BiglySales MCP Server

Connect Claude, ChatGPT or any MCP client to your BiglySales workspace and configure the AI sales assistant that calls and texts your leads, by chatting instead of clicking through settings.

This is a hosted (remote) MCP server. There is nothing to install or run. This repository holds the public listing, connection details and registry metadata; the server itself runs at BiglySales.

Server URL	https://app.biglysales.com/mcp
Transport	Streamable HTTP
Authentication	OAuth 2.1 (sign in with your BiglySales account), or a workspace access token
Documentation	docs.biglysales.com/mcp

What you can do

• Review and change AI settings such as timezone, guard rails and whether AI is enabled.
• Edit the company variables, intros, opening messages and qualifying questions your assistant uses.
• Switch the voice assistant's LLM, voice or speech-to-text model and tune its prompt.
• Manage the SMS agents that answer inbound texts.
• Set up follow-up sequences, first-day follow-ups and working hours.
• Manage outbound webhooks, AI tool settings and Web Calling (embed snippet and allowed domains).
• Preview the exact context your assistant will use on a call, without placing one.

It does not read or edit contacts, lists, calls, messages, billing or phone numbers, and it never places calls or sends messages.

Safe by design

• Every change is shown to you as a preview first and is only applied after you confirm it.
• Credentials and API keys are entered in the BiglySales app, never in chat. Stored ones always come back masked.
• Credit data is never shown.
• Each connection is tied to you and to one workspace, and every change is audited.

Requirements

• A BiglySales workspace with MCP access enabled. If it isn't enabled for your account, contact support.
• A role that includes MCP access. Owners and admins have it by default.

Connect

Full step-by-step instructions are at docs.biglysales.com/mcp/connect.

Claude (web, desktop and mobile)

1. In Claude, open Customize › Connectors › Add custom connector.
2. Name: BiglySales, Remote MCP server URL: https://app.biglysales.com/mcp.
3. Click Connect, sign in to BiglySales, pick a workspace and click Allow.

Claude Team and Enterprise Owners can add the connector for the whole organization.

ChatGPT

Add a custom MCP server with the URL https://app.biglysales.com/mcp and Authentication set to OAuth (leave client ID and secret empty), then sign in and allow access.

Claude Code, Codex, Cursor, VS Code, Windsurf, Gemini CLI and other clients

These clients connect with a workspace access token:

1. In BiglySales, open the MCP setup screen and generate an access token. It is shown only once; treat it like a password.
2. Copy your workspace's MCP URL from the same screen. It ends in /api/v2/mcp.
3. Add the server to your client with the header Authorization: Bearer <token>.

The setup screen generates the exact snippet for each client. For example, Claude Code:

claude mcp add biglysales --transport http <your-workspace-mcp-url> --header "Authorization: Bearer <token>"

Cursor (~/.cursor/mcp.json):

{
  "mcpServers": {
    "biglysales": {
      "url": "<your-workspace-mcp-url>",
      "headers": { "Authorization": "Bearer <token>" }
    }
  }
}

You can revoke a token, or disconnect an OAuth app, at any time from the BiglySales app.

Tools
