brain_get_git_snapshot
AI agents call brain_get_git_snapshot to retrieve information from Mcp Brain without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'get_' prefix and naming convention strongly indicate this retrieves or queries git snapshot data without modifying it. While the empty description reduces confidence slightly, the context from sibling read-only tools on the same server supports a Read classification. No evidence of destructive, write, execute, or financial operations.

{
"version": "1",
"default": "deny",
"tools": {
"brain_get_git_snapshot": {}
}
}brain_get_git_snapshot is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
