Claude Code, fewer tool calls, smaller bill.
BeagleLathe is a local MCP server for Claude Code. One tool, four actions — search, edit, edit_glob, read — each collapses a 3–5-call Claude Code sequence into one round-trip. Same model, same workflow, smaller token bill.
What it does
Renaming a symbol across three files in Stock Claude Code is roughly twelve tool calls: a glob, a grep, a read per file, an edit per file, a verify-read per file, and usually one failed-edit retry on whitespace drift. Every call's output becomes input tokens on the next turn, so the bill grows faster than the work.
BeagleLathe collapses that same task into two calls. One fused search (glob + regex + ranked snippets). One atomic multi-file edit (fuzzy whitespace and curly-quote tolerance, all-or-nothing dry-run). Twelve calls down to two — −83%.
You keep prompting the way you always have. The agent picks up the collapsed tools automatically.
Measured
Head-to-head against Stock Claude Code on identical tasks, same model on both sides, n=5 across nine fixtures (45/45 verify-pass on both sides — the savings don't come from cutting corners):
~10% cheaper (up to ~19% on multi-file refactors)
~46% fewer tool calls
~29% faster end-to-end wall time
Your code stays on your machine
BeagleLathe runs locally. Source files, search queries, and edit content never leave your laptop. Every Anthropic API request still goes direct from your machine, the same route Stock Claude Code uses. The AST-aware read covers twelve languages — Python, TypeScript, TSX, JavaScript, Rust, Go, Java, C#, Ruby, PHP, C, and C++ — keeping signatures and stubbing function bodies so you don't pay for everything below main().
