Why validate_config needs a policy

Validation of configuration files is fundamentally a read operation—it parses and checks a file against a schema to report errors, with no side effects, data modification, code execution, or deletion. This is a safe, informational tool with minimal blast radius if misused.

From the tool's definition Tool description states it 'Validate[s] a .techdebtrc.json configuration file for syntax and schema correctness.' Validation is a read-only operation that checks structure and syntax without modifying files or triggering code execution.

POLICY

How to control validate_config

PolicyLayer is an MCP gateway — it sits between your AI agents and Tech Debt MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for validate_config:

policy.json

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

validate_config is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Tech Debt MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about validate_config

What does the validate_config tool do? +

Validate a .techdebtrc.json configuration file for syntax and schema correctness. It is categorised as a Read tool in the Tech Debt MCP Server MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on validate_config? +

Register the Tech Debt MCP Server MCP server in PolicyLayer and add a rule for validate_config: 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 Tech Debt MCP Server. Nothing to install.

What risk level is validate_config? +

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

Can I rate-limit validate_config? +

Yes. Add a rate_limit block to the validate_config 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_config completely? +

Set action: deny in the PolicyLayer policy for validate_config. 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_config? +

validate_config is provided by the Tech Debt MCP Server MCP server (pierrejanineh/techdebtmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
