Where do I find my API Key?

Your API Key can be found in your Assembly web portal under Settings > API.

02

What access does this MCP need?

It requires the REST API Key, giving access to clients, companies, users, and notes.

03

Can I browse workspaces and internal notes through the AI agent?

Yes. Use list_workspaces to see all workspaces and get_workspace to inspect a specific one. For notes, list_notes retrieves all entries and get_note fetches the full content of a specific note by ID.

How does Mastra AI connect to MCP servers?

Create an MCPClient with the server URL and pass it to your agent. Mastra discovers all tools and makes them available with full TypeScript types.

05

Can Mastra agents use tools from multiple servers?

Yes. Pass multiple MCP clients to the agent constructor. Mastra merges all tool schemas and the agent can call any tool from any server.

06

Does Mastra support workflow orchestration?

Yes. Mastra has a built-in workflow engine that lets you chain MCP tool calls with branching logic, error handling, and parallel execution.
