## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-09-20.

- **Supply Chain Security**: 23/100
  - Malware scan not yet available for this package.
  - Known CVEs were checked across the 110 of 110 dependencies we could resolve, so this covers what we could see, not the whole tree.
  - No install/post-install scripts declared.
  - 31 of 110 dependencies flagged as unhealthy.
- **Provenance & Transparency**: 45/100
  - Source repository is publicly reachable at the declared URL.
  - Provenance check failed: no build-provenance attestation is published.

- **Schema Quality & AI Usability**: 86/100
  - AI-judged instruction clarity (excellent).
  - Tool/resource definitions use about 442 tokens (~63/item across 7 items; 7 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 87/100
  - Stability observed for 26 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 7 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 7 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (7)

### `getChainlinkPrice` (~93 tokens)

Fetches the latest on-chain Chainlink price for a pair on a supported chain (e.g. ETH/USD on ethereum). Flags the result as stale if the feed's own on-chain timestamp is older than 1 hour.

Input parameters:

- `chain` (string, required): Chain name, e.g. ethereum, base, arbitrum, polygon, optimism
- `pair` (string, required): Feed pair, e.g. ETH/USD

### `getChainlinkRoundPrice` (~94 tokens)

Fetches a specific historical Chainlink round via getRoundData(roundId) — a real historical lookup, not a re-fetch of the latest round.

Input parameters:

- `chain` (string, required): Chain name, e.g. ethereum, base, arbitrum, polygon, optimism
- `pair` (string, required): Feed pair, e.g. ETH/USD
- `roundId` (string, required): Chainlink round ID as a string

### `listChainlinkFeeds` (~25 tokens)

Lists all supported chains and Chainlink pairs in this server's curated registry.

### `getPythPrice` (~86 tokens)

Fetches the latest price from Pyth Network's Hermes API for a symbol (e.g. SOL/USD) or a raw Pyth feed ID. Pyth's catalog covers far more assets than a static registry, including many not on Chainlink.

Input parameters:

- `symbol` (string, required): Symbol, e.g. SOL/USD, or a 64-hex-char Pyth feed ID

### `getPythHistoricalPrice` (~64 tokens)

Fetches Pyth's price as of a specific unix timestamp (seconds).

Input parameters:

- `symbol` (string, required): Symbol, e.g. SOL/USD, or a 64-hex-char Pyth feed ID
- `unixTimestamp` (integer, required): Unix timestamp in seconds

### `searchPythFeeds` (~58 tokens)

Searches Pyth Network's live feed catalog by symbol substring (e.g. 'SOL' or 'gold'). Useful for discovering feed coverage beyond this server's curated Chainlink list.

Input parameters:

- `query` (string, required): Symbol substring to search for

### `listSupportedChains` (~22 tokens)

Lists blockchain networks with curated Chainlink feed coverage in this server.
