FAQ

What is the Model Context Protocol (MCP)?

MCP is an open protocol that enables AI assistants like Claude to securely access external data sources. arvo-mcp lets Claude access your workout data, training history, and fitness metrics through natural conversation.

How is my data protected?

• API keys are hashed with SHA-256 (never stored in plaintext)
• All communication uses HTTPS encryption
• Keys can be revoked instantly from your dashboard
• Scoped permissions (read-only or read-write)
• Your API key is stored only on your local machine

Can I use this offline?

No, arvo-mcp requires an internet connection to communicate with arvo.guru servers. The MCP server runs locally but fetches your data from the cloud.

What AI clients are supported?

Claude Desktop, Cursor, Windsurf, and any MCP-compatible client. The server uses the standard MCP stdio transport, making it compatible with any client that supports the protocol.

How do I report security issues?

Email security@arvo.guru with details. See SECURITY.md for our full security policy and responsible disclosure process.

What data can the AI access?

The AI can access your workout plans, exercise history, personal records, body composition tracking, and coach notes. Write tools allow saving memories, updating preferences, and modifying workouts. You control access through API key scopes.

Does this work without an Arvo account?

No, you need an Arvo account to generate an API key. Sign up free at arvo.guru.
