The harness that produced these numbers is described below; its repository is not public at the moment, so take the figures as reported rather than as independently verifiable. A re-measurement was published here on 2026-08-09 and has been withdrawn on 2026-08-10. It reported new-token savings from a small replacement harness. Those numbers did not measure this server at all: across 143 benchmark sessions, exactly one called a Token Savior tool. The client running the harness had MCP deferred-tool loading enabled, so all 18 tools sat behind a ToolSearch lookup instead of appearing in the model's manifest. The model never saw them and fell back to Grep and Read — 66 greps, 30 reads, one MCP call. What varied between the \"profiles\" was the size of the cached prefix, not what the agent did. The lesson is worth more than the numbers were: a benchmark of an MCP","default_branch":null,"files":null,"tree":[],"storefront":"/r/Mibayy","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/Mibayy/token-savior/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
