Stop paying tokens to rebuild solved problems. One call tells your agent which listed tool is cheapest and reachable, and what you save vs building it. Free, no login. Install the MCP server.
get_result picks the cheapest measured-reachable tool.build_or_buy compares your token forecast to published per-call prices.cost_estimate.json_validate.tool_status shows 7-day reachability and latency.curl "https://dirtsmith-go.bfurrow26.workers.dev/get_result?intent=web+search&est_tokens=20000&usd_per_mtok=3&calls=100"

Every get_result returns a receipt inline, for example: intent "web search", 100 calls, est. build $6.00 (20k tokens × $3/M) vs Exa published $0.007/call = $0.70, est. savings $5.30. Estimates from your inputs and published prices; nothing is charged.
Dirtsmith-built tools return real results. Outside tools are called directly by you at their endpoints; Dirtsmith does not proxy them. Paid use through Dirtsmith is not live and may never launch.
