From 49414a57aed0f82137186a28d79520cc268f926a Mon Sep 17 00:00:00 2001 From: RealDiligent Date: Wed, 22 Jul 2026 03:04:04 +0800 Subject: [PATCH 1/3] feat(mcp): add remote + stdio surfaces for loopover_get_ams_miner_cohort Mirror loopover_get_maintainer_noise on both the remote MCP server and local stdio wrapper. Cover authorized/forbidden remotely and instrument the bin via the #7764 in-process exported-server pattern so codecov/patch sees the new lines.
