### Description (declared)

# codebase-mcp

A local MCP server that gives any AI agent or IDE a persistent, structured understanding of your codebase. It indexes your project once, stores everything in a local SQLite database, and answers structural questions instantly without the agent having to read any files.

---

## The problem it solves

Every time you start a new session in Claude Code, Cursor, Cline, or any other AI tool, the agent has to re-read your files to understand the codebase. On large projects this burns thousands of tokens just on orientation, and the agent still only sees a shallow surface. It cannot answer questions like "what calls this function", "what changed since yesterday", or "what decisions were made and why" without reading everything again.

codebase-mcp solves this by:

- Parsing your code once with tree-sitter (Python, TypeScript, JavaScript, Go, Rust, and 50+ more languages)
- Storing every function, class, method, import, and call site in a local database
- Keeping that database up to date incrementally (only changed files are re-parsed)
- Exposing a set of MCP tools so any agent can query the structure without reading files
- Persisting architectural decisions, notes, and session history across every agent and IDE you use

## How it is different from standard approaches

| | Standard approach | codebase-mcp |
|---|---|---|
| Codebase understanding | Agent reads files in context window | Pre-indexed, queried via tool calls |
| Cost per session | Hundreds to thousands of tokens on orientation | Near zero — index is already built |
| Call graph | Not available | Full caller/callee resolution with 3 strategies |
| Decisions and notes | Lost when context resets | Stored in database, searchable forever |
| Switching agents/IDEs | Start over from scratch | Export once, import anywhere |
| Multi-language | Depends on the agent | 50+ languages via tree-sitter |
| Incremental updates | Full re-read every time | SHA256-based, only changed files reparsed |
