Can I see who has already signed a document?

Yes. Use the `get_document` tool with the specific Document ID. The agent will return the list of participants and their respective signing status.

What is an audit log in Modusign?

An audit log records every action taken on a document, including when it was sent, opened, and signed, providing legal proof of the transaction. Use the `get_audit_logs` tool to retrieve this history.

How do I reuse my existing contract templates?

Use the `list_templates` tool to find the Template ID you need, and then provide that ID to the `create_document_from_template` tool along with the signer's details.

Modusign + Pydantic AI FAQ

Common questions about integrating Modusign MCP Server with Pydantic AI.

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.

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.

Can I switch LLM providers without changing MCP code?

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