WHAT IT DOES

What validate_code does on ContextForge MCP Gateway

AI agents call validate_code 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_code is rated Low

This tool performs static analysis or linting of Python code. It retrieves information about code validity without modifying data, executing code, or triggering external operations. The explicit constraint 'without executing it' confirms no Execute-category risk applies. This is a safe, read-only operation suitable for code quality checks.

From the tool's definition Tool name is 'validate_code' and description explicitly states 'Validate Python code without executing it' — validation is a read-only inspection operation that parses and checks code for syntax or semantic errors without side effects.

RECOMMENDED RULE

The rule that runs validate_code 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_code, this is the rule to start with:

validate_code Allowed

validate_code 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_code": {}
  }
}

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_code call is checked against it from then on.

FAQ

Questions about validate_code

What does the validate_code tool do? +

Validate Python code without executing it. It is categorised as a Read tool in the ContextForge MCP Gateway MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on validate_code? +

Register the ContextForge MCP Gateway MCP server in PolicyLayer and add a rule for validate_code: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches ContextForge MCP Gateway. Nothing to install.

What risk level is validate_code? +

validate_code is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit validate_code? +

Yes. Add a rate_limit block to the validate_code rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block validate_code completely? +

Set action: deny in the PolicyLayer policy for validate_code. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides validate_code? +

validate_code is provided by the ContextForge MCP Gateway MCP server (jrmatherly/mcp-context-forge). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
