Scanned 27 days ago Due for re-check
A server can change after it's graded. Re-run the automated scan to refresh this report.
This grade is deterministic and reproducible: the same server surface always yields the same grade under a given algorithm version. It is a real automated assessment computed by the MCPGrade engine from what the probe actually observed — not a fabricated or opinion score. It is not a manual human pentest, so it can miss context-specific risks.
Every signal below was measured directly by the automated probe. The grade is derived only from evidence like this — nothing is assumed.
The tessera-hyperliquid-data MCP server exposes 6 tools, focused primarily on database and web capabilities. Its published description reads: "Hyperliquid perp market data for LLMs: OHLCV, funding, open interest, positioning, and forecasts". It communicates over Streamable HTTP using the 2026-07-28 protocol revision, and does not require authorization to connect. MCPGrade currently rates tessera-hyperliquid-data F — a critical issue was found and the server should not be connected as-is. Its most notable findings include "Cross-tool shadowing" and "Cross-tool shadowing". This report is a deterministic, reproducible automated assessment: the same observed surface always yields the same grade under a given algorithm version, and it is refreshed as new scans arrive and free to read — but it is not a substitute for a manual human security review. Always re-check tessera-hyperliquid-data's advertised tools, transport security, and authorization posture before connecting an autonomous agent or sharing sensitive context with it.
Add tessera-hyperliquid-data to an MCP client using the endpoint below. Review the grade and findings above before granting an autonomous agent access.

The tools this server advertises via tools/list — names, purposes, and the parameters each accepts, exactly as enumerated read-only.
Read actual data rows from one (asset, coin, month) partition. Defaults to the latest 200 rows. Pass `columns` to limit width and `limit` (max 1000) to limit rows — a partition can be tens of thousand
Get the full data dictionary for one dataset: prose plus every column's type, nullability and plain-English meaning. Use before read_dataset to choose columns.
List a dataset's (coin, month) partitions the caller's plan can read. Defaults to a compact SUMMARY (coin/month counts, month range, totals) — pass summary=false to enumerate (paginated via limit/offs
List the available Tessera Analytics gold datasets with summaries and the plan (free/pro) each requires. Call first to discover what's available.
Return a short-lived presigned URL to download the full parquet for one (asset, coin, month) partition. Use for bulk access beyond read_dataset's row cap.
Rank all coins for one day of a daily cross-section dataset (one row per coin per day, e.g. gold_positioning_funding_factors_1d) in a single call. Pass `order_by` (a numeric column), `day` (YYYY-MM-DD
Sorted worst-first. Each finding shows its severity, what it means, its OWASP MCP Top-10 mapping, and a recommended fix — the check id links to the exact methodology row that produced it.
