Platform - MCP Gateway

Make MCP useful for developers and safe for security.

Model Context Protocol gives agents real tools: files, databases, ticketing, CRM, cloud APIs and business systems. AI Warden gives platform teams a governed path to register, scan, approve, publish and observe governed MCP servers and tool calls.

MCP adoption journey

From useful tool to governed enterprise capability.

The goal is not to ban MCP. The goal is to make the approved path simple enough for developers and controlled enough for security.

01RegisterAdd owner, endpoint, source, tools, data classification and intended consumers.
02ScanRun source, configuration, behavioural and live request/response checks.
03ApproveRoute risky tools, write actions, regulated data or broad access to reviewers.
04PublishExpose a governed endpoint with policy, DLP, logs and kill switch.

For AI developers

Use MCP without inventing your own security wrapper.

Developers can bring an MCP server, test it, see why a tool call was blocked, and publish it to approved agents or users without writing bespoke gateway logic.

  • Register a local, Kubernetes, VPC-hosted or third-party MCP server.
  • Declare tools, descriptions, permissions, secrets, environment and data classification.
  • Run test prompts and inspect tool arguments, results, latency, errors and policy decisions.
  • Connect approved clients and agents through a stable AI Warden MCP endpoint.
  • Observe usage, token impact and blocked calls after launch.

For security teams

MCP tools behave like API permissions. Treat them that way.

An MCP server can expose database reads, file access, email, ticket creation, customer records, cloud APIs or write actions. AI Warden applies familiar controls before agents get that power.

  • Default-deny registry for unknown or unapproved MCP servers.
  • Method-level firewall and allowlists by agent, user, group, product or environment.
  • Read/write separation so lookup tools do not imply action permissions.
  • Prompt-injection, SQL/shell injection, secrets, PII and custom scanner rules.
  • Quarantine, disable or revoke servers and tools without client redeployment.
Security questionAI Warden answer
Who owns this server?Registry owner and approval state are required.
Who can use this tool?Policy maps methods to users, groups, agents and products.
What data can leave?Request/response scanning and ICAP enforcement inspect tool traffic.
What happened?Governed calls can record principal, agent, method, arguments, result, latency and verdict.

Gateway controls

One supervised path for local, hosted and third-party MCP.

AI Warden supports the practical reality of enterprise MCP adoption: some servers are built by your teams, some are already running, and some come from vendors.

Source you control

Build, scan, sandbox, publish

Use source and behavioural checks before publishing a server to agents or employees.

Existing internal service

Register and proxy

Add owner, tier and data classification, then proxy calls through the gateway for scanning and logs.

Third-party MCP

Vetted external capability

Apply stricter DLP, egress and approval policy before agents can use vendor tools.

ICAP and scanner enforcement

Inspect tool arguments and tool responses before they create exposure.

MCP risk is not only which tool was called. It is what the model placed in the arguments and what the tool returned. AI Warden can inspect both sides with AI Warden rules and ICAP-supported DLP.

  • Block SQL injection, shell injection, prompt-injection payloads and high-risk method arguments.
  • Inspect tool responses for secrets, PII, regulated data or customer identifiers.
  • Fail closed where configured if required DLP inspection is unavailable.
  • Trigger session/tool containment after repeated block or modify outcomes.

MCP evidence

When an agent acts, the tool call is on the record.

AI Warden can record the user, agent, MCP server, method, arguments, response decision, scanner flags, ICAP result, latency, status and final outcome for governed tool calls.
