On 2026-10-28 the server answered initialize and tools/list without a sign-in. First answer in 228 ms.

• Its tools do every use case we checked: turn a typed message into a split-flap video; make station departure board clips with mechanical sound.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

• 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…

• flipletters_example_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.
