MCP memory server for AI coding assistants. Windows Service, ONNX embeddings, SQLite vector search.
A zero-dependency MCP memory server for Windows that gives AI coding assistants a shared, persistent memory layer with semantic search.
AI coding assistants like Claude Code are stateless—each session starts fresh, with no persistent memory of your prior context, decisions, or discoveries. ContextBridge solves this by running as a background Windows Service that all your AI tools connect to. It stores memories persistently, searchable by meaning (not keywords), so context accumulates across sessions and across different tools simultaneously.

| Tool | What it does |
|---|---|
| project | <repo-name> — scope memories to a project |
| type | decision — architectural or technology choices |
| content | the session summary (free-form text) |
| ttl_days | how many days to keep the handoff before auto-expiry (default: 7) |
| memory_write | Store a single memory with automatic semantic embedding and optional tags |
| memory_batch_write | Store multiple related memories atomically (efficient end-of-session extraction) |
| memory_search | Semantic search — natural language query, returns nearest-neighbor results |
| memory_list | Paginated list of all memories with optional tag filters |
| memory_update | Update a memory's content (re-embedded automatically) |
| memory_delete | Delete a memory by ID |
| memory_status | Service health check, record count, model info |
| handoff_write | Capture session state — what you're working on, decisions made, next steps |
| handoff_list | Retrieve active handoffs, optionally filtered by project |
| handoff_acknowledge | Remove a handoff after processing it (permanent deletion) |
