Nutshell CRM + ChatGPT
Manage Nutshell CRM (leads, contacts, accounts, activities, tasks) from any AI agent. 9 tools, basic-auth with API token.
Prerequisites
See the full setup instructions baked into the connector (visible in the in-app store when you select the connector). The required environment variables for this connector are:
NUTSHELL_USERNAME, NUTSHELL_API_KEY
Step 1 — Get credentials
This connector wraps the Nutshell REST API v1 (app.nutshell.com/api/v1).
Setup:
- Log into https://app.nutshell.com → top-right avatar → Setup → API → New API key.
- Note the
Username(your Nutshell email) and the generatedAPI key. - Set
NUTSHELL_USERNAME(email) andNUTSHELL_API_KEY.
Authentication: HTTP Basic — username = your account email, password = the API key. Nutshell ALSO supports a legacy JSON-RPC API but the REST endpoints exposed here are easier to consume.
Entity types: Lead (the main pipeline opportunity), Contact (person), Account (company), Activity (call/meeting log), Task (todo). Each has its own endpoint root.
…(continued in the in-app connector instructions)
Step 2 — Install the adapter
curl -fsSL https://raw.githubusercontent.com/HelpCode-ai/anythingmcp/main/docker-compose.quickstart.yml -o docker-compose.yml
printf 'JWT_SECRET=%s\nENCRYPTION_KEY=%s\n' "$(openssl rand -hex 32)" "$(openssl rand -hex 32)" > .env
docker compose up -d
Step 3 — Add the connector in ChatGPT
Your server URL: in AnythingMCP, open MCP Servers → the server this connector is on, and copy its URL (
https://cloud.anythingmcp.com/mcp/…). Use it wherever this guide showsYOUR_SERVER_ID.
ChatGPT connects to MCP servers as custom apps in developer mode, available on paid plans (not on Free). On Business and Enterprise workspaces an admin may have to allow it first.
- In ChatGPT, open Settings → Security and login and turn on Developer mode.
- Go to chatgpt.com/plugins and click +.
- Enter a name and a short description, e.g. Name:
Nutshell CRM. - Under Connection, enter the MCP server URL
https://cloud.anythingmcp.com/mcp/YOUR_SERVER_IDand create the connection. - When ChatGPT asks, sign in to AnythingMCP (OAuth) and allow access.

FAQ
Does the free ChatGPT plan work with custom MCP connectors? No. Custom MCP connections need developer mode, which is only on paid plans.
