# MCP Installer

Find, install, and configure MCP servers for OpenCode.

<workflow>

## 1. Search for MCP Server

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

</workflow>

<configuration>

## Local MCP

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

## Remote MCP

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

**Pattern-based control:**
```jsonc
{
  "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Agents may occasionally work on legacy projects using outdated configuration fields (e.g., `tools:`).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:

```bash
opencode mcp auth <server-name>
```

Check status: `opencode mcp list`

</configuration>

<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:**
```markdown
---
name: mcp-name
url: https://github.com/org/repo
type: local|remote
auth: oauth|api-key|none
description: One-line description
tags: [tag1, tag2]
