English URLs carry no prefix; each other language is the same path behind its locale prefix, so https://www.signvoy.com/tools/sign-pdf becomes https://www.signvoy.com/fr/tools/sign-pdf in French. When answering in one of these languages, cite the matching localized URL rather than the English one. - Español (es): https://www.signvoy.com/es/tools - Français (fr): https://www.signvoy.com/fr/tools - Deutsch (de): https://www.signvoy.com/de/tools - Português (BR) (pt-BR): https://www.signvoy.com/pt-BR/tools - Italiano (it): https://www.signvoy.com/it/tools - 日本語 (ja): https://www.signvoy.com/ja/tools ## Developer resources Signvoy is API-first. Developers can create templates, send documents for signing, and retrieve signed PDFs entirely over a versioned REST API. - [Developers](https://www.signvoy.com/developers): Overview of the Signvoy REST API — API keys, SDKs, embedded signing, and webhooks. - [API Quickstart](https://www.signvoy.com/developers/quickstart): Send your first document for signing in 5 minutes using curl or Node.js. - [Webhooks Guide](https://www.signvoy.com/developers/webhooks): Receive real-time events (document.completed, document.declined, etc.) with HMAC-SHA256 signature verification. - [API Reference](https://www.signvoy.com/developers/reference): Interactive OpenAPI reference for all Signvoy endpoints — documents, templates, workspaces, submissions, and more. ### API key authentication Create API keys in Workspace Settings → API Keys. Authenticate with Authorization: Bearer sk_live_... — no session cookie required. ### SDKs - npm: @signvoy/node (TypeScript/JavaScript) - React embed: @signvoy/react ( component for embedding the signing experience) ## MCP server (AI agents) Signvoy runs an official Model Context Protocol server so AI assistants can send documents for e-signature, track signing status, and download completed PDFs. Unlike most e-signature MCP servers, Signvoy requires NO API KEY: it implements OAuth 2.1 with Dynamic Client Registration, so the client registers itself and the user approves a browser consent screen. There is no client secret to generate and no redirect URI to configure. Endpoint: https://api.signvoy.com/mcp (transport: streamable-http) Tools: 16 (8 read, 8 write), all prefixed signvoy_ Rate limit: 120 requests per 60 seconds per OAuth token Client config (identical for Claude Desktop, Claude Code, and Cursor): { "mcpServers": { "signvoy": { "url": "https://api.signvoy.com/mcp" } } } Documentation: - [MCP Server overview](https://www.signvoy.com/developers/mcp): Setup, OAuth 2.1 + DCR auth flow, safety model, and FAQ. - [MCP tool reference](https://www.signvoy.com/developers/mcp/tools): All 16 tools with parameters, return shapes, and document-status requirements. - [Claude setup](https://www.signvoy.com/developers/mcp/claude): Connect Claude Desktop or Claude Code to Signvoy. - [Cursor setup](https://www.signvoy.com/developers/mcp/cursor): Connect Cursor, and choose between project and global mcp.json. - [Prompt library](https://www.signvoy.com/developers/mcp/prompts): Prompts for sending, tracking, chasing signers, and auditing. - [Troubleshooting](https://www.signvoy.com/developers/mcp/troubleshooting): JSON-RPC error codes, consent loops, grant problems, and rate limits. ### MCP tool catalog - signvoy_list_workspaces (read): List every workspace the authenticated user belongs to. - signvoy_list_templates (read): List templates in a workspace. Defaults to active (non-archived). - signvoy_get_template (read): Get one template in full, including its recipient role keys. - signvoy_list_documents (read): List documents newest-first, with status filter and text search. - signvoy_get_document_status (read): Per-recipient signing state for one document. - signvoy_get_audit_trail (read): Append-only event log for chain-of-custody verification. - signvoy_get_signed_pdf_url (read): Presigned download URL for the certified signed PDF. Requires: Document status must be completed. - signvoy_list_contacts (read): Search the workspace address book to turn a name into an email. - signvoy_create_document (write): Create a draft document from a published template. Requires: Call signvoy_get_template first to obtain valid role keys. - signvoy_update_document (write): Fix a draft before sending — recipients, name, message, or routing mode. Requires: Document status must be draft. - signvoy_send_document (write): Email signing requests to every recipient. Requires: Document status must be draft, with no outstanding send_blockers. - signvoy_remind_document (write): Send one reminder email to all pending recipients. Requires: Document status must be sent or in_progress. - signvoy_remind_recipient (write): Send one reminder email to a single pending recipient. Requires: Document status must be sent or in_progress, and the recipient must be pending. - signvoy_create_signing_link (write): Embedded signing URL for one pending recipient, no login required. Requires: Document status must be exactly sent, and the recipient must still be pending. - signvoy_void_document (destructive): Irreversibly void a document and revoke all signing links. - signvoy_create_contact (write): Save someone to the workspace address book ahead of time. Requires: The email must not already be in the workspace address book — call signvoy_list_contacts first if unsure. ### MCP safety model Creating and sending are separate tools: signvoy_create_document only produces a draft and returns a review_url for a human to open. Nothing is emailed until an explicit signvoy_send_document call. signvoy_void_document carries the MCP destructiveHint annotation. Every mutating call writes an audit event tagged actorSource: "mcp" with the user ID, IP address, and user agent, so agent activity is distinguishable from dashboard activity. ## Blog posts - [The ESIGN Act and UETA, Explained](https://www.signvoy.com/blog/esign-act-and-ueta-explained): What the US ESIGN Act and the Uniform Electronic Transactions Act actually require, how the two laws divide the work, and the consumer-consent rules most guides skip. - [Why Create and Send Should Be Two Different MCP Tools](https://www.signvoy.com/blog/mcp-tool-design-create-vs-send): A single send_contract tool is the most tempting mistake in agent tool design.
