Cursor is an AI code editor with a built-in agent. Add PostQueen to its MCP settings and the agent can write posts about what you shipped, schedule them and report how your published posts did, without leaving the editor.
A sample Cursor terminal session with PostQueen connected: a request for posts, the PostQueen tools it used, and the reply

Before you start

  • Plans: Cursor lists MCP on its paid Individual plan. For the free Hobby plan, check cursor.com/pricing.
  • Platforms: macOS, Windows and Linux.
  • A PostQueen API key. A workspace admin copies it, or the ready-made address, from Connections.
Where the API key is: in the app, open Connections > API Keys. Only a workspace Admin or Super Admin can reveal or rotate it; other members see it masked. A workspace has one key, and each agent card on Connections shows your MCP address with the key already filled in.

Connect Cursor

1

Open mcp.json

Open ~/.cursor/mcp.json to use PostQueen in every project, or .cursor/mcp.json in a project to keep it to that one. In the app, MCP servers are under Customize > MCPs.
2

Add PostQueen

Add the postqueen entry, with your key in place of YOUR_API_KEY, and save:
~/.cursor/mcp.json
3

Check it in Cursor

Open Customize > MCPs and check that PostQueen is listed and on.

Check that it works

Ask Cursor’s agent: “List my PostQueen channels.” It calls PostQueen and answers with the channels you connected.

Good to know

  • The file holds your key when you use the key address. Keep .cursor/mcp.json out of version control, or use the header form below.
  • Cursor’s agent can add the entry for you if you allow it to edit mcp.json.
  • Grok Bot runs on Cursor’s cloud, but it does not read Cursor’s mcp.json. It has its own setup.
  • Ask for drafts when you want to check first. A draft waits on your PostQueen calendar, and nothing publishes until you schedule it.
  • What it cannot do over MCP: delete a post, or change a post’s text or time. Do that on the calendar in the app. The MCP tools lists what it can do.

Other ways to connect

Cursor fills in ${env:NAME} from your environment, so the key stays out of the file:
~/.cursor/mcp.json

Try this first

The draft appears on your PostQueen calendar, ready for you to check and schedule. Prompts to try has more.
