Your selected X account is ready.
Connect your social accounts in Monthly first. Then add Monthly to the agent you already use.
In Claude, open Customize → Connectors → Add custom connector. Enter the address below, choose Sign in now and Register automatically, and keep Streamable HTTP.
https://app.monthly.so/mcpUse your own Monthly account. Keep accounts:read and posts:read selected; leave drafting/media and scheduling/cancellation off. Select only your intended accounts.
Ask Claude to list the accounts this Monthly connection can access. The result should match your selection. No post needs to be created or published.
For read-only setup, also set Claude’s Write/delete tools to Blocked.
Connect and enable your publishing account in Monthly first. On a managed Claude workspace, an owner may need to add or permit the connector.
Open Customize → Connectors in Claude. Use Add connector → Add custom connector; check Yours first to avoid adding the same connection twice.
Name the connector Monthly and enter the HTTPS URL below. Choose Continue and wait for Claude to check the server and sign-in provider.
Select Sign in now and Register automatically. Under Advanced, keep Streamable HTTP. This server uses DCR rather than Claude’s published identity documents.
Choose Add, then Connect. On Monthly’s consent page, keep only the two read permissions selected. Leave drafting/media and scheduling/cancellation off. Select only your intended account and choose Allow selected access.
In the connected Monthly connector, set the Write/delete tools group to Blocked for this read-only setup. Keep the read-only tools on Needs approval. Monthly also enforces the selected OAuth permissions on its server.
Open a new chat and check Add files, connectors, and more → Connectors has Monthly enabled. Send the read-only check below. Use Allow once for the requested read tools and confirm the returned accounts match your selection.
https://app.monthly.so/mcpClient instructions checked October 26, 2026. Claude custom connector documentation. Private Claude OAuth and read-only profile/capability/account/draft-status checks passed on October 26, with both write permissions off and Claude’s write/delete tools blocked. Drafting, scheduling, client revocation/reconnection and directory review remain unverified.
Copy a prompt after connecting Monthly, or open it in Claude with one click — automatically typed in, waiting for you to press Enter. Opens the desktop app. Install it and connect Monthly there first; your browser may ask you to confirm opening it.

Use Monthly to show the social accounts I’ve allowed this connection to access and which are ready to publish. Read only; don’t create or schedule anything.

Read actual delivery status, without guessing.

Keep the agent’s access easy to understand.
What is this Monthly connection allowed to do, and which accounts can it access? Read only; don’t request or change any permissions.
Yes. Connect your social accounts in Monthly, then sign in to your own Monthly account during your agent’s OAuth flow. Each customer gets their own scoped connection; you never use another customer’s login or social credentials.
Only the accounts you select during consent and the permissions you allow. Post reads are limited to posts created by that same connection. Your social access tokens and passwords stay in Monthly.
The read-only setup on this page cannot create or schedule posts. If you later grant drafting and scheduling permissions, every exact draft revision still needs your approval inside Monthly before it can be scheduled. Editing a draft clears its approval.
Compatible MCP clients use OAuth sign-in and automatic client registration. You do not need to copy a Monthly API token or a shared client secret. Your agent’s account or subscription requirements are separate.
A client may need to renew authorization or reconnect an expired account. Use the normal sign-in flow and check the permissions again. Never disable authentication or share a social password with an agent.
Open Monthly Settings → AI agents & API and revoke that connection. Revocation stops further agent actions. It does not cancel posts already in your queue; review those separately.
Get started in minutes.
