Use the MCP server when your client accepts MCP. Use the HTTP endpoint when your client does not accept MCP. - MCP server: https://app.mndatoday.com/mcp - Transport: Streamable HTTP - Authentication: none. The server needs no account and no key. - Setup: Add a custom connector or remote MCP server with this URL. Tools: - prepare_mnda: Prepares a mutual NDA draft. The fields and the default values are the same as the fields and the default values of the HTTP endpoint. The tool returns the link, the expiry time, and the next step. - check_prepared_mnda: Reads a prepared draft. The input is the link. The tool returns the title, the owner email address, the recipient name, the expiry time, and the claim status of the owner. - describe_mndatoday: Returns the product facts about MNDAtoday. The assistant never signs, never sends, never locks the document, and never pays. The account owner does these steps. ## Prepare a draft for a user An AI agent can prepare a mutual NDA draft for an account owner.
