THE RISK

Low Risk

Why query-records needs a policy

This tool performs a read-only operation that retrieves records from Dataverse using OData filters. Query operations are non-destructive and do not modify, delete, or execute arbitrary code. The tool is limited to data retrieval, making it a Read category risk with low severity since it only exposes existing data without ability to alter system state.

From the tool's definition Tool name 'query-records' and description 'Query records using an OData filter expression' indicate retrieval/querying of data with no side effects mentioned.

POLICY

How to control query-records

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "query-records": {}
  }
}

query-records 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 PowerPlatform MCP — 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 query-records

What does the query-records tool do? +

Query records using an OData filter expression. It is categorised as a Read tool in the PowerPlatform MCP MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on query-records? +

Register the PowerPlatform MCP server in PolicyLayer and add a rule for query-records: 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 PowerPlatform MCP. Nothing to install.

What risk level is query-records? +

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

Can I rate-limit query-records? +

Yes. Add a rate_limit block to the query-records 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 query-records completely? +

Set action: deny in the PolicyLayer policy for query-records. 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 query-records? +

query-records is provided by the PowerPlatform MCP server (michsob/powerplatform-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every PowerPlatform MCP tool call.

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