## Scope

Local reference pinned to MCP 2025-11-25. Supports initialize, notifications/initialized, ping, tools/list and tools/call. No HTTP, authentication, resources, pagination or production systems. Tool annotations are hints, not authorization. Use a maintained MCP SDK and application authorization for a production integration.

Bundled data is synthetic. Source and tests are included; see LICENSE for terms. This is not proprietary model source or the production Axis framework.
