List operations from the bundled OpenAPI spec for an `ad_type`, with optional filters.
describe_endpoint
Return one operation plus the `components.schemas` reachable from it (its `$ref` closure), so request bodies and responses can be built without the full spec.
call_endpoint
Execute any Sam's Club Sponsored Ads API endpoint. Identify it by `operation_id`, or by raw `method` + `path`. Raw method+path also reaches endpoints not yet in the bundled spec. The server handles RSA-SHA256 signing.
refresh_specs
Re-fetch the bundled OpenAPI spec from its committed `source_url` into a user cache (`~/.cache/mcp-samsclub-ads/specs/`) that takes precedence over the bundled copy — ship fixes without a release.
