Security Report
5.7
Moderate5.7Moderate RiskThis is a well-intentioned MCP server for agent diagnostics and skill file delivery with reasonable auth controls and appropriate permissions for its purpose. However, there are some code quality concerns and a moderate risk related to environment variable handling for sensitive credentials (Stripe keys, webhook secrets). The server's core functionality is sound, but deployment security depends heavily on proper environment variable management. Supply chain analysis found 2 known vulnerabilities in dependencies (0 critical, 1 high severity).

Agentic Platform
The only MCP linter that exists. Plus free governance scoring and cost estimation for AI agents.
Validate your MCP tool definitions, score your agent's system prompt on governance best practices (0-100), and compare costs across all major models. No API key needed.
Installation
Remote MCP Server (Hosted)
Add to your MCP client configuration:
{
"mcpServers": {
"agentic-platform": {
"url": "https://platform.crestsystems.ai/mcp"
}
}
}
Claude Code
claude mcp add agentic-platform --transport http https://platform.crestsystems.ai/mcp
Docker
docker run -p 8080:8080 ghcr.io/andysalvo/agentic-platform:latest
Works with Claude Desktop, Claude Code, VS Code, Cursor, Cline, and any MCP-compatible client.

Governance
This platform operates under three core invariants:
- No Silent Inference -- no inferring or reinterpreting input without explicit documentation
- Auditability at the Decision Level -- every state change traceable to a decision
- Explicit Authority Transfer -- all commitments require explicit authorization
These apply to the platform itself, not just its users.
