FAQPage Schema
How do I audit MCP server configs for duplicates and schema errors?▼

To audit MCP server configs, run the mcp-check command in your workspace to inventory all project- and user-level entries, surfacing duplicates, misplaced files, JSON syntax errors, and missing schema fields automatically.

What causes a broken MCP config setup in Claude?▼

Broken MCP setups stem from misplaced configuration entries, duplicated servers across files, JSON syntax errors, or invalid mcpServer schemas missing required fields like command, url, args, or env variables.

Can I automatically fix and deduplicate MCP config entries?▼

Yes, you can automatically deduplicate and fix MCP config entries by running the audit command with the --fix flag, which safely relocates misplaced entries and corrects structural issues across workspace files.

Which files are checked during an MCP config audit?▼

An MCP config audit checks project-level paths like .mcp.json, .claude/settings.json, .claude/settings.local.json, alongside user-level configuration locations to unify all entries into a single inventory report.

Why is my MCP server not loading despite being in settings.json?▼

Your MCP server may not load if the settings.json entry has schema violations, such as missing required command or url fields, or if the configuration is misplaced outside expected project or user-level paths.
