Feature: MCP server and tool health manager

[slashdevcorpse]

Research-backed TODO

Codex CLI users often rely on MCP/tool integrations. CodexClaw should make configured tools discoverable and healthy without requiring manual config spelunking.

Acceptance criteria

• Read and display detected MCP/tool configuration for the active Codex environment where available.
• Show enabled servers, command paths, arguments, environment requirements, and last health check status.
• Provide copyable setup snippets for common local servers such as filesystem, git, memory, and fetch.
• Never expose secret values in the UI or issue/export outputs.

Public research basis

• MCP servers repository points users to the MCP Registry and reference filesystem/git/memory/fetch servers.
• Open WebUI lists MCP and tool/plugin extensibility as part of a mature AI UI.
• Open SWE argues for curated tools rather than unbounded tool accumulation.

Non-goals

• No arbitrary secret entry in-browser.
• No automatic installation of third-party servers in the first pass.

Source set

• OpenAI Codex CLI - local terminal coding agent, installer paths, IDE/desktop context.
• OpenHands - local GUI with REST API + SPA, CLI, cloud collaboration/integrations.
• Aider - repo maps, git integration, image/web context, lint/test loops.
• Continue - source-controlled AI checks as markdown agents in CI.
• Open SWE - isolated sandboxes, AGENTS.md context, curated tools, subagents, Slack/Linear handoff.
• Model Context Protocol servers - tool/server registry pattern, filesystem/git/memory/fetch examples, security warnings.
• Open WebUI - responsive/PWA UI, RAG/web browsing, artifact storage, permissions.
• OpenCode - coding-agent modes, plan/build separation, subagent pattern.
• Cline - autonomous coding agent as SDK, IDE extension, and CLI assistant.
• Roo Code - agent-oriented coding workflow inside the editor.
