Filtered out: Atomic Chat and Atomic (Knowledge Graph) were excluded because they mention MCP integration but are not primarily MCP tools themselves; Octomind was filtered out as it's primarily a testing platform with CI/CD focus rather than an MCP-focused tool; several non-open-source entries like SonarQube and Wiz were excluded per the open-source requirement.

Filtered out: Several tools like OpenClaude and Oh My OpenAgent were excluded because while they're open source, they don't specifically focus on MCP functionality. Other tools like CSS Studio and Stitch were filtered out because they're design-focused rather than MCP-specific. Desktop Commander was considered but not included as it's freemium rather than fully open source.
