Lessons from shipping six connectors. https://tayyabcheema.com/blog/grok-bot-tasks-without-api.html https://tayyabcheema.com/blog/grok-bot-tasks-without-api.html Thu, 01 Oct 2026 09:00:00 +0000 xAI's Grok Bot has no API for sending messages. Here is a working pattern that lets Claude or any automation delegate tasks to Grok Bots through an inbox and outbox on their shared computer, with the exact standing instruction to paste. https://tayyabcheema.com/blog/claude-connector-google-oauth-redirect-uri-mismatch.html https://tayyabcheema.com/blog/claude-connector-google-oauth-redirect-uri-mismatch.html Thu, 01 Oct 2026 09:00:00 +0000 Building a remote MCP server for claude.ai with Google OAuth and FastMCP? The redirect_uri_mismatch error almost always means the wrong callback was registered, or on the wrong Google client. The two redirect URIs explained, with working code and checks. https://tayyabcheema.com/blog/three-ais-one-connector.html https://tayyabcheema.com/blog/three-ais-one-connector.html Thu, 01 Oct 2026 09:00:00 +0000 A real build where Claude designed and planned, the Grok CLI wrote the code test-first, and the Codex CLI reviewed every task. What the reviewer caught, the incident that changed my rules, and when this beats Claude Code vs Codex comparisons. https://tayyabcheema.com/blog/claude-code-sandbox-proxmox-vms.html https://tayyabcheema.com/blog/claude-code-sandbox-proxmox-vms.html Thu, 01 Oct 2026 09:00:00 +0000 A sandbox for AI coding agents that is a whole virtual machine: cloned from a golden image in seconds, on a walled network behind an allow-list proxy, created by Claude through an MCP connector and destroyed automatically when its time runs out. https://tayyabcheema.com/blog/ssh-mcp-server-reverse-tunnel.html https://tayyabcheema.com/blog/ssh-mcp-server-reverse-tunnel.html Thu, 01 Oct 2026 09:00:00 +0000 Giving Claude a shell on a remote machine through an SSH MCP server and a reverse tunnel. Three failure modes that cost me real time: a tunnel that loops back to itself, host keys that change on every restart, and an OpenSSH penalty that locks the connector out.
