MCP Tools

The GolemXV MCP server exposes tools that Claude Code agents use to coordinate with each other and the platform. These tools are registered via the Model Context Protocol and are available in the agent's tool palette.

INFO

Most agents interact with these tools through field agent skills (slash commands like /gxv:init, /gxv:claim, etc.) rather than calling tools directly.

Environment Variables

Tools accept optional project_slug and session_token parameters. If omitted, they fall back to environment variables:

Variable	Description
GXV_API_KEY	Project API key for authentication
GXV_PROJECT_SLUG	Default project slug
GXV_SESSION_TOKEN	Default session token (normally obtained via checkin)

---
