name: mcp-installer description: Find, install, and configure Model Context Protocol (MCP) servers for OpenCode. Use when user asks about finding MCP servers, installing them, configuring OAuth, or troubleshooting MCP issues.

MCP Installer

Find, install, and configure MCP servers for OpenCode.

1. Search for MCP Server

Check local catalog first (quick check for already-documented MCPs):

python3 ~/.config/opencode/skill/mcp-installer/scripts/list_mcps.py

If not found locally, search online:

• websearch("MCP server for [capability]")
• webfetch("https://github.com/modelcontextprotocol/servers")
• Check npm: @modelcontextprotocol/server-*
• Check the MCP spec repo: https://github.com/modelcontextprotocol

2. Read MCP Details

For relevant matches, read the full MCP file:

references/mcps/<name>.md

Contains installation config, setup, features, and links.

3. Configure

Add the MCP config to user's opencode.json.

4. Document New MCPs

If you discovered a new MCP server online, you MUST document it for future reference in references/mcps/<name>.md using the template below.

5. Setup (if needed)

• OAuth: Run opencode mcp auth <server-name>
• API keys: Set environment variables
• Other: Follow MCP-specific setup steps

Local MCP

{
  "mcp": {
    "name": {
      "type": "local",
      "command": ["npx", "-y", "@package/name"]
    }
  }
}

Remote MCP

{
  "mcp": {
    "name": {
      "type": "remote",
      "url": "https://example.com/mcp"
    }
  }
}

MCP Tool Management

MCPs expose tools. Control via the permission section using the tool name (usually the MCP name):

Global/Agent Permission:

{
  "permission": {
    "my-mcp": "deny",          // Disable all tools for this MCP
    "my-mcp*": "deny"          // Wildcard support
  }
}

Pattern-based control:

{
  "permission": {
    "my-mcp": {
      "safe_tool": "allow",
      "risky_tool": "ask",
      "*": "deny"
    }
  }
}

Legacy Configuration

Agents may occasionally work on legacy projects using outdated configuration fields (e.g., tools:). You MUST correct these to the modern permission: system when encountered.

OAuth

Remote MCPs with OAuth auto-authenticate:

opencode mcp auth <server-name>

Check status: opencode mcp list

<reference_files>

You need...	Read this file
All config options (local, remote, oauth, env vars)	references/configuration.md
Common MCP server examples	references/examples.md
Troubleshooting issues	references/troubleshooting.md

Note: The local catalog (list_mcps.py) is a cache of discovered MCPs, not a complete list. SHOULD always search online if you don't find a match locally.

</reference_files>

<documenting_new_mcps>

When discovering new MCP servers, you MUST document them:

Location: references/mcps/<name>.md

Template:
