name	dev-mcp-setup
description	Configure MCP servers for the workspace — web search, filesystem, GitHub, Stripe, etc. Use when adding a new integration that needs MCP-level access.

Dev MCP Setup

Derived from oh-my-claudecode (MIT, Yeachan Heo). Adapted for the EvoNexus Engineering Layer.

Configure MCP (Model Context Protocol) servers for the workspace. When a new integration needs access at the MCP layer (rather than via skill-level API calls), this skill walks through the configuration.

Use When

• Adding a new MCP-backed integration (web search, GitHub, Notion, etc.)
• Diagnosing why an existing MCP server isn't responding
• Setting up a fresh EvoNexus workspace with all standard MCPs

Do Not Use When

• The integration is API-based (use the appropriate int-* skill instead)
• You just need to invoke an existing MCP tool (just use it)

EvoNexus Standard MCPs

These are typically configured in ~/.claude/settings.json or .claude/settings.json:

MCP	Purpose	Setup
google-calendar	Calendar events	OAuth
gmail	Email read/send	OAuth
linear-server	Linear issues/projects	API key
github	GitHub PRs/issues/files	GitHub token
canva	Design files	OAuth
claude_ai_Notion	Notion pages	OAuth
computer-use	Desktop control	local
figma	Design files	OAuth
plugin_telegram	Telegram bot	bot token

Workflow

1. Identify which MCP server you need to add
2. Check current config — read .claude/settings.json (project) or ~/.claude/settings.json (user)
3. Add the server entry with its required env vars or auth
4. Restart Claude Code to load the new MCP
5. Verify by listing tools — the new MCP's tools should appear with mcp__<server>__* prefix
6. Document the addition in workspace/development/research/[C]mcp-setup-{server}-{date}.md

Configuration Example

{
  "mcpServers": {
    "github": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-github"],
      "env": {
        "GITHUB_TOKEN": "${GITHUB_TOKEN}"
      }
    }
  }
}

Diagnostics

If an MCP isn't working:

1. Check Claude Code logs for spawn errors
2. Verify env vars are set
3. Test the MCP server independently if possible
4. Check that the MCP package is installed

Pairs With

• update-config (built-in skill for settings.json edits)
• @scout-explorer (to find existing MCP configurations)
