console-stream-mcp (Topman-14/mobius-mcp) is an MCP server listed on the M8ven Trust Index. M8ven has not graded it: we have no way to read this server ourselves. The publisher has confirmed an email address for this listing, which proves an inbox rather than ownership (Claimed).
Enables AI coding agents to access live console logs, errors, and network requests from web applications via a local WebSocket connection, without copying data to chat.
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.

Connect your repo and M8ven re-verifies it on the push itself. Without it we re-check verified listings about once a day, so a fix can sit unseen. Read-only, one click, revoke anytime. What we access →
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.
@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
ws: Memory exhaustion DoS from tiny fragments and data chunks

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
46/46 tools missing one or more hints — mobius_diagnose (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_recent_logs (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_recent_errors (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +43 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
Only 2/46 tools referenced in tests (4%)
Write tests that reference each tool by name so every tool has at least one test.
Production dependencies are patched
0 critical, 4 high severity in production deps — @modelcontextprotocol/sdk@1.12.0 (high), @modelcontextprotocol/sdk@1.12.0 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
