Quickstart

Install it the way its author documents:

1. Download Surehand-MCP.mcpb and open it in Claude Desktop or another client that installs MCP bundles (.mcpb) 2. Its sha256 is ee7482e810f3c8dcda25a1862315f1575d652842c9ce999618cb7bfc6153bd71

Tool surface

What the model actually sees. Descriptions are diffed on every release — see version history.

Only tools that write or reach the network

Read from its source code. A server that builds its tool list when it starts can list more tools than this.

Restructure precomps without changing the picture, with every expression reference rewritten exactly and pixel proof. unprecompose:

Parameter	Type	Required	Notes
action	string	yes	—
comp		yes	unprecompose: the comp that holds the precomp layer; deep_duplicate: the comp to copy with its tree. Default: the active comp.
layer		no	unprecompose: the precomp layer (index or name; default the selected layer).
id	string	no	remove_copies: the copy set id a deep duplicate returned (default: the latest one made in this project).
dryRun	boolean	no	Only plan: what would move, be renamed and rewritten, and every blocker. Nothing is changed.
removeSource	boolean	no	unprecompose: also remove the source comp, only if nothing else uses it (refused otherwise). Default: keep it.
bakeNull	boolean	no	unprecompose: leave out the null when the precomp layer's transform is the identity (exact); otherwise a null is kept and the result says why.
suffix	string	no	deep_duplicate: added to each copy's name (default " copy"; a number is added when the name is taken).
folder	string	no	Not supported: After Effects records every move into a folder as an undo step of its own, so the copies stay next to their originals. Move them afterwards with ae_move_items.
override	array	no	Go ahead despite these problems (they are still reported, left as they are, and the pixel proof decides): expressions = references that can't be rewritten safely; bounds = layers that reach outside th

ATrust score 93 / 100

Release 1.4.1 · scanned 28 Oct 2026

Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.

score = clamp(round(threatScore − E_cap − E_ver − E_cov), 0, 100). No model, no opinion, no network call at scoring time: the same methodology version against the same bytes always produces this number, and every line above is a field of the report rather than a summary of it.

What the scan could actually read

A grade is only as meaningful as its coverage, so the scanner publishes its own depth before it publishes its result.

Tool surfaceread

Implementation sourceread

Live transportnot available

Tools were statically extracted from the published source (23 recovered), not enumerated from a running server. Tool-poisoning, Unicode-smuggling, capability and toxic-flow analysis ran on this inferred surface, but a mis-parsed registration could be missed or mis-attributed, so tool-derived findings are capped below “confirmed”. To grade the real runtime surface, scan the running server: --command "npx -y <package>".

Toxic-flow graph

The lethal trifecta, checked as a graph rather than as a checklist: untrusted input, a sensitive source and an external sink have to meet before there is a path worth worrying about.

The public result for this release does not print the flow graph, so there is nothing to show here. That is not the same as "no paths were found": what the scan did read is above, under coverage.
