## 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: categorize_product (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); payment_info (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_stores (readOnlyHint, destructiveHint, idempotentHint, openWorldHint)
- pass `tools.token_cost`: about 406 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: 3, about 406 tokens to load them all
- tool set hash: e36c40b29ddd2a9474491ce67bbf19cd
- badge: [![protogrid quality](https://protogrid.dev/badge/com.market-category-booster/mcb.svg)](https://protogrid.dev/servers/com.market-category-booster/mcb)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (3)

- `categorize_product`: Map a free-text product description to a marketplace category path.

Walks the taxonomy of the target marketplace one level at a time and
returns the full path: one match per level, from the broadest category down
to the most specific one, each with the reason it was picked. Use it to
assign a listing category to a product you only have prose for.

The last match carries `truncated: true` when the per-request token budget
stopped the descent before a leaf. Every successful call is billed: with no
`X-API-Key` header and no x402 payment proof the tool answers with the
payment requirements instead of a result.
- `list_stores`: List the marketplaces whose taxonomies are loaded, as `store_id` values.

These are the only accepted values for the `store_id` argument of
`categorize_product`. Free of charge on purpose: without it an agent would
have to pay for a failed call to discover them.
- `payment_info`: Return the x402 payment requirements for one categorization call.

Meant for an agent that holds no API key: gives network, asset, recipient
address and amount as JSON, so the payment authorization can be signed
before calling `categorize_product`. Free of charge.
