ActiveMerge for AI agents

ActiveMerge automates document and image generation from templates, including merging, e-signatures and file storage. Operations teams use it to produce contracts, letters and reports 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 ActiveMerge.

01

Look up how many generation credits are left on the account before starting a large merge job.

02

Generate a document from a template

Fill a document template with data to produce a contract, invoice or letter ready for review.

Store a batch of newly generated documents so they can be retrieved or shared later.

02 · ACTIONS

13 ActiveMerge actions, graded by risk.

Every ActiveMerge action is tagged read, write or destructive, so one policy covers the whole app and new actions inherit the right default.

03 · HOW IT WORKS

ActiveMerge in three steps.

  1. 01Your users connect ActiveMergeThey add their ActiveMerge api key on Arc0 Connect, under your brand. It goes straight into the vault.
  2. 02You set the rulesReads run, and writes like “generate Images” can wait for the user to approve.
  3. 03Any agent can actYour agent calls ActiveMerge through the Arc0 SDK or MCP, and so can Claude, ChatGPT and Cursor. Every call lands on the audit log.
POLICY.TS
await arc0.policies.set('activemerge', {
  read: 'allow',
  write: 'ask',        // generate_images
  destructive: 'deny',  
})

04 · AUTH AND DATA

How ActiveMerge connects.

Users add their ActiveMerge 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 ActiveMerge 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

ActiveMerge and Arc0, answered.

Q01

Can I use ActiveMerge with Claude, ChatGPT or Cursor?

Yes. Connect ActiveMerge 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 ActiveMerge actions you allow.

Q02

How do users connect ActiveMerge?

Users add their ActiveMerge 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 ActiveMerge actions can my agent take?

13 in total: 9 read, 4 write and 0 destructive, such as “generate Images”. Your policies decide which of them each agent may call.

Q04

Can I make my agent read-only in ActiveMerge?

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

Q05

Can my own backend call ActiveMerge too?

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