Basematter
A library of open-source projects for agent-native developer tools.
The next decade of software will be written, run, and debugged in collaboration with agents. Most tooling still assumes a human at the keyboard. Basematter is a library of projects—the primitives meant for that shift.
Everything in the library is open source.
Copper
availableSee what your AI agent is actually doing.
A tiny CLI that tails MCP tool calls, redacts secrets, and flags risky ones.
Coral
availableAn open-source authenticated browser session manager for agents.
Local-first session bridge: agents borrow your already-authenticated browser sessions on a per-site, per-action, fully audited basis—Python daemon, Chrome extension, and MCP.
