E2B connector

Back to the connector overview, authentication methods, and actions.

data-syncAdded scheduled data sync to five collection actions — sandboxes, snapshots, templates, secrets and volumes — so these collections can be kept in sync and read back without calling E2B on every request. Sandboxes, snapshots, templates and secrets page through results automatically using E2B’s cursor; volumes are returned in full by a single request. All syncs use full refreshes, because no E2B list endpoint offers a last-updated filter.

releasePromoted to GA. Version normalized to 1.0.0 in line with the GA versioning policy (GA connectors are versioned 1.0.0 or higher); no functional changes in this version.

description-fixCorrected the pagination and reference documentation on the list actions — the next-page cursor comes back in the response body, not in an X-Next-Token header, and List Sandboxes no longer advertises a total running count that the response never carries, so counting means paging until the cursor is absent. Get Build Logs now states that a 502 from the temporary store is permanent rather than transient and those logs are read from the persistent store, Start Build’s command fields note that a local service is addressed without a URL scheme, and Compose Files points at documentation matching the endpoint it calls.
e2b_compose_files, e2b_get_build_logs, e2b_list_sandboxes, e2b_list_secrets, e2b_list_snapshots, e2b_list_template_builds, e2b_list_templates, e2b_start_build

bug-fix description-fixGet Sandbox Health and Start Build now return an explicit confirmation message instead of an empty string, so a successful call is no longer indistinguishable from no data. Descriptions were corrected across templates and sandboxes — E2B’s public built-in aliases such as “base” are accepted by Create Sandbox and its filters even though List Templates never returns them, Check Template Alias and List Template Builds only accept team-owned aliases and opaque IDs respectively, build logs read from the temporary store only while the builder is alive, and Fork Sandbox and Create Snapshot both require a running sandbox.
e2b_check_template_alias, e2b_create_sandbox, e2b_create_snapshot, e2b_fork_sandbox, e2b_get_build_logs, e2b_get_sandbox_health, e2b_list_sandboxes, e2b_list_template_builds, e2b_list_templates, e2b_start_build
