Inkly is legally binding eSignature software for professionals and small businesses. This repository describes Inkly's hosted MCP server, which lets an AI assistant work with your Inkly account in plain language:
Find templates and see which roles and fields each one needs.
Prepare documents from a template or a PDF, ready for you to check and send.
Track signing: who has signed, who is still waiting, and whether an invitation bounced.
Get the signed PDF of any completed document.
Send documents and reminders, or void a document, when you give the assistant Full access.
Ask things like "Which of my agreements are still waiting to be signed?" or "Prepare the consulting agreement for Alex Morgan at alex@example.com."
There is nothing to install. The server is hosted by Inkly and you sign in with your Inkly account.
## Server URL
https://www.inkly.so/mcp
Transport: Streamable HTTP
Sign-in: OAuth 2.1 with dynamic client registration. Your assistant opens Inkly, you choose a workspace and an access level, and click Allow.
Use www.inkly.so, not inkly.so. Assistants lose their sign-in on the redirect.
You need an Inkly account. Create one here.
## Connect

### Cursor

json
"mcpServers": {
"inkly": {
"url": "https://www.inkly.so/mcp"
Cursor shows Inkly under MCP settings with a Connect button. Click it and approve the connection in Inkly.
### Claude Code
bash
claude mcp add --transport http inkly https://www.inkly.so/mcp
Then run /mcp in Claude Code, choose Inkly, and approve the connection in your browser.
### Codex
bash
codex mcp add inkly --url https://www.inkly.so/mcp
Codex opens your browser to approve the connection.
### n8n and your own agents
Agents that run without a person signing in use an API key instead, sent as Authorization: Bearer ink_live_… over Streamable HTTP. In n8n, add the MCP Client node with HTTP Streamable transport and Bearer Auth. API keys are available on Pro and Teams.
## Access levels
You pick a workspace and an access level each time you approve a connection, and can change it any time in Settings → Integrations. Each level includes the one before it.
| Level | What the assistant can do |
| Read | Find and read templates and documents. |
| Prepare (default) | Create drafts that you check and send in Inkly. Nothing is emailed until you press Send. |
| Full access | Send from your templates without review, send reminders, and void documents. Pro and Teams. |
