How to connect Phorest to Claude Code, ChatGPT and any AI agent

Name: Phorest MCP Server and API by Cotlet
Author: cotlet

Yes, Claude, ChatGPT and other AI agents can work in your Phorest account. Phorest offers an API for custom integrations, but there is no official Phorest app in ChatGPT or connector in Claude. Cotlet.dev connects your own signed-in Phorest account to any AI agent, so you can ask in plain words and the AI books, rebooks and checks clients for you.

What you can ask

Book Sarah Murphy for a cut and colour with Aoife on Thursday at 11 am.

Show me tomorrow's appointments per stylist and any gaps longer than 45 minutes.

Which clients haven't been in for 8 weeks? List them with their last service and stylist.

Move all of Ciara's Saturday appointments to Niamh and keep the same times.

Add a note to Tom Byrne's client card: allergic to ammonia, use the gentle range.

Connect in 2 minutes

Get your API key at https://cotlet.dev/app and export it as COTLET_API_KEY.

Claude Code

bash

claude mcp add --transport http cotlet https://cotlet.dev/mcp/v1 --header "Authorization: Bearer $COTLET_API_KEY"

ChatGPT

Settings → Apps → add connector URL https://cotlet.dev/mcp/v1, then sign in with Cotlet.dev. No API key needed.

Cursor

Copy .cursor/mcp.json from this repo into your project:

json

{
  "mcpServers": {
    "cotlet": {
      "url": "https://cotlet.dev/mcp/v1",
      "headers": {
        "Authorization": "Bearer ${COTLET_API_KEY}"
      }
    }
  }
}

Run it locally (stdio)

This repo is a real MCP server. It speaks MCP over stdio, lists its Phorest tools without any key, and forwards every tool call to the hosted Cotlet.dev server. The hosted URL above stays the recommended way. Use this when your client only starts local servers.

json

{"mcpServers":{"phorest":{"command":"uvx","args":["phorest-mcp"],"env":{"COTLET_API_KEY":"your-key"}}}}

Or with Docker:

bash

docker build -t phorest-mcp .
docker run -i --rm -e COTLET_API_KEY phorest-mcp

Tools: phorest_guide, phorest_status, phorest_open, phorest_read, phorest_click, phorest_type, phorest_close. Without COTLET_API_KEY a tool call answers: "Set COTLET_API_KEY. Get a key at https://cotlet.dev/app".

Command line

Python 3.10+, nothing else to install. From PyPI:

bash

pip install phorest-mcp        # or run it once: uvx phorest-mcp connect
phorest-mcp connect

Or straight from this repo:

bash

export COTLET_API_KEY="your-key"
python3 phorest_agent.py connect   # ready config for Claude Code, Cursor, ChatGPT
python3 phorest_agent.py status    # is Phorest ready in your Cotlet.dev account
python3 phorest_agent.py guide     # Phorest screens and sign-in link
python3 phorest_agent.py read      # open Phorest, read the page, close the browser
python3 phorest_agent.py tools     # list Cotlet.dev tools
python3 phorest_agent.py serve     # start the stdio MCP server (same as no argument)

Questions from Phorest users

Does Phorest have an API?

Phorest has an API, but credentials come only through Phorest Support with your account number, and setup needs your own development team. Cotlet.dev works in your own signed-in Phorest account instead, so your AI agent can book appointments and manage clients without code.

How do I connect Phorest to ChatGPT?

Add Cotlet.dev as an app in ChatGPT (Settings → Apps, connector URL https://cotlet.dev/mcp/v1), sign in to Phorest once in your Cotlet.dev Cloud Browser, and ask ChatGPT in plain words. No code and no Phorest API key.

Is there a way to use Claude with Phorest?

Yes. In Claude Code run the one-line claude mcp add command above; in the Claude app add https://cotlet.dev/mcp/v1 as a custom connector. Claude then works in your own Phorest account.

Is there a Phorest MCP server?

Phorest has no official MCP server and no official app in ChatGPT or Claude (checked November 2026). Cotlet.dev is a hosted Phorest MCP server that works in your own account, with Claude, ChatGPT, Cursor, Codex, n8n, Make and Zapier.
