MCP servers configured under mcp.servers are not accessible to the main OpenClaw agent. The built-in image tool always dispatches to the model provider, never to the MCP server.
Environment: OpenClaw v2026.4.26, tools.profile: coding, mcp.servers configured and running.
The MCP server (minimax-coding-plan-mcp) IS healthy - responds to tools/list and returns web_search and understand_image.
Problem: image tool goes directly to Minimax API and fails with 2013 (no vision capability). Agent does not fall back to MCP understand_image tool.
Expected: Agent should use MCP understand_image when built-in image tool fails.
Workaround: mmx vision describe works via shell exec.
This is a follow-up to issue #74387 which was closed claiming already implemented.
