VMware Workstation MCP

All four hints declared on every tool

14/14 tools missing one or more hints — server_info (missing: destructiveHint, idempotentHint); find_vms (missing: destructiveHint, idempotentHint); list_running_vms (missing: destructiveHint, idempotentHint), +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.

Tool annotations match behaviour

2 read-only tools perform write/delete/exec — list_running_vms (line 95: spawn(vmrun, args, {); list_snapshots (line 35: /^\/mnt\/([a-zA-Z])\/(.*)$/.exec(path))

Either remove the readOnlyHint:true annotation, or remove the write/delete call from the tool handler.

Descriptions match behaviour

2 tools describe read intent but their handlers mutate — list_running_vms (line 95: spawn(vmrun, args, {); list_snapshots (line 35: /^\/mnt\/([a-zA-Z])\/(.*)$/.exec(path))

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

Tool inputs are validated

7/14 tool handlers declare input schemas (50%)

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.

Shell command execution

2 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

list_running_vms: description implies read-only but handler writes/deletes/executes; list_snapshots: description implies read-only but handler writes/deletes/executes

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