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