Google Health — Agent Plugins package

Portable Agent Plugins v1 package for Hermes Agent and other Agent Plugins clients: the google-health MCP server (google-health-mcp-unofficial@0.8.0 over stdio) plus the google-health-mcp workflow skill.

Install (Hermes Agent)

hermes plugins install davidmosiah/google-health-mcp/agent-plugin --no-enable
hermes plugins enable google-health-mcp

Requires Node.js 20+ (npx on PATH). The skill loads as google-health-mcp:google-health-mcp.

Connector setup

npx -y google-health-mcp-unofficial@0.8.0 setup --client generic
npx -y google-health-mcp-unofficial@0.8.0 auth
npx -y google-health-mcp-unofficial@0.8.0 doctor

setup asks for the Google Health developer app client ID and secret and saves them locally (--client generic because this plugin already registers the server with Hermes); auth opens the Google Health consent page in the browser and stores the OAuth tokens under ~/.google-health-mcp/ with 0600 permissions; doctor confirms readiness.

Disclosure

Runs the google-health-mcp-unofficial@0.8.0 npm package locally over stdio through npx (Node.js 20+ required); the package is downloaded from npm on first start. Data source: the official Google Health API v4 (Fitbit and Pixel Watch data) with Google OAuth 2.0. Credentials and OAuth tokens are created by the connector's own setup/auth commands in the user's terminal and stay on the machine (~/.google-health-mcp/); the plugin declares no environment variables and reads no Hermes credentials. Tools that change state: google_health_profile_update (local profile only); google_health_exchange_code (stores OAuth tokens locally); google_health_revoke_access (revokes the Google Health grant and deletes local tokens). The tool set comes from the pinned npm version, not from this repository's source tree.
