// key findings

⚠️

Tool descriptions don’t match what handlers do

2 tools describe read intent but their handlers mutate — text_to_speech (line 114: with open(output_path / output_file_name, "wb") as f:); text_to_sound_effects (line 208: with open(output_path / output_file_name, "wb") as f:)

✅

No credential exfiltration, no sensitive file access, no obfuscation

Static analysis found nothing flowing your secrets to unexpected places.

✅

Open source with a license and README

Anyone can audit the code, the license is declared, and the publisher documents what it does.

🔐

You'll be asked for 1 credential: ELEVENLABS_API_KEY

These are read from process.env at runtime. Make sure you trust where they’ll be sent.

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

65/65 tools missing one or more hints — get_session_info (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_track_info (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); create_midi_track (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +62 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

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

Tool inputs are validated

57/65 tool handlers declare input schemas (88%)

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

Tool handlers catch errors

44/65 tool handlers wrap calls in try/catch (68%)

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

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.
