Credit-card-calibrated visual measurement — the first sellable service.

Captured live from the server via tools/list.

credit_card_photo_instructions

Return user-facing capture instructions for credit-card calibrated measurement. Use this before asking for a photo. The user should place a standard credit/debit card flat in the same plane as the target objects.

measurement_goal	string	optional
objects_to_measure	any	optional

scale_objects_from_credit_card

Scale object pixel dimensions using a standard CR80 credit card reference. Args: image_id: Unique photo identifier. credit_card_pixel_width: Pixel width of the visible credit/debit card. objects: Objects to scale. Each object needs pixel_width and pixel_height; label, pixel_area, pixel_perimeter, and confidence are optional. credit_card_pixel_height: Optional card pixel height for distortion check.

Viridis Agent Fleet — MCP Surface

The public MCP-facing surface of the Viridis agent stable: a 13-agent agent-to-agent (A2A) economy published on the Model Context Protocol registry under the earth.viridis namespace. This repository is the callable spec + provenance for those listings — the registry manifests, the JSON-Schema tool definitions, the public agent contracts, and the reference gateway. The agent cores are maintained privately; everything here is what a calling agent needs.

By Viridis LLC — conservation technology.

The economy: identity → trust → escrow → settlement → constitution

Trustworthy agents transacting with agents needs rails. This fleet ships them as composable MCP services:

Layer	Agent	What it provides
Identity	`agent-identity-registry`	Content-addressed agent DIDs + capability discovery — the passport + directory
Trust	`agent-trust-oracle`	Decay-weighted reputation + tamper-evident trust attestations
Settlement	`agent-escrow`	Trustless escrow with an exactly-once state machine + audit hash chain
Metering	`agent-metering`	Usage metering + SLA accounting — the meter behind x402
Arbitration	`agent-arbitration`	Dispute-resolution oracle consuming trust signals
Compute ledger	`agent-compute-ledger`	"Compute is carbon" cost/energy accounting for agent work
Covenant	`agent-covenant`	Deny-by-default authority leases for agents wielding real power
Provenance	`agent-provenance`	Genesis certificates, lineage, cascading recalls
Offsets	`agent-offset-clearinghouse`	Verified-credit carbon accountability — the conservation flywheel
Revenue	`smartscale`	Credit-card-calibrated measurement — the first sellable service
Revenue	`protogen`	MCP CAD services; bundles with SmartScale (measure → CAD)
Revenue	`regulatory-radar`	CSRD/TNFD compliance-as-a-service
Enabler	`narrative-engine`	Grant / investor / policy narrative generation

Calling an agent

Every agent is a streamable-HTTP MCP server hosted behind https://mcp.viridis.earth/<path>/mcp (paths in each server.json). Point any MCP client at the URL, or discover them on the registry by searching earth.viridis. Each tools.json is the exact tool surface — one tool per agent action, with typed input/output schemas.

Status

LIVE (2026-07-09). All 13 published on the MCP registry under io.github.jdhart81/* and hosted at https://viridis-agent-stable.fly.dev (/healthz = 13 ok). The as-shipped manifests are in mcp-publish-github/ (the mcp-publish/ set holds the branded earth.viridis variants for the round-1b rebrand + custom domain mcp.viridis.earth).

Round-1 posture: endpoints are open (read-tool posture); no funds move — escrow, offsets, and metering are state machines, with payment rails (x402 for A2A, Stripe for human-facing services) attaching in a later round. See docs/A2A_ECONOMY.md.
