Firma.dev + ChatGPT
Firma.dev e-signature from any AI agent: templates, signing requests from a template, sending and reminders, recipient status, audit trail and signed PDFs. 13 tools, API-key auth, with free test keys.
Prerequisites
See the full setup instructions baked into the connector (visible in the in-app store when you select the connector). The required environment variables for this connector are:
FIRMA_API_KEY
Step 1 — Get credentials
This connector drives Firma.dev (api.firma.dev), a developer-first e-signature API: templates, signing requests (envelopes), their recipients, audit trail and signed documents. 13 tools.
Setup
- Sign up at https://firma.dev (free, no card) and open your workspace in the dashboard.
- Copy an API key into
FIRMA_API_KEY. Every workspace has two: the test key creates watermarked test requests and consumes no credits, the live key sends real, legally binding requests and consumes one credit per envelope (about €0.049). Start with the test key. - The key is sent as the
Authorizationheader, without a Bearer prefix. It is stored encrypted.
…(continued in the in-app connector instructions)
Step 2 — Install the adapter
curl -fsSL https://raw.githubusercontent.com/HelpCode-ai/anythingmcp/main/docker-compose.quickstart.yml -o docker-compose.yml
printf 'JWT_SECRET=%s\nENCRYPTION_KEY=%s\n' "$(openssl rand -hex 32)" "$(openssl rand -hex 32)" > .env
docker compose up -d
Step 3 — Add the connector in ChatGPT
Your server URL: in AnythingMCP, open MCP Servers → the server this connector is on, and copy its URL (
https://cloud.anythingmcp.com/mcp/…). Use it wherever this guide showsYOUR_SERVER_ID.
ChatGPT connects to MCP servers as custom apps in developer mode, available on paid plans (not on Free). On Business and Enterprise workspaces an admin may have to allow it first.
- In ChatGPT, open Settings → Security and login and turn on Developer mode.
- Go to chatgpt.com/plugins and click +.
- Enter a name and a short description, e.g. Name:
Firma.dev. - Under Connection, enter the MCP server URL
https://cloud.anythingmcp.com/mcp/YOUR_SERVER_IDand create the connection. - When ChatGPT asks, sign in to AnythingMCP (OAuth) and allow access.

FAQ
Does the free ChatGPT plan work with custom MCP connectors? No. Custom MCP connections need developer mode, which is only on paid plans.
