How do I install the Presidio plugin?

`pip install mcp-gateway[presidio]` installs the extra dependency required for PII masking.

Does MCP Gateway require an API key?

Only the `lasso` plugin requires a `LASSO_API_KEY` environment variable (obtained from Lasso Security). The other plugins work without an external API key.

What credentials does it need?

It reads `LASSO_API_KEY`, `XETRACK_DB_PATH`, `XETRACK_LOGS_PATH`, `PYTHON_PATH` from the environment. Store these in your client's env block or a secrets manager — never commit them to a repository — and grant the narrowest scope that still covers your use case.

What is the MCP Gateway MCP Server?

A plugin-based gateway that orchestrates other MCPs and allows developers to build upon it enterprise-grade agents.

What the server does

MCP Gateway is an advanced intermediary solution for Model Context Protocol (MCP) servers that centralizes and enhances your AI infrastructure.

Credentials and setup notes

Obtain a Lasso API key by signing up at Lasso Security. To use Lasso Security's advanced AI safety guardrails, update your mcp.json configuration as follows: 1. Add the LASSO_API_KEY=<YOUR-API-KEY> to your environment variable or in the "env" section. 2. Insert other MCP servers configuration under key servers Example:

Frequently asked questions

The README describes three guardrail plugins: `basic` (secret masking), `presidio` (PII masking), and `lasso` (full security guardrails). There is also a tracing plugin called `xetrack`.
