Tool Annotations

All 57 tools carry MCP annotations so clients can reason about safety and retry behavior.

Market data tools (52):

Annotation	Value	Meaning
readOnlyHint	true	Tools never modify data
destructiveHint	false	No destructive side effects
idempotentHint	true	Safe to retry on failure
openWorldHint	true	Queries an external API

Web3 tools (5): readOnlyHint: false, idempotentHint: false — these create accounts, keys, and subscriptions.

All tools also declare an outputSchema so clients can validate structured responses.
