GraphPilot gives coding agents persistent structural knowledge of a codebase. It parses TypeScript/JavaScript with tree-sitter into a graph of symbols and call edges, then exposes that graph over MCP so the agent can recall definitions, find callers, and trace change impact without re-reading files every conversation. Local-first: no network, no telemetry, no code ever leaves your machine. Four tools — gp_index, gp_recall, gp_callers, gp_impact.

Security scanner MCP server that protects AI coding agents from generating vulnerable code. Uses tree-sitter AST analysis to detect OWASP Top 10 vulnerabilities, hardcoded secrets, and prompt injection attacks. Includes package hallucination detection across 4.3M packages (npm, PyPI, RubyGems, crates.io, pub.dev, CPAN, Raku). Works with Claude Desktop, Claude Code, Cursor, Cline, and any MCP-compatible client. Full feature list (for detailed descriptions): • 275+ security rules covering Python, JavaScript, TypeScript, Java, Go, Ruby, PHP, C/C++, Rust, C#, Terraform, Kubernetes • AST-based detection with tree-sitter (falls back to regex when unavailable) • Taint analysis for tracking user input to dangerous sinks • Package hallucination detection: verifies 4.3M+ packages across 7 ecosystems • Prompt injection detection: blocks exfiltration, jailbreaks, and malicious instructions • Automatic fix suggestions for common vulnerabilities • Zero config: works instantly with npx • CWE/OWASP metadata for compliance reporting

Superjolt is a Platform-as-a-Service (PaaS) that enables developers to deploy JavaScript applications instantly with a single command: npx superjolt deploy. Through its native Model Context Protocol (MCP) integration, developers can manage their entire deployment infrastructure using natural language via Claude Desktop. Instead of memorizing CLI commands or navigating complex dashboards, you can simply tell Claude what you want: "Show me all my running services," "Restart the API service," or "Set the database URL for production." Superjolt handles the complexities of deployment including automatic HTTPS, environment variables, real-time logs, and service management. The MCP integration transforms infrastructure management from a technical task into a conversation. Claude can access your deployment state, understand your infrastructure context, and execute complex workflows through simple commands. Whether you're deploying a new application, troubleshooting issues, or managing multiple environments, the MCP server provides Claude with the tools to list machines and services, start/stop/restart applications, manage environment variables, view logs, and handle the entire deployment lifecycle. This makes Superjolt ideal for developers who want to focus on building rather than configuring, offering the simplicity of serverless with the power of a full deployment platform—all controlled through natural language.
