Overview

AI-generated overview

Wjttc is a local stdio MCP server described as an "F1-grade MCP certification" suite of 52 tests across 9 tiers, including receipt validation.

What you can do
  • The listing gives no tool list, so capabilities are inferred from the description only.
  • It presents itself as a certification suite for MCP, running 52 tests across 9 tiers.
  • 49 of the tests are described as scored, with a ninth tier covering receipt validation.
  • It is referenced as part of an ecosystem entry (#2759).
When to use it
Only worth considering if you want to run a described MCP certification test suite locally; the listing gives no detail on what the tests check or what output they produce.
Requirements
Runs as a local process over stdio, installed from the npm package wjttc, so a Node.js runtime is needed. Desktop client only; no web execution. No authentication, environment variables or headers are declared.
Before you install
The description is very sparse: no tools, README or instructions are provided, so what the tests actually do and what data they touch cannot be verified. Review the package before running it locally.

Installation

In SourceWeft

  1. Open Wjttc in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

SourceWeft started this package once in an isolated sandbox, without credentials, to list its tools. That failed: the server did not start.

Score

25% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.

  • Tools listed15 pts

    Answer tools/list without a credential, or ship a package that starts in a sandbox without one.
