Automatically detects git repositories to namespace and isolate memories per-repo, with cross-repo memory support and automatic repository indexing for semantic code search.
Supports repository-based memory management with automatic detection and indexing of GitHub repositories for context-aware semantic search and code navigation.
Provides hosted deployment storage backend using PostgreSQL with pgvector extension for vector embeddings, semantic search, and team sharing of memories.
Distributed as a Python package on PyPI for installation and deployment of the ContextFS memory layer.
Default local storage backend using SQLite with FTS5 for keyword search, memory storage, and session management.

Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@ContextFSsearch for recent decisions about database architecture"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.

# With uv (recommended)
uv pip install contextfs
# Run directly without installing
uvx contextfsQuick Start
# Initialize your repo for indexing
contextfs index init
# Save a memory
contextfs memory save "Use PostgreSQL for database" --type decision
# Search memories
contextfs memory search "database"
# Index your codebase for semantic search
contextfs index indexMCP Integration
Add to your AI tool's MCP config:
{
"mcpServers": {
"contextfs": {
"command": "uvx",
"args": ["contextfs"]
}
}
}Works with: Claude Code, Claude Desktop, Cursor, VS Code, and any MCP-compatible client.
See tool-specific setup guides for detailed instructions.
