Enables interaction with the SendForSign API to list document templates and read template content for electronic signature workflows.
  1. Create a SendForSign account

  2. Find (or retrieve) your API key

    • After signing in, open your dashboard and go to the "API Keys" tab — a new account will automatically generate an API key (and secret). Copy the API key; this is the value for SFS_API_KEY. (about.sendforsign.com)
  3. Create a Client (to obtain a client key)

    • Option A — Dashboard/UI: In the SendForSign dashboard look for a Clients / Client keys area and create a new client (fill fullname, email, organization). After creation copy the returned clientKey; this is the value for SFS_CLIENT_KEY. (about.sendforsign.com)
    • Option B — API: Use your API key to create a client via the /api/client endpoint. Example curl (replace placeholders):
      curl -X POST 'https://api.sendforsign.com/api/client'
      -H 'X-Sendforsign-Key: YOUR_API_KEY'
      -H 'Content-Type: application/json'
      -d '{"data":{"action":"create","client":{"fullname":"John Johnson","email":"[email protected]","organization":"Company Inc.","customKey":"YOUR_COMBINATION"}}}'
      The successful response will include "clientKey" — copy that for SFS_CLIENT_KEY. (about.sendforsign.com)
  4. (Optional) Generate short‑lived tokens / secrets if needed

    • If you need OAuth-style tokens or secrets for other flows, use the /api/token endpoint with your API key and Secret per the docs to obtain access tokens. (about.sendforsign.com)
  5. Fill the values into the FastMCP connection interface

    • Open the FastMCP connection / “Install Now” dialog where you add environment variables.
    • Add an environment variable named SFS_API_KEY and paste your SendForSign API key.
    • Add an environment variable named SFS_CLIENT_KEY and paste the clientKey you created.
    • Save/apply the settings and click the existing “Install Now” button to install/connect the SendForSign MCP server.
  6. Verify the integration

    • After installation, test the MCP tool (for example, call the list templates tool or hit the server health endpoint) to confirm authentication works. Example (MCP HTTP stream): send X-Sendforsign-Key and X-Client-Key headers when calling /mcp or use the MCP tool that lists templates. (about.sendforsign.com)
