The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.
get_routes_metadata一次性返回所有路由的完整元数据（压缩 JSON，含 routeSlug、名称、说明、分类、市场类型、权限等级、queryParams、responseParams）。token 开销较大，仅当需要一次性拿到全部接口的完整字段定义、构建完整索引时使用。
get_user_profile查询当前 API Key 的账户与权限信息（压缩 JSON）：邮箱、订阅等级、可用市场、到期时间、账户是否有效、速率限制配置。仅在需要核对账户状态、可用市场范围或查看限流配额时调用。
configure配置 API Key 以访问数据服务，配置文件位于 ~/.cyberquant/config.json。不传任何参数时为「查询配置状态」（只读，返回是否已配置/endpoint/pageSize，不回显密钥、不写文件）；传入任意参数则为「写入配置」——apiKey 首次必填，配置文件已有 apiKey 时可省略（保留现有值）；endpoint 默认 https://api.cyberspace2077.com，通常无需传入；pageSize 可选（1~1000），省略则保留现有配置值。
get_route_detail查询单个路由的入参与返回字段详情，并附带通用传值格式说明。
list_routes列出当前用户可用的数据路由目录（轻量，仅 routeSlug、名称、说明、分类，不含入参/返回字段）。
query_data按参数查询指定路由的数据，返回 CSV 格式。需先用 `get_route_detail` 获取入参/返回字段说明，再据此组织 params 调用本工具。
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
@modelcontextprotocol/sdk has cross-client data leak via shared server/transport instance reuse
Anthropic's MCP TypeScript SDK has a ReDoS vulnerability
Model Context Protocol (MCP) TypeScript SDK does not enable DNS rebinding protection by default
Tool annotations
No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
6/6 tools missing one or more hints — get_routes_metadata (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_user_profile (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); configure (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +3 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Tool inputs are validated
Only 2/6 tool handlers declare input schemas (33%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tests exist
No test files found
Add tests that exercise each declared tool.
Production dependencies are patched
0 critical, 3 high severity in production deps — @modelcontextprotocol/sdk@1.12.0 (high), @modelcontextprotocol/sdk@1.12.0 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
