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

30/30 tools missing one or more hints — remote_add_config (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); remote_bash (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); remote_connect (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +27 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

6 tools describe read intent but their handlers mutate — remote_glob (line 29: conn.sshPool.exec(rgCmd, { timeout: 30_000 })); remote_grep (line 37: conn.sshPool.exec(cmd, { timeout: 30_000 })); remote_read (line 65: conn.sshPool.exec(`if [ -d ${quoteShell(remotePath)} ]; then echo "DIR"; elif [ -f ${quoteShell(remo…)

Rename the tool, rewrite the description, or move the side-effect into a separate clearly-named tool.

Tool inputs are validated

26/30 tool handlers declare input schemas (87%)

Declare an inputSchema with zod/joi/yup on every tool definition.

Tool handlers catch errors

18/30 tool handlers wrap calls in try/catch (60%)

Wrap each tool handler body in try/catch and return a structured error response.

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.

Shell command execution

40 child_process calls — runs shell commands

Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.

Tool description accuracy

6 tools have description/behavior mismatches: remote_glob: description implies read-only but handler writes/deletes/executes; remote_grep: description implies read-only but handler writes/deletes/executes; remote_read: description implies read-only but handler writes/deletes/executes

Update tool descriptions to accurately reflect all capabilities — especially write, delete, or execute operations.
