MCP Setup for n8n Development in OpenCode

Configure commonly used MCP servers for n8n engineers using OpenCode MCP config.

Instructions

1. Check which MCPs are already configured by running, if available:

opencode mcp list

Parse by URL or command, not just server name. Skip any MCP whose URL is already present.

Known MCP URLs:

• Linear: https://mcp.linear.app/mcp
• Notion: https://mcp.notion.com/mcp
• Context7: https://mcp.context7.com/mcp
• Figma: https://mcp.figma.com/mcp

2. Ask the user which unconfigured MCPs they want to add. If all are already configured, tell the user and stop.

Option	Label	Description
Linear	Linear	Linear ticket management with OAuth
Notion	Notion	Notion workspace integration with OAuth
Context7	Context7	Library documentation lookup
Figma	Figma	Figma design integration with OAuth

3. Ask once whether to install in user or project scope.

Scope	Config path	When to use
user	~/.config/opencode/opencode.json	Default. Available in all projects.
project	./opencode.json	Only when the user explicitly wants repo-local config.

4. Add the selected MCP entries under the mcp object in the selected config. Preserve existing config keys and existing MCP entries.

{
  "mcp": {
    "linear": {
      "type": "remote",
      "url": "https://mcp.linear.app/mcp",
      "enabled": true
    },
    "notion": {
      "type": "remote",
      "url": "https://mcp.notion.com/mcp",
      "enabled": true
    },
    "context7": {
      "type": "remote",
      "url": "https://mcp.context7.com/mcp",
      "enabled": true
    },
    "figma": {
      "type": "remote",
      "url": "https://mcp.figma.com/mcp",
      "enabled": true
    }
  }
}

5. After editing config, tell the user to authenticate OAuth-backed servers with:

opencode mcp auth <server-name>

Use the configured server names, for example linear, notion, or figma. Context7 does not require OAuth by default.
