Connect Any other MCP client

The server is a standard MCP implementation, so anything that speaks the protocol will work.

Before you start

Create an API key in the app under Settings, then API Keys. Grant only the permissions this agent needs. The key is shown once. Replace pk_live_xxx in the snippets below with it.

Hosted endpoint

Recommended. Nothing to install, and it stays current without you upgrading anything.

text

POST https://mcp.planpo.st/mcp
Authorization: Bearer pk_live_xxx
Content-Type: application/json
Accept: application/json, text/event-stream

Local install

Runs the MCP server on your own machine through npx, so your key never leaves it. Needs Node 18 or newer.

bash

PLANPOST_API_KEY=pk_live_xxx npx -y planpost-mcp

Things that catch people out

The HTTP transport is stateless and POST only. GET returns 405 by design, because there is no session to resume.
Every request carries its own key, so one hosted endpoint serves many users safely.
Health check: GET https://mcp.planpo.st/health returns {"status":"ok"}.

Check it works

Ask the agent to list your connected accounts. If it comes back with them, all 47 tools are available.

prompt

Which social accounts do I have connected on planpo.st?
