Use Emboss in Gemini

Emboss runs an MCP server at https://api.getemboss.ai/mcp. Connect it once and fill PDF forms from a conversation: make a flat PDF fillable, fill it from notes or documents you paste or attach, or fill it for every row of a spreadsheet. Sign in with an Emboss account when prompted. Emboss is not yet listed in Gemini's app directory, at the time of writing.

For a company's Gemini Enterprise, see Use Emboss in Gemini Enterprise.

Connect

  1. Open Connected Apps in Gemini settings.
  2. Add a custom app.
  3. Paste the server URL: https://api.getemboss.ai/mcp.
  4. Sign in to Emboss when prompted.

Availability

Available in Gemini Spark on Google AI Ultra and Pro, for personal Google accounts in the US, at the time of writing.

What you can do

  • Make a flat PDF fillable. Attach a PDF and ask Gemini to detect its fields; see the MCP tools reference for create_form.
  • Fill a form from context. Attach a form and one or more context documents; see fill_form_from_context for how the match works.
  • Fill a form for every row in a spreadsheet. Attach a form and a spreadsheet; see fill_batch for the mapping and row output.

For developers (Gemini API)

The Gemini Interactions API's mcp_server tool takes a server URL plus static headers instead of an OAuth flow. Use an Emboss API key (see Authentication) as the bearer token:

{
  "tools": [
    {
      "mcp_server": {
        "url": "https://api.getemboss.ai/mcp",
        "headers": {
          "Authorization": "Bearer sk_..."
        }
      }
    }
  ]
}

Billing and privacy

Free tier: The first 5 form creations, 5 context fills, 5 standard fills, 5 verifications, 5 reads, and 5 packages each month are free when the job is 5 pages or fewer (a context fill counts the form and its documents together); a longer job is charged and does not use a free one. See Pricing for current rates. Only the arguments a tool call needs are sent to Emboss. Disconnect at any time from Dashboard, then Account, then Connected apps. A connection made with an API key is not listed there: revoke or turn off the key on the API Keys page instead.
