"LoopBack" matching MCP servers:

Enables authenticated web agents to reach a local machine through a portable MCP endpoint, with optional Cloudflare Tunnel or Tailscale Funnel ingress for public access.

Enables MCP clients to search, read, and record reviewed conclusions from policy-gated allowlisted files, with sanitized chunks and create-only drafts or append-only lessons, without granting general filesystem or execution access. It supports lexical ranking and optional loopback embeddings while rejecting likely credentials and raw challenge flags.

Enables AI agents to inspect, read, create, format, edit, validate and convert DOCX, XLSX, PPTX and PDF documents through standard OOXML manipulation plus a locally installed R7 converter, without emulating mouse or keyboard input. It also optionally bridges to a document the user has open in R7-Office Desktop over loopback WebSocket.

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.

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 self-hosted MCP gateway that provides filesystem and shell capabilities for an isolated VPS workspace, with strict loopback security and optional authenticated remote access.

Exposes a governed suite of 38 OAuth-gated tools that let web-based AI chat clients read, write, edit, and search local files, run whitelisted shell commands, inspect databases and localhost APIs, drive browsers and DevTools, and manage background tasks, Git, clipboard, notifications, and ports. Local IDEs connect directly over loopback, while remote clients reach the same machine through a secure tunnel.

Exposes the local voidtools Everything index over MCP stdio on Windows, letting AI agents search, filter, aggregate, detect duplicates and grep file contents across millions of index entries in milliseconds instead of recursively scanning disks. It provides 13 tools and 3 resources, running loopback-only and read-only by default.

Provides fully local, privacy-preserving semantic search over file names and paths via MCP, using BGE embeddings for fuzzy matching and supporting incremental updates, watch mode, and a loopback-only HTTP server.

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.

A persistent AI partner MCP server that keeps identity, memory, goals and refusals in a local SQLite substrate, renting language work from Claude, ChatGPT, Kimi, local models or any BYOK OpenAI-compatible provider, with governed shell/fs/http tools, MCP "hands" gated by state-transition-validated cognition, loopback-only security, and tamper-evident audit.

Enables web-based AI agents such as claude.ai, ChatGPT and Grok to read and edit files and run allowlisted shell commands on your own machine, plus control Chromium, DevTools, ports, git, SQLite and background tasks. Access is exposed over HTTPS with OAuth 2.1 through a swappable public edge (Tailscale Funnel or a Cloudflare tunnel), with a loopback-only control panel for configuration.

Enables a remote MCP client to access narrowly scoped local filesystem resources and process capabilities through a loopback-only bridge. Supports guarded file reads, searches, and mutations, authenticated transport, and private reachability via OpenAI Secure MCP Tunnel.

Exposes an OAuth-gated MCP endpoint that lets web-based AI clients work directly on a local machine through 38 governed tools covering files, shell commands, search, Git, SQLite, browser automation, DevTools, background tasks, localhost services, clipboard, notifications, ports, and Postman control. Local tools can connect straight to the loopback address for offline, low-latency use, while remote clients reach the same machine over an optional public ingress.

Enables an AI client to manage candidate profiles and job postings stored in a local PostgreSQL database, match them deterministically, and generate tailored resume and cover-letter PDFs in English, French, German, and generic formats. It runs over stdio or a loopback HTTP endpoint with a bearer token, exposing 34 tools by default plus opt-in tools for imports, link fetching, deletions, and document export.

Enables a local Windows developer agent to perform atomic filesystem operations, validated AST-based code edits, PowerShell/CMD process execution, and durable SQLite-backed background jobs with system diagnostics. It can run either as a loopback Streamable HTTP server or over an outbound encrypted OpenAI Secure MCP Tunnel with a local supervisor control panel.

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.

Exposes an authenticated local runtime over OpenAI Tunnel so ChatGPT can inspect authorized Windows workspaces, read bounded Git status and diffs, submit and cancel Codex CLI tasks, and use workspace Skills. It also brokers connections to optional loopback stdio or HTTP MCP services, such as Stata and Zotero, with explicit tool allowlists and loopback-only access.
