Run a write action in an app
Runs one write action in an app connected to Zapier, such as sending a message, creating a task or updating a record, and returns the result.
Note: Reaches real people and records: confirm the inputs first. Runs through the app's default connection unless you pass a connection_id. Each successful MCP call uses two tasks from the Zapier plan.
Set up
Use the first option your agent supports.
MCP (official, remote)
Add this server to your agent's MCP settings, then sign in when asked.
{ "mcpServers": { "zapier": { "url": "https://mcp.zapier.com/api/v1/connect" } } }
Call the MCP tool execute_zapier_write_action.
Server URL: https://mcp.zapier.com/api/v1/connect
CLI (official)
Install the command and sign in with it, then confirm it runs.
npm install -g @zapier/zapier-sdk-cli
zapier-sdk --version
Run zapier-sdk run-action.
Before anything else, confirm access with the cheapest read-only call, like a list or a search. Never send or change anything to test access.
Rules
- Ask the user before anything that sends messages, costs money, or changes data, and say how many records it touches. One approval covers a batch the user has seen.
- Never print API keys.
