## 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: fde_lessons_full (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); fde_catalogue (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); fde_preship_checklist (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); …
- pass `tools.token_cost`: about 544 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`: 1 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: 6, about 544 tokens to load them all
- tool set hash: 2b5e5d54a4a482e0b1ff50488c4b5e41
- tools last changed: 2026-09-25T09:35:55.746Z
- badge: [![protogrid quality](https://protogrid.dev/badge/io.github.IgnatiusTheYoungerAI/fde-lessons-warn-feed.svg)](https://protogrid.dev/servers/io.github.IgnatiusTheYoungerAI/fde-lessons-warn-feed)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-09-25 `pricing_changes` added
  - PAID. Return only the dated Agent Pricing Index corrections at or after a given date — what changed, not the full 47-row dataset. Backed by a monthly re-read against each vendor's own page. Cheaper than fde equivalent full-dataset calls when you only need to know what moved.

## Tools (6)

- `fde_catalogue`: FREE. List every Forward Deployed Engineering rule, playbook, and checklist phase available from this server — id, title, phase, and tags, with the paid body withheld. Call this first to see what is on offer before paying for anything.
- `fde_lessons_full`: PAID. Return the full Forward Deployed Engineering ruleset, or the subset matching a topic. Requires a machine payment (MPP over Stripe). If unpaid, returns the exact payment challenge and the URL to retry against.
- `fde_lessons_preview`: FREE. Return the foundational Forward Deployed Engineering rules in full, no payment required. Each rule carries the real incident behind it and an implementable agent-behavior constraint.
- `fde_playbook`: PAID. Return situational runbooks with ordered, checkable steps — DNS migration and static-site change. Use before executing that class of operation, not after it fails.
- `fde_preship_checklist`: PAID. Return the pre-ship checklist: every gate to clear before shipping, each with the concrete failure it prevents. Designed to be called before every deploy.
- `pricing_changes`: PAID. Return only the dated Agent Pricing Index corrections at or after a given date — what changed, not the full 47-row dataset. Backed by a monthly re-read against each vendor's own page. Cheaper than fde equivalent full-dataset calls when you only need to know what moved.
