List the idea workflow groups in a Buffer organization so an agent can discover group IDs for filtering or idea creation.

List Ideas

List content ideas in a Buffer organization, optionally filtering by explicit idea groups or grouped versus ungrouped workflow membership.

List Posts

List and filter posts in a Buffer organization without requesting OAuth-inaccessible analytics fields.

List Post Templates

Connect to AI Agent

typescript
import { openai } from '@ai-sdk/openai';
import { experimental_createMCPClient as createMCPClient } from '@ai-sdk/mcp';
import { generateText } from 'ai';

const client = await createMCPClient({
  transport: {
    type: 'http',
    url: session.mcp.url,
    headers: {
      'x-api-key': 'your-composio-api-key',
    },
  },
});

const tools = await client.tools();
const { text } = await generateText({
  model: openai('gpt-4o'),
  tools,
  messages: [{
    role: 'user',
    content: 'Schedule a Buffer post for tomorrow at 9 AM saying: New product demo is live today'

FAQ

Frequently asked questions

Buffer requires connections to go through your own OAuth app. You register it once with Buffer, add its client ID and secret in the Composio dashboard, and from then on everyone connects by signing in to Buffer as usual. Composio handles the rest of the flow and the token refresh.

Yes! Composio's Tool Router enables agents to use multiple toolkits. Learn more.

Yes. Composio is SOC 2 Type II compliant and is built to keep your Buffer connection and credentials secure. OAuth tokens and API keys are encrypted, and sensitive customer data is protected at rest and in transit.

Composio also undergoes independent security testing and continuously monitors its systems for security threats. You can review the latest reports and policies in the Composio Trust Center.

Composio maintains and updates all toolkit integrations automatically, so your agents always work with the latest API versions.

When you connect a Buffer account through Composio, every action runs under that account, so anything the agent creates, sends, or changes shows up in Buffer as done by you. Keep an approval step in your prompt for actions with side effects, such as sending or deleting, and have the agent draft first.

Exactly the ones Buffer lists on its consent screen when you connect. Review that screen before approving. If you connect a work account, your Buffer administrator may need to approve the app first, and you can revoke the access inside Buffer whenever you want.

Yes. Composio supports multiple connected accounts for the same app, and that works in Claude, ChatGPT, or any other assistant you connect through Composio. Give each Buffer connection a name such as work or personal, and the assistant uses the one you mention in the request. Each account keeps its own credentials and nothing is merged.

Composio refreshes Buffer tokens automatically, so day to day you do nothing. If you revoke access inside Buffer, or Buffer invalidates the session, the connection shows as expired in Composio and the agent stops acting on that account until you reconnect it, which is a single sign-in.

Composio's free plan includes 100,000 tool calls per month with no credit card, which covers most personal Buffer use. Paid plans add higher limits and team features. Your Buffer plan and its API limits still apply as usual.

Built-in connectors usually give one AI access to a limited set of apps. Many people use Composio because it lets their AI connect to more apps than it normally supports, or connect to multiple accounts for the same app (e.g. connect Claude to multiple Buffer accounts).

With Composio, you connect Buffer once and then use it across different AI assistants without setting it up separately in each one. Connect your apps to Composio once, then connect Composio to whichever AI you use, whether that's Claude, ChatGPT, Hermes, or your own custom assistant.
