Aryn for AI agents
Aryn is an AI platform for parsing and extracting structured data from unstructured documents, used by data teams to turn PDFs and files into queryable information 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.
What agents do in Aryn.
Extract structured data from a document
Partition a document into structured elements that are ready for downstream data processing steps.
Create a document set for a project
Create a docset to group a collection of related documents together for one project.
Confirm before deleting a docset
Deleting a docset removes every document inside it, so it should be confirmed first.
9 Aryn actions, graded by risk.
Every Aryn action is tagged read, write or destructive, so one policy covers the whole app and new actions inherit the right default.
read
4Look things up. Allowed by default.
- aryn.get_doc_setGet DocSet Metadata
- aryn.get_documentGet Document by ID
- aryn.list_async_tasksList Async Tasks
- aryn.get_document_binaryDownload Document Binary
write
4Create and change things. Allow, or ask the user first.
- aryn.create_docsetCreate DocSet
- aryn.generate_planGenerate plan
- aryn.partition_documentPartition Document
- aryn.submit_async_add_docSubmit Document for Async Add Doc
destructive
1Delete, cancel or archive. Ask first, or deny outright.
- aryn.delete_docsetDelete DocSet
Aryn in three steps.
- 01Your users connect ArynThey add their Aryn api key on Arc0 Connect, under your brand. It goes straight into the vault.
- 02You set the rulesReads run, writes like “create DocSet” can wait for the user, and “delete DocSet” can be denied outright.
- 03Any agent can actYour agent calls Aryn through the Arc0 SDK or MCP, and so can Claude, ChatGPT and Cursor. Every call lands on the audit log.
await arc0.policies.set('aryn', { read: 'allow', write: 'ask', // create_docset destructive: 'deny', // delete_docset }) # Claude Code: the same connection, one URL $ claude mcp add --transport http arc0 \ https://mcp.arc0.ai/u/u_8f2
How Aryn connects.
Users add their Aryn 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 Aryn connection serves your agent over MCP and your own backend over REST and the proxy, so a user connects once. How Arc0 handles credentials →
- AUTH
- API key
- CREDENTIALS
- Per-tenant encrypted vault
- MODEL SEES
- Results only, never credentials
- AUDIT LOG
- Every call, on every plan
Use Aryn from any agent.

Aryn and Arc0, answered.
Can I use Aryn with Claude, ChatGPT or Cursor?
Yes. Connect Aryn 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 Aryn actions you allow.
How do users connect Aryn?
Users add their Aryn 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.
Which Aryn actions can my agent take?
9 in total: 4 read, 4 write and 1 destructive, such as “create DocSet”. Your policies decide which of them each agent may call.
Can I stop my agent from deleting things in Aryn?
Yes. Actions like “delete DocSet” 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.
Can my own backend call Aryn too?
Yes. The same Aryn connection is available over REST and through the Arc0 proxy, so your product and your agent share one connection per user.
Plug Aryn into your agent.
Your users connect Aryn once, under your brand. Your agent gets 9 actions behind your policies, with every call on the record.
