MCP turns prompts into actions
The Model Context Protocol makes tools reachable from agents. If every tool is reachable by default, prompt injection and agent mistakes become operational risk.
MCP server security
An MCP security gateway for controlled AI agent access
MCP servers expose real business capabilities to AI agents: databases, shells, SaaS APIs, browsers, logs, finance systems and internal services. AgentGate sits between agents and MCP servers, enforcing policy before each tool call reaches the upstream server.
What this page helps you solve
Understand how to secure Model Context Protocol servers with an MCP authorization proxy, access control, audit logs and human approval before a tool executes.

The risk buyers are trying to control
New tools appear faster than policy
Tool inventories change as teams add servers and integrations. Unknown or newly discovered tools should not be allowed silently.
Bypass risk is real
A gateway only protects traffic that passes through it. Teams need a clear control point and deployment model that makes the secure path the default.

The market is moving toward AI-specific runtime controls
These third-party benchmarks are not AgentGate performance claims. They explain why buyers now ask for governance, authorization, auditability and data protection before approving agentic workflows.

prompt injection is a top LLM risk
OWASP identifies prompt injection as a major LLM application risk that can lead to unauthorized access, data exposure and compromised decisions.
OWASP Top 10 for LLM ApplicationsHow AgentGate solves it
Default-deny gateway
A tool call with no matching policy is blocked. New agents and tools start from explicit authorization rather than implicit trust.
Tool inventory and risk labels
AgentGate discovers MCP tools, records schemas and capabilities, and surfaces high-risk functions before they are used in production.
Fail-closed enforcement
Policy, database or approval errors block execution instead of allowing unknown behavior through to upstream MCP servers.
Before and after AgentGate
Without runtime authorization
With AgentGate
Agents call MCP servers directly with broad access.
Agents call AgentGate, and AgentGate forwards only authorized tool calls.
Security teams learn about risky tools after usage.
Tool discovery and risk labels expose dangerous capabilities before rollout.
Logs sit inside scattered MCP services.
A tenant-scoped audit trail records every allow, deny, approval and error decision centrally.
Business outcomes
Safer MCP adoption
Teams can connect more MCP servers without turning every integration into an unrestricted agent capability.
Cleaner operations
Security, platform and engineering teams share one view of agents, tools, policies, approvals and audit events.
Stronger customer trust
Enterprise buyers can see how AI automation is governed before it touches their data or infrastructure.
Frequently asked questions
- What is an MCP authorization gateway?
- It is a control layer between MCP clients and MCP servers that evaluates each tool call before the upstream server receives it.
- Why is default deny important for MCP?
- MCP tools can expose sensitive or destructive actions. Default deny prevents new or unknown tools from becoming accessible without explicit policy.
- Can AgentGate protect multiple MCP servers?
- Yes. AgentGate is built around a registry of upstream MCP servers, discovered tools, tenant-scoped policies and per-agent credentials.
Govern MCP access before it becomes business-critical
Start a live workspace and place AgentGate in front of one MCP server to verify policy decisions, risk alerts and audit evidence.
