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.

run_shell

Run a PowerShell command on the user's machine.

git

Run a git command. args = e.g. 'status', 'log --oneline -10', 'commit -m "fix bug"'

read_file

Read the contents of a file on the user's machine.

write_file

Write or overwrite a file on the user's machine. After writing code, use run_file to execute it — do NOT also call run_code with the same code.

list_dir

List files and folders in a directory.

edit_file

Edit a file by replacing old_text with new_text. Use this to fix errors instead of rewriting the whole file.

run_file

Run an already-existing file. Use this after write_file — avoids writing the code twice. Language is auto-detected from extension if not provided.

run_code

Execute a code snippet directly without saving to disk. Use for quick one-off runs. If you already wrote the code with write_file, use run_file instead to avoid writing twice. Supported: python, javascript, typescript, java, cpp, csharp, go, rust, ruby, php, r, kotlin, swift, matlab

run_python

Execute Python code directly and return the output.

run_cpp

Compile and run C++ code. Returns compiler errors or program output.

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

10/10 tools missing one or more hints — run_shell (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); git (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); read_file (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +7 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.

Destructive tools are labelled

2 tools perform destructive updates without destructiveHint — run_file deletes at line 210 (try: os.unlink(exe)); run_code deletes at line 294 (if src: os.unlink(src))

Add destructiveHint:true to any tool whose handler calls .delete(), .upsert(), .update(), unlink, rm, DELETE, DROP, REPLACE INTO, or any operation that overwrites existing data.

Tool handlers catch errors

8/10 tool handlers wrap calls in try/catch (80%)

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.

// full audit trail
The findings above are the summary. The full trail, every check we ran, each deduction, the network hosts observed and the dependency advisories, goes to verified publishers, along with an alert whenever a new one lands. Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.
// improvement guidance — verified publishers only
We have 6 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
