Solutions · Protect MCP and Tools

Know every MCP server and tool your agents can call, and decide each call before it runs

The Model Context Protocol makes it easy to give agents new tools, and just as easy to give them tools nobody reviewed. CydraLabs discovers MCP servers and their tools, authenticates the agents calling them and evaluates policy for each tool call.

The challenge

What teams tell us they face

For: Platform engineering, AI engineering and application security teams

  • MCP servers are added by individual teams and rarely appear in an asset inventory.
  • Tool descriptions and responses can carry instructions that steer an agent (tool poisoning).
  • Agents often reach MCP servers with shared or long-lived credentials.
  • A single compromised server can expose every tool and data source behind it.

The approach

How CydraLabs helps

  1. Step 1

    Discover servers and tools

    Enumerate MCP servers and their tools through the MCP tools/list interface, with SSRF safeguards (Beta).

  2. Step 2

    Authenticate the caller

    Each agent presents a signed, short-lived workload token; unknown or suspended agents are denied.

  3. Step 3

    Decide per tool call

    Policy over agent, tool, operation, target, data classification and risk decides allow, deny or require approval.

  4. Step 4

    Inspect and record

    Parameters are checked for secrets, personal data and injection patterns; every decision becomes evidence.
