What is the Halo Security MCP Server?
Connect your Halo Security platform to any AI agent and take full control of your attack surface and vulnerability management through natural conversation.
What you can do
- Asset Monitoring — List and add targets (domains, IPs, apps) to your security perimeter.
- Vulnerability Oversight — Access and inspect discovered security issues, severities, and remediation status.
- Scan Management — Review scan history and trigger new on-demand security assessments.
- Infrastructure Discovery — List open ports, SSL/TLS certificates, and detected technologies across your assets.
- Security Trends — Retrieve risk scores and security trends to monitor your posture over time.
- DNS Insights — Access DNS records discovered during the reconnaissance phase.
How it works
- Subscribe to this server
- Enter your Halo Security API Key
- Start managing your security posture from Claude, Cursor, or any MCP-compatible client
No more manual exporting of vulnerability reports. Your AI assistant acts as a dedicated Security Analyst or AppSec Specialist.
Who is this for?
- Security Engineers — instantly retrieve asset lists and vulnerability details during triage.
- DevSecOps Teams — automate the triggering of scans and monitoring of security issues in real-time.
- CISOs — maintain a high-level overview of the organization's attack surface and risk scores.

Why CrewAI?
When paired with CrewAI, Halo Security becomes a first-class tool in your multi-agent workflows. Each agent in the crew can call Halo Security tools autonomously, one agent queries data, another analyzes results, a third compiles reports, all orchestrated through Vinkius with zero configuration overhead.
- —
Multi-agent collaboration lets you decompose complex workflows into specialized roles, one agent researches, another analyzes, a third generates reports, each with access to MCP tools
- —
CrewAI's native MCP integration requires zero adapter code: pass Vinkius Edge URL directly in the
mcpsparameter and agents auto-discover every available tool at runtime - —
Built-in task delegation and shared memory mean agents can pass context between steps without manual state management, enabling multi-hop reasoning across tool calls
- —
Sequential and hierarchical crew patterns map naturally to real-world workflows: enumerate subdomains → analyze DNS history → check WHOIS records → compile findings into actionable reports

Frequently asked questions
How do I find my Halo Security API Key?
Log in to your Halo Security account, navigate to Account Settings and then to the API section. You will be able to generate and copy your unique API key from there.
Can I trigger a new scan through this integration?
Yes! Use the trigger_scan tool by providing the unique target ID of the asset you want to assess. Halo Security will initiate the scan immediately.
How are security issues categorized?
Issues are categorized by their severity (e.g., Critical, High, Medium, Low) and type (e.g., Vulnerability, Information, SSL Issue). You can use list_issues to see all findings.
Is it possible to add new domains to monitor?
Yes, the add_target tool allows you to add new domains or IP addresses to your security perimeter directly from the AI agent.
How does CrewAI discover and connect to MCP tools?
CrewAI connects to MCP servers lazily. when the crew starts, each agent resolves its MCP URLs and fetches the tool catalog via the standard tools/list method. This means tools are always fresh and reflect the server's current capabilities. No tool schemas need to be hardcoded.
Can different agents in the same crew use different MCP servers?
Yes. Each agent has its own mcps list, so you can assign specific servers to specific roles. For example, a reconnaissance agent might use a domain intelligence server while an analysis agent uses a vulnerability database server.
What happens when an MCP tool call fails during a crew run?
CrewAI wraps tool failures as context for the agent. The LLM receives the error message and can decide to retry with different parameters, fall back to a different tool, or mark the task as partially complete. This resilience is critical for production workflows.
Can CrewAI agents call multiple MCP tools in parallel?
CrewAI agents execute tool calls sequentially within a single reasoning step. However, you can run multiple agents in parallel using process=Process.parallel, each calling different MCP tools concurrently. This is ideal for workflows where separate data sources need to be queried simultaneously.
Can I run CrewAI crews on a schedule (cron)?
Yes. CrewAI crews are standard Python scripts, so you can invoke them via cron, Airflow, Celery, or any task scheduler. The crew.kickoff() method runs synchronously by default, making it straightforward to integrate into existing pipelines.
MCP tools not discovered
Ensure the Edge URL is correct. CrewAI connects lazily when the crew starts. check console output.
Agent not using tools
Make the task description specific. Instead of "do something", say "Use the available tools to list contacts".
Timeout errors
CrewAI has a 10s connection timeout by default. Ensure your network can reach the Edge URL.
Rate limiting or 429 errors
Vinkius enforces per-token rate limits. Check your subscription tier and request quota in the dashboard. Upgrade if you need higher throughput.
