Draftable for AI agents
Draftable is a document comparison API that highlights differences between versions of PDF, Word, and PowerPoint files, used by legal and operations teams reviewing contract redlines. 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 Draftable.
Check recent comparisons
List comparisons run on the account to find one already generated for a document pair.
Confirm a contract redline was run
Look up a comparison to confirm two contract versions were already checked for differences.
Read-only comparison history
Keep comparison listing read-only, since it only surfaces past results and never edits a document.
1 Draftable actions, graded by risk.
Every Draftable action is tagged read, write or destructive, so one policy covers the whole app and new actions inherit the right default.
read
1Look things up. Allowed by default.

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

Draftable and Arc0, answered.
Can I use Draftable with Claude, ChatGPT or Cursor?
Yes. Connect Draftable 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 Draftable actions you allow.
How do users connect Draftable?
Users add their Draftable 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 Draftable actions can my agent take?
1 in total: 1 read, 0 write and 0 destructive. Your policies decide which of them each agent may call.
Can I make my agent read-only in Draftable?
Yes. Allow read actions and deny writes in the Draftable policy. Your agent can still look things up, and any write it attempts is blocked and logged.
Can my own backend call Draftable too?
Yes. The same Draftable connection is available over REST and through the Arc0 proxy, so your product and your agent share one connection per user.
Plug Draftable into your agent.
Your users connect Draftable once, under your brand. Your agent gets 1 actions behind your policies, with every call on the record.
