THE RISK

Low Risk

Why search-workflows needs a policy

This tool retrieves and searches workflow metadata without executing, modifying, or deleting any workflows. It performs a read-only query operation that returns information about existing workflows. No side effects or state changes occur from using this tool.

From the tool's definition Tool name 'search-workflows' and description 'Search workflows...by name, entity, description, category, or state' indicate a query/retrieval operation with no modification or execution of workflows.

POLICY

How to control search-workflows

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 search-workflows:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "search-workflows": {}
  }
}

search-workflows 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 search-workflows

What does the search-workflows tool do? +

Search workflows (both classic workflows and Power Automate flows) by name, entity, description, category, or state. 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 search-workflows? +

Register the PowerPlatform MCP server in PolicyLayer and add a rule for search-workflows: 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 search-workflows? +

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

Can I rate-limit search-workflows? +

Yes. Add a rate_limit block to the search-workflows 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 search-workflows completely? +

Set action: deny in the PolicyLayer policy for search-workflows. 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 search-workflows? +

search-workflows 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.
