FAQ from OpenMemory MCP Troubleshooting Guide

What does “Server transport closed unexpectedly” mean?

It means the MCP client lost connection to the OpenMemory server, usually due to a missing API key, Docker not running, or an incorrect configuration.

How do I verify the OpenMemory services are running?

Run docker ps | grep openmemory and check that containers for API, Postgres, and Qdrant are present. Then test curl http://localhost:8765/health and curl http://localhost:8765/docs.

What are the memory formatting guidelines?

Store memories in plain text without markdown, lists, or line breaks. Keep them concise, natural, and focused on a single topic. For example: “Ian has 18 MCP servers installed…” (good) vs. formatted lists (poor).

How do I configure Claude Desktop to use OpenMemory?

Edit your Claude Desktop configuration file (macOS: ~/Library/Application Support/Claude/claude_desktop_config.json) and add an openmemory entry under mcpServers with npx @modelcontextprotocol/server-sse http://localhost:8765/mcp/claude/sse/ian.

What should I do if port 8765 is already in use?

Use lsof -i :8765 to find the process and kill it, or change the OpenMemory port and update the configuration accordingly.
