WHAT IT DOES

What revision does on GitHub

AI agents call revision 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.

RISK

Why revision is rated Low

This tool appears to be a parameter for retrieving or showing data about a specific git revision. It has no side effects—it simply specifies which commit, branch, or tag to query. This is consistent with Read category tools that retrieve data without modification.

From the tool's definition The tool accepts a revision identifier (commit hash, branch name, or tag) as a parameter. This is a lookup/query parameter used to specify which git revision to display or retrieve information about.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs revision 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 revision, this is the rule to start with:

revision Allowed

revision is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "revision": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect GitHub, apply this rule, and every revision call is checked against it from then on.

FAQ

Questions about revision

What does the revision tool do? +

The revision (commit hash, branch name, tag) to show (string, required). It is categorised as a Read tool in the GitHub MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on revision? +

Register the GitHub MCP server in PolicyLayer and add a rule for revision: 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.

What risk level is revision? +

revision is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit revision? +

Yes. Add a rate_limit block to the revision 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.

How do I block revision completely? +

Set action: deny in the PolicyLayer policy for revision. 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.

What MCP server provides revision? +

revision 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.
