How Zapier MCP tools work

How Zapier MCP discovers and manages tools: dynamic tool discovery via meta-tools, auto-provisioning, and Skills.

Most Zapier MCP servers use dynamic tool discovery. Your agent discovers and enables tools during conversation, with no manual setup required.

Dynamic tool discovery

In the default mode, your AI agent manages its own toolset. When you connect via OAuth, Zapier auto-provisions tools from your existing connected apps. From there, your agent can:

• Search for available apps and actions using discover_zapier_actions.
• Enable a specific action using enable_zapier_action.
• Run read actions (searches, lookups) using execute_zapier_read_action.
• Run write actions (send, create, update) using execute_zapier_write_action.

Your agent adapts to requests in real time. It does not need a pre-configured list of tools before it can help.

Meta-tools

Your server exposes 15 static meta-tools across five categories. These are always available regardless of which apps you have connected.

Tool	Category	What it does
list_enabled_zapier_actions	Action management	Lists all currently enabled actions on your server
discover_zapier_actions	Action management	Searches for apps and actions available to add
enable_zapier_action	Action management	Enables a specific action as a callable tool
disable_zapier_action	Action management	Removes an action you no longer need
auto_provision_mcp	Action management	Automatically provisions tools from your existing Zapier connections
write_code_action	Action management	Creates a custom code action for an app when no built-in action matches the request
execute_zapier_read_action	Execution	Runs a read or search action (find an email, look up a contact)
execute_zapier_write_action	Execution	Runs a write action (send a message, create a task, update a record)
get_configuration_url	Configuration	Returns the URL to your Zapier MCP configuration page
list_zapier_skills	Skills	Lists saved Zapier Skills
get_zapier_skill	Skills	Retrieves a specific Skill by name
create_zapier_skill	Skills	Creates a new Skill
update_zapier_skill	Skills	Updates an existing Skill
delete_zapier_skill	Skills	Deletes a Skill
send_feedback	Feedback	Sends feedback to Zapier

Auto-provisioning

When you connect to Zapier MCP via OAuth, the auto_provision_mcp tool runs automatically. It sets up your server based on the apps you have already connected in your Zapier account.

Auto-provisioning covers your own Zapier connections only. Apps or connections shared with you by another Zapier user are not included.

After auto-provisioning completes, your agent can immediately start working with those apps. You can expand coverage at any time by asking your agent to search for and enable additional actions.

Skills

Skills are reusable, Markdown-based workflow instructions your agent can load on demand. Zapier includes packaged Skills, including an onboarding Skill and example Skills, to show how to build your own. With Skills, you can capture complex, multi-step workflows and turn them into reusable instructions.

You can manage Skills using the five Skills meta-tools, or directly in the Skills tab at mcp.zapier.com.

Manual configuration

Some servers use manual configuration instead of dynamic discovery. In this mode, each action is exposed as a dedicated tool and you configure tools at mcp.zapier.com rather than through the agent.

Manual configuration is useful when you need:

• A fixed, predictable toolset: your client always has the same tools available, with no dynamic discovery.
• Tightly scoped access: you control exactly which actions are available, with no ability for the agent to enable new ones.
• Pre-configured field values: lock specific field values for each tool, useful for repeatable or automated tasks.
