MCP Server: Variables CRUD Tools

6 April 2026
Back to changelog

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)

Example: "Create a variable called api_url with value https://api.example.com"
