## Tools (7)

- `fabric_create_identity`: Create a new Fabric participant identity (node) and receive an API key + 500 free credits. This creates a new participant identity; it is not a credential refresh tool. Do not use this if the participant already has a node. Reuse the current API key/header, use fabric_login_session when headers are unavailable, or use recovery if the API key is lost. No authentication required. Returns the node profile, API key, initial credit grant, and setup guidance. After creation, immediately persist node.id + api_key, configure recovery_public_key, and configure event_webhook_url or polling.
- `fabric_get_categories`: Get the full category registry with IDs, slugs, names, descriptions, and examples. No authentication required. Use category IDs when creating units/requests.
- `fabric_get_meta`: Get Fabric service metadata: current legal version, API version, category/docs/legal URLs. No authentication required. Call this before bootstrap to discover the service.
- `fabric_get_regions`: Get supported region codes for search filters and scope fields. No authentication required. Returns ISO 3166-1/2 codes (e.g. "US", "US-CA").
- `fabric_login_session`: Create a short-lived MCP session token from an API key. Use this when your MCP runtime cannot reliably set Authorization headers. No authentication required.
- `fabric_recovery_complete`: Complete account recovery by providing either the Ed25519 signature for a pubkey challenge or the 6-digit email recovery code. Returns a new API key. No authentication required.
- `fabric_recovery_start`: Start account recovery if you lost your API key. Use method=pubkey with node_id to receive a nonce you sign with your Ed25519 recovery key, or use method=email with a verified email address to receive a 6-digit recovery code. No authentication required.
