## Quality 74/100 (needs work)

### 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: why_surfaced (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_commitments (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); draft_reply (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 543 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: 50 (weight 15)

- warn `deps.known_vulns`: 1 advisory of lower severity or without a published fix: GHSA-5r4p-p66f-jhc7 in hono@4.13.9 (indirect, fixed in 4.13.11)
- fail `deps.mcp_sdk_version`: @modelcontextprotocol/sdk 1.30.1 has 3 known advisories (GHSA-22jm-h49p-29qw, GHSA-6prh-2h8m-c8cw, GHSA-6qxp-vccf-f47h); update @modelcontextprotocol/sdk to 1.32.0 or later
- pass `deps.resolvable`: radmail-mcp@0.5.0 resolved: 98 packages

- tools: 6, about 543 tokens to load them all
- tool set hash: 1677901541a5a0a5d711f7903a1e5183
- badge: [![protogrid quality](https://protogrid.dev/badge/ai.radmail/radmail-mcp.svg)](https://protogrid.dev/servers/ai.radmail/radmail-mcp)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (6)

- `draft_reply`: Draft a reply for a thread. It returns text for a human to review — it does not and cannot send it.
- `list_commitments`: Extract the open commitments in the correspondence, both owed by you and owed to you, with who and by-when.
- `list_right_now`: Return only the 'Right Now' lane — the most recent and most important messages that genuinely can't be missed.
- `search`: Find a specific message by sender, subject, or content. Results come back most-relevant + newest first, and every hit says where it matched (from / subject / body) and why. On this hosted sandbox it searches the built-in demo inbox; run the radmail-mcp package with RADMAIL_API_KEY set and the same tool searches your REAL ingested inbox read-only (with from / after / before filters) via the v1 search API.
- `triage_inbox`: Rank a mailbox on two axes (importance x urgency) and return what needs a human now versus what can wait or is already handled — with each thread's open commitment (the promise you owe or are owed, and whether it's overdue) surfaced inline, so the follow-through is visible on the very first call.
- `why_surfaced`: Explain in plain English why a given message was surfaced — the signals (sender, urgency, commitment) behind its rank.
