AI agents call get_execution_result to retrieve information from Lens without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
execution_id | string | Yes | Workflow execution UUID |
Parameters from the server's own tool schema.
This tool queries and retrieves the result of a previously executed workflow using an execution ID. It performs no data modification, deletion, or external operation triggering—it simply fetches and returns information about a past execution. This is a straightforward Read operation with minimal risk.
From the tool's definition Tool name 'get_execution_result' and description 'Get the result of a workflow execution by its execution_id' both indicate a retrieval operation.
Attacks that exploit this kind of access
Get the result of a workflow execution by its execution_id. It is categorised as a Read tool in the Lens MCP Server, which means it retrieves data without modifying state.
get_execution_result accepts 1 parameter: execution_id. Required: execution_id. The full parameter table on this page comes from the server's own tool schema.
Register the Lens MCP server in PolicyLayer and add a rule for get_execution_result: 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 Lens. Nothing to install.
get_execution_result 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 get_execution_result 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 get_execution_result. 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.
get_execution_result is provided by the Lens MCP server (lens-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
