# StackOne: MCP vendor profile

StackOne runs a hosted MCP server and an enterprise Tool Gateway MCP that give agents 43,000+ actions across 630+ connectors, with per-account tool catalogs and StackOne handling provider authentication, as documented by the vendor. StackOne's hosted MCP server is at https://mcp.stackone.com/mcp, and ChatGPT, Claude or Cursor can connect by signing in with a StackOne login over OAuth (docs.stackone.com).

## What it does for this layer

StackOne says its connectors cover "43,000+ pre-built actions across 635 connectors", ready for MCP, A2A, CLI, SDK or API clients ([www.stackone.com](https://www.stackone.com/llms.txt), vendor's own claim). StackOne's Tool Gateway MCP is "the enterprise MCP gateway": one URL connects every employee's AI to business systems, with the IT team choosing access above the gateway ([www.stackone.com](https://www.stackone.com/platform/mcp/)). StackOne says agents sign in with MCP OAuth, scoped API keys or short-lived session tokens ([www.stackone.com](https://www.stackone.com/llms.txt)).

StackOne announced Tool Policies on its home page, described as AI agent permissions "down to the field" ([www.stackone.com](https://www.stackone.com/)). The StackOne MCP server generates its tool catalog from the account's configured connectors and enabled actions ([docs.stackone.com](https://docs.stackone.com/embed/call-actions/mcp)). StackOne provides a pre-built MCP server for each linked account, with authentication to third-party providers handled by StackOne ([docs.stackone.com](https://docs.stackone.com/embed/call-actions/mcp)).
