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.
cloud189_statusShow safe storage status: login state, config dir, write root, token cache.
cloud189_rootsShow built-in root folder IDs.
cloud189_quotaShow account storage usage (total/used/available).
cloud189_listList files and folders in a remote folder.
cloud189_treeRecursively list remote content.
cloud189_searchSearch remote files and folders by keyword.
cloud189_downloadDownload a remote file or folder to a local path.
cloud189_upload_safeUpload a local file or directory into the configured agent write root without overwriting existing remote files.
cloud189_mkdir_safeCreate a folder directly inside the configured agent write root. Existing folders are reused.
cloud189_sync_upload_safeRun a deletion-free one-shot upload sync into the configured agent write root.
cloud189_planCreate a dry-run plan for a dangerous operation. The plan is informational and does not execute.
cloud189_rename_folderRename a remote folder.
cloud189_rename_fileRename a remote file (custom patch, uses the official renameFile API).
cloud189_rmDelete a remote file or folder. DANGEROUS. Use cloud189_plan first to preview.
cloud189_mvMove a remote file or folder to another folder. DANGEROUS. Use cloud189_plan first to preview.
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
15/15 tools missing one or more hints — cloud189_status (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); cloud189_roots (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); cloud189_quota (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +12 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.
Descriptions match behaviour
5 tools describe read intent but their handlers mutate — cloud189_roots (line 30: execFileSync(process.execPath, [...DNS_ARGS, CLOUD189_CLI_JS, ...args, '--json'], {); cloud189_quota (line 30: execFileSync(process.execPath, [...DNS_ARGS, CLOUD189_CLI_JS, ...args, '--json'], {); cloud189_list (line 30: execFileSync(process.execPath, [...DNS_ARGS, CLOUD189_CLI_JS, ...args, '--json'], {)
Rename the tool, rewrite the description, or move the side-effect into a separate clearly-named tool.
Tool inputs are validated
12/15 tool handlers declare input schemas (80%)
Declare an inputSchema with zod/joi/yup on every tool definition.
License file
No license file
Add a LICENSE file (MIT, Apache-2.0, etc.).
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@1.17.5 (high), @modelcontextprotocol/sdk@1.17.5 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
Tool description accuracy
5 tools have description/behavior mismatches: cloud189_roots: description implies read-only but handler writes/deletes/executes; cloud189_quota: description implies read-only but handler writes/deletes/executes; cloud189_list: description implies read-only but handler writes/deletes/executes
Update tool descriptions to accurately reflect all capabilities — especially write, delete, or execute operations.

Add it once and ask Claude, ChatGPT, or any MCP client to grade a server, surface CVEs, check the publisher, and suggest safer alternatives — before you install.
