For Developers

Prefer the REST API or Self-Hosting?

The hosted connector covers most workflows. Call the Team REST API directly, or run the stdio MCP server yourself. See setup examples below.

    "sellinger": {
      "command": "node",
      "args": ["/path/to/mcp-server/dist/index.js"],

FAQ

Frequently Asked Questions About the MCP Connector

Everything you need to know about connecting Claude, ChatGPT, or any MCP client to Sellinger.

What is the Sellinger MCP connector?
MCP, the Model Context Protocol, is an open standard that lets AI assistants discover and call external tools. Sellinger runs a hosted MCP server at https://app.sellinger.ai/api/v2/mcp that connects Claude, ChatGPT and any compatible client straight to your workspace, with no local install required.
How do I connect it?
In claude.ai, open Settings, then Connectors, then Add custom connector. Paste the URL above, click Connect, sign in and pick a workspace and an access level. That is four clicks and your AI can read and act in your CRM. ChatGPT and other MCP clients use the same URL through their own connector settings.
Which AI assistants work with it?
Claude, through claude.ai custom connectors. ChatGPT, through its connectors and developer mode. Any other client that supports the streamable HTTP transport with OAuth works the same way. A legacy local stdio server also remains available in the repo for teams that prefer to self host.
What can my AI actually do with it?
27 tools across leads, prospecting, conversations, campaigns, approvals, meetings, analytics and search, plus 4 saved workflows: a weekly pipeline review, a daily prep briefing, ICP to prospect search, and stale lead audits. It can find new prospects, read every conversation across email, LinkedIn, WhatsApp, Instagram, SMS and voice, manage campaigns, work the approval queue and brief you before meetings.
Full access or read only, what is the difference?
You choose the access level when you connect. Full access lets the assistant read and act: send messages, update leads, approve outreach, import prospects. Read only lets it list and read everything with no sends, no writes and no approvals. You can reconnect at any time to change the level.
How is authentication handled?
OAuth. Access tokens last 8 hours and refresh automatically for up to 90 days, so reconnecting stays rare. Every connector request is logged for security auditing, and access ends immediately if you disconnect the connector or are removed from the workspace.
Is my data secure?
All traffic runs over HTTPS. Tokens are scoped to one workspace and one access level, requests are audit logged, and Sellinger does not use your data to train AI models. See our privacy policy for the full disclosure on AI assistant connectors.
Can I still use the REST API or a local server instead?
Yes. The Team REST API exposes 165+ endpoints under /api/v2/mcp for direct HTTP access and custom automations, and the stdio mcp-server package remains available in the repo if you would rather run the server yourself than use the hosted connector.
