## Quality 63/100 (needs work)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-06-18; 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: verify (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); dpp_readiness_check (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); scan_living_qr (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 1,021 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 25 (weight 15)

- warn `stability.changes`: 16 tool changes in 30 days
- fail `stability.rug_pull`: 6 tools kept their name but changed most of their description in 30 days; review before trusting them

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

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

- tools: 6, about 1,021 tokens to load them all
- tool set hash: f686e88e22ee96d115d6bf67b9d104b5
- tools last changed: 2026-10-17T15:51:38.100Z
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.undone0603/authichain.svg)](https://protogrid.dev/servers/io.github.undone0603/authichain)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-10-17 `scan_living_qr` added
  - Free. Scan a stored Living QR. GET https://authichain.com/qron/r/{object_id} returns AuthiChain Verification Decision v1. This host verifies the signature. A missing id is presentation_not_found. Not an x402 payment endpoint, and it does not inspect a physical product.
- 2026-10-17 `verify` changed (description, inputSchema)
  - before: Legacy x402 seal verify, not answering. Unpaid tools/call returns HTTP 402 for discovery; a paid call is refused with 503 registry_not_bound before settlement, so no payment is taken. For free verification use verify_record.
  - after: Legacy x402 seal verify, not answering. Arguments that cannot be a seal UUID are HTTP 400 before payment. Empty arguments are unpaid HTTP 402 for discovery; a paid call is refused with 503 registry_not_bound before settlement, so no payment is taken. For free verification use verify_record.
- 2026-10-10 `verify_record` changed (description)
  - before: Free. Verify an AuthiChain signed provenance record with the open reference verifier, then read its Polygon anchor transaction. Pass id "polygon-anchor-1" for the published demonstration record, anchored on Polygon mainnet in tx 0x2491…10b7, or pass your own record and anchor JSON. Returns verified, valid-unanchored, or invalid, plus whether the transaction carries the record hash. It does not inspect a physical product.
  - after: Free. Verify an AuthiChain signed provenance record with the open reference verifier. Pass id "polygon-anchor-1" for the published demonstration record, or pass your own record and anchor JSON. Returns verified, valid-unanchored, or invalid, plus whether the transaction carries the record hash. It does not inspect a physical product.
- 2026-10-08 `query_provenance` changed (description) **meaning changed**
  - before: Free public lookup for an assetId / seal / QR token. Never attests. Unknown IDs return status unknown. For free signature and anchor verification use verify_record.
  - after: Free public lookup for an assetId / seal / QR token. Never attests. Resolves the published packs (bat-2026-001, trumark, musa, strainchain); any other id returns status unknown, because the certificates registry does not answer yet. For free signature and anchor verification use verify_record.
- 2026-10-04 `verify_record` added
  - Free. Verify an AuthiChain signed provenance record with the open reference verifier, then read its Polygon anchor transaction. Pass id "polygon-anchor-1" for the published demonstration record, anchored on Polygon mainnet in tx 0x2491…10b7, or pass your own record and anchor JSON.

- 2026-10-04 `query_provenance` changed (description) **meaning changed**
  - before: Free public lookup for an assetId / seal / QR token. Never attests. Unknown IDs return status unknown. Paid tools/call verify ($0.05 USDC on Base) is not answering yet: it refuses before settlement.
  - after: Free public lookup for an assetId / seal / QR token. Never attests. Unknown IDs return status unknown. For free signature and anchor verification use verify_record.
- 2026-10-04 `verify` changed (description)
  - before: Paid AuthiChain verification, not answering yet. Unpaid tools/call returns HTTP 402 ($0.05 USDC on Base) for discovery; a paid call is refused with 503 registry_not_bound before settlement, so no payment is taken. Use query_provenance for a free lookup.
  - after: Legacy x402 seal verify, not answering. Unpaid tools/call returns HTTP 402 for discovery; a paid call is refused with 503 registry_not_bound before settlement, so no payment is taken. For free verification use verify_record.
- 2026-10-04 `get_pricing` changed (description) **meaning changed**
  - before: Live AuthiChain prices: StrainChain Passport, Farm, and EU DPP Payment Links for humans; unpaid POST /api/x402 ($0.05 USDC on Base) for agents.
  - after: Free. AuthiChain verification is free: use the verify_record tool, or GET https://authichain.com/api/verify. Paid plans are on hold, so no prices or Payment Links are listed.
- 2026-09-28 `dpp_readiness_check` added
  - Free EU Digital Product Passport readiness check. Returns a 0-100 score, gaps, and the dated obligation for the product category (battery passport is law from 18 Feb 2027; other categories are ESPR targets). Not legal advice.
- 2026-09-28 `query_provenance` changed (description)
  - before: Free public lookup for an assetId / seal / QR token. Never attests. Unknown IDs return status unknown. Cryptographic verify is tools/call verify ($0.05 USDC on Base).
  - after: Free public lookup for an assetId / seal / QR token. Never attests. Unknown IDs return status unknown. Paid tools/call verify ($0.05 USDC on Base) is not answering yet: it refuses before settlement.
