Where: Connect PostQueen at the top of the left rail. It opens Connections. Connections is where anything outside the app plugs into your workspace: AI agents over MCP, the postqueen CLI, the public API and automation tools. All of them use the workspace API key, and the cards show the address or header with your key already filled in.

​
Connect an agent

1

Find its card

Under Connectors, pick a card from Featured or from a category, or type its name in Search connectors.
2

Follow How to connect

The card opens on How to connect: the agent’s own steps, with the commands to copy.
3

Copy your address

The API key tab shows your key and, for an agent, the MCP URL with the key in it. Paste what the steps ask for into the agent.
4

Try it

When the card has Examples, try one of its prompts in the agent.
Only a workspace Admin or Super Admin sees the key. Other members see it masked, and pressing Reveal explains that “The API key is managed by admins”. Ask an admin to connect the agent, or to share the address with you. The agent pages in these docs say which setups PostQueen has tested: start at AI agents.

​
What Connections holds

​
Rotate the API key

1

Open API Keys

In Connections, choose API Keys in the Account group.
2

Rotate

Choose Rotate key, then Rotate to confirm. PostQueen makes a new key at once.
3

Update what used it

The old key stops working right away, so paste the new one, or the new MCP address, into every agent, script and n8n credential that used it.
A workspace has one key. Only an admin can reveal or rotate it.

​
Your MCP address

PostQueen has tested the key address (with Claude and ChatGPT) and the Bearer header (with Grok Bot). The sign-in address has not been tested end to end yet. Clients that still use the older SSE transport can connect to https://api.postqueen.ai/sse/YOUR_API_KEY.
docs.postqueen.ai/mcp is a different server: it searches these docs and cannot post. Use an address from the table above.

​
Developers and Approved Apps

  • Developers is for building your own product on PostQueen. An admin chooses Create OAuth App and fills in App Name, Description, Profile Picture and Redirect URL. The Client Secret is shown only when the app is created or the secret is rotated, so copy it then. A workspace has one OAuth app. See OAuth apps.
  • Approved Apps lists the apps you approved, with the date. Only an Admin or Super Admin can approve an app, and an approved app can act for the whole workspace. Choose Revoke to cut an app off.
