## Quality 79/100 (good)

### 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: 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: search (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); describe (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); call (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 529 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`: no 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 529 tokens to load them all
- tool set hash: 97c7b71c200121781c0c61beed50830f
- badge: [![protogrid quality](https://protogrid.dev/badge/market.mcp/gateway.svg)](https://protogrid.dev/servers/market.mcp/gateway)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (4)

- `balance`: Prepaid balance, today's spend, and this key's caps.
- `call`: Run one tool on a listed server. The gateway meters the call, enforces your spend caps, and logs reliability data. F-graded servers are blocked.
- `describe`: Full detail for one server: user rating and what reviewers said, safety grade and scan summary, adoption, price, and every tool with its input schema and whether it performs write actions.
- `search`: Find MCP servers for a job in plain words. Results are ranked by user rating first, then adoption. Each hit carries its rating, safety grade and adoption score. D and F grades are hidden unless min_grade says otherwise.
