Overview

From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.

Mobbin's official MCP server is available at https://api.mobbin.com/mcp via Streamable HTTP transport. For setup instructions and usage, see the documentation. To learn more about what you can do with the Mobbin MCP server, visit mobbin.com/mcp.

Setup

Mobbin is a hosted remote MCP server — there is nothing to clone, install, or run locally, and no API key to configure. Add it to your MCP client as a Streamable HTTP server:

{
"mcpServers": {
"mobbin": {
"url": "https://api.mobbin.com/mcp"
}
}
}

Some clients need the transport stated explicitly — in Cline, add "type": "streamableHttp" alongside url, otherwise it falls back to the legacy SSE transport and the connection fails.

On first use, your client opens a browser window to sign in to Mobbin and authorize access via OAuth.

Per-client, step-by-step instructions are at docs.mobbin.com/mcp/clients/overview. For the tools the server exposes, see docs.mobbin.com/mcp/features.

Questions

What is the Mobbin MCP server?

Official Mobbin MCP server repository

Is Mobbin safe to connect to an agent?

The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.

What credentials does Mobbin need?

No credential environment variables were found in its source, so it appears to need none.

How does Mobbin run?

It speaks streamable-http, so it runs as a service you connect to over the network.

How current is this page?

The grade is for one exact copy of the source (cf71b8f266ec), read on 2026-10-09. The repository is watched and re-audited when it changes.
