## Trust

- hygiene: 100
- liveness: 100
- freshness: 100
- provenance: 90
- drivers: +repository +namespace-matches-repo +website +reachable +uptime-100% +updated-3d-ago
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 92/100 (new)

### 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 60000)

### 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: 86 (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`: 2 of 2 tools declare readOnlyHint or destructiveHint
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: prepare_interpretation_delta_purchase (destructiveHint, idempotentHint); prepare_state_deviation_purchase (destructiveHint, idempotentHint)
- pass `tools.token_cost`: about 556 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 2 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: 2, about 556 tokens to load them all
- tool set hash: 1a4761b6608fd9b2d3013d027f11a468
- tools last changed: 2026-10-20T01:18:18.103Z
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.417properties/big-machine-market.svg)](https://protogrid.dev/servers/io.github.417properties/big-machine-market)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-10-20 `prepare_state_deviation_purchase` changed (title, description) **meaning changed**
  - before: Browse the $0.001 primitive catalog. Create a purchase intent and pay only when /market.primitive_entry.paid_execution_enabled is true; otherwise paid execution is unavailable. Prepare a machine-payable x402 request that checks whether an observed state materially differs from an expected state. The paid result is binary 0/1; undecidable inputs abstain before billing.
  - after: Browse the $0.001 primitive catalog. Create a purchase intent and pay only when /market.primitive_entry.paid_execution_enabled is true; otherwise paid execution is unavailable. Prepare a machine-payable x402 request. Check whether an observed state materially differs from an expected state. Compare expected versus actual system state for exact text equality or explicit boolean and configuration polarity mismatch, such as enabled versus disabled. Binary 0/1 when decidable; abstains before billing otherwise. Current deterministic scope: exact normalized text equality returns 0; true/false, yes/no, enabled/disabled, present/absent, required/not required and allowed/not allowed return 1. Other inputs abstain before billing. This is not general language interpretation, diagnosis or a similarity score.
- 2026-10-20 `prepare_interpretation_delta_purchase` changed (title, description)
  - before: Machine-native checks from $0.001 USDC per successful execution. No subscription required for S0.1 primitives. Browse the $0.001 primitive catalog. Create a purchase intent and pay only when /market.primitive_entry.paid_execution_enabled is true; otherwise paid execution is unavailable. Prepare a machine-payable x402 request that checks whether an agent's current interpretation materially differs from the original human message. The paid result is binary 0/1; undecidable inputs abstain before billing.

Create a purchase intent and pay only when /market.primitive_entry.paid_execution_enabled is true; otherwise paid execution is unavailable. Prepare a machine-payable x402 request. Check whether an agent's current interpretation materially differs from the original human message. Bounded instruction comparison: exact text equality or explicit boolean and permission polarity mismatch. Binary 0/1 when decidable; abstains before billing otherwise. Current deterministic scope: exact normalized text equality returns 0; true/false, yes/no, enabled/disabled, present/absent, required/not required and allowed/not allowed return 1. Other inputs abstain before billing. This is not general language interpretation, diagnosis or a similarity score.
