io.github.jdhart81/taxcredit-engine MCP Server

This MCP server provides auditable US clean-energy tax-credit scenarios for 45Q, 45V, 45Y, 48E, and 45X. It targets a carbon and compliance workflow spanning five steps—measure, account, disclose, claim, and scan—implemented as paid HTTP routes and returns structured JSON responses.

🛠️ Key Features

Auditable US clean-energy tax-credit scenarios for 45Q, 45V, 45Y, 48E, 45X
Workflow coverage: measure → account → disclose → claim → scan
Tool count: 5
Readme excerpt indicates seven deterministic paid HTTP routes, with MCP security preflight and receipt handling

🚀 Use Cases

Scenario generation and validation for specific US clean-energy tax credits (45Q, 45V, 45Y, 48E, 45X)
End-to-end carbon and compliance workflow support across the five named steps

⚡ Developer Benefits

Structured JSON outputs plus a payment receipt per execution (per excerpt)
Deterministic paid routes with verification and settlement before execution

⚠️ Limitations

Paid HTTP routes are described; a first paid call for a new wallet is $0.01, with other pricing “unchanged”
The readme excerpt mentions seven routes, while the provided toolCount is 5

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)

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.
