Codebase Context Mcp
Gives Claude indexing and search across your codebase without requiring native binaries. Ships with WASM tree-sitter so it installs cleanly on ARM64 (Raspberry Pi, Apple Silicon, Graviton) and x86_64 alike. Exposes five tools: index_codebase to parse a directory into symbols and chunks stored as JSON, search_symbols for finding functions and classes by name, search_code for BM25 full-text search, get_file_outline for file structure with line numbers, and get_project_summary for tech stack overview. Supports TypeScript, JavaScript, Python, C#, and a handful of other languages. Respects gitignore and caps files at 512KB. Useful when you want symbol navigation and code search without fighting npm install failures on non-x86 platforms.

codebase-context-mcp
MCP server for codebase indexing and search that works on every platform — including ARM64 devices like Raspberry Pi and Apple Silicon where most alternatives fail.
The Problem
Popular codebase-indexing MCP servers like @zilliz/claude-context-mcp depend on native C++ bindings (tree-sitter, faiss-node) that ship pre-built binaries only for x86_64. If you're on ARM64 — a Raspberry Pi, Apple Silicon Mac, AWS Graviton, or any other arm64 host — npm install fails with missing prebuilts and no fallback. There's no workaround short of cross-compiling the native modules yourself.
The Solution
This package replaces every native dependency with a WASM equivalent. The tree-sitter parser runs as WebAssembly, search uses a pure-JS BM25 implementation, and the index is stored as plain JSON. Zero native bindings means npm install succeeds on the first try on any architecture: ARM64, x86_64, macOS, Linux, Windows.
Drop-in compatible — provides the same core tools (index, search, outline, summary) via the standard MCP stdio transport.
