MCP Memory is a code AI tool listed on Use AI Tools. An OKF-backed Model Context Protocol server that gives AI agents persistent long-term memory with SQLite FTS5 search. It exposes memory as a standard MCP resource, so clients that already speak MCP can read and write long-term context without a custom integration layer.

Q: What is MCP Memory best for?

MCP Memory is commonly used for Adding long-term memory to an existing MCP client, Self-hosters who prefer SQLite over a vector database, Agents that need keyword search rather than embeddings. It supports English.

🎯 Real-World Use Cases

Long-term agent memory

Let an agent write facts and preferences to disk once and recall them weeks later through the MCP interface.

SQLite FTS5 retrieval

Query stored memories with full-text search backed by SQLite FTS5, which keeps the deployment to a single file.

Shared memory across tools

Point several MCP-capable clients at the same server so the same memory store is available from each.

⚖️ Honest Review

✅ Pros

+Standard MCP interface, no bespoke client code
+SQLite keeps the storage footprint tiny
+Follows the published OKF memory format

⚠️ Cons

−Keyword search only, no semantic embeddings
−Single-node SQLite is not designed for team-scale concurrency
