## Tools (13)

- `census_get_destination`: Get a single destination connection by id. Census: GET /destinations/{id}.
- `census_get_model`: Get a single model by id, including its SQL/query. Census: GET /models/{id}.
- `census_get_source`: Get a single source connection by id. Census: GET /sources/{id}.
- `census_get_sync`: Get a single sync's full configuration by id. Census: GET /syncs/{id}.
- `census_get_sync_run`: Get a single sync run by id — status, counts, errors. Census: GET /sync_runs/{id}.
- `census_list_destinations`: List configured destination connections (SaaS apps data is synced INTO, e.g. Salesforce, HubSpot, Marketo). Census: GET /destinations.
- `census_list_models`: List SQL models / datasets defined in the workspace (the queries that produce rows to sync). Census: GET /models.
- `census_list_segments`: List audience segments defined in the workspace. Census: GET /segments.
- `census_list_sources`: List configured data warehouse sources (Snowflake, BigQuery, Redshift, Databricks, etc.). Census: GET /sources.
- `census_list_sync_runs`: List sync run history (each run's status, records processed, timing). Filter by sync_id. Census: GET /sync_runs.
- `census_list_syncs`: List syncs (a sync maps a source model to a destination object and keeps them in sync). Returns id, label, status, source_attributes, destination_attributes. Ce
- `census_list_workspaces`: List workspaces in the organization (note: usually requires an organization-level token). Census: GET /workspaces.
- `census_trigger_sync`: TRIGGERS a sync run for the given sync id — this KICKS OFF a live data sync that writes records into the connected destination SaaS tool. Set force_full_sync=tr
