Frequently asked questions
Can I automate the sending of a specific document template?
Yes! You can use the agent to map the document template and instantly send the signing request.
How can I track the signing status of a document?
Simply query the Task ID through the agent to retrieve its real-time signature status, whether pending or completed.
Do I need a paid plan to use the DottedSign API?
Access to the API generally requires an active DottedSign API subscription plan. Check the official docs for current restrictions.
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 DottedSign 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.
