ChatGPT + MonthlyBring your Monthly accounts, publishing formats and post status into ChatGPT. One connection. Only the access you choose.
ChatGPT 
MonthlyWhich of my connected accounts are ready for my next post?
Your selected X account is ready.
Connect your social accounts in Monthly first. Then add Monthly to the agent you already use.
In ChatGPT Plugins, choose Add custom MCP server. Enter the address below, choose OAuth and automatic registration (DCR). In Advanced OAuth settings, select accounts:read and posts:read only.
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 ChatGPT to list the accounts this Monthly connection can access. The result should match your selection. No post needs to be created or published.
No API token or shared client secret is needed for this OAuth flow.
Have a Monthly account, an active supported plan and an enabled account in Settings → Integrations. Your ChatGPT account or workspace must allow custom MCP servers.
In ChatGPT Plugins, use the plus button and choose Add custom MCP server. This creates a personal or workspace connection, not a public directory listing.
Name the connection Monthly, enter the HTTPS URL below, and choose OAuth. Open Advanced OAuth settings and use Dynamic Client Registration (DCR).
Under Default scopes, select accounts:read and posts:read only. Leave drafts:write and posts:schedule off and Base scopes empty. Review the server risk notice, then create the personal plugin.
Choose Connect, sign in to Monthly and check that consent requests only account and draft-status reads. Select only the accounts you want to share. Stop if the permissions are broader than expected.
Choose Try in chat on the resulting plugin, or select it in a conversation. Send the read-only connection check below and confirm that the returned accounts match your selection.
https://app.monthly.so/mcpChoose OAuth, not No authentication. Use dynamic client registration (DCR) when the setup asks how to register this connection. You do not need a Monthly API token or a shared client secret for this flow.
Client instructions checked October 26, 2026. OpenAI connection documentation. Private ChatGPT OAuth and read-only account/capability/draft-status checks passed on October 26. Drafting, scheduling, client revocation/reconnection and public directory review are not verified by that check.

See exactly which accounts this connection can access.
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.
Know what needs reconnecting before you begin.
Check my selected Monthly accounts for connection issues. Tell me which need reconnecting and what to do next. Don’t change anything.
Check text lengths, image limits and supported formats.
Which formats can my selected Monthly accounts use? Show text lengths, image limits and file sizes. Read only; don’t upload or create anything.
Bring connection-created drafts back into view.
Show drafts created by this Monthly connection with their review links and approval status. Don’t edit, approve or schedule anything.
Read actual delivery status, without guessing.
Did posts created by this Monthly connection publish? Show their observed status and any delivery receipt IDs. Don’t retry or cancel anything.
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.
