The core ACT spec is small: a tool-dispatch interface and a few CBOR shapes on the wire, with stateful capabilities (sessions, events, resources) layered on as separate opt-in packages.

Exposes query , exec , batch-exec , schema . Uses rusqlite compiled to wasm32-wasip2 with the wasi-sdk toolchain; the database file is whatever path the operator grants via --fs-allow . npx @actcore/act run ghcr.io/actpkg/sqlite:latest --mcp \ --fs-policy allowlist --fs-allow /data/app.sqlite Enter fullscreen mode Exit fullscreen mode Also ships a sqlite-vec variant with sqlite-vec linked in for vector-index queries.…
