## Findings

No check matched anything in these tool definitions.


## Changes things (1)

Creates or changes something that can be changed back. Claude Code: ask.

### `record_evidence`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
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.
```

## Only reads (7)

Looks things up and changes nothing. Claude Code: allow.

### `get_chain`

- The name "get_chain" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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 name "get_checkpoint" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
The log's signed checkpoint in the C2SP format witnesses cosign (origin, size, root).
```

### `get_consistency_proof`

- The name "get_consistency_proof" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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 name "get_evidence_head" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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`

- The name "get_inclusion_proof" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
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 name "get_ledger_attestation" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
The signed head hash of the hash-chained audit ledger of recorded quotes.
```

### `get_usage`

- The name "get_usage" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
How much is recorded, and by how many keys that are not ours. Counts only, nothing about anyone.
```
