Synapse: Local Codebase Memory for Claude
koka786 · reddit · 2026-07-20
The author released an open-source project called Synapse: a locally run MCP server that gives Claude the ability to "instantly understand codebases."
It indexes the codebase locally and exposes two tools via MCP:
- recall: Semantic search
- context: Directly pulls full file contents
It is designed to be "100% local, no cloud, no API key required." The underlying tech relies on nomic-embed-text-v1.5 and LanceDB, and installation is lightweight: pip install synapse-mcp. The project is MIT-licensed and fully open-source on GitHub.
