MCP and API
Connect ChatGPT, Claude, Gemini, Codex, Cursor, Grok Bot, Hermes Agent or any MCP app to your workspace. Plan your posts, write your emails, build landing pages and set up DM automations in a conversation. Included from the Starter plan.
You already ask ChatGPT or Claude for ideas. Connect Postfjord, and the same chat can do the work too: plan your week of posts, write the email, build the page and set up the DM that answers people. It all lands in your Postfjord workspace, in your brand voice, ready for your yes.
01
You ask in your AI app, the way you would ask a person on your team. Postfjord reads what it needs from your workspace: your brand voice, your calendar, your contacts and how your posts did. Then it makes the drafts and shows them to you. Nothing goes out until you say so.
What it does
02
"Which posts did best last month? Plan three more like them for next week." Your AI app reads your numbers and your calendar, finds the empty days and writes posts in your voice. They land in the calendar as drafts, with the photos from your media library. Move one, rewrite one, or schedule them all.
03
"Email the best one to my list." You get an email draft in your brand colors, with your logo on top and a button to book. Ask how last week's email did, which link got the most clicks, or how many people are on your list. The email goes out only when you schedule it.
04
"Make a page for the free class." Your AI app builds a landing page on your own address at postfjord.page, with your photos, your links and a signup form that adds people to your list. It stays a draft until you publish it, and every link is checked first.
05
"DM everyone who comments CLASS the booking link." Your AI app sets up the automation on Instagram or Facebook: the keyword, the reply, the link and a follow-up. It starts paused. Look at it, then say yes, and it switches on.
06
The same connection works for AI agents that keep working on their own. Grok Bot and Hermes Agent sign in over MCP, and we tested both on October 6, 2026. Meta Muse connects through the API, and OpenAI Dots use ChatGPT's plugins. Building your own agent? Any agent that speaks MCP or calls a REST API can connect with a key. See every agent and how to connect it.
07
In ChatGPT or Claude, add a connector with the address mcp.postfjord.com/mcp and sign in to Postfjord. You pick the workspace and what the app may do, and press Allow. No key to copy, nothing to install. Gemini CLI signs in the same way after you add the address to its settings file. Grok Bot and Hermes Agent sign in the same way. Codex, Cursor and VS Code connect with a key from Settings, and the help page has each setup ready to copy.
08
Every connection has one level, and you choose it. Read only lets the app look and change nothing. Drafts only lets it write drafts, and nothing goes out. Schedule and publish lets it put things out when you ask. Each connection reaches one workspace, and you can remove it under Settings at any time.

10
The same things are there as a REST API with a key for each workspace, so Zapier, Make, a spreadsheet script or your own code can create posts, emails and pages and read the results.
ChatGPT on plans that let you add your own connectors, Claude on claude.ai and in its desktop and phone apps, Gemini through Gemini CLI, and Codex, Cursor, VS Code and any other app that speaks MCP. Grok Bot and Hermes Agent sign in over MCP, and Meta Muse connects through the API.
Only if you let it. With Read only or Drafts only, nothing goes out. With Schedule and publish, it puts out what you ask for in the chat. A new DM automation always starts paused, and an email goes out only when it is scheduled.
Starter, Solo, Studio and Agency. Free does not.
Each connection belongs to one workspace and has one level: read only, drafts only, or schedule and publish. Keys are shown once and stored hashed. Remove a connection or a key under Settings, and it stops at once.
No. Postfjord runs the server for you. In ChatGPT or Claude you sign in and press Allow. For the other apps you copy one line or a few lines from the help page.
MCP and the API come with the Starter, Solo, Studio and Agency plans. Connect in a minute, no code needed.
