How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →

- 100% of tool parameters carry a description.Pass
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass

Provenance No attestation
The registry publishes no build provenance for this version, so there is nothing to verify.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
attach Attach to a page ~131
Connect to a WebView page and start buffering its console output and uncaught exceptions (the last 1000 entries). Recent messages the engine still holds are replayed on attach, but attach before reproducing an issue to be sure nothing is missed. Only observes the page: it is not reloaded or modified. May be refused while Chrome DevTools (chrome://inspect) is attached to the same page; close it and retry. Calling it again for an attached page reuses the existing session.
| Name | Type | Req | Description |
|---|---|---|---|
| target_id | string | yes | Target id from list_targets, e.g. "<serial>/<socket>/<page id>" |
No output schema declared.
No examples provided.
detach Detach from a page ~64
Disconnect from a page and discard its buffered console entries. The page itself keeps running and is not closed; call attach again to resume capturing. Use it to stop capturing or to start over with an empty buffer.
| Name | Type | Req | Description |
|---|---|---|---|
| target_id | string | – | Defaults to the most recently attached page |
No output schema declared.
No examples provided.
evaluate_js Evaluate JavaScript in a page ~130
Run a JavaScript expression in an attached page and return its result. Plain objects/arrays come back as JSON (so nested Map/Set/DOM values show as {}); other values (DOM nodes, Map, Set, Error, window) as a short description. Promises are awaited. For multiple statements or await, wrap them: (async () => { ... })(). Runs with the page's full privileges, so it can read cookies/storage and change page state.
| Name | Type | Req | Description |
|---|---|---|---|
| expression | string | yes | JavaScript expression to evaluate |
| target_id | string | – | Defaults to the most recently attached page |
No output schema declared.
No examples provided.
get_console Read console output ~179
Read buffered console messages, uncaught exceptions and browser log entries from an attached page. Requires attach first; only entries captured since attach (plus what attach replayed) are available. Returns the most recent matching entries. Pass since_seq from a previous call to get only new entries.
| Name | Type | Req | Description |
|---|---|---|---|
| exclude_keywords | array | – | Drop entries whose text or location contains any of these (case-insensitive), e.g. ["google-analytics", "doubleclick"] |
| keyword | string | – | Case-insensitive substring match on message text and location |
| levels | array | – | Only these levels, e.g. ["warn", "error"] |
| limit | integer | – | Max entries to return (default 50) |
| since_seq | integer | – | Only entries with seq greater than this |
| target_id | string | – | Defaults to the most recently attached page |
No output schema declared.
No examples provided.
list_targets List WebView pages ~40
List debuggable H5 pages running inside Android WebViews (and Chrome) on connected devices. Returns a target id for each page to pass to attach.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
