[![PyPI - Version](https://img.shields.io/pypi/v/chroma-mcp-server?color=blue)](https://pypi.org/project/chroma-mcp-server)

A Model Context Protocol (MCP) server integration for [Chroma](https://www.trychroma.com/), the open-source embedding database.

## Overview

Chroma MCP Server creates a persistent, searchable "working memory" for AI-assisted development:

- **Automated Context Recall:** AI assistants can query relevant information from past sessions
- **Developer-Managed Persistence:** Store key decisions and insights in ChromaDB via MCP
- **Second Brain Integration:** Integrates with IDE workflows to create a unified knowledge hub

Key features:

- **Automated Codebase Indexing:** Track and index code changes
- **Automated Chat Logging:** Log AI interactions with enhanced context capture (code diffs, tool sequences)
- **Bidirectional Linking:** Connect discussions to code changes for tracing feature evolution
- **Semantic Code Chunking:** Preserve logical code structures for more meaningful context retrieval
- **Working Memory Tools:** MCP commands for capturing and retrieving development context
- **Validation System:** Evidence-based validation for code changes and learning promotions
- **Automated Test-Driven Learning:** Fully automated workflow from test failure to verified fix and learning promotion. See the [Pytest Plugin Usage Guide](docs/integration/pytest_plugin_usage.md) to integrate this into your projects.

See the [Getting Started with your Second Brain guide](docs/getting_started_second_brain.md) for more details.
