Toolint is a structural linter for Python packages, not an MCP server. It exposes 9 linting rules as CLI commands, not as MCP tools. No tool definitions with schemas, descriptions, or parameters are visible in the source. The tools listed (check_core_stdlib_only, check_optional_import_guard, etc.) are Python functions in rule modules, not registered MCP tool definitions. No input schemas, output schemas, or parameter descriptions exist. This is a standalone CLI application, not an MCP-compatible tool server.

• Convert Toolint to an MCP server by implementing the MCP protocol (HTTP or STDIO transport) and registering each linting rule as a proper MCP tool with name, description, input schema, and output schema.
• Expand tool descriptions from single sentences to 50 - 200 characters explaining WHAT the rule checks, WHEN to use it, and WHAT violations mean. Example: 'Verifies that core/ directory imports only stdlib modules. Prevents accidental third-party dependencies in core logic. Returns list of non-stdlib imports found.'
• Define input schemas for each tool specifying the project path, optional rule filters, and output format. Use JSON Schema with type definitions and descriptions for all parameters.
• Document output schemas showing the structure of linting results: rule ID, severity, file path, line number, violation description, and remediation hint.
• Add error recovery guidance: when a rule violation is detected, include a specific fix suggestion. E.g., 'check_optional_import_guard violation: numpy imported without try/except. Wrap with: try: import numpy\nexcept ImportError: raise ImportError("Install with: pip install pkg[numpy]")'
