MCP Server Security
Inventory every Model Context Protocol server your agents talk to, score the permission risk of each exposed tool, and test for the agentic attack vectors in the OWASP Agentic Top 10.

The gap MCP security closes
MCP servers expose tools to LLM agents with permissions that often exceed what any single user holds. A poisoned tool result, a confused-deputy attack, or excessive agency on a destructive tool can chain into a production incident the SIEM cannot see.
How Penaxtra delivers MCP security
Penaxtra catalogues MCP servers as a first-class asset kind. Each server links to its declared tool surface, the agents that consume it, and the OWASP Agentic Top 10 risk scores per tool. Adversarial probes test for tool-poisoning, indirect injection via tool output, excessive agency, and confused-deputy patterns.
