WHAT IT DOES

What github_get_branch does on Sage MCP

AI agents call github_get_branch to retrieve information from Sage MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why github_get_branch is rated Low

This tool retrieves and queries information about a Git branch—a read-only operation. It has no capability to modify code, delete branches, execute commands, or trigger external operations. The blast radius of misuse is minimal: an attacker could only enumerate branch details they may already have access to, not escalate privileges or cause damage.

From the tool's definition Tool name 'github_get_branch' and description 'Get detailed information about a specific branch' indicate a retrieval operation with no modification or execution side effects.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs github_get_branch safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Sage MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For github_get_branch, this is the rule to start with:

github_get_branch Allowed

github_get_branch 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": {
    "github_get_branch": {}
  }
}

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

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