Buffer + Meta Muse
Manage Buffer (social media scheduling: organizations, channels, posts, ideas) from any AI agent via Buffer's GraphQL API. 9 tools, API key.
Prerequisites
See the full setup instructions baked into the connector (visible in the in-app store when you select the connector). The required environment variables for this connector are:
BUFFER_ACCESS_TOKEN
Step 1 — Get credentials
This connector wraps Buffer's public GraphQL API at https://api.buffer.com (docs: https://developers.buffer.com). It replaces the legacy api.bufferapp.com REST API; Buffer's API is available on every plan, including Free.
Setup:
- Sign in to Buffer and open Settings → API (https://publish.buffer.com/settings/api).
- Click Generate API Key (Personal Access tab). Free accounts can hold one key, paid plans up to five.
- Paste the key into
BUFFER_ACCESS_TOKEN. It is sent asAuthorization: Bearer <key>and acts as your own account: every organization and channel you can see in Buffer, with no per-organization scoping.
…(continued in the in-app connector instructions)
Step 2 — Install the adapter
curl -fsSL https://raw.githubusercontent.com/HelpCode-ai/anythingmcp/main/docker-compose.quickstart.yml -o docker-compose.yml
printf 'JWT_SECRET=%s\nENCRYPTION_KEY=%s\n' "$(openssl rand -hex 32)" "$(openssl rand -hex 32)" > .env
docker compose up -d
Step 3 — Add the connector in Muse
Your server URL: in AnythingMCP, open MCP Servers → the server this connector is on, and copy its URL (
https://cloud.anythingmcp.com/mcp/…). Use it wherever this guide showsYOUR_SERVER_ID.
Muse adds remote MCP servers as custom connectors and signs in to them with OAuth.
- In Muse, open Settings → Connectors and choose Add custom connector.
- Paste the MCP server URL
https://cloud.anythingmcp.com/mcp/YOUR_SERVER_ID. - Muse opens the AnythingMCP sign-in page: sign in and approve access.
- In a chat, ask Muse for something that needs the
Buffertools.
You can also set it up from a chat, on the web, in the iOS and Android apps or in WhatsApp. Send Muse this message:
Create a Custom Connector for a new remote MCP server, then connect to it:
Name: AnythingMCP
Transport: remote streamable HTTP
URL: https://cloud.anythingmcp.com/mcp/YOUR_SERVER_ID
Auth: OAuth
Self-hosting? Use your instance's public HTTPS address instead of https://cloud.anythingmcp.com. Muse connects from Meta's cloud, so localhost does not work.

FAQ
Where is Muse available? Meta currently offers Muse in the US and Canada, on the web, in the iOS and Android apps and in WhatsApp.
Does Meta review this connector? No. Meta doesn't review custom connectors. Muse sees only the tools you switched on for this MCP server in AnythingMCP, and you can disconnect it anytime under Settings → Connectors.
