"LoopBack" matching MCP servers:

Local AI ops broker that keeps SSH secrets on your machine, exposes intent-level MCP tools to agents, and requires approval via a loopback Web UI for dangerous writes.

Enables MCP clients to observe and, when explicitly enabled, send constrained input to whitelisted tmux sessions, with support for local STDIO and loopback-only HTTP transport behind an authenticated tunnel.

A local MCP runtime that lets MCP clients such as ChatGPT inspect workspaces, search, read, write, and patch files, manage directories, run shell commands, and control persistent processes on your machine through an outbound Device Relay connection that needs no open inbound port. It can also publish a local loopback OpenAI-compatible model runtime as a Frely personal Provider.

Exposes local Mystilink calculator CLIs (bazi, ziwei, horoscope, lunar, tarot, liuyao) as MCP tools over stdio, with an optional loopback FastAPI for local debugging.

Enables ChatGPT web chat to access approved local files and run allowlisted commands through a secure loopback MCP bridge, with read-only enforcement and opt-in write capabilities.

A local Windows MCP server that lets a ChatGPT/OpenAI MCP client list, read, write, search, move, and delete files within allowed roots, run PowerShell/CLI commands, start and manage long-running processes, and inspect or commit/push Git repositories. It binds to loopback with policy-gated shell and Git mutations plus a local JSONL audit log.

Enables ChatGPT to safely interact with Windows workspaces through a loopback-only MCP server, with OAuth, bounded PowerShell tools, persistent jobs, and optional Cloudflare Tunnel exposure.

Enables MCP clients on macOS to perform bounded read-only filesystem operations and a narrow allowlist of process diagnostics over STDIO or authenticated loopback Streamable HTTP. It excludes file writes, arbitrary shell access, GUI/browser automation, and remote relay.
