Ragie for AI agents
Ragie is a fully managed retrieval-augmented generation service for developers building AI features on their own documents. Product teams use it to add search and grounded answers without building RAG infrastructure. 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 Ragie.
Add a document to a partition
Ingest a new document so it becomes searchable for retrieval-augmented generation.
Retrieve relevant document chunks
Pull the most relevant chunks for a query to ground an AI-generated answer.
Delete a document with approval
Remove a document from the index only after confirming it should no longer be retrievable.
31 Ragie actions, graded by risk.
Every Ragie action is tagged read, write or destructive, so one policy covers the whole app and new actions inherit the right default.

Ragie in three steps.
- 01Your users connect RagieThey add their Ragie api key on Arc0 Connect, under your brand. It goes straight into the vault.
- 02You set the rulesReads run, writes like “create Document” can wait for the user, and “delete Document” can be denied outright.
- 03Any agent can actYour agent calls Ragie through the Arc0 SDK or MCP, and so can Claude, ChatGPT and Cursor. Every call lands on the audit log.
await arc0.policies.set('ragie', { read: 'allow', write: 'ask', // create_document destructive: 'deny', // delete_document }) # Claude Code: the same connection, one URL $ claude mcp add --transport http arc0 \ https://mcp.arc0.ai/u/u_8f2
How Ragie connects.
Users add their Ragie 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 Ragie 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 Ragie from any agent.

Ragie and Arc0, answered.
Can I use Ragie with Claude, ChatGPT or Cursor?
Yes. Connect Ragie 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 Ragie actions you allow.
How do users connect Ragie?
Users add their Ragie 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 Ragie actions can my agent take?
31 in total: 16 read, 12 write and 3 destructive, such as “create Document”. Your policies decide which of them each agent may call.
Can I stop my agent from deleting things in Ragie?
Yes. Actions like “delete Document” 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 Ragie too?
Yes. The same Ragie connection is available over REST and through the Arc0 proxy, so your product and your agent share one connection per user.
Plug Ragie into your agent.
Your users connect Ragie once, under your brand. Your agent gets 31 actions behind your policies, with every call on the record.
