What issue-update does on Build
AI agents use issue-update to create or update resources in Build, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Build environment.
Why issue-update is rated Medium
This tool creates or modifies data reversibly. It updates issue metadata fields without deleting them, making it a Write operation. Severity is medium because misuse could alter important project tracking information, but changes are reversible and don't involve financial transactions, code execution, or data deletion.
From the tool's definition Tool name 'issue-update' and description states it 'Updates issue metadata (title, body, labels, assignees, milestone, projects)' — modifies existing issue data through update operations.
Attacks that exploit this kind of access
The rule that runs issue-update safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Build, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For issue-update, this is the rule to start with:
issue-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.
The button opens the PolicyLayer dashboard: create your workspace, connect Build, apply this rule, and every issue-update call is checked against it from then on.
Questions about issue-update
Updates issue metadata (title, body, labels, assignees, milestone, projects). It is categorised as a Write tool in the Build MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Build MCP server in PolicyLayer and add a rule for issue-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 Build. Nothing to install.
issue-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 issue-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 issue-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.
issue-update is provided by the Build MCP server (Dave-London/Pare). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
