WHAT IT DOES

What auto does on A2a Cloud

AI agents use auto to create or update resources in A2a Cloud, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your A2a Cloud environment.

RISK

Why auto is rated Medium

An AI agent can call auto faster than any human can review: one bad instruction and it creates or modifies resources in A2a Cloud by the hundred, each call as confident as the last.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs auto safely

PolicyLayer is an MCP gateway: it sits between your AI agents and A2a Cloud, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For auto, this is the rule to start with:

auto Rate-limited

auto stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about auto

What does the auto tool do? +

Use the OpenAPI service to complete a natural-language goal. It is categorised as a Write tool in the A2a Cloud MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on auto? +

Register the A2a Cloud MCP server in PolicyLayer and add a rule for auto: 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 A2a Cloud. Nothing to install.

What risk level is auto? +

auto is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit auto? +

Yes. Add a rate_limit block to the auto 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 auto completely? +

Set action: deny in the PolicyLayer policy for auto. 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 auto? +

auto is provided by the A2a Cloud MCP server (robGetsTheJobDone/a2a-cloud). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
