Synapse MCP Overview

myelixlabs/synapse-mcp MCP server turns a codebase into a persistent, local AST knowledge graph for coding agents. A long-running BEAM daemon watches file changes, incrementally re-indexes modified files, and detects Git diffs. Its MCP tools support structural search, graph traversal, debugging, change review, test analysis, repository management, and validated atomic writes. Reach for it when an agent needs codebase-wide context without sending source code to a cloud service.

Primary Use Cases for Synapse MCP:

Navigate unfamiliar code through caller and callee relationships
Review refactoring impact before changing files
Trace stack errors to likely AST root causes
Identify test coverage gaps and affected tests
