io.github.jdhart81/ghg-ledger — Model Context Protocol (MCP) Server

This MCP server provides deterministic Scope 1/2/3 GHG inventories with bundled factors and audit hashes. It exposes six tools/HTTP routes supporting a carbon and compliance workflow, and returns structured JSON results.

🛠️ Key Features

Deterministic Scope 1/2/3 GHG inventories
Bundled factors
Audit hashes
Tooling available via six routes
Readme indicates structured JSON responses and payment receipts for paid routes

🚀 Use Cases

Measure → account → disclose → claim → scan carbon and compliance workflow
Verifying and settling before execution for paid calls
Multi-agent problem solving
MCP security preflight referenced by the readme excerpt

⚡ Developer Benefits

Structured JSON outputs (per readme excerpt)
Audit hashes to support auditing
Deterministic inventory generation

⚠️ Limitations

Source excerpt only describes paid autonomous tools and workflow steps; it does not document configuration, authentication details, or full tool schemas beyond the stated intent.

Viridis Agent Fleet: open-source agents for the agent economy

Deterministic, auditable MCP agents: trust and settlement rails (identity, trust, escrow, metering, arbitration, notary, surety, provenance, covenant, offsets, compute-ledger) and priced-grade services (tax credits, GHG accounting, construction takeoff, measurement, compliance). Every core is pure Python with no LLM in the serving path, and every result is content-addressed so anyone can re-verify it.

Licensed Apache-2.0. Run any agent yourself, fork it, embed it.

Or use the hosted fleet

https://mcp.viridisconservation.com runs all agents as one managed MCP service:

Self-hosted (this repo)

Hosted by Viridis

Agent logic & verification

✅ identical

Viridis-signed receipts & notary chain

–

✅

Shared trust/reputation network data

–

✅

Maintained rule packs (tax, GHG factors, regs)

snapshot

✅ kept current

Payments (x402, card), seats, SLA

–

✅

Free tier: 10 calls/day per service; the rails (identity, escrow, metering…) are free forever. Verification is always free.

Boundary

This repo contains agent cores, MCP adapters, tests, standards and self-host tooling. The hosted service layer (gateway, payment and settlement, seats, signing authority, operations, telemetry and customer data) is proprietary and is not in this repo. Please don't open PRs that add it.
