 is the layer that lets AI agents call Nue's business logic as structured tools. Each Nue MCP server exposes a focused set of tools — products, quotes, billing, analytics — with explicit schemas, authentication, and error handling. An agent decides 

 to do; the MCP server runs the work against Nue's APIs and returns a structured result the model can read.

The same MCP servers power Nue AI inside the platform 

 are connectable from external clients (Claude Desktop, Cursor, custom agents) — your tools and guardrails work the same way wherever you call them from.

 — connect Sigma, Gong, Fellow, or any MCP-compliant tool so Nue's agents can reach into the rest of your stack.

 — what MCP is, why we built it this way, and how to connect from any MCP client.

Splitting Nue's surface across multiple specialized MCP servers — rather than one monolithic server — gives admins and agents tighter control:

 A renewal motion doesn't need the product authoring tools. A pricing-rules edit doesn't need access to customer billing. Per-server tool sets keep prompts focused and reduce the chance of unintended actions.

 Admins can grant or revoke access at the server level. The audit trail records 

 New tools land on the relevant MCP without bloating others. The Lifecycle Manager team ships subscription tools without touching the Price Builder MCP's contract.
