ComPDF for AI agents

ComPDF converts, edits, and extracts data from PDFs through a cloud API, handling tasks like compressing, splitting, or parsing documents at scale. 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.

  3. 03Any agent can actYour agent calls ComPDF through the Arc0 SDK or MCP, and so can Claude, ChatGPT and Cursor. Every call lands on the audit log.

04 · AUTH AND DATA

How ComPDF connects.

Users add their ComPDF api key on Arc0 Connect. It is encrypted in the vault, never shown to the model, and each user can rotate or revoke it at any time.

The same ComPDF 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

ComPDF and Arc0, answered.

Q01

Can I use ComPDF with Claude, ChatGPT or Cursor?

Yes. Connect ComPDF 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 ComPDF actions you allow.

Q02

How do users connect ComPDF?

Users add their ComPDF api key on Arc0 Connect. It is encrypted in the vault, never shown to the model, and each user can rotate or revoke it at any time.

Q03

Which ComPDF actions can my agent take?

19 in total: 10 read, 7 write and 2 destructive, such as “add PDF Watermark”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in ComPDF?

Yes. Actions like “delete PDF Pages” are graded destructive. Set destructive actions to deny, or to ask so the user approves each one, and blocked calls still show up on the audit log.

Q05

Can my own backend call ComPDF too?

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