- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 460 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 5 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 460 tokens to load them all
- tool set hash: 1a5748d2611c0c9dea516c1588b77e72

## Tools (2)

- `check_mcp_server`: Check a public remote MCP server URL (Streamable HTTP) for readiness for the Claude Directory, ChatGPT Apps, Gemini Connected Apps and the MCP Registry. Returns the 0-100 score, A-F grade, readiness per store, every failing or warning check with its fix, the report URL and README badge markdown. Results are cached for 10 minutes; set fresh to true to force a new check.
- `explain_check`: Explain one McpStamp Check rule by its id (for example tool_annotations or auth_prm): what it tests, why stores need it, which stores it blocks, its weight and the store or spec documents it comes from. Use it after check_mcp_server to understand a failing check.
