Endpoint and raw config for custom clients. Claude on your phone uses OAuth: add the endpoint as a custom connector at claude.ai/customize/connectors, sign in to cosmos when prompted, then enable the connector in chat (+ → Connectors). Cursor and Claude Desktop still use pmk_ keys via the install script.

Import memory
Pull what claude, chatgpt, gemini, or any other assistant has stored about you into your cosmos graph. One generic prompt, paste the result back.
I'm moving to another service and need to export my data. List every memory you have stored about me, as well as any context you've learned about me from past conversations. Output everything in a single code block so I can easily copy it. Format each entry as: [date saved, if available] - memory content. Make sure to cover all of the following, preserve my words verbatim where possible. Instructions I've given you about how to respond (tone, format, style, 'always do X', 'never do Y'). Personal details: name, location, job, family, interests. Projects, goals, and recurring topics. Tools, languages, and frameworks I use. Preferences and corrections I've made to your behavior. Any other stored context not covered above. Do not summarize, group, or omit any entries. After the code block, confirm whether that is the complete set or if any remain.
