## Quality 92/100 (new)

### 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: 93 (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
- pass `tools.annotations`: 12 of 12 tools declare readOnlyHint or destructiveHint
- warn `tools.directory_hints`: 3 of 12 tools declare all four hints; missing: flipletters_validate_board (destructiveHint); flipletters_example_board (destructiveHint); flipletters_list_teams (destructiveHint); …
- pass `tools.token_cost`: about 2,000 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 recorded for 3 of the 7 days needed

### dependencies: 100 (weight 15)

- pass `deps.known_vulns`: no known advisory in 100 resolved packages
- pass `deps.mcp_sdk_version`: @modelcontextprotocol/sdk 1.32.1, no known advisory
- pass `deps.resolvable`: flipletters-mcp-server@0.3.1 resolved: 100 packages

- tools: 12, about 2,000 tokens to load them all
- tool set hash: 5faa6a6dad9f171e4ab642f3de600c02
- badge: [![protogrid quality](https://protogrid.dev/badge/com.flipletters/mcp.svg)](https://protogrid.dev/servers/com.flipletters/mcp)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (12)

- `flipletters_example_board`: Returns a complete, valid flipcode document for a board type (minimal, trainboard/station, artboard, flipdot, marquee, announcement, arena) — a known-good starting point to edit rather than writing from scratch.
- `flipletters_flipcode_reference`: Returns the flipcode cheat sheet (spec v1): directives, board types and size limits, transition modes, and flip-native effect recipes. Call this before writing a board so the code you produce is valid on the first try.
- `flipletters_list_postiz_destinations`: Lists Postiz destinations (masked keys) attached to a FlipLetters project. Use flipletters_list_workspaces first. Requires Authorization: Bearer flk_….
- `flipletters_list_postiz_integrations`: Lists connected social channels for a project's Postiz share account. Use before flipletters_share_to_postiz to get integrationId. Requires Authorization: Bearer flk_….
- `flipletters_list_teams`: Lists FlipLetters teams the API key owner belongs to (teamId, name, inviteCode). Requires Authorization: Bearer flk_… with team scope.
- `flipletters_list_workspaces`: Lists agency projects (workspaces) for the API key owner, plus the active project id. Project-scoped keys return their bound project as active. Requires Authorization: Bearer flk_….
- `flipletters_render_board`: Parses flipcode and submits a cloud MP4 render under the API key owner's FlipLetters plan (same free quota / Premium / Studio limits as the Studio). Requires Authorization: Bearer flk_… (or FLIPLETTERS_API_KEY on stdio). Polls until done (or returns jobId if wait=false). Prefer share links for free previews; only render when the human wants an MP4 file.
- `flipletters_render_status`: Poll a cloud render job started with flipletters_render_board. Requires Authorization: Bearer flk_….
- `flipletters_share_to_postiz`: Uploads a cloud media URL (or Studio host local fileName) to a project's Postiz destination and schedules/drafts/posts it. Loop: render_board → list_workspaces → list_postiz_destinations → list_postiz_integrations → share_to_postiz. Requires Authorization: Bearer flk_…. Prefer mediaUrl from flipletters_render_board.
- `flipletters_share_to_team`: Parses flipcode and shares the board into a Team Library the key owner is a member of. Requires Authorization: Bearer flk_…. Use flipletters_list_teams first to get teamId.
- `flipletters_template_url`: Builds a human-readable FlipLetters Studio URL where every query parameter mirrors one flipcode line — good for short text boards you want legible in the address itself (chat messages, docs). For full fidelity or paint grids use flipletters_validate_board's share link instead. Slides are strings with | between rows.
- `flipletters_validate_board`: Parses a flipcode document, returning the normalized canonical code, any warnings (out-of-range values are clamped, unknown lines ignored), a board summary, and links: a share URL that opens the exact board in the FlipLetters Studio, and an open-with-code URL that also reveals the code panel. Use this after drafting a board; fix warnings and re-validate until clean, then give the human the share link.
