claude-c2 (0xyg3n/claude-c2) 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 natural language command and control of remote systems across multiple platforms through Claude AI using the Model Context Protocol.
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.
@modelcontextprotocol/sdk has cross-client data leak via shared server/transport instance reuse
Anthropic's MCP TypeScript SDK has a ReDoS vulnerability
express-rate-limit: IPv4-mapped IPv6 addresses bypass per-client rate limiting on servers with dual-stack network
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
94/94 tools missing one or more hints — list_clients (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); client_info (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); shell (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +91 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.).
Tests exist
No test files found
Add tests that exercise each declared tool.
Secrets not logged
3 secret values sent to console.log
Redact or omit secret values from log output.
Production dependencies are patched
0 critical, 4 high severity in production deps — @modelcontextprotocol/sdk@1.24.3 (high), @modelcontextprotocol/sdk@1.24.3 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
