+== AI tool attribution
+
+Kobiton records which AI tool made each MCP call, and stores that name on sessions started with `startNativeSession`. The server resolves the name from the request itself, so no tool accepts it as an argument and no prompt or skill has to supply it.
+
+The server checks, in order:
+
+. The `X-AI-Tool-Name` header, when your MCP server configuration sets it.
+. The `User-Agent` sent by your AI assistant, when the header is absent.
+. `Unknown`, when neither identifies a recognized tool.
+
+An unrecognized value never fails a call. The call runs normally and Kobiton records the tool as `Unknown`.
+
+Set `X-AI-Tool-Name` to attribute your calls explicitly. The Codex CLI and Cursor CLI setup guides already include this header in their MCP configuration examples. See xref:mcp/install-local-ai-plugin.adoc[Install and configure local plugin] and xref:mcp/cursor-cli.adoc[Kobiton for Cursor CLI].
