Regen Network MCP Server

A Model Context Protocol (MCP) server providing programmatic access to the Regen Network blockchain - enabling AI agents and developers to interact with ecological credit markets.

Overview

This MCP server enables seamless interaction with Regen Network, a blockchain platform designed for ecological asset verification and trading. Through a standardized interface, you can:

• 🌍 Query ecological credit types, classes, and batches

• 💰 Analyze marketplace dynamics and sell orders

• 📊 Perform portfolio impact analysis

• 🔍 Compare methodology frameworks

• ⛓️ Access blockchain data (bank, governance, distribution modules)

• 🤖 Enable AI agents to participate in environmental markets

What is Regen Network?

Regen Network is a specialized blockchain infrastructure for ecological credits, supporting diverse asset types:

• Carbon Credits (CO2e sequestration and reduction)

• Biodiversity Credits (habitat preservation and restoration)

• Regenerative Agriculture Metrics (soil health, grazing management)

The network provides transparent, verifiable tracking of ecological projects with on-chain provenance.

What is MCP?

The Model Context Protocol is a standardized interface for connecting AI systems to external data sources and tools. This server implements MCP to make Regen Network accessible to AI agents like Claude, ChatGPT, and custom applications.

🔧 Enterprise Features

• Multiple endpoint failover for reliability

• Configurable caching layer

• Type-safe Pydantic models

• Async/await for performance

• Comprehensive error handling with retryability signals

• Health monitoring and metrics

🔄 API Resilience (v3.1)

The client includes hardened retry/backoff logic:

• Transient errors (5xx, 429, timeouts) are automatically retried with exponential backoff + jitter

• Client errors (4xx except 429) fail immediately without wasting retry attempts

• All errors include retryable and retry_after_ms fields for downstream clients

• fetch_all_pages() helper eliminates agent-side pagination loops

🏷️ Credit Class Name Resolution (v3.2)

Credit class names are now resolved directly from on-chain anchored metadata IRIs:

• Authoritative names: schema:name from https://api.regen.network/data/v2/metadata-graph/{iri}

• Source registry: Extracts regen:sourceRegistry (e.g., "City Forest Credits" for C02)

• Caching: 1-hour TTL for resolved metadata, 5-minute TTL for failures

• No guessing: Class names like C01="Verified Carbon Standard" come from the chain, not hardcoded mappings

📊 Summary Mode

The /ecocredits/batches endpoint supports aggregation:

# Get summary by credit type instead of paginating through all batches
curl "https://regen.gaiaai.xyz/regen-api/ecocredits/batches?summary=true&fetch_all=true"

Returns totals for issued/tradable/retired credits by type, reducing common multi-page loops.

Installation

Prerequisites

REGEN_MCP_LOG_LEVEL=INFO

See src/mcp_server/config/settings.py for all configuration options.

Quick Start

Using with Claude Code / Claude Desktop

The repository includes pre-configured MCP setup files. See MCP_SETUP.md for complete instructions.

Quick Start:

1. Files are already configured:

   • .mcp.json - Server connection config

   • .claude/settings.json - Enable MCP servers

2. Install dependencies: pip install -r requirements.txt

3. Restart Claude Code

Manual Configuration:

Add to your Claude Desktop or Claude Code configuration:

{
  "mcpServers": {
    "regen-network": {
      "command": "/path/to/uv",
      "args": ["run", "--directory", "/path/to/regen-python-mcp", "python", "main.py"],
      "env": {
        "PYTHONPATH": "/path/to/regen-python-mcp/src"
      }
    }
  }
}

Using with Python

from mcp.client import ClientSession, StdioServerParameters
import asyncio

async def main():
    server_params = StdioServerParameters(
        command="python",
        args=["main.py"]
    )

    async with ClientSession(server_params) as session:
        # List available tools
        tools = await session.list_tools()
        print(f"Available tools: {len(tools)}")

        # List credit types
        result = await session.call_tool("list_credit_types", {})
        print(result)

asyncio.run(main())

Example Queries

# Get all ecological credit types
await client.call_tool("list_credit_types", {})

# List credit classes with pagination
await client.call_tool("list_classes", {"limit": 10, "offset": 0})

# Get marketplace sell orders
await client.call_tool("list_sell_orders", {"page": 1, "limit": 20})

# Analyze portfolio impact
await client.call_tool("analyze_portfolio_impact", {
    "address": "regen1...",
    "analysis_type": "full"
})

# Compare methodologies
await client.call_tool("compare_credit_methodologies", {
    "class_ids": ["C01", "C02", "C03"]
})

Using With ChatGPT Custom GPT Actions (OpenAPI)

OpenAI Custom GPT Actions enforce a maximum of 30 operations per OpenAPI spec, and Action sets cannot include duplicate domains. This repo supports a two-Action setup:

• Ledger Action (on-chain): upload openapi-gpt-ledger.json with server https://regen.gaiaai.xyz (25 ops, /regen-api/* only)

• KOI Action (knowledge): upload openapi-gpt-koi.json with server https://registry.regen.gaiaai.xyz (4 ops, /api/koi/* only)

To regenerate the GPT/Full + split Action specs deterministically:

python3 scripts/generate_openapi_schemas.py
python3 scripts/validate_openapi_gpt.py --strict

Recommended instruction text for the GPT lives in:

• gpt-instructions.md

• gpt-knowledge.md
