Finite E2B Connect-JSON filesystem and process inspection, mutation, watcher, input, signal, and stdin-control operations. Generated from the immutable official filesystem and process protobuf contracts at E2B commit 7474d904a2f6056f9528e73baf697368e03bf6ab; the official SDK's Connect JSON mode supplies the audited HTTP wire mapping. This leaf carries 13 of the suite's 72 admitted operations. Pick the sandbox-and-user-scoped E2B RPC connection carrying X-Access-Token, E2b-Sandbox-Id, and Authorization as Basic base64(username:). Use Basic dXNlcjo= for the default user. JSON request documents are sent verbatim, scalar integer selectors use exact decimal strings, unsafe JSON response integers remain exact strings, reads are uncached, private reads are marked sensitive-read, every mutation requires approval, and no sandbox or infrastructure object is misrepresented as a task, note, or project Source.
