MCP server that lets AI coding tools control and observe a running Node.js process through the chrome devtools protocol (CDP), via a lightweight Debug Adapter Protocol (DAP) bridge.
Emerging. No concerning findings. Grades remain capped until the project builds reputation through adoption. 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.
DAP_VERBOSE[Verbose diagnostics ()](#verbose-diagnostics-dap_verbose)MCP_CDP_ALLOW_REMOTE1 to enable unset Allow attach to non-loopback hosts. Only the exact value 1 enables it; a stderr warning is printed at startup while set. See [Security model](#security-model).MCP_LOGPOINT_BUFFER_SIZEpositive integer 2000 FIFO buffer size for logpoint hits and debugger events. Non-numeric or non-positive values fall back to the default.MCP_TEST_APP_PORTTool 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
31/31 tools missing one or more hints — attach (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); disconnect (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); setBreakpoints (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +28 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 inputs are validated
Only 15/31 tool handlers declare input schemas (48%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
Only 3/31 tool handlers wrap calls in try/catch (10%)
Wrap each tool handler body in try/catch and return a structured error response.
Tool test coverage
22/31 tools referenced in tests (71%)
Write tests that reference each tool by name so every tool has at least one test.
No eval / new Function
5 eval() or new Function() calls — dynamic code execution
Replace eval / Function with explicit parsing or safer alternatives.
Shell command execution
1 child_process call — runs shell commands
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
