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.

Tools

Tool (MCP)	CLI	Read-only	Purpose
get_pipe_relations	pipefy relation pipe list --pipe <id>	Yes	List pipe-to-pipe relations for a pipe.
create_pipe_relation	pipefy relation pipe create	No	Create a new pipe-to-pipe relation.
update_pipe_relation	pipefy relation pipe update <id>	No	Change relation config (auto-fill, constraints).
delete_pipe_relation	pipefy relation pipe delete <id>	No	Two-step destructive.
get_table_relations	—	Yes	Load table relations by relation ID.
get_card_relations	pipefy relation card list --card <id>	Yes	List all card-to-card relations on a card.
create_card_relation	pipefy relation card create	No	Link two cards through an existing pipe relation.
delete_card_relation	pipefy relation card delete <id>	No	Two-step destructive.

Steps — link two cards via an existing pipe relation

1. Get the pipe relation ID:

   MCP: get_pipe_relations pipe_id=67890

   CLI: pipefy relation pipe list --pipe 67890

   Note the id field on the relation (not the pipe ID).

2. Create the card relation:

   MCP: create_card_relation source_id=<PIPE_RELATION_ID> source_card_id=<PARENT_CARD_ID> target_card_id=<CHILD_CARD_ID>

   CLI: pipefy relation card create --source-relation <id> --source-card <id> --target-card <id>

3. Verify:

   MCP: get_card_relations card_id=<CHILD_CARD_ID>

Steps — create a new pipe relation

1. Create the relation between two pipes:

   MCP: create_pipe_relation parent_pipe_id=111 child_pipe_id=222 name="Support Escalation" auto_fill_field_id=<field_id>

   CLI: pipefy relation pipe create --parent 111 --child 222 --name "Support Escalation"

2. Use the relation — cards in the parent pipe can now be linked to cards in the child pipe using create_card_relation.

Success criteria

• get_pipe_relations returns the new relation with both pipe IDs.
• get_card_relations shows the linked card ID after create_card_relation.

Failure modes

• create_card_relation fails with "relation not found": source_id must be the pipe relation ID (from get_pipe_relations), not the pipe ID. These are different values.
• Table relations return empty: get_table_relations requires table-relation IDs, not table IDs. Get table-relation IDs from the table's connection config.
• delete_pipe_relation first call returns preview: expected — show preview to user, then call with confirm=true.
