Trust breakdown (6 categories)

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score →

Endpoint Security46

The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
Authorisation not fully verified: no authorisation is required to call this server, and 9 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
HTTPS not yet verified: we couldn't determine whether a plaintext access path exists. View diagnostics → Unverified
HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail

Transport & Reachability100

Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass

Schema Quality & AI Usability61

AI-judged instruction clarity (excellent).Pass
Context-footprint check failed: tool/resource definitions use about 2312 tokens (~256/item across 9 items; 9 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
Usage-examples check failed: none of the tools include examples. See how to fix → Fail

Stability & Change Management27

Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial

Tool Coverage67

100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
0% of tool parameters carry a description.Fail

Capabilities100

Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

verify_claim ~569

Verify factual claims about current DeFi market conditions. Supports two modes: - Single claim: provide claim_type, value, operator (and protocol/chain/asset as needed). Returns one verification result. - Batch mode: provide a JSON-encoded array in 'claims'. Each element has the same fields (claim_type, value, operator, protocol, chain, asset). Returns all results in one response. If 'claims' is provided, single-claim parameters are ignored. Args: api_key: Your PreFlyte API key (required). claim_type: What you're checking. One of: "supply_rate" — current supply APY (%) "borrow_rate" — current borrow APY (%) "price" — current token price (USD) "gas" — current base fee (gwei) "utilization" — current pool utilization (%) value: The numeric value you believe to be true. operator: Comparison operator. One of: "above" — actual must be >= value "below" — actual must be <= value "around" — actual must be within 10% of value protocol: Required for supply_rate, borrow_rate, utilization. Use "aave-v3" or "compound-v3". chain: Chain name — "ethereum" or "arbitrum". Default "ethereum". asset: Required for supply_rate, borrow_rate, price, utilization.

Returns: Single mode: Dictionary with status (TRUE/FALSE), actual_value, claimed_value, delta, delta_pct, data_timestamp, and summary. Batch mode: Dictionary with 'mode', 'results' array, 'summary' counts, and 'verified_at' timestamp. Examples: Single: verify…
