Our assessment of mppx

mppx scores 42/100 on our quality scale, 109th of 110 Finance & Accounting skills we index.

Its MCP Server is 10.0 KB long, written without headings and no code examples: a thorough specification that gives an agent plenty to work with.

It has no GitHub stars yet, so there is no community track record; judge it on its content.

Maintenance, license and trust

We could not determine when the repository was last updated.
No license is declared. By default that means all rights are reserved: you can read it, but reusing or redistributing it is not clearly permitted. Ask the author before building on it commercially.
Its trust signals score 68/100, with 3 cautions from licensing, adoption, age or documentation. These come from repository metadata, not a code audit — read the skill file before letting an agent act on it.
