v0.1.0

mcpshell — a sandboxed JS-syntax scripting language that gives LLMs safe computation through a single eval tool.

First tagged release. The parser, runtime, interpreter, all toolkits (core, math, web, file, graph, SQL, browser), the MCP server, and the LLM benchmark harness are implemented and tested — 750+ tests, 33/33 benchmark teasers passing.

Install

go install github.com/iodesystems/mcpshell/cmd/mcpshell@v0.1.0

Drops a mcpshell binary in your $GOBIN. ✓ Verified — this command fetches v0.1.0 from the published module and builds a working binary in a clean environment.

Run without installing

go run github.com/iodesystems/mcpshell/cmd/mcpshell@v0.1.0 '[1,2,3] |> map(x => x * 10)'

Requires Go 1.26+ — the module's go directive auto-fetches the toolchain for anyone on Go 1.21 or newer. No Java is needed; the generated parser is committed.
