YourMemory: MCP server, setup and security

What YourMemory does

According to its repository: “Persistent agent memory with Ebbinghaus-style decay, hybrid BM25/vector retrieval, entity graph for multi-hop reasoning, auto-pruning and a browser dashboard.”

An MCP server gives an AI agent extra tools it calls during the conversation: the agent reads their description, decides to use them and gets the result back. YourMemory is listed under Memory and knowledge, a category of 250 servers in the directory, where it ranks #43 by stars.

Topics declared by the repository: ai-agents, claude, ebbinghaus, llm-memory, memory, pgvector.

Installing and connecting YourMemory

Distribution modes declared in the official MCP registry:

• PyPI package (Python, started with uvx or pip)

Like any MCP server, you declare it in your client's configuration (Claude Desktop, Claude Code, Cursor, VS Code, Codex…): a name, the command that starts it or its URL, and any environment variables. The client then starts it and lists its tools. Project language: Python. Listed systems: macOS, Windows, Linux.

Security: what to check

An MCP server runs code with the rights you give it, and the model reads its tool descriptions: a malicious or compromised server can hijack the agent. Read the code, or pick a maintained and widely used server, before connecting it.

Points found for YourMemory:

• No licence: without a licence the code is not legally reusable, even if it is public. Avoid it in a company setting without the author's agreement.

Good practice: grant only the rights needed (least privilege), require human approval for irreversible actions, and run the AI agent security check.

Project activity and maintenance

Created on March 2, 2026, the sachitrafa/YourMemory repository has 270 stars and 21 forks, with 1 open issues. It has more stars than 82% of the servers in the directory. Last change 1 month ago. Version published in the registry: 1.4.18 (May 2, 2026).

Stars measure attention, not quality: a recent, heavily promoted project can collect them fast, while a useful but niche server will have few.
