Install

Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

NPM package agent-security-mcp
Claude Code 
claude mcp add agent-security -- npx -y agent-security-mcp@0.1.3
JSON configuration (Claude Desktop, Cursor, VS Code) 
{
    "mcpServers": {
        "agent-security": {
            "command": "npx",
            "args": [
                "-y",
                "agent-security-mcp@0.1.3"
            ]

Agent Security MCP Server

Security scanning, prompt injection detection, secret leak detection, and agent permission auditing for AI agent workflows. Built on the Model Context Protocol (MCP).

Tools

ToolDescription
scan_mcp_configScan MCP server configurations for security issues (dangerous commands, exposed secrets, network exposure, container misconfigs)
detect_prompt_injectionAnalyze text for prompt injection attempts across 7 attack categories with context-aware risk scoring
validate_scope_contractCheck if agent actions comply with scope contracts (tool allowlists, file access, boundary constraints)
scan_secretsDetect leaked API keys, tokens, private keys, database URIs, and credentials in text or code
audit_agent_permissionsAudit agent configurations against role-based expectations and flag principle of least privilege violations
generate_security_reportGenerate comprehensive security assessment reports with prioritized remediation plans
detect_tool_poisoningAnalyze MCP tool definitions for hidden instructions that could manipulate agent behavior (OWASP Agentic Top 10)

Installation

cd agent-security-mcp
npm install

Usage

As a standalone server
npm start
In Claude Desktop / MCP client configuration
{
  "mcpServers": {
    "agent-security": {
      "command": "node",
      "args": ["/path/to/agent-security-mcp/src/index.js"]
    }
  }
}
With npx (after publishing)
{
  "mcpServers": {
    "agent-security": {
      "command": "npx",
      "args": ["@asl-throne/agent-security-mcp"]
    }
  }
}

Detection Coverage

Prompt Injection (7 categories, 20+ patterns)
  • Instruction Override -- "ignore previous instructions", "disregard all rules", "new instructions:"
  • Identity Manipulation -- "you are now", "pretend you are", "act as", DAN/jailbreak
  • System Prompt Extraction -- "repeat your system prompt", "show your instructions"
  • Data Exfiltration -- "send this to", "post to webhook", "email everything to"
  • Delimiter Attacks -- \\\`system, [INST], <|im_start|>system, XML tag injection
  • Encoded Injection -- Base64 payloads, unicode zero-width characters, hex escapes
  • Privilege Escalation -- "sudo mode", "disable safety", "bypass filters"
Secret Detection (25+ patterns)
  • AI Provider Keys -- OpenAI (sk-), Anthropic (sk-ant-)
  • Cloud Credentials -- AWS (AKIA*), GCP (AIza*), Azure connection strings
  • Source Control -- GitHub PATs (ghp_*, github_pat_*), OAuth tokens (gho_*)
  • Payment -- Stripe live/test keys (sk_live_*, sk_test_*)
  • Communication -- Slack tokens/webhooks, Telegram bot tokens
  • Database -- PostgreSQL, MongoDB, MySQL, Redis connection URIs
  • Cryptographic -- RSA/EC/OpenSSH private keys, generic PEM blocks
  • JWT -- JSON Web Tokens
  • Generic -- api_key=, secret=, password=, .env file patterns
Permission Audit (6 role profiles)
  • Researcher -- Read + search + web only
  • Analyst -- Read + search only
  • Developer -- Read + write + execute
  • Reviewer -- Read only, no network
  • Orchestrator -- Read + write + task spawning
  • Monitor -- Read only, no network, no write
