WHAT IT DOES

What get_tag does on GitHub

AI agents call get_tag 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.

Parameter	Type	Required	Description
`tag`	string	—	Tag name
`repo`	string	—	Repository name
`owner`	string	—	Repository owner

Parameters from the server's own tool schema.

RISK

Why get_tag is rated Low

This tool retrieves metadata about a git tag (a read-only operation). It does not create, modify, delete, or execute anything. The blast radius is minimal—an AI agent could only gain visibility into tag information, which is typically public or at least non-sensitive in most repositories.

From the tool's definition Tool name 'get_tag' and description 'Get details about a specific git tag in a GitHub repository' indicate a retrieval operation with no modification or side effects.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

get_tag Allowed

get_tag 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": {
    "get_tag": {}
  }
}

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 get_tag call is checked against it from then on.
