Tower-native Model Context Protocol (MCP) implementation

Playwright PHP library for browser automation: navigation, E2E tests, assertions, screenshots, and so much more!

A tiny, dependency-light Go daemon that hosts a remote Claude Code session over SSH: CLI-version manager + process supervisor + JSON-RPC multiplexer (with a replay buffer) over an AF_UNIX socket. Clean-room, cross-platform, no telemetry.

A composable framework for building reliable LLM agents on a harness you fully control. The same code runs the agentic loop on every model tier, local 4B to frontier with tool-call healing, verification, and durable crash-resume, on a typed 12-phase engine where every step emits an event you can hook into.
