MCP Gateway

As enterprises connect agents to dozens of MCP servers, the absence of a central control point becomes the dominant risk. An MCP gateway provides the missing layer where consistent authentication, logging, and policy can be enforced regardless of which server is on the other end.

MCP gateways typically provide:

• Identity brokerage: Per-agent identity and OAuth on-behalf-of delegation.
• Tool-level policy: Allow, deny, and approval rules at the granularity of each MCP tool.
• Inspection: Inline scanning of inputs, outputs, and arguments for sensitive data or injection.
• Server inventory: Discovery and risk scoring of MCP servers across environments.
• Audit trail: Tamper-evident logs of every MCP call for compliance and forensics.

Without a gateway, every team integrating an MCP server ends up reimplementing the same authentication, logging, and policy logic. A central gateway shifts those concerns to a platform layer and gives security teams a coherent control point as the MCP ecosystem grows.

Gateway adoption also produces a clean evidence trail for audit and incident response, which is increasingly important as MCP integrations enter regulated workloads.

How PointGuard AI Helps

The PointGuard MCP Security Gateway delivers identity, authorization, observability, and threat detection for every MCP call, and pairs with the Agent Governance Mesh for end-to-end agent oversight. Operators get a coherent control point that scales as the MCP ecosystem grows without forcing every team to reimplement security from scratch.
