MCP Gateway

Planned service

MCP Gateway is documented as the intended design for early adopters. It is not yet available as a deployable service or API contract.

MCP Gateway will provide a controlled boundary between AI clients and tools exposed through the Model Context Protocol (MCP). It is designed to make tool access discoverable, tenant-aware, observable, and policy-governed.

Intended capabilities

Capability	Intended behavior
Tool registry	Register and discover approved MCP servers and tools
Identity propagation	Carry authenticated user and tenant context to tool execution
Policy enforcement	Evaluate which caller may discover or invoke each tool
Audit trail	Emit records of tool discovery and invocation
Integration adapters	Connect MCP clients to Labs64.IO services and external tools

Design ahead

Plan tool boundaries around least privilege: define each tool’s input and output, identify the tenant context it needs, and decide which calls should be auditable. Do not depend on endpoint names, authentication details, or SDKs until the published API reference is available.
