  "$comment": "Project metadata for the 4A Claude.ai Remote MCP connector. As of 2026-04, Claude.ai has no published manifest schema — paid users install custom connectors by pasting `mcpServerUrl` into Settings → Connectors → Add custom connector. This file documents the connector for the project, future Anthropic directory submission, and user-facing docs at /surfaces/claude-connector. Field names mirror the directory-listing fields (name, description, mcpServerUrl, iconUrl, categories, support) that Anthropic has been collecting from third-party connectors.",
