## 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: find_tools (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); report_unmet_need (readOnlyHint, destructiveHint, idempotentHint, openWorldHint)
- pass `tools.token_cost`: about 554 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

- 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)

## Tools (2)

- `find_tools`: Free. Free search across public agent-tool catalogs — paid x402 APIs and MCP tools (PayAI's x402 Bazaar) and MCP servers (the official MCP Registry). Describe what you need in plain words; get matching tools with price, payment networks and how to call them. Returns up to 10 matches with kind (x402-http, x402-mcp, mcp-remote, mcp-package), URL, price per call in USD when listed, payment networks, and a one-line howToUse. `matched: false` means nothing covered your request well.
- `report_unmet_need`: Free. Nothing fits? Say what you needed (free, no personal information): the report_unmet_need MCP tool, or POST https://subpay.ai/api/v1/find/unmet. It decides what gets built next.
