What is an MCP Tool?

Definition

An MCP tool is a callable interface that exposes a workflow, action, or capability to an agent-ready environment through the Model Context Protocol. In Stackmint, workflows can be packaged so external agents or assistants can discover and call them under governed permissions.

Technical Anatomy

• Tool Definition: describes what the tool does and what inputs it accepts.
• Callable Workflow: connects the tool to a Branch, Bud, or capability.
• Permission Scope: controls which users, agents, or workspaces can call it.
• Execution Policy: applies budget, audit, approval, and safety rules.
• Result Contract: returns structured output back to the calling environment.

Enterprise Context

MCP tools let partners expose Stackmint capabilities beyond the native UI. A workflow can run inside an agent, assistant, Slack, CRM, or other connected environment while still respecting governance and client workspace boundaries.
