What labels does on GitHub
AI agents call labels to retrieve information from GitHub without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why labels is rated Low
This is a read-only filtering tool that retrieves or queries data based on label criteria. It has no side effects, does not modify data, and does not execute operations. The blast radius of misuse is minimal—returning filtered results cannot cause harm. Classified as Read/low severity.
From the tool's definition Tool name 'labels' with description 'Filter by labels' indicates a filtering/querying operation with no modification capability. The optional string array parameter suggests this is used to query or search GitHub items by their labels.
Attacks that exploit this kind of access
The rule that runs labels safely
PolicyLayer is an MCP gateway: it sits between your AI agents and GitHub, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For labels, this is the rule to start with:
labels 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 GitHub, apply this rule, and every labels call is checked against it from then on.
Questions about labels
Filter by labels (string[], optional). It is categorised as a Read tool in the GitHub MCP Server, which means it retrieves data without modifying state.
Register the GitHub MCP server in PolicyLayer and add a rule for labels: 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 GitHub. Nothing to install.
labels 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 labels 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 labels. 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.
labels is provided by the GitHub MCP server (oci:ghcr.io/aifity/omnigit-mcp:0.5.0). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
