MCP Gateway
A gateway component based on the Model Context Protocol (MCP) that connects AI agents with external tools and services. It handles core functions including protocol forwarding, tool routing, identity authentication, access control, and auditing.
Core Facts
Timeline (last 90 days)
The MCP gateway acts as a unified entry point, encapsulating an enterprise's existing Java services, databases and third-party APIs into standardized tools for the agent to call on demand, lowering the marginal cost of tool integration.
In the governed enterprise path, AI agents should not connect directly to SAP but should go through the MCP gateway in SAP Integration Suite, which handles authentication, authorization, rate limiting, and payload protection.
Enterprises cannot let every Agent connect directly to various external services; an MCP gateway layer is needed to uniformly manage authentication, rate limiting, auditing, and policy enforcement.
An AI gateway controls what content enters and exits the model, whereas an MCP gateway controls what the model is permitted to do after it decides to take an action.
The principle of least privilege is considered one of the core ideas in agent security, meaning an agent should only be granted the minimum permissions necessary to complete its task.
The Sierra report compares the authorization issues of MCP gateways to an iceberg, with protocol forwarding, tool routing, and other direct implementations visible above the waterline, and identity, per-tool permission scopes, user consent, and auditing hidden below
An MCP gateway lacking audit capabilities is virtually unusable in a production environment
MCP gateways must support fine-grained per-tool permission scope control, for example allowing an Agent to read a calendar but not delete events
A mature MCP gateway needs a built-in user consent flow capable of triggering confirmation before an Agent performs high-risk actions, recording user authorization status, and updating permissions when authorization changes
Full-chain auditing should completely record the initiating user, the Agents traversed, the tool called, the input parameters, and the returned result for every tool call
