Linguapop for AI agents
Linguapop is a language placement testing platform schools use to assess student proficiency in English, German, Spanish, Italian, and French. 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.

Linguapop in three steps.
- 01Your users connect LinguapopThey add their Linguapop 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 Linguapop through the Arc0 SDK or MCP, and so can Claude, ChatGPT and Cursor. Every call lands on the audit log.
await arc0.policies.set('linguapop', { 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 Linguapop connects.
Users add their Linguapop 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 Linguapop 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 Linguapop from any agent.

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