## Connection (mcpServers)

```json
{
  "mcpServers": {

      "type": "http",
      "url": "https://agent.zbang.net/api/mcp"
    }
  }

```


## Trust

- hygiene: 100
- liveness: 100
- freshness: 100
- provenance: 90
- drivers: +repository +namespace-matches-repo +website +reachable +uptime-99% +updated-29d-ago
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 88/100 (good)

### protocol: 100 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- pass `protocol.list_ttl`: tool list is cacheable (ttlMs 3600000)

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 71 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: list_watched_contracts (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_contract_powers (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); recent_power_changes (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 777 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: 1 tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 4, about 777 tokens to load them all
- tool set hash: 67565c623d224fce2744a35247f42ab6
- tools last changed: 2026-09-26T19:55:09.451Z
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.ofirbaranesad-agent/contract-powers.svg)](https://protogrid.dev/servers/io.github.ofirbaranesad-agent/contract-powers)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-09-26 `get_contract_powers` changed (description)
  - before: Full free analysis of one contract that is in the registry: verification, proxy pattern and implementation address, who the admin is and whether it is a single key, every retained power (upgrade / mint / pause / blacklist / fees / sweep / burn-from / ownership transfer / limits) with the evidence and confidence behind it, reachable DELEGATECALL / SELFDESTRUCT / CREATE2 opcodes, and the owner-only functions the classifier could NOT categorise — which is where the unusual powers hide. Accepts an address or a symbol such as USDC or AERO.
  - after: Full free analysis of one contract that is in the registry: verification, proxy pattern and implementation address, who the admin is and whether it is a single key, every retained power (upgrade / mint / grant-minter / pause / blacklist / seize / fees / sweep / burn-from / ownership transfer / limits) with the evidence and confidence behind it, reachable DELEGATECALL / SELFDESTRUCT / CREATE2 opcodes, and the owner-only functions the classifier could NOT categorise — which is where the unusual powers hide. Accepts an address or a symbol such as USDC or AERO.

## Tools (4)

- `check_any_contract`: Free preview for ANY verified EVM contract on base, ethereum or polygon — including addresses not in the registry. Returns contract type, verification, name, whether it is a proxy, how many powers were found, how many owner-only functions went uncategorised, and whether an owner was found. The decision fields (which powers, the evidence, the admin address, the implementation) are withheld and listed by name. Use get_contract_powers first if the contract is already in the registry — that is free and complete.
- `get_contract_powers`: Full free analysis of one contract that is in the registry: verification, proxy pattern and implementation address, who the admin is and whether it is a single key, every retained power (upgrade / mint / grant-minter / pause / blacklist / seize / fees / sweep / burn-from / ownership transfer / limits) with the evidence and confidence behind it, reachable DELEGATECALL / SELFDESTRUCT / CREATE2 opcodes, and the owner-only functions the classifier could NOT categorise — which is where the unusual powers hide. Accepts an address or a symbol such as USDC or AERO.
- `list_watched_contracts`: List the EVM contracts in the Contract Powers registry, with a one-line risk shape for each: is the code upgradeable, is the admin a single key (EOA) rather than a contract, how many powers are declared, and is it covered by a bug bounty. Use this to see what is already analysed before spending a lookup. Filters are optional and combine with AND.
- `recent_power_changes`: What actually changed behind the watched contracts: implementation swapped, owner moved, a power appeared or disappeared, verification lost. Each event carries the before and after value and the window it was detected in. Severity is one of critical / material / low. Use this to answer "has anything changed behind this contract recently?".
