# Sigil MCP Server [![Version](https://img.shields.io/badge/version-1.0.1-blue)](CHANGELOG.md) [![Tests](https://img.shields.io/badge/tests-408%20passed%20(41s)-brightgreen)](tests) [![Coverage](https://img.shields.io/badge/coverage-76%25-yellowgreen)](coverage.xml) [![Changelog](https://img.shields.io/badge/changelog-CHANGELOG.md-blue)](CHANGELOG.md)

A Model Context Protocol (MCP) server that provides IDE-like code navigation and search for local repositories. Gives AI assistants like ChatGPT powerful code exploration capabilities including symbol search, trigram indexing, and semantic navigation.

## Quickstart

See `docs/QUICKSTART.md` for the fastest path to a working config and the most common knobs (index path, repos, embeddings on/off, admin settings).

## Features

**Hybrid Code Search**
- Fast text search using trigram indexing (inspired by GitHub's Blackbird)
- Trigram store uses RocksDB via `rocksdict` (install with `pip install -e .[trigrams-rocksdict]`); SQLite fallback is removed.
- Symbol-based search for functions, classes, methods, and variables
- Semantic code search with vector embeddings backed by LanceDB (ANN queries, per-repo vector stores)
- File structure view showing code outlines
- Automatic index updates with file watching (optional)

**Production Ready**
- Thread-safe concurrent access (SQLite WAL mode + RLock serialization)
- File watcher, HTTP handlers, and vector indexing run safely in parallel
- No "database is locked" errors from concurrent operations
- Admin API for operational management (index rebuilds, stats, logs)
- Comprehensive request/response logging with header redaction

**Enterprise Security**
- OAuth 2.0 authentication with PKCE support for remote access
- Local connection bypass (no auth needed for localhost)
- API key fall…
