Blowback
Integrates front-end development servers with AI tools, enabling browser automation, console log capture, screenshot management, and HMR event monitoring.
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.

The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
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.
how-to-useDescription of how to use the server
start-browserCreates a new browser context with an auto-generated unique ID
list-browsersLists all active browser instances
close-browserCloses a specific browser instance
get-context-infoGets detailed information about a specific browser instance
get-context-statsGets usage statistics for browsers
capture-screenshotCaptures a screenshot of the current page or a specific element. Stores the screenshot in the MCP resource system and returns a resource URI. If ENABLE_BASE64 environment variable is set to 'true', also includes base64 encoded image in the response.
get-element-propertiesRetrieves properties and state information of a specific element
get-element-stylesRetrieves style information of a specific element
get-element-dimensionsRetrieves dimension and position information of a specific element
monitor-networkMonitors network requests in the browser for a specified duration
get-element-htmlRetrieves the HTML content of a specific element and its children with optional depth control
get-console-logsRetrieves console logs from the development server
execute-browser-commandsExecutes a sequence of predefined browser commands safely. Available commands: - click: Clicks on an element matching the selector or at specified coordinates - type: Types text into an input element - wait: Waits for an element, a specified time period, or a condition - navigate: Navigates to a sp…
browser-evaluateEvaluates JavaScript code directly in the browser context and returns the result. Supports expressions, function strings, and complex code with automatic execution handling. Can target the entire page or work with element handles for precise DOM manipulation. Examples: - Simple expression: "documen…
get-hmr-eventsRetrieves recent HMR events
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
@modelcontextprotocol/sdk has cross-client data leak via shared server/transport instance reuse
Anthropic's MCP TypeScript SDK has a ReDoS vulnerability
Model Context Protocol (MCP) TypeScript SDK does not enable DNS rebinding protection by default
Playwright downloads and installs browsers without verifying the authenticity of the SSL certificate

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
16/16 tools missing one or more hints — how-to-use (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); start-browser (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list-browsers (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +13 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.
Tool handlers catch errors
15/16 tool handlers wrap calls in try/catch (94%)
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.
No eval / new Function
1 eval() or new Function() call — dynamic code execution
Replace eval / Function with explicit parsing or safer alternatives.
Shell command execution
3 child_process calls — runs shell commands
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Production dependencies are patched
0 critical, 6 high severity in production deps — @modelcontextprotocol/sdk@1.16.0 (high), @modelcontextprotocol/sdk@1.16.0 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.

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.
