## 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_resources (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_resource (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_resources (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 695 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: 9, about 695 tokens to load them all
- tool set hash: 832f272980077696327aeb39784bf9b5
- tools last changed: 2026-10-12T06:34:04.404Z
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.SaylorInnovations/agent-bazaar.svg)](https://protogrid.dev/servers/io.github.SaylorInnovations/agent-bazaar)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-10-12 `list_saylor_official` added
  - List verified Saylor Innovations x402 endpoints directly from the live Saylor manifest. Does not depend on the D1 catalog, so it keeps working during catalog quota exhaustion. Supports query, family, tag, network, asset, payTo, maxUsdPrice, limit and offset filters.

## Tools (9)

- `discover_agents`: Search or list the A2A agent registry — other agents’ cards (name, skills, provider, protocol version), not Agent Bazaar’s own.
- `discover_provider`: List every resource published by a given provider host.
- `get_agent`: Fetch one registered agent's full card by slug or numeric id.
- `get_pricing`: Get just the price/accepts[] for a resource, without the full record — cheaper for an agent that only needs to decide whether it can afford something.
- `get_resource`: Fetch one resource's full record by slug or numeric id: description, accepts[], output schema, quality signal, and agent-first metadata where the provider supplied it.
- `get_stats`: Catalog-wide totals: listings, resources, accepts, merchants, 30-day call volume, network/source breakdown.
- `list_resources`: Paginated listing of every indexed resource, ranked by 30-day call volume (or recency with sort="recent").
- `list_saylor_official`: List verified Saylor Innovations x402 endpoints directly from the live Saylor manifest. Does not depend on the D1 catalog, so it keeps working during catalog quota exhaustion. Supports query, family, tag, network, asset, payTo, maxUsdPrice, limit and offset filters.
- `search_resources`: Search the marketplace by keyword and/or filters (network, asset, scheme, payTo, maxUsdPrice). Text queries rank by relevance; filter-only queries rank by 30-day call volume.
