Add YourMemory — Ebbinghaus-based persistent memory MCP server

[sachitrafa]

Summary

Adds YourMemory to the community servers list.

YourMemory is a persistent memory MCP server for Claude that implements the Ebbinghaus Forgetting Curve — memories decay with time, strengthen on recall, and are ranked by relevance × freshness.

How it works:

• recall_memory(query) — surfaces relevant context at the start of every task
• store_memory(content, importance) — Claude assigns importance 0.0–1.0
• update_memory(id, new_content, importance) — merge or override existing memories

Decay formula:

strength = importance × e^(−λ × days) × (1 + recall_count × 0.2)

High-importance memories decay slower. Retrieval score = cosine_similarity × strength.

Stack: PostgreSQL + pgvector, Ollama (local embeddings), FastAPI, MCP stdio transport. Fully local, no cloud required.

Thanks for contributing to the MCP servers repo!

We've retired the third-party server list from the README in favor of the MCP Registry — see #3950 for context. The Official Integrations and Community Servers sections no longer exist in the README, so this PR no longer has a target.

Going forward, please publish your server to the MCP Registry using the quickstart guide:
https://github.com/modelcontextprotocol/registry/blob/main/docs/modelcontextprotocol-io/quickstart.mdx

That's where server discovery now happens. Thanks for building on MCP!

Note: I'm working through the backlog with help from Claude Code to give everyone a prompt response.
