Frequently asked questions
Can I use this server to actually send operational emails from my account?
Yes! The send_email and send_email_with_template tools will dispatch active live emails using your Postmark server configuration.
How can I debug a specific user reporting that they didn't receive an email?
You can ask the agent to execute search_outbound_messages or search_bounces using their exact email address. The agent will fetch the delivery log and status codes.
Do I need the Account Token or the Server Token to use this?
You only need the Server Token. Postmark divides workflows by servers (environments). Supplying the server token isolates this specific operational environment perfectly.
How does LlamaIndex connect to MCP servers?
Use the MCP client adapter to create a connection. LlamaIndex discovers all tools and wraps them as query engine tools compatible with any LlamaIndex agent.
Can I combine MCP tools with vector stores?
Yes. LlamaIndex agents can query Postmark Alternative tools and vector store indexes in the same turn, combining real-time and embedded data for grounded responses.
Does LlamaIndex support async MCP calls?
Yes. LlamaIndex's async agent framework supports concurrent MCP tool calls for high-throughput data processing pipelines.
