io.github.jdhart81/narrative-engine (MCP Server)

This MCP server generates grant, investor, and policy narratives for conservation work. Its description frames narrative generation as the core capability, and the readme excerpt specifies autonomous pay-per-call tools built around a carbon and compliance workflow.

🛠️ Key Features

Name: io.github.jdhart81/narrative-engine
Generates narratives for conservation work: “Grant, investor & policy narrative generation”
ToolCount: 2
Payment-based HTTP routes and structured JSON responses
Supports a five-step carbon and compliance workflow: measure → account → disclose → claim → scan
Includes multi-agent problem solving and an MCP security preflight
Paid routes verify and settle before execution; returns payment receipt

🚀 Use Cases

Generating conservation-related narratives for grants, investor communications, or policy contexts
Running the carbon and compliance workflow steps: measure, account, disclose, claim, scan

⚡ Developer Benefits

Deterministic, paid HTTP routes covering the workflow steps
Structured JSON output plus a payment receipt
Security preflight included for MCP

⚠️ Limitations

Tooling described is pay-per-call (“x402/USDC on Base”); first call from a new wallet costs $0.01
Route-level pricing and the “Safest first paid call” constraint are described, including a selection behavior (“only Regulatory Rada”)

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.
