Buffer for AI agents

Buffer schedules and publishes social media posts across connected channels, giving a marketing team one queue to plan and release content from. 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 Buffer.

01

Draft a post for review

Create a post draft for a channel and leave it pending review before it goes live.

02

Publish queued posts

Publish a batch of scheduled posts to their connected channels at the planned time.

03

Check what's already scheduled

List upcoming posts on a channel before adding new ones, to avoid double-booking a slot.

02 · ACTIONS

Buffer in three steps.

  1. 01Your users connect BufferThey sign in to Buffer on Arc0 Connect, under your brand, and approve the access you ask for.
  2. 02You set the rulesReads run, writes like “create Idea” can wait for the user, and “delete Post” can be denied outright.
  3. 03Any agent can actYour agent calls Buffer 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('buffer', {
  read: 'allow',
  write: 'ask',        // create_idea
  destructive: 'deny',  // delete_post
})

04 · AUTH AND DATA

How Buffer connects.

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

The same Buffer 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

Buffer and Arc0, answered.

Q01

Can I use Buffer with Claude, ChatGPT or Cursor?

Yes. Connect Buffer 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 Buffer actions you allow.

Q02

How do users connect Buffer?

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

Q03

Which Buffer actions can my agent take?

11 in total: 5 read, 4 write and 2 destructive, such as “create Idea”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in Buffer?

Yes. Actions like “delete Post” 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 Buffer too?

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