Wraps the free mathjs.org API for evaluating mathematical expressions and performing calculations. Good for when you need Claude to handle arbitrary math operations without writing custom evaluation logic. Uses Pipeworx's gateway infrastructure, which hosts 673+ MCP connectors and includes an ask_pipeworx tool that maps natural language questions to the right API calls. No authentication required. The source doesn't enumerate specific tools, but mathjs.org typically handles expression parsing, unit conversions, symbolic computation, and matrix operations. You can connect to just the mathjs endpoint or use the full Pipeworx gateway if you need access to their other data sources.
Math.js MCP — wraps the mathjs.org API (free, no auth)
Part of Pipeworx — an MCP gateway connecting AI agents to 1476+ live data sources.
| Tool | Description |
|---|---|
evaluate | Evaluate mathematical expressions: arithmetic, algebra, trigonometry, statistics. Returns computed result. E.g., "2+2", "sin(pi/2)", "sqrt(16)", "mean([1,2,3])". Use when you need to calculate or simplify math. |
convert_units | Convert between units: length, weight, temperature, volume, time, etc. Returns converted value. E.g., "5 m to ft", "100 kg to lbs", "32 degF to degC". Use for unit conversions. |
Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):
{
"mcpServers": {
"mathjs": {
"url": "https://gateway.pipeworx.io/mathjs/mcp"
}
}
}
tools/list at https://gateway.pipeworx.io/mathjs/mcp returns the tools in the table
above plus the shared Pipeworx meta-tools — ask_pipeworx,
discover_tools, search_within, remember/recall and the rest of the
gateway-wide set. So the tool count you see is larger than this table: a
single-pack endpoint currently lists roughly 30 shared tools alongside the
pack's own. The connection's initialize response states its exact scope, and
is the authoritative answer for a given day.
This is deliberate, not multiplexing by accident. The meta-tools are what let a
scoped connection answer a question this pack does not cover — via
ask_pipeworx, which routes across the whole catalog — without you adding a
second MCP server. There is currently no way to mount a pack endpoint without
them; if the extra schemas cost you more context than the routing is worth,
connect to the full gateway once rather than to several pack endpoints.
Or connect to the full Pipeworx gateway to get every pack's tools listed directly, instead of just this one's:
{
"mcpServers": {
"pipeworx": {
"url": "https://gateway.pipeworx.io/mcp"
}
}
}
Both URLs reach the same gateway and the same 1476+ data sources. The
only difference is which pack's tools are listed directly; ask_pipeworx
reaches all of them from either one.
Instead of calling tools directly, you can ask questions in plain English — this works on the pack endpoint above as well as on the full gateway:
ask_pipeworx({ question: "your question about Mathjs data" })
The gateway picks the right tool and fills the arguments automatically.
