15 tools

• estuary_list_catalog

  List live catalog entities (captures, collections, materializations, tests) the user can read, with connector + last-publication metadata. Optionally filter by a catalog-name prefix and spec_type. Estuary control-plane view live_specs_ext. PostgREST: GET /live_specs_ext.

• estuary_get_catalog_spec

  Get one live catalog entity by its exact catalog_name, including the full serialized `spec` and compiled `built_spec`. Estuary control-plane view live_specs_ext. PostgREST: GET /live_specs_ext?catalog_name=eq.<name>&limit=1.

• estuary_get_catalog_stats

  Get usage/throughput stats for one catalog entity — bytes & docs read/written (both directions), usage_seconds, warnings/errors/failures, and txn_count — per time grain. Optionally bound by a timestamp range. Estuary control-plane view catalog_stats. PostgREST: GET /catalog_stats

• estuary_list_connectors

  List the connector catalog — available capture/materialization Docker connectors, with titles, descriptions, and logos. Optionally filter to recommended connectors. Estuary control-plane table connectors. PostgREST: GET /connectors.

• estuary_list_connector_versions

  List available versions (image tags) of connectors, with protocol and documentation URL. Optionally filter by connector_id. Estuary control-plane table connector_tags. PostgREST: GET /connector_tags.

• estuary_list_drafts

  List the user's draft workspaces (staging areas for catalog edits before publishing). Estuary control-plane table drafts. PostgREST: GET /drafts.

• estuary_list_draft_specs

  List the staged spec entries within a draft (each an insert/replace of a catalog entity pending publication). Estuary control-plane table draft_specs. PostgREST: GET /draft_specs.

• estuary_list_publications

  List publication history/status — each publish attempt of a draft; job_status carries the queued/success/failed outcome. Estuary control-plane table publications. PostgREST: GET /publications.

• estuary_list_discovers

  List connector discovery jobs (auto-detecting bindings/resources for a capture). Estuary control-plane table discovers. PostgREST: GET /discovers.

• estuary_list_roles

  List the roles/capabilities the current credential is granted — which catalog prefixes it can read/write/admin. Read-only RPC. Estuary control-plane: POST /rpc/auth_roles.

• estuary_get_tenant

  Get the user's tenant(s) — quotas (tasks/collections), billing tiers, recurring charge, trial start, and payment provider. Estuary control-plane table tenants. PostgREST: GET /tenants.

• estuary_view_task_logs

  Fetch the log lines for a job by its logs_token (a UUID found on a publication, discover, or connector-tag record). Optionally page from a last-seen timestamp. Read-only RPC. Estuary control-plane: POST /rpc/view_logs.

• estuary_create_draft

  WRITE: create a new empty draft workspace (a staging area for catalog changes; does not affect live pipelines). Estuary control-plane: POST /drafts. Returns the created row.

• estuary_upsert_draft_spec

  WRITE: stage (insert or replace) a catalog spec inside a draft. Edits only the draft — live pipelines are unaffected until the draft is published. Estuary control-plane: POST /draft_specs (upsert on draft_id,catalog_name). Returns the staged row.

• estuary_publish_draft

  WRITE (DESTRUCTIVE when dry_run=false): publish a draft. dry_run=true (default) only VALIDATES the draft without changing anything. dry_run=false APPLIES the draft to the LIVE catalog — this can create, modify, or DELETE running data pipelines and their data. Set dry_run=false on
