What SkillHub exposes over MCP
Approved Skills can appear as MCP tools with names, descriptions, schemas, permissions, and runtime status.
Agent integrations
SkillHub MCP
MCP gives Agent clients a tool discovery and invocation shape; SkillHub adds registry, review, Project Key, and governance context.
Metadata discovery
Agents can inspect tool metadata before selecting a Skill, reducing blind prompt-only execution.
Runtime invocation boundary
MCP invocation still resolves through project policy, approval state, rate limits, and runtime governance.
Permission and policy checks
High-risk permissions, billing preview gates, and restricted states must remain visible before invocation.
REST vs MCP
REST is direct and simple for backends. MCP is stronger when an Agent client needs dynamic tool discovery and structured tool calls.
