How a map on a café wall turned into an app that reads, maps and translates all 387 labels of an 1819 French map of the Bosphorus, built with Claude Opus 5.5 subagents in an afternoon.

Give Any Agent a Remote Workspace with One MCP Server

Add one MCP server to any agent, local or remote, and it gets a sandbox with a filesystem, your GitHub repos, a browser, file storage and the Upstash stack. Tell it what to build and come back to the pull requests

The Upstash MCP Server Is Now Remote

Our MCP server is now hosted at mcp.upstash.com/mcp. Connect any client over OAuth, with no local process and no API keys in your projects.

Every major way to run background jobs, message queues, and scheduled tasks from a serverless app in 2026: QStash, Inngest, Trigger.dev, Google Cloud Tasks, AWS SQS and SNS, Cloudflare Queues, and Vercel Cron, compared on HTTP delivery, retries, dead-letter queues, delays, cron, and price.

The Identity Index: Which LLMs Defend Answers They Never Gave?

We rewrite a model's own answer in the transcript to say the opposite, then ask it to explain itself. Across ten frontier models, 46% of replies defend the planted answer. Opus 4.8 almost never falls for it. Fable 5 does worse than both Opus and Sonnet.

How to Cut Claude Token Costs: Prompt Caching, Subagents, and Context Engineering

Practical ways to cut Claude token costs in Claude Code and on the API: prompt caching, model tiering with subagents, effort tuning, context engineering, skills, and Context7. The techniques work on every model, from Haiku 4.5 to Fable 5.

What 25 Years of Robot Automation Research Predicts About AI and Your Job

Factory robots (1990-2015) are the best natural experiment we have for machines replacing workers. The mechanics of displacement carry over to AI, but the target inverts: robots hit the least-educated hardest, while AI exposure rises with skill and income. A data-driven look at who actually loses their job.
