Get the branch-protection configuration for a branch (404 -> unprotected).
AI agents call get_branch_protection to retrieve information from Ghe Mcp Gateway without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves branch protection settings without creating, modifying, or deleting data. It is a safe read operation consistent with the server's stated 'read-only safety by default' design. The blast radius of misuse is minimal—an attacker can only view security configuration, not alter it.
From the tool's definition Tool name 'get_branch_protection' and description 'Get the branch-protection configuration for a branch' indicate a retrieval operation with no modification capability. The 404 response behavior confirms read-only semantics.
Attacks that exploit this kind of access
Get the branch-protection configuration for a branch (404 -> unprotected). It is categorised as a Read tool in the Ghe Mcp Gateway MCP Server, which means it retrieves data without modifying state.
Register the Ghe Mcp Gateway MCP server in PolicyLayer and add a rule for get_branch_protection: 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 Ghe Mcp Gateway. Nothing to install.
get_branch_protection 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 get_branch_protection 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 get_branch_protection. 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.
get_branch_protection is provided by the Ghe Mcp Gateway MCP server (mholzinger/ghe-mcp-gateway). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
