Owl Protocol for AI agents
Owl Protocol is modular infrastructure for building Web3 applications, letting developers deploy contracts and manage blockchain projects without deep protocol expertise. Web3 teams use it to ship apps faster. 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 Owl Protocol.
Deploy a new NFT collection
Deploy an ERC721 collection contract for a project ready to mint tokens.
Check a project's configuration
Look up a project's details read-only before deciding what to deploy next.
Review all active projects
List projects in the workspace to confirm which ones are live before making changes.
3 Owl Protocol actions, graded by risk.
Every Owl Protocol action is tagged read, write or destructive, so one policy covers the whole app and new actions inherit the right default.
read
2Look things up. Allowed by default.
- owl_protocol.list_projectsList Projects
- owl_protocol.get_project_detailsGet Project Details
write
1Create and change things. Allow, or ask the user first.
- owl_protocol.deploy_collectionDeploy ERC721 Collection
destructive
0Delete, cancel or archive. Ask first, or deny outright.
- No destructive actions.
Owl Protocol in three steps.
- 01Your users connect Owl ProtocolThey add their Owl Protocol api key on Arc0 Connect, under your brand. It goes straight into the vault.
- 02You set the rulesReads run, and writes like “deploy ERC721 Collection” can wait for the user to approve.
- 03Any agent can actYour agent calls Owl Protocol through the Arc0 SDK or MCP, and so can Claude, ChatGPT and Cursor. Every call lands on the audit log.
await arc0.policies.set('owl_protocol', { read: 'allow', write: 'ask', // deploy_collection destructive: 'deny', }) # Claude Code: the same connection, one URL $ claude mcp add --transport http arc0 \ https://mcp.arc0.ai/u/u_8f2
How Owl Protocol connects.
Users add their Owl Protocol 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 Owl Protocol 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 Owl Protocol from any agent.

Owl Protocol and Arc0, answered.
Can I use Owl Protocol with Claude, ChatGPT or Cursor?
Yes. Connect Owl Protocol 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 Owl Protocol actions you allow.
How do users connect Owl Protocol?
Users add their Owl Protocol 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 Owl Protocol actions can my agent take?
3 in total: 2 read, 1 write and 0 destructive, such as “deploy ERC721 Collection”. Your policies decide which of them each agent may call.
Can I make my agent read-only in Owl Protocol?
Yes. Allow read actions and deny writes in the Owl Protocol policy. Your agent can still look things up, and any write it attempts is blocked and logged.
Can my own backend call Owl Protocol too?
Yes. The same Owl Protocol connection is available over REST and through the Arc0 proxy, so your product and your agent share one connection per user.
Plug Owl Protocol into your agent.
Your users connect Owl Protocol once, under your brand. Your agent gets 3 actions behind your policies, with every call on the record.
