Nothing serious here today

Today is the operative word: we check FlipLetters every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

flipletters

flipletters_create_animation

One call from plain text to a FlipLetters video: builds a board on a text template (default minimal), checks the text against FlipLetters content rules, cloud-renders an MP4 under the signed-in owner's plan (free renders carry the FlipLetters watermark), and returns mp4Url (downloadable HTTPS), shareUrl (opens in Studio), jobId, status and expiresAt. If the render is still running when this returns, poll flipletters_render_status with jobId. Not idempotent: each call starts a new render and counts against the plan's render quota; poll render_status instead of calling again. If a call fails or times out, confirm with the user before retrying.

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. Not idempotent: each call starts a new render and counts against the plan's render quota; poll flipletters_render_status instead of calling again. If a call fails or times out, confirm with the user before retrying.

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. Posts publicly to the connected social account when not drafted; confirm the destination and caption with the user before calling. Not idempotent: each call creates another post. If a call fails or times out, confirm with the user before retrying.

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. Not idempotent: each call adds another copy of the board to the Team Library. If a call fails or times out, confirm with the user before retrying.

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.

FlipLetters — questions

Answers built from our own checks of this server.

What can FlipLetters do?

It exposes 13 tools, read directly from the server on our last check. Among them: flipletters_create_animation, flipletters_example_board, flipletters_flipcode_reference, flipletters_list_postiz_destinations, flipletters_list_postiz_integrations, flipletters_list_teams and 7 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is FlipLetters working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 375 ms. The bar chart above shows every period we have measured.

How do I connect FlipLetters?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does FlipLetters need an API key?

No. FlipLetters completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 13 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is FlipLetters?

It answers our handshake in 375 ms on average, which is faster than 35% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

How many people use FlipLetters?

The npm package flipletters-mcp-server was installed 47 times in the last week. Week over week that is +1433%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is FlipLetters open source?

The code is open source: it is published under the MIT licence and 0 stars on GitHub. The licence covers the code in the repository, not the hosted service at app.flipletters.com, which runs on its operator's own terms.
