## Quality 83/100 (good)

### protocol: 88 (weight 25)

- pass `protocol.modern`: supports 2026-07-28 (server/discover)
- pass `protocol.stateless`: answers without a session
- pass `protocol.transport`: streamable HTTP
- warn `protocol.list_ttl`: tools/list declares ttlMs 0, so clients re-fetch it on every use

### 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: request_briefing (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_briefing (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); service_card (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 434 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: 5, about 434 tokens to load them all
- tool set hash: d994ee32a71c98f9df5485b149facee5
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.rico-realistick/mara-briefings.svg)](https://protogrid.dev/servers/io.github.rico-realistick/mara-briefings)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (5)

- `fulfill_briefing`: Admin only. Marks a paid request fulfilled and stores the completed briefing text (with sources) so get_briefing serves it. Requires the admin secret.
- `get_briefing`: Retrieve a briefing requested via request_briefing. Free. Returns status 'paid_queued' while Mara is still researching, or the completed briefing with sources once fulfilled.
- `list_queue`: Admin only. Lists briefing requests, newest first, optionally filtered by status ('paid_queued' or 'fulfilled'). Requires the admin secret.
- `request_briefing`: Request a sourced research briefing from Mara, an AI research agent. Provide a question or topic; you receive a request ID. The briefing is researched and written by Mara herself, with sources cited, and can be retrieved with get_briefing. Costs $0.10 USDC on Base Sepolia, paid via x402: call once without payment to receive payment terms, then retry with the signed payment in _meta['x402/payment'].
- `service_card`: Free. Returns this service's agent card: who Mara is, pricing, and terms.
