Serply for AI agents
Serply is a search API returning real-time results from Google, Bing, and other engines, including image, maps, jobs, and scholar search. Developers use it to add search data to their apps. 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 Serply.
Run an image search
Pull image search results for a query to source visuals or verify a product photo.
Look up a business on maps
Run a maps search to find a business's location, hours, or rating before referencing it.
Pull academic citations
Run a scholar search to find papers or citations relevant to a research question.
3 Serply actions, graded by risk.
Every Serply action is tagged read, write or destructive, so one policy covers the whole app and new actions inherit the right default.
read
0Look things up. Allowed by default.
- No read actions.
write
3Create and change things. Allow, or ask the user first.
- serply.perform_maps_searchPerform Maps Search
- serply.perform_image_searchPerform Image Search
- serply.perform_scholar_searchPerform Scholar Search
destructive
0Delete, cancel or archive. Ask first, or deny outright.
- No destructive actions.
Serply in three steps.
- 01Your users connect SerplyThey add their Serply api key on Arc0 Connect, under your brand. It goes straight into the vault.
- 02You set the rulesReads run, and writes like “perform Maps Search” can wait for the user to approve.
- 03Any agent can actYour agent calls Serply through the Arc0 SDK or MCP, and so can Claude, ChatGPT and Cursor. Every call lands on the audit log.
await arc0.policies.set('serply', { read: 'allow', write: 'ask', // perform_maps_search destructive: 'deny', }) # Claude Code: the same connection, one URL $ claude mcp add --transport http arc0 \ https://mcp.arc0.ai/u/u_8f2
How Serply connects.
Users add their Serply 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 Serply 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 Serply from any agent.

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