No change was recorded against any check on this day. Stability & Change Management went from 80 to 83. That category is still filling its 30-day observation window: 24 days of observed history at the previous scan, 25 at this one. The score rises as the window fills, whether or not the server changes.

Provenance No attestation
The registry publishes no build provenance for this version, so there is nothing to verify.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

What is the io.github.kendall8388/keyframe MCP server?
io.github.kendall8388/keyframe is an MCP server listed in the public MCP registry as io.github.kendall8388/keyframe. Animate 2D skeletons in Keyframe.it, pixel sprites in Sprite Puppeteer, 3D rigs in MeshForge. This page covers its npm package (keyframe-mcp).
Is the io.github.kendall8388/keyframe MCP server safe to use?
io.github.kendall8388/keyframe scores 75 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 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 65 tools: keyframe_open, keyframe_methods, keyframe_call, keyframe_screenshot, keyframe_session, and 60 more. Their descriptions and schemas cost roughly 3,642 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 5 November 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.
What did VerifyMCP test on the io.github.kendall8388/keyframe MCP server?
VerifyMCP ran 15 checks on io.github.kendall8388/keyframe, covering Malware scan, Known CVEs, Install scripts, Dependency health and 11 more. One item could not be completed, a gap on our side rather than a finding about io.github.kendall8388/keyframe: Security disclosure. Endpoint Security and Transport & Reachability do not apply to an npm package, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
