AI agents call describe_live_connector to retrieve information from Flow Studio - Power Automate MCP Server without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though describe_live_connector only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

These attack patterns abuse exactly the kind of access describe_live_connector gives an agent. Each links to the full case and the policy that stops it:
Other read tools across the catalogue. The same approach applies to each: allow, with a rate cap to control cost.
Describe a live Power Platform connector/API and its operations. Aligned with Canvas MCP describe_api. Use mode=summary (default) to get a compact operation catalog. Use operationId to describe one operation, including inputs, outputs, dynamic parameter metadata, nextTool hints to call get_live_dynamic_options, and an authored hint + canonical example shape (when one exists) to copy into update_live_flow. Use search without connectorName/apiName to search operations across connectors and get connection-aware suggestions. Use mode=full only when raw OpenAPI connector metadata is required.. It is categorised as a Read tool in the Flow Studio - Power Automate MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Flow Studio - Power Automate MCP Server MCP server in PolicyLayer and add a rule for describe_live_connector: 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 Flow Studio - Power Automate MCP Server. Nothing to install.
describe_live_connector is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the describe_live_connector 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.
Set action: deny in the PolicyLayer policy for describe_live_connector. 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.
describe_live_connector is provided by the Flow Studio - Power Automate MCP Server MCP server (https://mcp.flowstudio.app/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
