MCP Server

freeno auth read-onlyv0.7.0

This URL is a hosted Model Context Protocol server. It gives AI assistants live, calibrated predictions and meta data (tier lists, counters, synergy, ban rates, momentum) for competitive games, served by batru.gg's game-specific production models. The current public tool catalog covers Dota 2, Deadlock and Marvel Rivals. Each predictor is evaluated in its own game context; the public Dota 2 evaluation ledger is one example of that evidence.

Notes

Read-only and stateless: no Batru account or API key is required.
Hosted calls are logged by default for usage analytics, tool-quality improvement, error diagnosis and abuse prevention. Logs may include IP address, client information, tool inputs and outputs, agent-provided intent, duration and errors. The local uvx batru-mcp stdio package does not send this MCP tool-call telemetry; its requests to the public Batru API remain subject to ordinary server logs. See the privacy policy.
Numbers are for draft analysis, not betting advice.
