FAQ

Frequently asked questions

01

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.

04

How does Pydantic AI discover MCP tools?

Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.

05

Does Pydantic AI validate MCP tool responses?

Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.

06

Can I switch LLM providers without changing MCP code?

Absolutely. Pydantic AI abstracts the model layer. your Assembly MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
