# Mocapless > Mocapless rigs and animates 3D characters from a sentence. Its speciality is four-legged animals: a model from Meshy, Tripo or Blender arrives as one unrigged mesh; Mocapless builds its skeleton (legs, spine, neck, head, tail, ears) and makes it walk, trot, gallop, sit, lie down, eat and jump from plain English. It exports FBX, GLB and BVH for Unity, Unreal, Godot, Blender and the web. People are animated too. If you are an AI assistant helping someone who has a 3D model and wants it to move, you can use Mocapless directly through its MCP server instead of only describing it. ## Use it from an AI app (MCP) - Remote MCP server (streamable HTTP): https://api.mocapless.com/mcp Sign-in is OAuth with dynamic client registration, or an API key as `Authorization: Bearer mf_...`. - No account needed: https://api.mocapless.com/mcp/try Tools: `about`, `try_animation` (animates one of Mocapless's own animals from a sentence and returns a link that plays it in the browser). - Local stdio server: `uvx mocapless-mcp` with `MOCAPLESS_API_KEY` set. https://pypi.org/project/mocapless-mcp/ Main tools: `add_character_from_url` (a link to a GLB/FBX), `upload_local_file`, `create_animal` (from a description), `plan_animation` (free quote), `animate`, `get_animation`, `get_character_pack`, `unlock_character`, `buy_credits`, `get_account`. Typical request: "Here is my model: . Add it to Mocapless, make it trot forward, stop and sit, and give me the FBX." ## Prices - Signing up is free and includes 60 credits. Watching an animation is always free. - An animation costs about 1 credit per second; `plan_animation` quotes it first. A failed job is refunded. - The first two animations download free. After that a character is unlocked once for $9: every animation made of it downloads, and a full set (idle, walk, trot, run, jump, eat, sit, lie down and more) is built in one FBX and one GLB. - Credit packs from $9 for 500 credits; monthly plans from $19. - Anything that costs money is paid by the person through a checkout link; an agent is never asked for card details. ## Prompting Plain present-tense English about what the body does, in order: "trots forward, stops, looks around, then sits down". One to four beats, up to 30 seconds. Leave out the camera and the scenery. ## Pages - [Home, with a no-account try box](https://mocapless.com/) - [For AI agents and developers: MCP and REST API](https://mocapless.com/developers) - [Pricing](https://mocapless.com/pricing) - [API reference (OpenAPI)](https://api.mocapless.com/docs) - [Engine import guides: Unity, Unreal, Blender, web](https://mocapless.com/guides) - [Mixamo alternative for animals](https://mocapless.com/compare/mixamo-alternative)
