Secure MCP Gateway

Secure MCP Gateway is an open-source Python gateway that sits between MCP clients and MCP servers, authenticates access, discovers and filters available tools, caches configuration and tools, and supports configurable guardrails for server requests and responses.

Understand the project

Practical overview

When it fits

Use it when an MCP deployment needs an administrative gateway layer for authentication, tool selection or configurable request and response checks.

Who it is for

  • Teams integrating MCP servers with AI clients
  • Operators who want a configurable intermediary for MCP authentication, tool access and guardrails

Documented uses

  • Place a gateway between an MCP client and one or more MCP servers.
  • Authenticate access to the gateway.
  • Discover server tools and limit which tools are exposed.
  • Configure input and output guardrails for MCP server interactions.
Before you choose

Requirements & limits

The project is publicly available under the Apache-2.0 license. The README documents pip installation and a Docker image. Enkrypt cloud configuration requires an Enkrypt API key.

  • The gateway acts as both an MCP server toward its client and an MCP client toward connected servers.
  • Tool restrictions and guardrails are configured; the listed protections are not necessarily active by default.
  • Local and Enkrypt cloud configuration are both documented.
  • Optional sandbox isolation is documented for Docker, Podman or microVMs.
  • The README describes forwarding logs to Enkrypt for monitoring as coming soon.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Install the package and generate a local configuration

Prepare a local Secure MCP Gateway installation and create its initial configuration file.

Before you start

  • Python environment capable of creating a virtual environment
  • pip

Steps

  1. Create and activate a virtual environment.

  2. Install the package with pip install secure-mcp-gateway.

  3. Run secure-mcp-gateway generate-config to create the configuration file.

Expected outcome

The package is installed in the virtual environment and a local gateway configuration file is generated.

Guide limitations

  • This covers installation and configuration generation, not running or connecting the gateway.
  • The generate command does not overwrite an existing configuration by default.

Source-based practical guide

Generate a cloud-backed configuration

Create a configuration that sources gateway server, project and user settings from Enkrypt cloud.

Before you start

  • Secure MCP Gateway installed
  • Enkrypt cloud API key

Steps

  1. Run secure-mcp-gateway generate-config --provider enkrypt.

  2. Fill in the Enkrypt API key in the generated configuration.

Expected outcome

A minimal cloud-provider configuration is generated with an Enkrypt API key and base URL fields, plus Enkrypt authentication and guardrail provider settings.

Guide limitations

  • The guide covers generating and filling in the configuration, not connecting to or operating the gateway.
  • The Enkrypt cloud API key must be supplied by the user.
