Connections & Relations

Link processes and cards across workflows. 8 MCP tools.

Key concepts

• Pipe relations define parent/child structure between pipes (who connects to whom, constraints, auto-fill). Use get_pipe_relations on a pipe to list relation IDs and metadata.
• Card relations connect individual cards through an existing pipe relation: pass source_id = the pipe relation's ID (from get_pipe_relations). Default sourceType is PipeRelation; use extra_input (e.g., sourceType: Field) when the API requires a field-based link — see introspect_type on CreateCardRelationInput.
• Table relations in GraphQL are loaded by table-relation ID, not by database table ID: get_table_relations takes a non-empty list of those IDs.
• Connector fields are card fields (connection type), not pipe relations for writes. Prefer update_card + field_updates with operation ADD/REMOVE (related card ids). update_card_field is replace-all of the full id list; get_card value is display titles only — do not rebuild from it. This skill's get_card_relations still reads connector-field links (with card ids). create_card_relation / delete_card_relation write links through a pipe relation and are incremental — pick the surface that matches the link type.
