aptu-coder is an MCP server that analyzes codebases using tree-sitter to provide directory trees, symbol definitions, imports, and call graphs without reading raw files. It runs locally over stdio and supports multiple languages including Rust, Python, Go, Java, TypeScript, Fortran, JavaScript, C/C++, and C#.
From the registry: MCP server for code structure analysis using tree-sitter.
Install & configure
Prerequisites
- optionalInstall aptu-coderInstall the aptu-coder binary using the simplest portable published method shown in the README.
$ cargo binstall aptu-coder - optionalAlternative install via HomebrewOn macOS or Linux, you can install aptu-coder from the project's Homebrew tap instead of using cargo-binstall.
$ brew install clouatre-labs/tap/aptu-coder - optionalAlternative install via cargo installInstall from crates.io using Cargo if you already have a Rust toolchain.
$ cargo install aptu-coder
Install in your client
Paste into the AI you're chatting with — it will figure out the rest
Please install the `aptu-coder` MCP server into my current AI client (that's you).
Optional prerequisites:
- Install aptu-coder — Install the aptu-coder binary using the simplest portable published method shown in the README. Run: `cargo binstall aptu-coder`
- Alternative install via Homebrew — On macOS or Linux, you can install aptu-coder from the project's Homebrew tap instead of using cargo-binstall. Run: `brew install clouatre-labs/tap/aptu-coder`
- Alternative install via cargo install — Install from crates.io using Cargo if you already have a Rust toolchain. Run: `cargo install aptu-coder`
Canonical MCP server config (stdio transport):
- command: `aptu-coder`
- args: []
- optional environment variables:
- `CODE_ANALYZE_FILE_CACHE_CAPACITY`: Maximum number of file-analysis results held in the in-process LRU cache. Increase for large repositories where many files are queried repeatedly. (example: `<file-cache-capacity>`)
- `CODE_ANALYZE_DIR_CACHE_CAPACITY`: Maximum number of directory-analysis results held in the in-process LRU cache. (example: `<dir-cache-capacity>`)
- `DISABLE_PROMPT_CACHING`: Set to 1 to disable prompt caching; recommended for single-pass subagent sessions. (example: `<1-or-unset>`)
- `DISABLE_PROMPT_CACHING_HAIKU`: Set to 1 to disable prompt caching for Haiku-specific pipelines only. (example: `<1-or-unset>`)
Note: The README explicitly recommends stdio because the server runs locally against files on disk. No environment variables are required for basic operation.
Add this MCP server to my current client's config in the correct format for you. If you need secrets or credentials I haven't provided, ASK me — do not invent values or leave raw placeholders. After adding it, tell me how to verify the server is connected.Note: The README explicitly recommends stdio because the server runs locally against files on disk.
