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 — open_shell (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); run_command (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); close_shell (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.
Descriptions match behaviour
1 tool describes read intent but its handler mutates — get_browser_history (line 203: shutil.copy(chrome_db, "/tmp/History_copy"))
Rename the tool, rewrite the description, or move the side-effect into a separate clearly-named tool.
Tool inputs are validated
15/16 tool handlers declare input schemas (94%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
9/16 tool handlers wrap calls in try/catch (56%)
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.
No access to sensitive paths
Reads sensitive paths: oauth_credentials.json
Remove reads of sensitive system paths. If you genuinely need them, document why in the README.
Tool description accuracy
get_browser_history: 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.
