MCP Server: Variables & Template Tools

7 April 2026
Back to changelog

Variables

Five new tools let you manage reusable variables directly from your AI assistant. Variables are key-value pairs scoped to your team that can be referenced in workflow prompts using @variableKey syntax:

  • create_variable: Create a variable with a key, value, and data type (STRING, NUMBER, BOOLEAN, or JSON)
  • list_variables: List all variables in the current team scope
  • get_variable: Retrieve a variable by ID
  • update_variable: Update a variable's key, value, or data type — workflows referencing it will use the new value on their next run
  • delete_variable: Permanently delete a variable (with two-step confirmation)

Templates

Twelve new tools let you manage reusable templates that standardize workflow configurations across your team. Templates capture prompt, schema, data validation rules, and notification settings as versioned configurations:

  • create_template / get_template / list_templates / update_template / delete_template: Full CRUD for templates
  • create_template_version: Publish a version with prompt, schema, validation rules (regex, custom_sql, llm), and notifications
  • link_workflows_to_template / unlink_workflows_from_template: Associate workflows with a template (with two-step confirmation)
  • apply_template_update: Apply a specific version to linked workflows — roll out updates or roll back selectively
  • save_workflow_as_template: Create a template from an existing workflow's configuration
  • list_template_schemas / list_template_workflows: View schemas and linked workflows
