The Dart and Flutter MCP server: one command to give Claude Code your running Flutter app

Fix: HTTP MCP Server URL Won't Connect in Claude Desktop (stdio vs HTTP Transport)

Claude Desktop's claude_desktop_config.json only validates stdio servers. Drop a 'url' field in and it silently strips the entry, crashes on startup, or boots with zero tools. Use a custom connector for remote URLs and mcp-remote as a stdio bridge for local HTTP servers.

How to fix it in Claude Code 2.1.x with ENABLE_TOOL_SEARCH and alwaysLoad, on the raw API with the tool search tool and defer_loading, and on the MCP connector with mcp_toolset. Anchored to claude-opus-4-7, claude-sonnet-4-6, and the 20251119 tool search variants.

Fix: Extra Inputs Are Not Permitted on a Tool Call With a Structured Argument

Your agent's tool call fails with Pydantic's 'Extra inputs are not permitted'. The model added a field your structured argument forbids. Turn on strict tool use so the grammar blocks it, relax the validator, or recover in the loop.

Fix: `ECONNREFUSED` When a Local MCP Server Starts Before the Client Is Ready
