Connect Gemini CLI

Gemini CLI talks to Mimir over the Model Context Protocol at https://mimir.johansen.foo/mcp. The token is an API key from Settings → API keys in the Mimir app; export it as MIMIR_TOKEN before starting the agent.

1. Add the server

File: ~/.gemini/settings.json

json

{
  "mcpServers": {
    "mimir": {
      "httpUrl": "https://mimir.johansen.foo/mcp",
      "headers": {
        "Authorization": "Bearer ${MIMIR_TOKEN}"
      }
    }
  }
}

2. Verify

Ask the agent to run memory_tree. It should list the projects your token can see, or nothing at all on a fresh install — either answer proves the connection works.

3. Tell it how to behave

Paste this into the agent's rules or instructions file, once per machine.

text

You have a long-term memory store called Mimir.
At the start of a session, call memory_digest with the current repository to load what is already known.
Before answering a question about this project's conventions, call memory_search with a path_prefix (for example "conventions").
When you learn something durable — a decision, a convention, a gotcha — call memory_write with a path that says where it belongs.
Do not store secrets, tokens or customer data.

Notes

Gemini CLI uses httpUrl for streamable HTTP servers; url is for stdio commands.
Put the instruction block below in ~/.gemini/GEMINI.md so it is loaded for every session.
