Plaid for AI agents
Plaid gives authorized teams read-only production diagnostics for Items, Link conversion, and API usage. Engineering and support teams use it to debug integration issues without support tickets. 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 Plaid.
Debug a failing Item
Pull diagnostics for a Plaid Item to see why a bank connection is failing.
Check Link conversion metrics
Look up Link conversion analytics read-only to spot where users drop off during connection.
Check API usage volumes
Review usage metrics read-only to track API call volume against plan limits.
5 Plaid actions, graded by risk.

read
0Look things up. Allowed by default.
- No read actions.
write
5Create and change things. Allow, or ask the user first.

Plaid in three steps.
- 01Your users connect PlaidThey sign in to Plaid on Arc0 Connect, under your brand, and approve the access you ask for.
- 02You set the rulesReads run, and writes like “plaid debug item” can wait for the user to approve.
- 03Any agent can actYour agent calls Plaid through the Arc0 SDK or MCP, and so can Claude, ChatGPT and Cursor. Every call lands on the audit log.
await arc0.policies.set('plaid', { read: 'allow', write: 'ask', // plaid_debug_item destructive: 'deny', }) # Claude Code: the same connection, one URL $ claude mcp add --transport http arc0 \ https://mcp.arc0.ai/u/u_8f2
How Plaid connects.
Plaid runs its own MCP server behind OAuth. Arc0 registers the client, users approve access on Arc0 Connect, and your agent reaches Plaid through the same endpoint, policies and audit log as every other app.
The same Plaid 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
- OAuth 2.0 (MCP)
- CREDENTIALS
- Per-tenant encrypted vault
- MODEL SEES
- Results only, never credentials
- AUDIT LOG
- Every call, on every plan
Use Plaid from any agent.

Plaid and Arc0, answered.
Can I use Plaid with Claude, ChatGPT or Cursor?
Yes. Connect Plaid 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 Plaid actions you allow.
How do users connect Plaid?
Plaid runs its own MCP server behind OAuth. Arc0 registers the client, users approve access on Arc0 Connect, and your agent reaches Plaid through the same endpoint, policies and audit log as every other app.
Which Plaid actions can my agent take?
5 in total: 0 read, 5 write and 0 destructive, such as “plaid debug item”. Your policies decide which of them each agent may call.
Can I make my agent read-only in Plaid?
Yes. Allow read actions and deny writes in the Plaid policy. Your agent can still look things up, and any write it attempts is blocked and logged.
Can my own backend call Plaid too?
Yes. The same Plaid connection is available over REST and through the Arc0 proxy, so your product and your agent share one connection per user.
Plug Plaid into your agent.
Your users connect Plaid once, under your brand. Your agent gets 5 actions behind your policies, with every call on the record.
