Frequently Asked Questions
How do I connect Postmark to my app?
Use Weavz Hosted Connect for Custom authentication. Install the SDK, create a connection through the connect portal or API, then execute tools programmatically.
What tools does Postmark support?
Postmark supports 6 tools including Send Email, Send Template Email, List Templates, List Message Streams, Search Outbound Messages, and more.
Can I use Postmark with AI agents?
Yes. Add Postmark to an MCP server in Tool Mode or Code Mode. Code Mode provides 3 meta-tools with on-demand API discovery so agents can compose stateful workflows without loading every action schema up front.
How do I connect Postmark to ChatGPT or Claude?
Open the Weavz connector setup, sign in, choose a workspace, and add Postmark as an approved app. ChatGPT, Claude, and other remote MCP clients can then call the scoped Postmark tools exposed by that workspace.
Does Postmark work with Claude Code, Cursor, Codex, and local agents?
Yes. Remote and local MCP clients can connect to a Weavz MCP endpoint for the workspace. Local coding agents can also use the Weavz CLI to inspect apps, discover actions, run approved Postmark work, and execute Code Mode workflows from a terminal.
What can I ask an AI agent to do with Postmark?
Postmark exposes 6 tools, including Send Email, Send Template Email, List Templates, List Message Streams, Search Outbound Messages, and more. Use Weavz to keep credentials scoped, require approval for sensitive work, and audit what the agent did.
Can Postmark be used in stateful agent workflows?
Yes. Agents can combine Postmark tools with Filesystem, State KV, Human Gates, input partials, and other workspace integrations while keeping execution scoped to the selected workspace or end user.
What authentication does Postmark use?
Postmark uses Custom. Weavz stores credentials securely and uses them for authorized action execution.
