claude-nexus (skyvanguard/claude-nexus) is an MCP server listed on the M8ven Trust Index. M8ven has not graded it: we have no way to read this server ourselves. No publisher has claimed this listing.
Enables Claude Code instances to discover each other and exchange messages instantly via a local broker and channel protocol. Supports scoped peer discovery, reliable ack-based delivery, and cross-platform operation.
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.

Optional human-readable names via .OPENAI_API_KEYSet and each instance generates a one-line summary on startup usingTool 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
10/10 tools missing one or more hints — list_peers (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); send_message (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); set_summary (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +7 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 test coverage
Only 2/10 tools referenced in tests (20%)
Write tests that reference each tool by name so every tool has at least one test.
Shell command execution
13 child_process calls — runs shell commands
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Secrets not logged
1 secret value sent to console.log
Redact or omit secret values from log output.
