How do I get a Dropbox Sign API Key?

Log in to your Dropbox Sign (HelloSign) account, navigate to **Settings > API**, and you can generate or retrieve your unique API Key from there. Note that API access may require a specific plan.

Can the agent send new signature requests?

This integration currently focuses on listing and auditing signature requests and templates. Sending new requests with document uploads should be managed via the Dropbox Sign web portal or mobile app.

Does the integration show specific signer statuses?

Yes, you can use the get_signature_request_details tool to see exactly who has signed, who is pending, and any specific events like views or declines.

Dropbox Sign + Pydantic AI FAQ

Common questions about integrating Dropbox Sign 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 Dropbox Sign MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
