Why get_error_history needs a policy

This tool retrieves and queries historical error data without side effects. It performs filtering on existing log information but does not create, modify, delete, or execute any operations. The action is purely informational for monitoring and debugging purposes.

From the tool's definition Tool name 'get_error_history' and description 'Get chronological error history with optional filtering' indicate read-only data retrieval. No modification, deletion, or execution capabilities are described.

POLICY

How to control get_error_history

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

policy.json

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

get_error_history 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 DevServer MCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

Questions about get_error_history

What does the get_error_history tool do? +

Get chronological error history with optional filtering. It is categorised as a Read tool in the DevServer MCP MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on get_error_history? +

Register the DevServer MCP server in PolicyLayer and add a rule for get_error_history: 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 DevServer MCP. Nothing to install.

What risk level is get_error_history? +

Can I rate-limit get_error_history? +

Yes. Add a rate_limit block to the get_error_history 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 get_error_history completely? +

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

get_error_history is provided by the DevServer MCP server (mntlabs/devserver-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every DevServer MCP tool call.

Start from DevServer MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
