MCP Local
truecalc · MCP server
TrueCalc Local is a native MCP server built on TrueCalc's spreadsheet document engine. It gives your AI assistant more than 70 tools to read and edit cells, formulas, formatting, charts, pivots and more. The package is a thin wrapper that starts the prebuilt program for macOS (arm64 or x64), Linux (x64) or Windows (x64), and Linux arm64 is not yet published. TrueCalc Local is a paid product with a one-time licence of $49, and every tool call except licence activation is blocked until a valid licence is cached on your machine.

Why it's useful
Your agent can open and change spreadsheet documents itself, with formulas, formatting, charts and pivots within reach.
What you could do with it
- Have your agent read the cells and formulas in a spreadsheet document.
- Ask your agent to change values and formatting in a spreadsheet.
- Have your agent work on the charts and pivots in a spreadsheet.
Written from its documentation: what it says it can do, not what our checks found.
Maintenance
Not measuredNo release date is on record for this package yet. The nightly publisher check records one as it reaches each npm package, about once every ten nights.
Release activity only: it says nothing about quality or safety, and a finished small package can be fine without releases. How it is measured
- Command execution is bounded
- inventory
- node child_process (bin/truecalc-mcp-local.js:6)
- synchronous shell execution (bin/truecalc-mcp-local.js:52)
- 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.
- Licence and provenance
- finding
- no LICENCE file at the root (.)
- Data handling disclosed
- finding
- no statement of what it reads, writes or sends (README.md)
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.

In its maker's words

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 1.0.7, the file with digest sha512-WxOhFi/9qTFMXxJjF/IEVvQKqT1fJmprwT1YYMJ5SXnIuP7EymukLDb5YniTMnGxlEcxc9oNWKXc3y5kRreVgw==, as the registry publishes it. A published version cannot be replaced, so this names the same bytes for anyone who checks.
- Authentication
- Runs locally. No hosted endpoint is listed for this package. You run it on your own machine, so there is no endpoint of ours to authenticate against.

No build provenance published. The repository above is the one the publisher declared, and nothing links it to the package you would install. That is not a mark against this listing, since most packages are published this way, but it is a check nobody can run.
