## 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**: 79/100
  - No malware found by supply-chain analysis.

  - No install/post-install scripts declared.
  - Only part of the dependency tree could be resolved (130 of 131), 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 111 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 688 tokens (~98/item across 7 items; 7 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 27/100
  - Stability observed for 8 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 (7)

### `pentagonal_generate` (~142 tokens)

Generate a production-quality smart contract from a natural language description. Supports EVM (Solidity) and Solana (Anchor/Rust or SPL Token config). The generator uses Pentagonal's self-learning security rules to produce safer code.

Input parameters:

- `chain` (string): Target blockchain
- `prompt` (string, required): Natural language description of the smart contract to generate. Be specific about features, access control, and tokenomics.
- `solana_type` (string): For Solana only: "program" for Anchor/Rust programs, "token" for SPL token JSON config
- `use_learned_rules` (boolean): Inject self-learning security rules into generation prompt

### `pentagonal_lookup` (~187 tokens)

Look up any token or smart contract by address. Returns the full intelligence report: price, market cap, ATH, 24h volume, transactions, holders, liquidity, LP lock status, pool count, security flags (honeypot, mintable, pausable, hidden owner, taxes), social links, and source code if verified. Use this before auditing to understand the full token landscape. Supports EVM and Solana tokens.

Input parameters:

- `address` (string, required): Contract address. EVM: 0x... checksum or lowercase. Solana: base58 program address.
- `chain` (string): Target blockchain
- `fields` (array): Which data sections to return. "all" returns everything. Use specific fields for faster, focused queries — e.g. ["security"] for just flags, ["price", "market"] for market data, ["code"] for source o…

### `pentagonal_audit` (~125 tokens)

Run an 8-agent security pen test on a smart contract. Each agent specializes in a different attack vector: reentrancy, flash loans, access control, gas griefing, oracle manipulation, front-running, integer overflow, and economic exploits. Findings are returned with severity ratings and line numbers. New security rules are automatically learned from each audit.

Input parameters:

- `chain` (string): Which blockchain the contract targets
- `code` (string, required): The full smart contract source code to audit
- `use_learned_rules` (boolean): Use previously learned security rules during the audit

### `pentagonal_fix` (~95 tokens)

Fix a specific vulnerability in a smart contract. Provide the contract code and the finding details — returns the complete fixed contract preserving all existing functionality.

Input parameters:

- `code` (string, required): The full smart contract source code to fix
- `finding_description` (string, required): Detailed description of the vulnerability and how it can be exploited
- `finding_title` (string, required): Short title of the vulnerability (e.g., "Reentrancy in withdraw()")

### `pentagonal_compile` (~73 tokens)

Compile Solidity source code and return the ABI, bytecode, constructor arguments, and gas estimates. Use this after generating and auditing a contract to prepare it for deployment.

Input parameters:

- `code` (string, required): Solidity source code to compile
- `contract_name` (string): Specific contract name to compile (auto-detected if omitted)

### `pentagonal_rules` (~39 tokens)

Get the current self-learning security rules. These rules are accumulated from every audit Pentagonal performs — the more contracts audited, the smarter the system gets.

### `pentagonal_chains` (~27 tokens)

List all supported blockchains with their chain IDs, explorer URLs, and deployment hints.
