Calls & messaging

Get a cable company's retention team to lower your internet bill

The agent said 'cancel' at Spectrum's phone menu to reach retention, waited about five minutes, then patched in the account holder when the rep would not deal with an assistant. The user came away with $55 a month for a year instead of $85.

Have Claude design a VGA logic board and fab it at JLCPCB for $6

Claude Opus 4.8 designed a 74-series logic and GAL circuit that outputs an EEPROM image over VGA. The owner routed it, JLC made it for $6, and it worked after one bodge wire.

Labs & biology

Run protein synthesis experiments in a cloud lab with GPT-5

OpenAI and Ginkgo Bioworks let GPT-5 design, run and interpret rounds of cell-free protein synthesis experiments on Ginkgo's automated cloud lab. It found a recipe that cut the cost per gram of protein by 40% against the prior best, with humans mainly loading reagents.

Mail & print

Have your agent mail a credit card dispute letter

A developer built AgentPostage so his agents can send real letters, and has used it for credit card and credit bureau disputes and a gym cancellation.

Move your smart home to Home Assistant with Claude

A Verge reviewer who had failed to switch to Home Assistant for years used Claude on a Mac Mini and moved about 70 percent of her devices over in one afternoon. Claude also deleted dashboard sections and picked wrong devices along the way.

Plan a Mars rover drive with Claude

NASA JPL engineers used Claude to plan waypoints for Perseverance from orbital images. On December 8 and 10, 2025 the rover drove about 400 meters on that route after human review and simulation.

One server, every upstream

Add the MCP URL once. Your agent finds tools with search_tools, reads a schema with get_tool and runs it with call_tool, whether the tool is ours or comes from another MCP server.

Free tools run now

22 live tools call free, openly licensed data (satellite radio observations, meteor detections). 59 more are federated from 8 public MCP servers: roads, subway, oceans, power markets, PCB parts. Every answer carries its source.

Paid ones, priced at the source
