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.
sftp_listList a remote directory (read-only). Returns type/size/mtime/name per entry.
sftp_readRead a remote text file (read-only). Refuses files larger than SFTP_MAX_READ_BYTES.
sftp_writeWrite/overwrite a remote text file from inline content.
sftp_deleteDelete a remote file.
sftp_mkdirCreate a remote directory.
sftp_rmdirRemove a remote directory.
sftp_renameRename or move a remote file/directory (destination is guarded).
sftp_uploadUpload a local file to the remote host (for binary/large files).
sftp_downloadDownload a remote file to a local path (read-only).
sftp_statStat a remote path (read-only).
sftp_existsCheck whether a remote path exists (read-only). Returns false | 'd' | '-' | 'l'.
sftp_write_manyWrite many remote text files in parallel on one connection. Much faster than N sequential writes across a high-latency link.
sftp_delete_manyDelete many remote files in parallel on one connection.
sftp_upload_manyUpload many local files in parallel on one connection.
sftp_download_manyDownload many remote files in parallel on one connection.
sftp_sync_dirSync a local directory to a remote directory: upload files that are missing, size-different, or newer (parallel). Optionally delete remote files not present locally. Use dryRun 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

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
16/16 tools missing one or more hints — sftp_list (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); sftp_read (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); sftp_write (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +13 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.
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@1.12.0 (high), @modelcontextprotocol/sdk@1.12.0 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
