Gsep tools (6, 1 write)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

  • gsep_chatwrite action

    Send a message through the full GSEP pipeline. Runs C3 prompt injection scan, enhanced LLM call with evolved genes, C4 behavioral immune check, C5 action firewall, fitness tracking, and autonomous evolution. Returns the protected response.

  • gsep_get_status

    Get genome health, fitness scores, drift status, evolution generation, and security stats. Omit genome_id to list all active genomes.

  • gsep_record_feedback

    Record user satisfaction feedback for a genome. Positive signals reinforce current gene configuration. Negative signals trigger evolution on the next cycle.

  • gsep_scan_actions

    Scan LLM response for dangerous or destructive actions with C5 Action Firewall (80+ patterns). Classifies actions as safe/caution/destructive/critical. Permanently blocks rm -rf, DROP DATABASE, disk wipes, etc.

  • gsep_scan_input

    Scan user input with C3 Content Firewall (53 patterns). Detects prompt injection, role hijacking, data exfiltration attempts, encoding evasion, and more. Use this before sending any external content to your LLM.

  • gsep_scan_output

    Scan LLM output with C4 Behavioral Immune System (6 checks). Detects if the response was infected by Indirect Prompt Injection — system prompt leakage, role confusion, data exfiltration patterns, and more.

Install Gsep in Claude Code, Cursor or VS Code

Runs npx -y @gsep/mcp on your machine. Read the scan report first; the gateway never runs local packages.

GSEP-MCP — AI Agent Security via Model Context Protocol

The only MCP server that protects your AI agent instead of just extending it.

At a Glance

What is GSEP-MCP?

There are 9,400+ MCP servers. All of them give your agent new tools — Notion, GitHub, Slack, databases.

GSEP-MCP is different. It gives your agent security, safety, and self-improvement — without writing a single line of code.

Works with: Claude Desktop, Cursor, Windsurf, Cline, Continue, n8n, Make, any MCP client.

Integrations

GSEP-MCP supports two transports: stdio (for desktop apps and IDEs) and HTTP (for servers, backends, and automation platforms). Pick the one that matches your environment.

stdio Transport (Desktop / IDE)

stdio is the simplest transport. The MCP client launches GSEP-MCP as a subprocess and communicates via stdin/stdout. No port, no server, no network.

Claude Desktop

Add to ~/Library/Application Support/Claude/claudedesktopconfig.json:

{
  "mcpServers": {
    "gsep": {
      "command": "npx",
      "args": ["-y", "@gsep/mcp"],
      "env": {
        "ANTHROPIC_API_KEY": "sk-ant-..."
      }
    }
  }
}

Restart Claude Desktop. Your agent is now protected.

Cursor

Add to .cursor/mcp.json in your project (or global ~/.cursor/mcp.json):

{
  "mcpServers": {
    "gsep": {
      "command": "npx",
      "args": ["-y", "@gsep/mcp"],
      "env": {
        "ANTHROPIC_API_KEY": "sk-ant-..."
      }
    }
  }
}

Windsurf

Add to ~/.codeium/windsurf/mcp_config.json:

{
  "mcpServers": {
    "gsep": {
      "command": "npx",
      "args": ["-y", "@gsep/mcp"],
      "env": {
        "ANTHROPIC_API_KEY": "sk-ant-..."
      }
    }
  }
}

Cline / Continue / Any MCP-compatible IDE

Add the same config block to your IDE's MCP settings file. GSEP-MCP is compatible with any client that implements the MCP protocol.

OpenClaw / Genome

{
  "mcpServers": {
    "gsep": {
      "command": "npx",
      "args": ["-y", "@gsep/mcp"],
      "env": {
        "ANTHROPIC_API_KEY": "sk-ant-...",
        "GSEP_PRESET": "full"
      }
    }
  }
}
