Use Emboss in ChatGPT

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 the ChatGPT plugin directory, at the time of writing.

Connect

Go to Settings, then Security and login, and turn on Developer mode.
Go to Plugins and add a server by URL: https://api.getemboss.ai/mcp.
Sign in to Emboss when prompted.

Availability

Available on paid ChatGPT plans (Free is excluded). In a Business or Enterprise workspace, an admin needs to publish it before members can use it. A ChatGPT plugin listing is in progress.

What you can do

Make a flat PDF fillable. Attach a PDF and ask ChatGPT 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.

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.
