Universal MCP server that enables any LLM agent (Claude, Cursor, Cline) to control a real Chrome browser with 5 perception engines, resilient heartbeat, and real-time vision streaming.
Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

Install from
M8ven verifies MCPs across every public registry — install directly from whichever one you prefer.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.

HYPERION_EXTENSION_IDTool 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
20/20 tools missing one or more hints — browser_navigate (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); browser_click (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); browser_type (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +17 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.
License file
No license file
Add a LICENSE file (MIT, Apache-2.0, etc.).
Tool test coverage
14/20 tools referenced in tests (70%)
Write tests that reference each tool by name so every tool has at least one test.
Shell command execution
1 child_process/subprocess call in production code — runs shell commands (native-host/install.ts:49)
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Dependency freshness
3/8 production deps abandoned (no release in 2+ years): jpeg-js@2022-10-31 (3.8y), pngjs@2023-02-20 (3.5y), events@2023-07-12 (3.1y)

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.
