Forth MCP
Forth MCP is a hosted relay that lets remote AI clients like Claude or ChatGPT securely reach MCP servers running on your local machine, without port forwarding or a VPN.

Description
If you've built a useful tool that only runs on your own laptop — a local database, a home automation setup, an internal script — getting a cloud-based AI assistant to actually use it is normally a networking headache: you'd need to open ports on your router or set up a VPN, both risky and fiddly. Forth MCP is a small background app plus a hosted relay service that solves this the way a doorman solves building security: your laptop keeps its doors locked, and the AI client talks to the doorman instead, who forwards only approved requests to your machine.
In practice, you install a lightweight connector on the machine running your MCP (Model Context Protocol) server, attach an authentication token, and point your AI client (Claude, ChatGPT, or any MCP-compatible client) at a Forth MCP URL instead of your local address. The service supports multiple connectors and endpoints, lets you filter exactly which tools a given token can call, and gives you a real-time dashboard against your monthly call quota. There's also live health monitoring, audit logs (retention depends on plan), and a kill switch to instantly cut access if a token is compromised. It's a narrow, infrastructure-layer product — it doesn't run or host your MCP server itself, only the secure tunnel and permissioning between it and the outside world.
💬 Our review
The short version: Forth MCP solves a real, annoying problem — getting cloud AI clients to talk to tools on your own machine — with clear published pricing, though it's a fairly thin layer that technical users could partly replicate themselves.
The closest comparisons aren't other MCP products but general tunneling/remote-access services like ngrok or Cloudflare Tunnel, which expose a local port but aren't MCP-aware and don't offer per-token tool-level permission filtering or MCP-specific usage dashboards out of the box. Forth MCP's value is that MCP-specific polish: scoped tokens, a kill switch, and audit logs aimed at 'don't let a leaked token run arbitrary tools on my laptop.' At $12–$69/month for fairly modest call quotas (5,000 to 30,000 calls), it isn't cheap for what is fundamentally a relay, and users comfortable wiring up ngrok plus their own auth layer could do it cheaper — but for teams who want this solved without building it, the free tier (1 connector, 500 calls/month) is a reasonable way to try it first.

Pros
Purpose-built for MCP: per-token tool permission filtering, not just raw port exposure
No port forwarding or VPN setup required
Real-time usage dashboards and live health monitoring
Kill switch to instantly revoke a compromised token
Cons
Monthly call quotas are fairly low even on paid tiers (5k–30k calls)
Functionally a thin relay layer — technical users could replicate part of it with generic tunneling tools
