Firma.dev + Claude
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 Claude
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.
Recommended path — works on claude.ai web without editing any config file.
- In Claude, open Customize → Connectors.
- Click +, then Add custom connector.
- Enter a name, e.g.
Firma.dev, and the remote MCP server URLhttps://cloud.anythingmcp.com/mcp/YOUR_SERVER_ID, then click Add. - Click Connect and sign in to AnythingMCP (OAuth) to allow access.
