Close CRM + ChatGPT

Drive Close (sales-team CRM) from any AI agent: leads, contacts, opportunities, activities (calls/emails/SMS/notes), tasks, smart views and custom fields. 16 tools, API-key Basic-auth.

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:

CLOSE_API_KEY

Step 1 — Get credentials

close.com).

Setup:

  1. Sign in to Close → top-right avatar → Settings → Developer → API Keys → New API Key.
  2. Name it ('AnythingMCP'), copy the key (starts with api_). Set CLOSE_API_KEY.

Authentication: HTTP Basic auth with username=API_KEY and password empty. The adapter passes Authorization: Basic base64(API_KEY:). Same as Stripe's auth model.

…(continued in the in-app connector instructions)

Step 2 — Install the adapter

git clone https://github.com/HelpCode-ai/anythingmcp.git
cd anythingmcp && docker compose up -d

Step 3 — Add the connector in ChatGPT

ChatGPT supports MCP servers via the Connectors feature (Plus / Pro / Team / Enterprise plans). The free tier does not support custom connectors.

  1. Open ChatGPT → Settings → Connectors (or click the 🔧 icon in the composer → Manage connectors).
  2. Click "Add custom connector".
  3. Fill in:
    • Name: Close CRM
    • MCP server URL: https://cloud.anythingmcp.com/mcp
    • Authentication: Bearer token → paste your MCP API key (from AnythingMCP → Profile → MCP API Keys → New Key)
  4. Click Connect to authorize.
