What else was checked

Publisher and name

Nothing found across 5 checks run. Checked 2026-10-02.

Maintenance

Maintained

Last release 24 Aug 2026 (5.0.0), 38 days before this check on 2 Oct 2026.

Read from the npm registry's publish history, read by the nightly publisher check.

Release activity only: it says nothing about quality or safety, and a finished small package can be fine without releases. How it is measured

Not yet tested
Command execution is bounded
inventory
node child_process (src/cli.js:11)
node child_process (scripts/token-cli.js:162)
synchronous shell execution (scripts/token-cli.js:186)
synchronous shell execution (scripts/token-cli.js:187)
An inventory of where the code starts another program, not a verdict on this row: whether each one runs a fixed program or whatever it is handed takes a reading by hand.
Tool description integrity
no match, 5 read
Pattern set 1.0 matched nothing across 5 descriptions, read 2026-10-07.
It reads the descriptions the package ships, not what the server says when it runs, and a clean description is not the same thing as a safe tool.

Published because it was found. A finding is information about where the limits are, not a verdict that the software is unsafe.

What this does not cover

  • ·Everything. Treat it as you would software from anywhere else.

Tool descriptions are read with pattern set v1.0, published with every rule, its sources and how often it has been wrong.

Receipt history: every signed receipt for every version of this listing, and what changed between them.

What it does

Catch up on Slack without reading it. Unreads, threads, search. Browser-session or hosted OAuth.

How far this has been checked

Static scanned

What it establishes
Its published package, or for a hosted server its source repository at a recorded commit, was read file by file, without running it, by every check in our current scan.
What it does not
How it behaves when it runs, or anything the scan does not read yet: several rubric checks, the repository's history, and compiled code in folders named dist or build. For a hosted server, that the endpoint runs the code that was read. The ooruby Index sets out exactly what was read.
Exactly what was read
Version 5.0.0, the file with digest sha512-rAwifxp5yOnCqaUf9tE8qDv08mAozdBZLEWURMo1LkNNPZq8kl34YWOfCEKoNjZ23abuvPxAvo2+JOAx1TD2tw==, as the registry publishes it. A published version cannot be replaced, so this names the same bytes for anyone who checks.
Authentication
No auth declared. Its hosted endpoint, as the official MCP registry lists it, does not say it asks for a key. That is what the listing declares, not a finding that it has no protection.
How the rungs work

The badge, if this is your listing

It renders the current rung (static scanned) and links back here, where what that does and does not establish is one click away. It updates itself as the evidence deepens.
