Perplexity

Automate contract creation in Claude Desktop

Stop manually drafting agreements. Use `create_sign_flow` to initialize new contracts directly from your prompt, then pipe your documents in using `add_docs` without switching windows. Your agent handles the heavy lifting of template management. By calling `list_templates`, the server identifies the right structure for your needs before you finalize the paperwork.

Manage signers and execution via MCP Server

Adding participants to a flow is a one-step process. Invoke `add_signers` to attach specific individuals to a document, ensuring the right eyes see the contract immediately. Once everyone is set, trigger the process with `start_flow`. You get the signing link back instantly through `get_execute_url` to share with stakeholders.

Track signature status within Claude Desktop

Keep tabs on your deals by querying current progress. Use `get_sign_flow` to pull real-time updates on who signed and who hasn't, keeping your projects moving forward. If you need a record of completion, `list_sign_flows` gives you a bird's-eye view of all active contracts. It's the fastest way to stay updated without pinging your legal team.
