Stack Exchange for AI agents

Stack Exchange is a network of question-and-answer communities, like Stack Overflow, where people ask, answer, and vote on questions across many topics. 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.

03 · HOW IT WORKS

Stack Exchange in three steps.

  1. 01Your users connect Stack ExchangeThey sign in to Stack Exchange on Arc0 Connect, under your brand, and approve the access you ask for.
  2. 02You set the rulesReads run, writes like “create Filter” can wait for the user, and “get My Merge History” can be denied outright.
  3. 03Any agent can actYour agent calls Stack Exchange 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('stack_exchange', {
  read: 'allow',
  write: 'ask',        // create_filter
  destructive: 'deny',  // get_my_merge_history
})

# Claude Code: the same connection, one URL
$ claude mcp add --transport http arc0 \

04 · AUTH AND DATA

How Stack Exchange connects.

Users sign in to Stack Exchange on Arc0 Connect and approve the scopes you request. Build with Arc0’s Stack Exchange OAuth app, or bring your own so the Stack Exchange consent screen names you. Tokens refresh automatically, and you can export them whenever you want.

The same Stack Exchange 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

Stack Exchange and Arc0, answered.

Q01

Can I use Stack Exchange with Claude, ChatGPT or Cursor?

Yes. Connect Stack Exchange 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 Stack Exchange actions you allow.

Q02

How do users connect Stack Exchange?

Users sign in to Stack Exchange on Arc0 Connect and approve the scopes you request. Build with Arc0’s Stack Exchange OAuth app, or bring your own so the Stack Exchange consent screen names you. Tokens refresh automatically, and you can export them whenever you want.

Q03

Which Stack Exchange actions can my agent take?

121 in total: 116 read, 2 write and 3 destructive, such as “create Filter”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in Stack Exchange?

Yes. Actions like “get My Merge History” are graded destructive. Set destructive actions to deny, or to ask so the user approves each one, and blocked calls still show up on the audit log.

Q05

Can my own backend call Stack Exchange too?

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