## 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 117 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 554 tokens (~110/item across 5 items; 5 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **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.

**Unverified: 1 category.** A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

## MCP tools (5)

### `gas_check_tank` (~63 tokens)

Check gas credit balance in The Agent Cafe paymaster. Returns credit balance in ETH/USD, estimated transactions remaining, tank health status, and next-action suggestion. No API key needed.

Input parameters:

- `wallet` (string): Wallet address to check. Defaults to deployer wallet.

### `gas_estimate` (~126 tokens)

Estimate gas cost for a transaction on any EVM chain. Returns cost in ETH and USD at slow/standard/fast speeds, whether the paymaster can cover it, and optimal timing advice. No API key needed.

Input parameters:

- `chain` (string): Chain name or ID (default: base)
- `data` (string): Transaction calldata (hex encoded). Omit for simple ETH transfers.
- `to` (string, required): Destination address for the transaction
- `value` (string): ETH value to send (in ETH, e.g. '0.1'). Defaults to 0.

### `gas_price_history` (~86 tokens)

Get gas price trends for the last N hours. Returns average/min/max prices, current percentile, cheapest time windows, and trend direction. Useful for deciding when to send transactions. No API key needed.

Input parameters:

- `chain` (string): Chain name or ID (default: base)
- `hours` (number): Hours of history to analyze (default: 24, max: 24)

### `gas_optimize_batch` (~102 tokens)

Analyze a batch of transactions for gas optimization. Calculates total cost, identifies which can be batched via Multicall3, estimates savings, and recommends whether to send now or wait. Premium tool — pass api_key for unlimited access.

Input parameters:

- `api_key` (string): Premium API key for unlimited access
- `chain` (string): Chain name or ID (default: base)
- `transactions` (array, required): Array of transactions to analyze (1-50)

### `gas_send_sponsored` (~177 tokens)

Send a transaction sponsored by The Agent Cafe paymaster. Checks gas tank credits first, submits via paymaster if sufficient, returns tx hash and remaining credits. Premium tool — pass api_key for unlimited use. Set confirm: true to execute.

Input parameters:

- `api_key` (string): Premium API key for unlimited access
- `chain` (string): Chain name or ID (default: base). Currently only Base is supported for sponsored txs.
- `confirm` (boolean): Set to true to actually send. When false, returns a dry-run estimate.
- `data` (string): Transaction calldata (hex encoded). Omit for simple ETH transfers.
- `to` (string, required): Destination address for the transaction
- `value` (string): ETH value to send (in ETH, e.g. '0.1'). Defaults to 0.
