Nothing to run from here
forthling is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.

What it does
Run Forth-2012 in a sandbox: definitions stay between calls, each result shows the stacks.
Quickstart
Install it the way its author documents:
1. cargo install forthling-mcp --version 0.2.5

Installation
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. This one runs on your machine: your client starts forthling as a process under your own user, with your files and your network, so the tool surface below is what it can do to your computer rather than to a server somewhere else. Its scan result is on the Security tab — read the surface before you approve it.

Tool surface
What the model actually sees. Descriptions are diffed on every release — see version history.
Read from its source code. A server that builds its tool list when it starts can list more tools than this.
Runs Forth-2012 code in the session and returns what it printed, the data stack and the float stack, and the error if there was one. Definitions, variables, files and the stacks stay for the next call. Large input goes in data, which the code reads with DATA; source files to INCLUDE go in files.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| code | string | yes | Forth source; it may have several lines, each at most 1024 characters |
| trace | boolean | no | If true, the result also gives a trace: each word that ran (not inside the built-in words), with how deep it was nested and the data stack when it started; at most 1000 words. For finding where code g |
| data | string | no | Text for the word DATA ( -- c-addr u ), which gives a copy in ALLOCATEd memory (FREE it); without a line limit, for large input such as JSON. It stays for later calls until another call sends data. |
| files | object | no | Files to put in the session's file system before the code runs, as {"name": "text"}, replacing files of the same name; the code can INCLUDE them or open them with the FILE words. The files are in memo |
Shows the data stack and the float stack, without running anything.
No parameter schema on file.
Lists the words defined in this session, the latest first (not the built-in words).
No parameter schema on file.
Starts a new Forth session: every definition, variable and stack value is gone, and so are the data and the files.
No parameter schema on file.

ATrust score 93 / 100
Release 0.2.4 · scanned 9 Nov 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 surfacenot available
Implementation sourceread
Package metadataread
Live transportnot available
No tools were enumerated, so prompt-injection, capability and toxic-flow analysis had no tool surface to inspect. To grade a package’s real runtime tools, scan the running server: --command "npx -y <package>".
Capability — what it could do if the model were manipulated
Tags derived from each tool’s schema and the implementation, not from what the tool calls itself. high is the level these add up to.

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.

This is the first scan of this surface here, so there is nothing yet to compare it against.
Every result on this tab comes from one deterministic pass over the published package — offline, rule by rule, and auditable line by line above. Same methodology version, same bytes, same score.
Release history
It installs from its repository rather than from a versioned package, so the command cannot be pinned to a release. The history below is for reading; the current release on file is 0.2.4.

Who can review
One review per account, from a signed-in account that does not publish this listing. Nothing else is asked — you can say what you think before you install it. Publishers can reply once per review, and a review can be edited or deleted by whoever wrote it.
Sign in to write one
Any signed-in account that does not publish forthling can review it, once — before installing it or after. A review from an account that has installed it is marked as one.
No reviews yet
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes a signed-in account that does not publish it, and nothing else.
