- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 4 of 4 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 704 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

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

- n/a `stability.changes`, `stability.rug_pull`: tool history not recorded yet

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

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

- tools: 4, about 704 tokens to load them all

## Tools (4)

- `elucora_attest`: Prove a piece of content existed at a point in time by sealing its SHA-256 hash. Use when you already hold the bytes — a model output, a tool result, a document. Elucora records that you submitted this hash and when; it does not prove where the content came from or that it is true, because Elucora never saw the source. To prove what a web source served, use elucora_capture instead. Consumes receipt quota.
- `elucora_capture`: Freeze proof of what a web source actually served, before quoting or acting on it. Returns a signed receipt that anyone can verify offline without trusting Elucora. Proves what was served and when, not that the content is true. Sends a network request to the supplied source and consumes receipt quota.
- `elucora_get_receipt`: Fetch an evidence receipt by ID: the source it covers, the exact passage or field that was sealed, the current signature result, and its transparency log and Bitcoin anchor state. Needs no credentials.
- `elucora_verify`: Check whether an evidence receipt is genuine and unaltered, and what source bytes it covers. Use this before relying on a receipt produced by someone else. Needs no credentials.
