Show HN: Forth MCP – give any remote AI client access to your local MCP servers

Forth MCP, a hosted relay service, enables any remote AI client to access local MCP servers without port forwarding or VPN, using a lightweight connector installed as a background service. The service offers multi-endpoint connectors, per-token tool permissions, usage dashboards, and flat monthly pricing with hard usage caps.

Give any AI client access to your local MCP servers Forth MCP is a hosted relay that puts your local, NAT'd, or firewalled MCP servers behind a single secure URL. No port forwarding. No VPN. No exposing your machine. Install one lightweight connector, and any MCP-speaking AI client can call your tools from anywhere. MCP server / any MCP client Running in three steps No infrastructure to manage. The connector runs quietly in the background as a service. Install the connector One binary, installed as a background service on Windows, macOS, or Linux, straight from your dashboard. Attach your connector token One token authenticates every local MCP endpoint you add, npx package or plain HTTP address. Call it from anywhere Point any MCP client at your Forth MCP URL and API token. It just works, wherever your machine is. Everything you need to run MCP in production Built for real fleets of tools, not just a single local demo. One-command install A single self-contained binary. Runs as a Windows service, launchd agent, or systemd unit, published straight from your dashboard. Multi-endpoint connectors One connector token authenticates every local MCP endpoint you add, npx package or HTTP address alike. Add or remove them independently. Per-token tool permissions Scope each API token to an allowlist of tools, so different AI clients or teammates only ever see what they need. Usage dashboards & quotas See calls by token and by tool in real time, with configurable per-plan limits, threshold alerts, and an instant kill switch. Live health monitoring Know the moment a connector instance or endpoint drops. Re-add a deleted endpoint later without losing the rest of your connector. Built for agentic workflows A grace buffer protects an in-progress agent session. No hard cuts mid-task the instant a quota is hit. Simple, predictable pricing Flat monthly tiers with a hard usage cap. No metered billing surprises.
