WHAT IT DOES

What lazy_add_intersection does on Plugin Hub

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

RISK

Why lazy_add_intersection is rated Medium

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

RECOMMENDED RULE

The rule that runs lazy_add_intersection safely

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

lazy_add_intersection Rate-limited

lazy_add_intersection 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.

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Plugin Hub, apply this rule, and every lazy_add_intersection call is checked against it from then on.

FAQ

Questions about lazy_add_intersection

What does the lazy_add_intersection tool do? +

Add intersection observer loading. It is categorised as a Write tool in the Plugin Hub MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on lazy_add_intersection? +

Register the Plugin Hub MCP server in PolicyLayer and add a rule for lazy_add_intersection: 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 Plugin Hub. Nothing to install.

What risk level is lazy_add_intersection? +

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

Can I rate-limit lazy_add_intersection? +

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

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

lazy_add_intersection is provided by the Plugin Hub MCP server (@barnburner121/plugin-hub-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
