Regen for AI

Add Regenerative AI to your Claude Code in 30 seconds.

Every AI session consumes energy. This MCP server lets your AI assistant estimate that footprint and retire verified ecocredits on Regen Network — with immutable on-chain proof.

This is regenerative contribution, not carbon offsetting. No neutrality claims. Just verified funding of ecological regeneration.

Install

claude mcp add -s user regen-for-ai -- npx regen-for-ai

That's it. Works immediately — no API keys, no wallet, no configuration needed for read-only tools.

Other MCP clients (Cursor, Windsurf, etc.)

Add to your MCP config:

{
  "mcpServers": {
    "regen-for-ai": {
      "type": "stdio",
      "command": "npx",
      "args": ["regen-for-ai"]
    }
  }
}

What You Get

Tool	What it does
estimate_session_footprint	Estimate energy, CO2, and retirement cost for your AI session
browse_available_credits	Browse live sell orders on Regen Marketplace (carbon, biodiversity, marine, species)
retire_credits	Retire credits on-chain (with wallet) or get a credit card purchase link (without)
get_retirement_certificate	Verify any retirement with on-chain proof
get_impact_summary	Regen Network aggregate stats — projects, retirements, jurisdictions
browse_ecobridge_tokens	List 50+ tokens across 10+ chains for cross-chain payment
retire_via_ecobridge	Pay with USDC/ETH/etc. on Ethereum, Base, Polygon, Arbitrum, and more

Three payment modes — pick what works for you

1. Credit card (default, no setup) — get a Regen Marketplace link
2. Direct on-chain — set REGEN_WALLET_MNEMONIC, retire in a single tx
3. Any token, any chain — USDC on Base, ETH on Arbitrum, etc. via ecoBridge

How It Works

Your AI Assistant (Claude Code / Cursor / etc.)
    │
    │ MCP Protocol (stdio)
    ▼
Regen for AI MCP Server
    │
    ├─ Footprint estimation (heuristic, clearly labeled as approximate)
    ├─ Credit browsing (live sell order data from Regen Ledger)
    ├─ Retirement execution (MsgBuyDirect with auto-retire)
    └─ Certificate retrieval (on-chain verification)
    │
    ▼
Regen Network Ledger (immutable, verifiable, non-reversible)

If anything fails during on-chain retirement, it falls back to a marketplace link. Users are never stuck.

Configuration

Works with zero config. Set environment variables for advanced features:

cp .env.example .env

Variable	Required	What it enables
(none)	—	Footprint estimation, credit browsing, impact stats, marketplace links
REGEN_WALLET_MNEMONIC	Optional	Direct on-chain retirement (MsgBuyDirect)
ECOBRIDGE_EVM_MNEMONIC	Optional	Cross-chain payment via ecoBridge (send USDC, ETH, etc.)
ECOBRIDGE_ENABLED=false	Optional	Disable ecoBridge tools

See .env.example for all options with inline documentation.

MCP Prompts

Pre-built workflows you can invoke:

Prompt	Workflow
offset_my_session	Estimate footprint → browse credits → retire
show_regen_impact	Pull live network stats and summarize
retire_with_any_token	Browse ecoBridge tokens → pick chain/token → retire

Credit Types

Type	Description
Carbon (C)	Verified carbon removal and avoidance
Biodiversity (BT)	Terrasos voluntary biodiversity credits
Marine Biodiversity (MBS)	Marine ecosystem stewardship
Umbrella Species (USS)	Habitat conservation via umbrella species
Kilo-Sheep-Hour (KSH)	Grazing-based land stewardship

Data Sources

Source	What it provides
Regen Ledger REST	Credit classes, projects, batches, sell orders
Regen Indexer GraphQL	Retirement certificates, marketplace orders, stats
Regen Marketplace	Credit card purchase flow
ecoBridge API	Cross-chain tokens, prices, widget links
