+## Background
+
+After MCP tools are registered through ToolRegistry, invoking a Yoi MCP-backed tool should call the server's `tools/call` and return a bounded ordinary Tool result. Permission denial must happen before sending a request to the MCP server.
+
+## Requirements
+
+- Route registered MCP tool invocation to MCP `tools/call`.
+- Apply existing PreToolCall / Tool permission path before MCP server call.
+- If permission is denied, do not send `tools/call` to the server.
+- Distinguish normal result, MCP `isError: true`, and JSON-RPC protocol error.
+- Serialize MCP result forms boundedly: `content[]`, `structuredContent`, `isError`, `_meta`, and supported rich content summaries.
+- Store result through ordinary Tool result/history path.
+- Treat all content as untrusted.
+
+## Acceptance criteria
+
+- MCP mock tool returns normal result through ordinary Yoi Tool result.
+- MCP `isError: true` is represented distinctly from JSON-RPC protocol failure.
+- Permission denied call is not sent to the MCP server.
+- Oversize/rich results are bounded/truncated or rejected according to explicit policy.
+- Tool history shows ordinary tool call/result, not hidden context injection.
+- Tests cover normal result, `isError`, protocol error, permission denial, and output bounds.
+
+## Non-goals
+
+- resources/read or prompts/get.
+- list_changed notifications.
+- Sampling/elicitation.
+
+## Related work
+
+- Depends on `00001KVHR3WS6`.
+- Objective: `00001KTR80WMN`.
