Section 01

AstraNL MCP Overview (Main Guide)

AstraNL MCP is an EU-hosted MCP server that aggregates 15 ready-to-use AI capabilities from multiple top providers (Anthropic, OpenAI, Gemini, Grok). Key features include pre-paid wallet with micro-EUR billing, GDPR compliance, zero-profit inference, and full support for the MCP protocol to standardize AI-tool interactions.

Project Background & MCP Protocol Basics

MCP (Model Context Protocol) was launched by Anthropic in late 2024 to solve the fragmentation issue of AI-tool integration. Its core values: standardized interface (unified tool description/call format), dynamic discovery (AI auto-detects available tools), bidirectional communication (tools return structured data), and security control (clear permissions). AstraNL MCP is built on this protocol to aggregate multi-provider AI services.

Core Capabilities & Multi-Provider Architecture

15 AI Capabilities

Covers text generation (translate, write, code), text processing (summarize, classify, extract), and others like Q&A, paraphrase, grammar check, etc.

Multi-Provider Grid

Provider Representative Models Features
Anthropic Claude 3.5 Sonnet, Claude 3 Opus Strong reasoning and coding capabilities
OpenAI GPT-4o, GPT-4 Turbo Extensive application ecosystem
Google Gemini 1.5 Pro, Gemini Ultra Ultra-long context window
xAI Grok Real-time information access

Smart Routing

  • Ability Matching: Task-specific model selection (e.g., code generation uses Claude/GPT-4, long docs use Gemini)
  • Failover: Auto-switch to backup providers on outages
  • Cost Optimization: Choose economical models for simple tasks

Unified MCP Interface

Exposes consistent MCP endpoints regardless of underlying providers (e.g., tools/list, tools/call).

Billing Model & Compliance

Billing

  • Prepaid Wallet: Flexible top-up, no subscription fees, transparent consumption details
  • Micro-EUR Billing: Precise per-token charging (0.000001 EUR granularity), no minimum consumption
  • Zero Profit: Only covers actual provider costs, no hidden fees

EU Compliance

  • Data Residency: All data stays in the EU economic area
  • GDPR Alignment: Data minimization, purpose limitation, user rights (access/correction/deletion) supported
  • Enterprise-Friendly: Meets regulatory requirements for compliance-focused businesses

Section 06

Limitations & Future Directions

Limitations

  • Third-Party Dependency: Service quality depends on underlying providers (API changes/failures affect service)
  • Prepaid Risks: Idle balance, potential refund complexity
  • MCP Ecosystem: Limited clients and evolving protocol

Future Plans

  • Add more providers (Cohere, AI21)
  • Expand to multi-modal capabilities (image/audio)
  • Support user-customized fine-tuning
  • Add enterprise features (SSO, audit logs, SLA)
  • Edge deployment options
