Connect Planther to your AI assistant
Use Planther's planning data and tools right inside the AI you already use. Pick your assistant below and follow the steps. It takes about a minute.
Planther connects using a secure open standard called MCP. In practice, you just paste one link and sign in. Nothing to install, no code.
Which AI assistant do you use?

Click Add, then click Connect.
- 6
Sign in to Planther and click Allow.
- 7
In any chat, click the "+" in the message box and switch Planther on.
On Claude's Free plan you can add one connector. On Claude Team or Enterprise, your Claude workspace owner may need to add it first, then you click Connect.
Connect Planther to ChatGPT
Requires Plus, Pro, Business, Enterprise or Edu (not Free)
- 1
Open ChatGPT in a web browser and sign in.
- 2
Go to Settings, then "Apps & Connectors".
- 3
Open "Advanced settings" and turn on "Developer mode".

In a chat, open the tools ("+") menu and enable Planther.
Add it on the web first; it then appears on the ChatGPT desktop and mobile apps. On ChatGPT Business, Enterprise or Edu, your workspace admin may need to switch Developer mode on. On ChatGPT Plus and Pro, Planther can read planning data; full actions need Business or above.
Connect Planther to Le Chat
Works on all plans, including Free
- 1
Open Le Chat (chat.mistral.ai) and sign in.
- 2
In the sidebar, open "Intelligence", then "Connectors".

Name it "planther" (no spaces) and paste in this link:
https://mcp.planther.co.uk - 6
Save, then sign in to Planther to authorise.
This refers to your Le Chat account (not Planther): you need to be the account owner, which you are by default on a personal plan. On a Mistral Team or Enterprise workspace, an admin may need to add it.
Connect Planther to Gemini
Not yet supported in the Gemini app
Google's Gemini app doesn't let you add custom connectors like Planther yet. If you're comfortable using developer tools you can connect Planther through the free Gemini CLI. Otherwise we'd suggest Claude, ChatGPT or Le Chat for now. We'll update this page the moment the Gemini app supports it.
The Planther link:
https://mcp.planther.co.ukConnect Planther to Copilot
Not available in the everyday Copilot app
Microsoft's everyday Copilot doesn't support custom connectors like Planther. If your organisation uses Microsoft 365 Copilot, your IT administrator can add Planther for your whole team; send them this page and the link below. Developers can also connect Planther in VS Code (GitHub Copilot).

Any tool that supports MCP
Most AI tools that support MCP can connect to Planther, including Cursor, VS Code, Cline, Zed and Claude Code. Add a new MCP server using the link below, set the type to HTTP (or "streamable"), and the tool will usually open a sign-in window for you.
