How it works

Powered by MCP (Model Context Protocol) - the open standard for AI tool integration

Step 1

Connect

Integration in minutes, not in months

Add Prevector to any MCP-compatible AI system such as ChatGPT, Claude, Gemini or your own GPT application. MCP (Model Context Protocol) is an open standard that lets AI systems access external tools without custom integrations. No API wrappers. No middleware. No modifications to your existing stack. Just add our server endpoint to your MCP configuration and your AI gains structured access to professional standards.

Step 2

Query

Hybrid search with paragraph-level precision

Your AI queries our structured standards database using hybrid search combining semantic understanding with keyword matching. Ask natural questions or search for specific provisions. The system understands both. Every query returns results at the paragraph level, not just document titles. When your AI asks about disclosure requirements, it gets the exact paragraphs that answer the question not a vague pointer to a 200-page standard.

Step 3

Cite

Every answer traceable to its source

Every response includes complete citations: standard name, paragraph number, and exact source text. Your AI does not just give answers, it shows its work. Citations link directly to official source documents. When a client questions a finding, you can trace it back to the authoritative text in seconds. No more "the AI said so", now it is "ESRS E1 paragraph 35 requires this."

Built for precision

Every component designed for audit-grade accuracy

Integration

Simple AI integration

Prevector connects via MCP (Model Context Protocol), the open standard for AI tool integration. Add structured standards access to ChatGPT, Claude, Gemini, or any AI-system in minutes. No custom development, no middleware, no changes to your existing setup.

Data quality

Framework tailored

Every standard is parsed, structured, and indexed specifically for AI retrieval. We do not just convert regulations, we build optimised semantic paragraph-level databases with cross-references, definitions, and hierarchical relationships intact.

Security

Secure by design

Prevector runs as a separate service with no access to your AI's context or outputs. Query data is not logged or stored. Deployment options include cloud-hosted or private infrastructure for maximum control.

Accuracy

Advanced retrieval

Hybrid search combining semantic understanding with keyword precision. 97% accuracy in benchmark testing. Results ranked by relevance with configurable thresholds for your specific use case.

Verification

Complete citations

Each response returns the exact paragraph reference, section hierarchy, and document source. No hallucinated citations, every output is traceable to official published standards.

Currency

Frequently asked questions

What teams typically ask before getting started.

What is an MCP server?

MCP (Model Context Protocol) is an open standard for connecting AI systems to external tools and data. Each Prevector MCP server provides structured access to one standards framework (e.g., CSRD or Dutch tax laws) that your AI can query directly.

Which AI systems are compatible?

Prevector works with any AI system that supports MCP, including ChatGPT, Claude, Gemini, other GPT-based systems, and custom AI implementations. No modifications to your existing AI stack are required.

How does pricing scale?

Pricing is based on two factors: the number of MCP servers you need and your API usage tier. Higher tiers include more API calls per month. You can upgrade or add servers at any time.

What's included in implementation?

Implementation services include integration support, configuration for your AI environment, testing, and a training session for your team. This is available as a one-time service separate from your subscription.

Can I try before committing?

Yes. Contact us to discuss a pilot arrangement. We offer flexible trial periods for qualified organizations to evaluate Prevector with their specific use cases.
