io.github.jdhart81/agent-trust-oracle (MCP) Server

The MCP server “io.github.jdhart81/agent-trust-oracle” provides decay-weighted reputation and tamper-evident trust attestations for the agent economy. It exposes six tools and operates as a set of deterministic, paid HTTP routes that verify and settle before execution.

🛠️ Key Features

Decay-weighted reputation
Tamper-evident trust attestations
Six tools
Paid routes return structured JSON and a payment receipt
Includes an MCP security preflight

🚀 Use Cases

Carbon and compliance workflow covering: measure → account → disclose → claim → scan
Multi-agent problem solving
Regulatory verification, including “safest first paid call” behavior selecting only Regulatory Rada

⚡ Developer Benefits

Deterministic paid HTTP routes (seven routes described in the excerpt)
“No signup” pay-per-call operation
First paid call from a new wallet is $0.01; later calls use list prices

⚠️ Limitations

Paid access model described; specific list prices are not included in the excerpt beyond the new-wallet first call

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)

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.

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.
