Feature & Specification Comparison

Specification	Codex MCP Tool x51xxx Coding Agents	Glm MCP djerok Coding Agents
Summary	MCP server that connects your IDE or AI assistant to Codex CLI for code analysis and editing with support for multiple models (gpt-5-codex, o3, codex-1)	Run GLM (Zhipu/Z.ai) as a real sub-agent inside Claude Code or GitHub Copilot. GLM gets its own agent loop (read/write/edit/run) on your repo — not a single LLM call — with peak-aware Opus-vs-GLM routing, diff/dry-run/git-revert oversight, and a usage ledger. 10x cheaper than Opus. Requires a Z.ai GLM Coding Plan key.
