### `keyframe_methods` (~24 tokens)

List scripting methods; read recipes through keyframe_call for rigging workflows.

### `keyframe_call` (~47 tokens)

Call a scripting method using positional arguments. Read keyframe_methods first. Mutations are saved; image results appear inline.

Input parameters:

- `args` (array)
- `method` (string, required)

### `keyframe_screenshot` (~22 tokens)

Input parameters:

- `animation` (string)
- `samples` (integer)
- `size` (integer)

### `keyframe_check_animation` (~47 tokens)

Check endpoint discontinuities, sampled invisible parts and rig problems. Warnings can be intentional; also review rendered frames.

Input parameters:

- `animation` (string)
- `samples` (integer)

### `keyframe_export` (~79 tokens)

Write an editable project JSON, animated GIF or Spine ZIP to disk. Returns an MCP resource and local path. Spine ZIP includes atlas, textures and a preview.

Input parameters:

- `animation` (string)

Show one image layer as a PNG.

Input parameters:

- `asset` (string, required)
- `id` (string, required)

io.github.kendall8388/keyframe scores 68 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 20 September 2026. It declares no install or post-install scripts. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the io.github.kendall8388/keyframe MCP server expose?

io.github.kendall8388/keyframe exposes 18 tools: keyframe_open, keyframe_methods, keyframe_call, keyframe_screenshot, keyframe_session, and 13 more. Their descriptions and schemas cost roughly 737 tokens of context every time the server is loaded.

### Is the io.github.kendall8388/keyframe MCP server still maintained?

io.github.kendall8388/keyframe is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the io.github.kendall8388/keyframe MCP server under?

io.github.kendall8388/keyframe declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
