Packages

Core: hanzoai (API client) · hanzo-mcp (MCP server — thin wrapper that discovers tools via [project.entry-points."hanzo.tools"]) · hanzo-memory · hanzo-repl · hanzo-agent.
Tools (each exports a TOOLS list via its entry point): hanzo-tools-{shell,browser,fs,memory,reasoning,agent,api,lsp,refactor,llm,…}.

hanzo-mcp  ──entry points──►  hanzo-tools-*   (each: a TOOLS list)

Browser tools (hanzo-tools-browser) — zapd consumer

hanzo-mcp hosts no server. It connects to the shared local router ~/.zap/run/zapd.sock (see ~/work/zap) as a consumer, lists providers, and routes opaque CDP to a browser:* provider (the real Chrome/Firefox extension via its native host). No in-process server, no mDNS, no port pool, no HTTP bridge, no Playwright fallback in native-browser mode.

from hanzo_tools.browser.zapd_consumer import get_consumer
c = get_consumer()                          # ~/.zap/run/zapd.sock
c.resolve_browser("chrome", None)           # -> browser:chrome/<host>/default
c.route(provider, "Target.getTargets", {})  # opaque command, raw result bytes

Two tools, one transport: browser (high-level verbs) + cdp (raw CDP method by name). Files: zapd_consumer.py (envelope codec + consumer), browser_tool.py, cdp_tool.py. Unit-tested in tests/test_browser_tools.py (zapd mocked) + against a live zapd; the router (zap-proto/zapd) owns the transport tests.

hanzo-mcp pins hanzo-tools-browser[playwright]>=0.5.8 (the zapd-consumer version); the Claude Code MCP entry sources it from disk via uvx --from pkg/hanzo-mcp --with-editable pkg/hanzo-tools-browser.

Memory

SQLite + optional vector (sqlite-vec). ~/.hanzo/{memory,db} global, .hanzo/ per project. Backends: local (default), sqlite, lancedb, kuzu.

API tool (hanzo-tools-api)

Generic REST over OpenAPI specs (~/work/hanzo/openapi/). Auto-detects GITHUB_TOKEN, OPENAI_API_KEY, etc. api(action="list|config|call|spec|ops", provider=…). Hanzo providers: hanzo, hanzo-iam, hanzo-gateway, hanzo-commerce, hanzo-vector, hanzo-cloud, hanzo-nexus.

Common issues

Import error → uv sync --all-packages. Missing tool → check the entry point in the package's pyproject.toml. Backend unavailable → install the optional dep.
