ap_list_flows

List flows in the current project with status, trigger type, and published state.

ap_flow_structure

Get the full structure of a flow: step tree, configuration status, step input values, router branch conditions, and valid insert locations. Shows the actual configured inputs for each step (URL, body, headers, etc.) so the AI can read and edit existing configurations.

ap_read_step_code

Read the full source code, package.json, and input mappings of a CODE step. Returns untruncated content — unlike ap_flow_structure which truncates code to 300 characters.

ap_read_step_settings

Read the full untruncated settings of any step, including the trigger: piece input, action/trigger name, loop items, router branches, and error handling options. Use this to see a step's current configuration before updating it — ap_flow_structure truncates piece input.

ap_validate_flow

Validate a flow for structural issues without publishing. Checks step validity, template references, and empty branches.

ap_research_pieces

Research available pieces. Use pieceNames for bulk exact lookup (always returns actions and triggers). Use searchQuery for fuzzy discovery.

ap_search_actions

Find piece actions by describing the task in natural language (e.g. "send a message to a Slack channel"). Returns the most relevant actions ranked by semantic similarity, or an empty list when nothing in the catalog matches — the tool does not force a match. Each result includes the piece name,...

ap_search_triggers

Find piece triggers (the event that starts a flow) by describing when the flow should run (e.g. "when a new row is added to a Google Sheet"). Same behavior and result shape as ap_search_actions, returning trigger names instead of action names.

ap_get_piece_props

Get the detailed input property schema for a specific piece action or trigger. Returns field names, types, required/optional, descriptions, default values, and dropdown options. When auth is required but not provided, automatically lists available connections. Use this before ap_update_step or...

ap_resolve_property_options

Resolve dropdown options for a single piece property. Returns available choices with labels and internal IDs. Use this to discover valid values for dynamic dropdown fields (e.g., Slack channels, Google Sheets, email labels) before configuring a step.

ap_resolve_property_chain

Resolve a chain of dependent dropdown properties in one call. For actions with cascading fields (e.g., Spreadsheet → Sheet → Columns), this resolves each property sequentially, feeding each selected value into the next resolution. Pass selectedValue for properties whose value you already know;...

ap_validate_step_config

Validate a step configuration before applying it. Returns field-level errors without modifying any flow.

ap_list_connections

List OAuth/app connections in the project. Required before adding steps that need authentication.

ap_list_ai_models

List configured AI providers and their available models. Use this to discover valid aiProviderModel values for configuring Run Agent steps.

ap_list_tables

List all tables in the project with their fields (name, type, id) and row counts.

ap_find_records

Query records from a table with optional filtering.

ap_list_runs

List recent flow runs with optional filters.

ap_get_run

Get detailed results of a flow run including step-by-step outputs, errors, and durations.

ap_setup_guide

Get step-by-step instructions for setting up connections or AI providers. Returns instructions for the user to follow in the UI — credentials are never handled through MCP.

ap_set_project_context

Set or clear the active project context. All tools require a project context to operate. Call with a projectId to select a project, or without to clear the selection. Always returns the list of available projects.

ap_create_flow

Create a new empty flow.

ap_duplicate_flow

Duplicate an existing flow. Creates a new copy with all steps, configuration, and canvas notes. Connections and sample data are not copied.

ap_rename_flow

Rename an existing flow.

ap_change_flow_status

Enable or disable a flow.

ap_delete_flow

Permanently delete a flow and all its versions. This cannot be undone.

ap_lock_and_publish

Publish the current draft of a flow. Validates all steps are configured.

ap_build_flow

Create a complete flow in one call — trigger plus any number of steps. Steps are added sequentially (trigger → step_1 → step_2 → ...). All steps are validated on creation. Use granular tools (ap_add_step, ap_update_step) to modify existing flows or add nested structures (loop contents, router...

ap_update_trigger

Set or update the trigger for a flow.

ap_add_step

Add a new step to a flow. Optionally configure it in the same call by providing input, auth, sourceCode, or loopItems.

ap_update_step

Update an existing step's settings. Auto-fills default values for optional properties.

ap_delete_step

Delete a step from a flow.

ap_add_branch

Add a conditional branch to a router step. The branch is inserted before the fallback (Otherwise) branch.

ap_update_branch

Update the conditions and/or name of an existing router branch without affecting the steps inside it.

ap_delete_branch

Delete a branch from a router step. Cannot delete the fallback (last) branch.

ap_manage_notes

Add, update, or delete canvas notes on a flow.

ap_create_table

Create a new table with an initial set of fields.

ap_delete_table

Permanently delete a table and all its data.

ap_manage_fields

Add, rename, or delete fields on a table.

ap_insert_records

Insert one or more records into a table.

ap_update_record

Update specific cells in a record. Only specified fields are changed.

ap_delete_records

Permanently delete one or more records.

ap_test_flow

Test a flow end-to-end in the test environment. Pass triggerTestData to provide mock trigger output when no sample data exists (e.g., for webhook triggers).

ap_test_step

Test a single step within a flow. Runs all steps up to and including the target step. Pass triggerTestData when no sample data exists.

ap_retry_run

Retry a failed flow run.

ap_run_action

Execute a single piece action once without building or saving a flow. Designed for one-shot tasks like "check my inbox" or "send one Slack message" where building a full automation would be overkill. Under the hood the action runs directly in the engine and the result is returned immediately —...
