Rival Regulatory Toolkit

Rival Regulatory Toolkit runs locally from a Node.js package published to the npm registry: @tryrival/regulatory-toolkit version 0.1.5. It speaks MCP over stdio, so the client starts it as a program and talks to it through standard input and output. It needs Node.js; clients usually start it with npx — the usual command is npx -y @tryrival/regulatory-toolkit@0.1.5. It reads these environment variables: RIVAL_API_KEY (required, secret), RIVAL_API_BASE_URL and RIVAL_FIXTURE_MODE; set them in the client's configuration for this server.

In the mcpServers JSON format that many desktop and editor MCP clients read, the entry looks like this (placeholders in angle brackets):

{
  "mcpServers": {
    "rival-regulatory-toolkit": {
      "command": "npx",
      "args": [
        "-y",
        "@tryrival/regulatory-toolkit@0.1.5"
      ],
      "env": {
        "RIVAL_API_KEY": "<secret>",
        "RIVAL_API_BASE_URL": "<value>",
        "RIVAL_FIXTURE_MODE": "<value>"
      }
    }
  }
}
