MarcoPolo for AI agents

MarcoPolo lets agents query and correlate data across databases, warehouses, cloud storage, and SaaS applications from one place instead of switching tools. Connect it once through Arc0, and your agent, or Claude, ChatGPT and Cursor, can use it through one MCP endpoint, limited to what each user approved.

04 · AUTH AND DATA

How MarcoPolo connects.

MarcoPolo runs its own MCP server behind OAuth. Arc0 registers the client, users approve access on Arc0 Connect, and your agent reaches MarcoPolo through the same endpoint, policies and audit log as every other app.

The same MarcoPolo connection serves your agent over MCP and your own backend over REST and the proxy, so a user connects once. How Arc0 handles credentials →

07 · FAQ

MarcoPolo and Arc0, answered.

Q01

Can I use MarcoPolo with Claude, ChatGPT or Cursor?

Yes. Connect MarcoPolo to Arc0 once, then add your Arc0 MCP URL to Claude, ChatGPT, Cursor, Claude Code or any other remote-MCP client. Each assistant only gets the MarcoPolo actions you allow.

Q02

How do users connect MarcoPolo?

MarcoPolo runs its own MCP server behind OAuth. Arc0 registers the client, users approve access on Arc0 Connect, and your agent reaches MarcoPolo through the same endpoint, policies and audit log as every other app.

Q03

Which MarcoPolo actions can my agent take?

5 in total: 0 read, 5 write and 0 destructive, such as “data query”. Your policies decide which of them each agent may call.

Q04

Can I make my agent read-only in MarcoPolo?

Yes. Allow read actions and deny writes in the MarcoPolo policy. Your agent can still look things up, and any write it attempts is blocked and logged.

Q05

Can my own backend call MarcoPolo too?

Yes. The same MarcoPolo connection is available over REST and through the Arc0 proxy, so your product and your agent share one connection per user.
