## 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 2026-08-03.

- **Supply Chain Security**: 87/100
  - No malware found by supply-chain analysis.
  - Only part of the dependency tree could be resolved (105 of 109), so this covers what we could see, not the whole tree.
  - No install/post-install scripts declared.
  - Only part of the dependency tree could be resolved (105 of 109), so this covers what we could see, not the whole tree.
- **Provenance & Transparency**: 45/100
  - Source repository is publicly reachable at the declared URL.
  - Provenance check failed: no build-provenance attestation is published.
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 118 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 77/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 503 tokens (~125/item across 4 items; 4 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 23/100
  - Stability observed for 7 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.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (4)

### `scanner_analyze_contract` (~132 tokens)

BEFORE interacting with ANY smart contract, call this to get a full security report. Fetches source code (if verified), analyzes bytecode, detects vulnerabilities (reentrancy, hidden mint, backdoors, proxy risks, access control issues), and returns a risk score 0-100 with actionable findings. One call = complete analysis.

Input parameters:

- `address` (string, required): Contract address to analyze (0x...)
- `api_key` (string): Premium API key for unlimited scans. Free tier: 5 scans/hour.
- `chain` (string): Chain: base, ethereum, arbitrum (default: base)

### `scanner_compare_contracts` (~134 tokens)

Compare two smart contracts to see which is safer. Detects clones (identical bytecode), compares risk scores, identifies differences in access control and vulnerabilities. Use when choosing between two similar contracts (e.g., two DEX routers, two token versions).

Input parameters:

- `address1` (string, required): First contract address to compare (0x...)
- `address2` (string, required): Second contract address to compare (0x...)
- `api_key` (string): Premium API key for unlimited scans. Free tier: 5 scans/hour.
- `chain` (string): Chain: base, ethereum, arbitrum (default: base)

### `scanner_check_address` (~115 tokens)

Quick safety check on any address — is it a contract or EOA? Verified? Has selfdestruct, proxy, mint, pause, or blacklist? Returns risk flags in <1 second. Use this for fast triage before deciding whether to run a full scanner_analyze_contract scan.

Input parameters:

- `address` (string, required): Address to check (0x...)
- `api_key` (string): Optional premium API key to bypass rate limits.
- `chain` (string): Chain: base, ethereum, arbitrum (default: base)

### `scanner_decode_calldata` (~122 tokens)

Decode raw transaction calldata into human-readable function calls. Identifies the function being called, decodes parameters, and flags dangerous operations (unlimited approve, delegatecall, ownership transfers). Use BEFORE signing any transaction you don't fully understand.

Input parameters:

- `abi` (string): Contract ABI as JSON string for full parameter decoding. If not provided, common selectors (ERC-20, Uniswap, etc.) are matched automatically.
- `api_key` (string): Optional premium API key to bypass rate limits.
- `calldata` (string, required): Raw calldata hex string (0x...)
