AI assistants are increasingly becoming the interface for business software. Now, one e-signature platform wants to make sending legally binding documents as easy as asking an AI to do it.

Firma.dev has launched Firma 12, a major update to its developer-focused e-signature API that introduces dual Model Context Protocol (MCP) servers. The integration allows users to send, track, and manage document signatures directly through AI tools such as ChatGPT, Claude AI, Cursor, GitHub Copilot, Visual Studio Code, and OpenAI Codex.

The update positions Firma.dev among a growing group of platforms building AI-native integrations that allow conversational interfaces to perform real operational tasks—rather than simply generating content or summaries.

AI as the New Interface for E-Signatures

Firma 12 introduces two MCP servers designed to connect AI tools directly with the platform.

The Docs MCP server, released earlier in 2026, enables developers to query live API documentation inside coding environments. The newly released Data MCP server goes further by allowing AI tools to perform real actions inside a Firma.dev account.

The system exposes 84 AI-ready tools across 10 operational categories, enabling users to create signing requests, manage templates, track envelope statuses, configure webhooks, and query usage data.

According to Derick Dorner, co-founder of Firma.dev, the goal is to remove traditional barriers between users and digital document workflows.

“You can literally say ‘send the standard NDA to Sarah’ inside Claude, and it happens,” Dorner said. “You don’t need to be a developer. You don’t need to learn an API. You just talk to your AI.”

Authentication is handled through OAuth, meaning users can connect their AI tools simply by adding the MCP server URL and signing into their Firma.dev account.

Competing on Price in the E-Signature Market

Alongside its AI integrations, Firma.dev is also competing aggressively on cost.

The company charges €0.029 per envelope, roughly three U.S. cents, using a pure pay-as-you-go model without contracts, per-seat fees, or monthly minimums.

That pricing stands in contrast to legacy e-signature platforms such as DocuSign, where enterprise customers can pay anywhere from $1 to more than $5 per envelope depending on plan structure and volume.

The pricing difference has already attracted customers processing large document volumes.

Paul Jolley, CEO of Hawaiian property management platform Clear, said switching platforms could reduce his company’s annual costs by thousands of dollars.

Jolley’s team processes roughly 20,000 envelopes per month, and he estimates the move to Firma.dev could save between $5,000 and $10,000 over the next year.

“The billing model is like Twilio,” Jolley said. “You just use it and pay for what you send.”

AI-Native Integration Speeds Implementation

The platform’s AI-driven approach also appears to simplify integrations.

Yavuz Selim Mert, founder of Splendid Consulting in Toronto, said he completed a full implementation in roughly a day despite having no prior coding experience.

Using ChatGPT as a guide during setup, Mert reduced his monthly e-signature costs from about $230 with his previous provider to roughly $14 using Firma.dev—an estimated 94 percent cost reduction.

Another customer, Ghali Bennani, co-founder of London fintech startup Ralio, specifically chose the platform for its MCP integration and completed setup in under five minutes.

These examples highlight a growing trend in enterprise software: AI tools increasingly serve as both development assistants and operational interfaces.

Built for AI-First Workflows

Firma.dev’s MCP architecture reflects a broader shift toward AI-driven workflows, where conversational interfaces trigger real business processes across software systems.

Instead of navigating dashboards or writing custom integrations, users can instruct AI agents to perform tasks such as sending contracts, checking document status, or retrieving usage metrics.

This model mirrors developments across the SaaS ecosystem as platforms integrate with AI development tools and agent frameworks.

As AI assistants become more deeply embedded in developer environments and business operations, APIs designed for conversational control may become a defining feature of modern enterprise platforms.

Legal Compliance and Global Availability

Firma.dev’s e-signatures are legally valid in 54 countries and support SES (Simple Electronic Signatures) and AdES (Advanced Electronic Signatures) under the European Union’s eIDAS regulatory framework.

The platform also complies with U.S. electronic signature laws, including the ESIGN Act and UETA, along with equivalent regulations in other supported jurisdictions.

Infrastructure is hosted on European cloud servers, including AWS infrastructure in Paris with content delivery via Stockholm. The system is designed to meet regulatory requirements such as GDPR, HIPAA, SOC 2, and ISO/IEC 27001.

Availability

Firma 12 is available immediately through the company’s website. New users can create an account and begin sending documents without providing a credit card.

Developers and AI tool users can connect to the Docs MCP server or Data MCP server directly, enabling AI-driven document workflows across supported platforms.

As AI interfaces increasingly move beyond chat and into operational control, Firma.dev is betting that e-signatures—one of the most common digital business processes—are ready for a conversational future.
