What show does on Build
AI agents call show to retrieve information from Build without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why show is rated Low
This tool retrieves and displays commit metadata and diff information without altering any state or executing commands. It is a passive query operation with no side effects, fitting the Read category.
From the tool's definition Tool 'show' performs read-only operations: 'Shows commit details and diff statistics for a given ref'. No modifications, deletions, or code execution are described.
Attacks that exploit this kind of access
The rule that runs show 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 show, this is the rule to start with:
show is read-only, so it stays allowed. 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 show call is checked against it from then on.
Questions about show
Shows commit details and diff statistics for a given ref. When. It is categorised as a Read tool in the Build MCP Server, which means it retrieves data without modifying state.
Register the Build MCP server in PolicyLayer and add a rule for show: 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.
show 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 show 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 show. 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.
show 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.
