Updates dependencies in the lock file. Optionally updates a single package.
AI agents use update to create or update resources in Make — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Make environment.
This tool modifies lock files (package dependency manifests) which are critical infrastructure files. While reversible (can be rolled back or re-run), it affects the entire dependency graph of a project and could introduce breaking changes, security vulnerabilities, or incompatibilities if a bad version is selected.
From the tool's definition Tool name 'update' combined with description 'Updates dependencies in the lock file. Optionally updates a single package.' indicates modification of lock file contents.
Documented attack patterns abuse exactly the kind of access update gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Make, and nothing reaches the server without passing your rules. This is the rule we recommend for update:
{
"version": "1",
"default": "deny",
"tools": {
"update": {
"limits": [
{
"counter": "update_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}update 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.

Updates dependencies in the lock file. Optionally updates a single package. It is categorised as a Write tool in the Make MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Make MCP server in PolicyLayer and add a rule for update: 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 Make. Nothing to install.
update is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the update 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 update. 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.
update is provided by the Make MCP server (Dave-London/Pare). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Make, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
