Our reading of LeanGate, from the data

LeanGate is a security MCP server from lambdabypi, listed in the official MCP Registry.

We haven't measured its tool list yet, so its token cost is unknown.

It runs locally on your machine over stdio and needs 2 secrets (NEBIUS_API_KEY, OPENROUTER_API_KEY); use a scoped, least-privilege key.

Install LeanGate MCP server

claude mcp add leangate -e NEBIUS_API_KEY='<nebius-api-key>' -e OPENROUTER_API_KEY='<openrouter-api-key>' -- uvx leangate mcp

{
  "mcpServers": {
    "leangate": {
      "command": "uvx",
      "args": [
        "leangate",
        "mcp"
      ],
      "env": {
        "NEBIUS_API_KEY": "<nebius-api-key>",
        "OPENROUTER_API_KEY": "<openrouter-api-key>"
      }
    }
  }
}

Add to ~/.cursor/mcp.json (global) or .cursor/mcp.json (project).

{
  "mcpServers": {
    "leangate": {
      "command": "uvx",
      "args": [
        "leangate",
        "mcp"
      ],
      "env": {
        "NEBIUS_API_KEY": "<nebius-api-key>",
        "OPENROUTER_API_KEY": "<openrouter-api-key>"
      }
    }
  }
}

Settings → Developer → Edit Config (claude_desktop_config.json), then restart.

{
  "servers": {
    "leangate": {
      "type": "stdio",
      "command": "uvx",
      "args": [
        "leangate",
        "mcp"
      ],
      "env": {
        "NEBIUS_API_KEY": "<nebius-api-key>",
        "OPENROUTER_API_KEY": "<openrouter-api-key>"
      }
    }
  }
}

Add to .vscode/mcp.json in your workspace.

{
  "mcpServers": {
    "leangate": {
      "command": "uvx",
      "args": [
        "leangate",
