## 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 (104 of 108), 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 (104 of 108), so this covers what we could see, not the whole tree.

  - 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 148 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).
  - Tool/resource definitions use about 459 tokens (~57/item across 8 items; 8 tools + 0 resources), lean.
  - 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.

First indexed and scored.

## MCP tools (8)

### `scan_contract` (~53 tokens)

Analyze a smart contract on Base mainnet for security issues including reentrancy patterns, access control, hidden mints, proxy patterns, and dangerous opcodes.

Input parameters:

- `address` (string, required): Contract address on Base mainnet

### `check_honeypot` (~61 tokens)

Check if a token on Base mainnet is a honeypot by simulating buy and sell via Uniswap V2 router. Returns buy/sell ability and estimated taxes.

Input parameters:

- `token_address` (string, required): Token contract address on Base mainnet

### `detect_rug_risk` (~59 tokens)

Score rug pull risk 0-100 for a token on Base mainnet. Checks ownership, liquidity, dangerous functions, honeypot status, and contract patterns.

Input parameters:

- `token_address` (string, required): Token contract address on Base mainnet

### `analyze_bytecode` (~55 tokens)

Disassemble contract bytecode on Base mainnet and identify known patterns (proxy, diamond, AMM, lending, ERC-20, ERC-721, etc).

Input parameters:

- `address` (string, required): Contract address on Base mainnet

### `check_token_permissions` (~52 tokens)

Check owner permissions on a token: can mint? can pause? can blacklist? can change fees? Can disable trading? Ownership renounced?

Input parameters:

- `token_address` (string, required): Token contract address on Base mainnet

### `get_contract_info` (~60 tokens)

Get basic contract metadata on Base mainnet: is it a contract, bytecode size, ETH balance, transaction count. For tokens, also returns name/symbol/supply.

Input parameters:

- `address` (string, required): Contract or EOA address on Base mainnet

### `compare_bytecode` (~56 tokens)

Compare bytecode of two contracts on Base mainnet for clone detection. Returns similarity score and whether they share the same code.

Input parameters:

- `address1` (string, required): First contract address
- `address2` (string, required): Second contract address

### `audit_report` (~63 tokens)

Generate a full security audit report for a token on Base mainnet. Combines contract scan, honeypot check, rug risk score, bytecode analysis, and permission checks into one comprehensive report.

Input parameters:

- `token_address` (string, required): Token contract address on Base mainnet
