List all jobs
AI agents call list_jobs to retrieve information from Gmail MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves job information for inspection purposes only. It has no side effects, does not trigger job execution, and does not modify data. The blast radius is minimal—an AI agent using this tool can only view existing job records, which aligns with the lowest severity classification.
From the tool's definition Tool name 'list_jobs' combined with description 'List all jobs' indicates a retrieval operation that queries job status without modifying or executing anything.

List all jobs. It is categorised as a Read tool in the Gmail MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Gmail MCP Server MCP server in PolicyLayer and add a rule for list_jobs: 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 Gmail MCP Server. Nothing to install.
list_jobs 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 list_jobs 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 list_jobs. 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.
