## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "gluecron_create_branch",
    "arguments": {
      "sha": "<sha>",

## Why gluecron_create_branch is rated Medium

Creating a branch ref is a write operation that modifies repository metadata by adding a new reference to an existing commit. It is reversible (branches can be deleted) and does not execute code, delete data irreversibly, or move funds. The blast radius is moderate—an AI agent could create numerous branches or pollute the namespace, but this can be undone.

From the tool's own definition: "Tool description states 'Create a new branch ref pointing at an existing sha' and 'Mirrors POST /api/v2/repos/.../git/refs', indicating a POST operation that creates new git references."

## Use case

AI agents use gluecron_create_branch to create or update resources in Gluecron, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Gluecron environment.

## Recommended policy (PolicyLayer)
