WHAT IT DOES

What validate_graph does on ContextForge MCP Gateway

AI agents call validate_graph to retrieve information from ContextForge MCP Gateway without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why validate_graph is rated Low

Validating DOT file syntax is a purely analytical/read operation: it inspects input and reports whether it conforms to the DOT format specification. No data is created, modified, deleted, or executed. Blast radius is minimal since misuse would at worst return incorrect validation results.

From the tool's definition 'Validate DOT file syntax' — validation is a read/check operation with no side effects

RECOMMENDED RULE

The rule that runs validate_graph safely

PolicyLayer is an MCP gateway: it sits between your AI agents and ContextForge MCP Gateway, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For validate_graph, this is the rule to start with:

validate_graph Allowed

validate_graph is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "validate_graph": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect ContextForge MCP Gateway, apply this rule, and every validate_graph call is checked against it from then on.
