What before does on GitHub
AI agents call before 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 before is rated Low
This is a read-only pagination control mechanism. It retrieves data by positioning within result sets. No side effects, modifications, executions, or destructive operations are possible with a pagination cursor alone. The optional nature and explicit reference to pagination context further confirm it is a utility for data retrieval only.
From the tool's definition Tool description indicates 'Backward pagination cursor from previous pageInfo.prevCursor' — this is a pagination parameter used to retrieve data from previous pages, with no capability to modify, execute, or delete anything.
Attacks that exploit this kind of access
The rule that runs before 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 before, this is the rule to start with:
before 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 before call is checked against it from then on.
Questions about before
Backward pagination cursor from previous pageInfo.prevCursor (rare). (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 before: 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.
before 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 before 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 before. 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.
before 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.
