Set up or diagnose the Marina plugin's memory and optional world connections in Codex. Use when installing Marina or when its tools cannot connect or authenticate.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
Read the installed plugin's `.mcp.json` for its configured connections, URLs and credential file paths. A build may include `marina_memory`, `marina_world`, or both. The bundled [setup guide](../../README.md) explains provisioning, installation and rebuilding. Check the configured Bun executable and credential file exist without displaying secrets. Credentials remain outside the plugin; a memory credential has `token` and `spaceId`, while a world transport credential has `token`. Do not ask users to paste tokens into the chat. Installing the plugin does not start Marina or provision credentials. Use an existing service when supplied; otherwise follow the guide to initialize a local memory service when requested. Memory and world listeners need separate ports when running as separate services. Discover the actual tools for the selected connection. On the dedicated memory connection, call `memory_service` with `operation:"me"`, then `operation:"spaces"`, and confirm the intended scope. Call `memory_retrieve` with a relevant task to check reading; an empty result is normal for a new space. Inspect `isError` and `structuredContent.ok` before reporting success. …

How to install
mdr add h2oai/marina/marina-setup@sha256:bcc924369ec70a07The line at the top of this page pins the label git:20261104.df1caa8, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
