Documentation Overview
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
| Tool | Description |
|---|---|
scan_mcp_config | Scan MCP server configurations for security issues (dangerous commands, exposed secrets, network exposure, container misconfigs) |
detect_prompt_injection | Analyze text for prompt injection attempts across 7 attack categories with context-aware risk scoring |
validate_scope_contract | Check if agent actions comply with scope contracts (tool allowlists, file access, boundary constraints) |
scan_secrets | Detect leaked API keys, tokens, private keys, database URIs, and credentials in text or code |
audit_agent_permissions | Audit agent configurations against role-based expectations and flag principle of least privilege violations |
generate_security_report | Generate comprehensive security assessment reports with prioritized remediation plans |
detect_tool_poisoning | Analyze MCP tool definitions for hidden instructions that could manipulate agent behavior (OWASP Agentic Top 10) |

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
