0xArchive MCP Server

Query crypto market data across Hyperliquid, HIP-3, and Lighter.xyz using natural language in Claude.

57 tools covering orderbooks, trades, candles, funding rates, open interest, liquidations, data quality metrics, and wallet-based authentication — from April 2023 to real-time.

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.

Smart Defaults

Time range: Defaults to last 24 hours if not specified
Limit: Defaults to 100 records
Interval: Defaults to 1h for candles
Pagination: Returns cursor for next page when more data available
Timestamps: Accepts both Unix milliseconds and ISO 8601 strings
