Memra MCP Server

Give Claude Code, Cursor, and Windsurf persistent memory across chat sessions.

The problem it solves

AI coding assistants forget everything when the context window fills. Memra lets you save your session before it's lost, then instantly resume in a new chat with full context — no re-explaining your codebase, decisions, or preferences.

Install

npm install -g @memra/mcp-server

⚠️ Important: Use an MCP key (mk_mcp_...), not a Memory API key (mk_mem_...).
Go to Dashboard → MCP Keys tab to create one.

Get an API key

Visit memra-rho.vercel.app/dashboard/keys — free account, no credit card required.
On the keys page, switch to the MCP Keys tab and create a key starting with mk_mcp_.

Troubleshooting

Key not found

❌ Memra API Key Missing

Make sure MEMRA_API_KEY is set in your MCP config's env block, not as a shell variable.

Wrong key type

🔑 Wrong Key Type

You're using a Memory API key (mk_mem_...) instead of an MCP key (mk_mcp_...). Create an MCP key at memra-rho.vercel.app/dashboard/keys.
