## Quality 89/100 (new)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### 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: 100 (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
- pass `tools.annotations`: 3 of 3 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 603 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

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

- n/a `stability.changes`, `stability.rug_pull`: tool history recorded for 4 of the 7 days needed

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

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

- tools: 3, about 603 tokens to load them all
- tool set hash: 83e7ca16b98da06f68faea4143718210
- tools last changed: 2026-10-18T07:50:48.411Z
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.Bosacks/magneta-contract-risk.svg)](https://protogrid.dev/servers/io.github.Bosacks/magneta-contract-risk)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-10-18 `scoring_rubric` added
  - Return the exact rubric behind contract_risk_summary scores: points per flag, the level thresholds and what each flag means. Free, read-only, no parameters. Call it to explain a score to a user or to decide your own threshold before acting on a report.
- 2026-10-18 `supported_chains` changed (title, description, annotations) **meaning changed**
  - before: Free: list the chains this service can analyze.
  - after: List the EVM chains contract_risk_summary can analyze, as { chainId, name, testnet } objects. Free, read-only, no payment and no parameters. Call it when you need to map a chain name to its id or to check coverage before paying for a report.
- 2026-10-18 `contract_risk_summary` changed (title, description, inputSchema, annotations) **meaning changed**
  - before: On-chain smart-contract risk report (score 0-100, proxy, owner, risky selectors, source verification, static analysis). Costs $0.02 in USDC via x402.
  - after: Analyze a deployed smart contract and return a deterministic risk report: 0-100 score with level (low/medium/high/critical), proxy/upgradeability, owner and pause state, risky selectors found in the bytecode (mint, blacklist, fee/tax setters, pause, upgrade), SELFDESTRUCT/DELEGATECALL opcodes, source verification (Blockscout, Sourcify) and aderyn static-analysis findings. Use it before trading, bridging, approving or integrating a token or protocol contract; use supported_chains first if you are unsure the chain id is covered, and scoring_rubric to interpret the score. Paid: $0.02 in USDC on Base per call via x402. The first call answers with an x402 payment challenge; an x402-enabled client pays automatically and the same call then returns the report. Read-only, no side effects; failed analyses (not a contract, upstream data source down) are not charged; identical requests within 10 minutes return the cached report.
