change reaches, falling back to broader runs when evidence is weak. It also links services across repositories over HTTP, gRPC, GraphQL, tRPC and messaging channels, and connects Kubernetes, Terraform, Docker and similar configuration back to source.

Agent setup is automated: the tool detects supported coding clients and installs their server connections, instructions, skills, profiles and fail-open hooks that never block a tool call. A shared per-account background daemon watches files and re-indexes only what changed, while any tool can also be run as a one-shot command-line call with compact or JSON output. Teams can commit a compressed graph snapshot beside the source so teammates index only their local differences.

Additional features include architecture summaries with functional clustering, persistent architecture decision records, documentation linked to the code it mentions, index coverage reporting, and a local browser interface for exploring source, call paths and architecture maps.
