**An agent can connect right now, no human step.** Remote endpoint, no authentication, reachable on the last probe.

## Connection (mcpServers)

```json
{
  "mcpServers": {
    "ghg-ledger": {
      "type": "http",
      "url": "https://mcp.viridisconservation.com/ghg-ledger/mcp"
    }

## Trust

- hygiene: 60
- liveness: 100
- freshness: 65
- provenance: 80
- drivers: +repository +namespace-matches-repo +reachable +uptime-100% ~updated-99d-ago -duplicate-repo(32 names)
- Derived from observable signals (official registry feed and our own credential-free probes); no code audit performed.

## Quality 79/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 71 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: describe_agent (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); calculate_inventory (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_factor_pack (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 602 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: no tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 6, about 602 tokens to load them all
- tool set hash: 2a199fbf5f89674ed884904bdc25c8da
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.jdhart81/ghg-ledger.svg)](https://protogrid.dev/servers/io.github.jdhart81/ghg-ledger)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (6)

- `calculate_inventory`: Calculate an auditable GHG inventory from explicit activity records.
    Returns per-line gas/CO2e results, Scope 1/2/3 and category rollups, dual
    Scope 2 reporting, indeterminate lines, factor lineage, notary payload, and
    an offset-clearinghouse dry-run weave. This is calculation, not advice.
    Price: $1.00 per call after 10 free calls/day. Pay at
    /x402/ghg-ledger/calculate_inventory with Base USDC, cash-fund payment_ref
    through escrow_checkout + confirm_escrow_funding, or use /seats.
- `classify_activity`: Suggest scope and Scope 3 category from the bundled deterministic map.
    No inference is used; unknown activity types return no suggestion.
- `describe_agent`: Return fleet-standard capabilities, version, pack digest, and pricing.
- `get_factor_pack`: Return factors, GWP values, conversions, sources, and pack SHA for one
    exact bundled region/year. No nearest-region or nearest-year substitution.
- `list_factor_packs`: List the bundled pack version/digest, supported regions and years,
    activity types, GWP set, and explicit MVP coverage.
- `verify_result`: Recompute a prior inventory's audit hash and conservation checks. Pass
    the prior result object as JSON; tampering or stale factor lineage is flagged.
