## Trust

- hygiene: 100
- liveness: 99
- freshness: 85
- provenance: 75
- drivers: +repository +dns-namespace +reachable +uptime-97% ~updated-62d-ago
- 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 2025-06-18; 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: save_document_template (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_offerings (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); render_document (readOnlyHint, destructiveHint, idempotentHint, openWorldHint)
- pass `tools.token_cost`: about 509 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: 3, about 509 tokens to load them all
- tool set hash: 6be54477fe900d81a5393a951a621624
- badge: [![protogrid quality](https://protogrid.dev/badge/net.01mind/charon.svg)](https://protogrid.dev/servers/net.01mind/charon)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (3)

- `list_offerings`: Free. Everything 01Mind offers, on demand rather than loaded into your context upfront. section: "catalogue" (every purchasable listing with its price and the exact tool name to call it by -- most are callable but not advertised), "documents" (the full render_document schema, limits and templates), "venue" (open live-research studies you can take part in), or "all".
- `render_document`: Produce a real .docx or .xlsx file from structured content and return it as base64. Send format ("docx"|"xlsx") plus exactly ONE of: blocks (array of {type:"title"|"heading"|"text"|"mono"|"table", text, level?, headers?, rows?}), markdown (string), sheets (array of {name, rows:[{...}] or rows:[[...]] with columns:[...]}), or templateId + values. Optional filename. Free for the first 5 documents a month on an API key sent as X-API-Key, then $0.25 per document via x402 -- an unpaid call over that returns a real HTTP 402 challenge. Dry run free at POST /sandbox/execute/render-document. Full schema and limits: call list_offerings with section "documents".
- `save_document_template`: Free, and does not use your document allowance. Store a reusable layout once so you stop re-sending it: send format, blocks (or sheets), an optional templateId, with {{placeholders}} where values go, and a table may carry rowsFrom:"listName" to repeat one row over an array. Then render with { templateId, values }. Requires an API key (X-API-Key). Saves a large layout from being re-sent on every call, which is usually the single largest avoidable cost in a request.
