Check the connection status of the Chrome extension bridge to your logged-in Chrome, so you can confirm browser automation is available before running tasks.

Changes observed during successful MCP inspections.
v1.1.0Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint, so the safety profile is covered structurally. The description adds the useful clarification that the status refers to the real logged-in Chrome bridge rather than a headless browser, but says nothing about what the reported status looks like or failure modes.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
A single front-loaded sentence with no filler; the essential identifying information comes first.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a no-argument status probe with no output schema, the description leaves the return values (e.g., connected/disconnected, extension version) entirely unspecified, which is the one remaining gap an agent would care about.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Zero parameters and 100% schema coverage, so there is nothing for the description to disambiguate. Baseline 4 applies.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
It names a specific resource (the Chrome extension bridge connection) and clarifies that the bridge targets the user's real, logged-in Chrome, so an agent can tell it apart from browser_* or chrome_* action tools. It stops short of explicitly contrasting itself with the neighboring chrome_pairing_setup / chrome_extension_reload tools.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description never says when to call this versus alternatives, whether it must be checked before other chrome_* calls, or what a negative result implies. The read-only diagnostic nature is only implied.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
