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.
add-hostPersist a new SSH host configuration.
list-hostsList all stored SSH host configurations.
remove-hostRemove a stored SSH host configuration.
edit-hostEdit fields of an existing host configuration.
start-sessionStart a new SSH session for a stored host. Automatically initializes tmux if available (user can attach with the tmux session name returned in the response). Falls back to direct shell if tmux is not installed. IMPORTANT: Commands that install tmux itself should be executed BEFORE calling start-sess…
execExecute a shell command on an existing SSH session. When tmux is active, commands are automatically sent via tmux (non-blocking, user can observe with 'tmux attach -t ai'). IMPORTANT: Just pass the actual command to execute — do NOT manually write 'tmux send-keys' or 'tmux capture-pane', the plugin …
close-sessionClose an existing persistent SSH session.
upload-fileUpload a local file to the remote server via SFTP. PREFERRED method for writing files — more reliable than echo/cat/heredoc commands, handles binary content and special characters correctly.
download-fileDownload a file from the remote server via SFTP.
write-remote-fileWrite text content directly to a file on the remote server via SFTP. Preferred over echo/cat/heredoc for writing files — reliable, handles special characters, no shell quoting issues.
setup-tmuxInitialize tmux session on an existing SSH session. Use this after installing tmux on the remote server to switch from direct shell mode to tmux mode. When tmux is active, user can attach with the session name returned by start-session to observe commands in real-time.
forward-portCreate a local TCP port forward through the SSH session. Useful for accessing remote services (e.g. databases) locally. After calling this, connect to 127.0.0.1:<local_port> as if it were <remote_host>:<remote_port> on the server.
stop-forwardStop a port forward tunnel created by forward-port.
list-sessionsList all active SSH sessions with metadata.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
When Vitest UI server is listening, arbitrary file can be read and executed
@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
14/14 tools missing one or more hints — add-host (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list-hosts (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); remove-host (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +11 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
1 tool describes read intent but its handler mutates — list-hosts (line 256: mkdir(HOSTS_DIR, { recursive: true }))
Rename the tool, rewrite the description, or move the side-effect into a separate clearly-named tool.
Tool test coverage
Only 0/14 tools referenced in tests (0%)
Write tests that reference each tool by name so every tool has at least one test.
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.
Dev dependencies
1 critical/high in dev-only deps (does not ship to users)
Upgrade dev dependencies when convenient.
Tool description accuracy
list-hosts: description implies read-only but handler writes/deletes/executes
Update tool descriptions to accurately reflect all capabilities — especially write, delete, or execute operations.
