MCP Server: legal-grade certification for AI agents

Your AI agents call certification tools natively, with zero custom code. Connect in minutes.

TrueScreen’s MCP Server is the first Model Context Protocol implementation designed for data certification with legal validity. Compatible with Claude, ChatGPT, Gemini, and LangChain-based agents, the server exposes certification as a native tool that agents call autonomously during their workflows.

As the EU AI Act requires traceability for AI-generated content, organizations need a mechanism to certify what an AI agent produced, when, and from which data. TrueScreen’s MCP Server creates this immutable audit trail without changes to the agent’s core logic.

Connect

Add the TrueScreen MCP server to your agent. One configuration file, no custom code.

Call

Your agent calls native tools: certify files, submit hashes, create workflows, retrieve reports.

Certify

Every output sealed with digital signature and qualified timestamp. Court-ready.

Certify every layer of your AI agent lifecycle

Four levels of legally binding certification, from knowledge base to output.

TrueScreen addresses EU AI Act transparency requirements by certifying every layer of the AI agent lifecycle: from the knowledge base consulted, to the prompts and instructions used, to the operations performed, to the final output delivered.

Each layer receives a digital signature and qualified timestamp, creating proof of existence for every data point the agent touched. This four-level approach produces a complete, court-admissible audit trail that satisfies regulatory obligations under eIDAS, GDPR, and the Product Liability Directive.

Knowledge Base

Certify the exact data your agent consulted at the moment of access.

Prompts

Immutable proof of system prompts, instructions, and configurations.

Operations

Every tool call, reasoning step, and decision as a legal audit trail.

Output

Every result sealed with qualified timestamp and digital signature.

Frequently Asked Questions

What is the TrueScreen API?
TrueScreen, the Data Authenticity Platform, provides a RESTful API that lets you integrate legally valid data certification into any system. Certify files, submit hashes, manage workflows, retrieve reports, and monitor credits programmatically. All certifications include a digital signature and qualified timestamp from an EU-accredited trust service provider, compliant with eIDAS. Integration typically takes less than a day with full documentation and code examples.
What is MCP and how does it work with AI agents?
MCP (Model Context Protocol) is an open standard that lets AI agents call external tools natively. TrueScreen's official MCP Server gives any compatible AI agent the ability to certify data with full legal value, directly from its reasoning pipeline, with zero custom code. This creates an immutable, court-admissible audit trail of every AI operation: what was generated, when, and from which data sources.
Which AI platforms support TrueScreen MCP?
Claude (Anthropic), ChatGPT (OpenAI), Gemini (Google), LangChain, and any agent framework that supports the MCP standard. Integration takes minutes.
Does API and MCP certification have legal value?
Yes. Every certification includes a digital signature and qualified timestamp from an accredited EU trust service provider, fully compliant with eIDAS Regulation. Qualified timestamps carry legal presumption of accuracy across all 27 EU member states. Evidence produced by TrueScreen is admissible in court across Europe and internationally.
How long does integration take?
API integration typically takes hours with full documentation and code examples. MCP integration takes minutes: add the server configuration and your agent can immediately call certification tools.
Can I certify AI agent outputs for regulatory compliance?
Yes. TrueScreen certifies data across four levels of the AI agent lifecycle: knowledge base, prompts, operations, and outputs. Each level receives a digital signature and qualified timestamp, producing proof of existence for every data point. This supports compliance with the EU AI Act (traceability for high-risk AI systems), the Product Liability Directive, GDPR, and DORA.
What does certification cost?
TrueScreen uses a credit-based system. Credits are consumed per certification. Enterprise plans include volume pricing, full API and SDK access, and dedicated support.
Is there a sandbox or test environment?
Yes. You can test the API and MCP integration with free credits included in every new account.
