MarcoPolo is a Codex plugin, developed by Immersa, Inc., that spins up a secure container where Codex can work with a user's actual data, according to the plugin's manifest. It connects to databases, APIs, S3, lakehouses, CRMs, Jira, logs, and other systems using scoped credentials that are never exposed to the model. Inside the container, Codex has access to DuckDB, Python, a shell, and additional tools to explore, query, transform, and analyze data, and the workspace persists so users can build on prior work. The marcopolo.dev homepage describes a broader product line—Sandbox, Cost Plane, and Connections—positioned as a governed workspace for running enterprise AI, featuring per-user credential scoping, audit logging to a SIEM, and portability across AI models such as Claude, ChatGPT, Cursor, and Copilot. Specific pricing, technical limitations of the plugin itself, and version details beyond "1.0.3" are unknown from the provided sources.

Overview

MarcoPolo (marcopolo.dev), made by Immersa, Inc., is presented on its homepage as a governed workspace that lets enterprise teams connect once to systems such as data warehouses, databases, SaaS tools, and storage, and then give AI models access to that context under IT-controlled, scoped credentials, audit logging, and per-user sandboxed containers.
