What show does on Http
AI agents call show to retrieve information from Http 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 statistics. It performs a query operation with no side effects—it does not create, modify, delete, or execute any code. The action is purely informational, making it a Read category tool with low severity since the blast radius of misuse is limited to information disclosure.
From the tool's definition The tool description states 'Shows commit details and diff statistics for a given ref', which are read-only operations that retrieve and display information without modifying data.
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 Http, 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 Http, 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 Http MCP Server, which means it retrieves data without modifying state.
Register the Http 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 Http. 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 Http MCP server (@paretools/http). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
