What Goldcote does

MoltenRock

The encrypted vault for your API keys and AI agents. Keys and email credentials live behind your Mac’s Secure Enclave and are served, key by key, to the local agents you allow, with every use in an activity log. The outcome: your agents get access without secrets ever sitting in plain-text files.

MoltenMail

Secure email for you and your AI, read and draft only. Your agent reads, searches and drafts; every reply lands in your own Drafts folder for you to send. It can never send, delete or move a message.

MoltenRock Connect

Your business tools for your AI agent: Shopify, Stripe, WooCommerce and 28 more platforms. Agents read, with every request audited and customer names tokenised by default. On Stripe they can also propose changes, such as a refund, that wait for your approval in the Human Queue; the agent never holds a key that could make the change itself.

MoltenView

A canvas where your AI agents render visual content and interactive displays, locally on your Mac, without your data leaving it.

The Human Queue

Live in MoltenRock Connect for Stripe since September 2026: the changes an agent proposes, such as refunds and invoices, wait for your approval with Touch ID before anything is sent. Cloudflare is next. humanqueue.com shows how it works.

intents.md and its network

An open Markdown protocol for what someone wants, needs or offers, published at a URL any AI agent can read. Goldcote runs the reference directory at intentsmd.com and live answer engines and intent boards built on it, such as pickthehotel and picktheclick.

Development and AI integration

Custom AI-native apps, AI integration with human oversight, and security reviews for teams building with agents. Projects start by email, and Sylvain replies within 24 hours.

What makes Goldcote different

Local and hardware-backed, not another cloud vault

MoltenRock keeps secrets in your Mac’s Secure Enclave, with no account, no cloud and no telemetry. 1Password and HashiCorp Vault were built to store and sync secrets for people and servers; MoltenRock is built to serve them to the AI agents running on your own machine.

Agents get access, never the secrets

An agent gets scoped, per-key access that you can revoke in one click, and every use is logged. The raw key never lands in the agent’s context or in a plain .env file, which is where many agent setups keep it today.

Read freely, change only with a yes

MoltenMail can draft but never send. MoltenRock Connect reads across 31 platforms, and on Stripe an agent can only propose a change that a person approves. Automation tools such as Zapier are built to take actions for you; Goldcote’s apps are built so an agent can look freely and act only with a person’s approval.

An open protocol, no lock-in

intents.md is plain Markdown at a URL. Anyone can publish, any agent can read, and there is no platform in the middle taking a cut or owning the data.

Built lean, shipped fast

One founder, a bench of specialist contractors and AI agents have shipped 21 live products, including 4 MoltenRock apps and 3 Mac App Store releases, without outside funding.

Who Goldcote is for

Developers and AI-first professionals running local agents such as OpenClaw, Hermes, Claude Code, Cursor and Codex on a Mac.
Founders and small e-commerce and SaaS teams who want an agent to look up orders, payments and tickets without write access.
Anyone who wants an AI to triage and draft their email without handing over their password.
Travellers, collectors and buyers using the pickthe answer engines and intent boards, and the AI agents that read them.
Teams that need custom AI-native software built with security and human oversight.
