What is the Beagle Security MCP Server?
Connect your Beagle Security account to any AI agent and take full control of your automated cybersecurity audits and web application penetration testing through natural conversation.
What you can do
- Pentest Orchestration — Programmatically trigger high-fidelity penetration tests for your configured web applications and APIs directly through your agent
- Real-Time Monitoring — Monitor the progress and status of active security tests and retrieve real-time alerts for identified threats
- Vulnerability Intelligence — Access complete high-fidelity vulnerability reports in JSON format and retrieve detailed metadata for every security session
- Application Architecture — List and manage your directory of security projects and applications to maintain a perfectly coordinated audit infrastructure
- Audit Compliance — Access historical records of all past test results and monitor currently running tests to ensure constant security oversight
How it works
- Subscribe to this server
- Retrieve your Access Token (User Settings) and Application Token (Project Settings) from the Beagle Security dashboard
- Start orchestrating your cybersecurity defenses from Claude, Cursor, or any MCP client
No more manual toggling between security scanners or digging through fragmented audit reports. Your AI acts as your dedicated security engineer and penetration testing coordinator.
Who is this for?
- Security Engineers — instantly trigger regression tests and analyze vulnerability patterns using natural language commands
- DevOps Teams — verify application security after a deployment and monitor API health without leaving your workspace
- CISOs & IT Leads — automate the oversight of organization-wide security posture through simple AI queries

Why Cursor?
Cursor's Agent mode turns Beagle Security into an in-editor superpower. Ask Cursor to generate code using live data from Beagle Security and it fetches, processes, and writes. all in a single agentic loop. 9 tools appear alongside file editing and terminal access, creating a unified development environment grounded in real-time information.
- —
Agent mode turns Cursor into an autonomous coding assistant that can read files, run commands, and call MCP tools without switching context
- —
Cursor's Composer feature can generate entire files using real-time data fetched through MCP. no copy-pasting from external dashboards
- —
MCP tools appear alongside built-in tools like file reading and terminal access, creating a unified agentic environment
- —
VS Code extension compatibility means your existing workflow, keybindings, and extensions all work alongside MCP tools

Frequently asked questions
How do I find my Beagle Access and Application Tokens?
Log in to Beagle Security. find the Access Token in your profile/user settings, and the Application Token in the settings of the specific project you want to test.
Can I stop a running test via AI?
Yes! The stop_test tool allows your agent to immediately terminate an active penetration test for the configured application.
How do I retrieve the vulnerability report?
First use get_test_sessions to identify the test's resultToken, then pass that token to get_test_result to retrieve the high-fidelity JSON report.
What is Agent mode and why does it matter for MCP?
Agent mode is Cursor's autonomous execution mode where the AI can perform multi-step tasks: reading files, editing code, running terminal commands, and calling MCP tools. Without Agent mode, Cursor operates in a simpler ask-and-answer mode that doesn't support tool calling. Always ensure you're in Agent mode when working with MCP servers.
Where does Cursor store MCP configuration?
Cursor looks for MCP server configurations in a mcp.json file. You can configure servers at the project level (.cursor/mcp.json in your project root) or globally (~/.cursor/mcp.json). Project-level configs take precedence.
Can Cursor use MCP tools in inline edits?
No. MCP tools are only available in Agent mode through the chat panel. Inline completions and Tab suggestions do not trigger MCP tool calls. This is by design. tool calls require user visibility and approval.
How do I verify MCP tools are loaded?
Open Settings → Features → MCP and look for your server name. A green indicator means the server is connected. You can also check Agent mode's available tools by clicking the tools dropdown in the chat panel.
Tools not appearing in Cursor
Ensure you are in Agent mode (not Ask mode). MCP tools only work in Agent mode.
