## Quality 86/100 (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: 100 (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
- pass `tools.annotations`: 8 of 8 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 954 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 75 (weight 15)

- warn `stability.changes`: 10 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: 8, about 954 tokens to load them all
- tool set hash: 63fe845132164ab1b29fc77c4a5b3d2f

- badge: [![protogrid quality](https://protogrid.dev/badge/eu.riskrouter/evidence-log.svg)](https://protogrid.dev/servers/eu.riskrouter/evidence-log)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

  - The log's signed statement of one completeness chain as of the current head: its length and, for each position, the leaf, the time and the digest. A position nobody showed you is a record left out.

## Tools (8)

- `get_chain`: The log's signed statement of one completeness chain as of the current head: its length and, for each position, the leaf, the time and the digest. A position nobody showed you is a record left out.
- `get_checkpoint`: The log's signed checkpoint in the C2SP format witnesses cosign (origin, size, root).
- `get_consistency_proof`: Proof that the tree at size first is a prefix of the tree at size second (or now): the log never rewrote history.
- `get_evidence_head`: The current signed head of the evidence log: tree size, Merkle root and signature. Save it: any later head must be consistent with it.
- `get_inclusion_proof`: Proof that the entry at leaf_index is in the tree, optionally at a given tree_size. Checkable offline with the public verifier.
- `get_ledger_attestation`: The signed head hash of the hash-chained audit ledger of recorded quotes.
- `get_usage`: How much is recorded, and by how many keys that are not ours. Counts only, nothing about anyone.
- `record_evidence`: Record the SHA-256 of a decision record you keep yourself, so it can later be shown to be unchanged. Send the digest and a short kind, never the record. Needs your RiskRouter key in the Authorization header of the MCP connection. Entries are permanent.
