Self-host an AI email agent on Cloudflare Workers: agentic-inbox set up and costed

Cloudflare's open-source agentic-inbox runs a full email client on Workers, with one SQLite Durable Object per mailbox and a Kimi K2.5 agent that drafts replies. Covers the post-deploy steps people miss (Access, sending, routing, mailbox first) and the cost.

Oct 1, 2026 · 8 min readNearly a million leaked links: auditing what your AI agents leave on the public webOpenAI's agent swarm left almost a million public shortener URLs holding credentials. Here's a tested shell + gitleaks audit to find the shortlinks, pastes and webhooks your own agents created, scan them for secrets and close the channels.#security#agents#secrets#gitleaks

Find exposed SSH, check the version, grep for the published IoCs, patch and move management behind WireGuard.#security#mikrotik#routeros#ssh

Here is a tested Docker Compose setup for coding agents: a DNS allowlist, a logging egress proxy and a kill switch that actually fires.#security#docker#agents#dns

What each AI bot directive controls, why robots.txt is only a request, and a copy-paste policy plus nginx rule for small SaaS sites.#ai#robots-txt#seo#cloudflare

All posts

// what I write about — and build

Three topics. Also three things I build for clients.

Every topic has posts to read and a free quote if you want it built for your data and systems.

RAG & semantic search

Search and assistants that answer from your own documents — with sources, and a handoff when they’re not sure.

Embeddings & vector search
Hybrid keyword + meaning search
Assistants with citations

AI integrations

LLMs wired into the systems you already run — tickets, CRM, catalog, inbox — with costs and quality you can see.

Summaries, drafts, classification
Translations and content generation
APIs, webhooks, your own model

Agent pipelines

Multi-step agents as inspectable workflows — they plan, act and check, and a person approves anything that matters.

Workflows you can open and trace
Human approval steps
Event-driven, retry-safe backends
