# Add an MCP Server

Add an MCP server configuration to `pi-mcp-adapter`. Determine scope and server type, write the config, and verify the connection.

## Step 1: Determine Scope

Ask the user if not obvious from context:

| Scope | Config File | When to Use |
|-------|-------------|-------------|
| **Global** | `~/.pi/agent/mcp.json` | Server used across all projects |
| **Project** | `.pi/mcp.json` (project root) | Server specific to one project |

Project-local configs override global ones. Both files use the same format.

## Step 2: Determine Server Type

MCP servers connect via **stdio** (local process) or **HTTP** (remote URL).

**Stdio server** — runs a local command:
```json
{
  "mcpServers": {
    "server-name": {
      "command": "npx",
      "args": ["-y", "package-name@latest"],
      "env": { "KEY": "value" }
    }
  }
}
```

**HTTP server** — connects to a URL:
```json
{
  "mcpServers": {
    "server-name": {
      "url": "http://localhost:8080/mcp",
      "headers": { "Authorization": "Bearer token" }
    }
  }
}
```

## Step 3: Gather Configuration

Collect only what's needed. All fields except `command`/`url` are optional.

| Field | Type | Description |
|-------|------|-------------|
| `command` | string | Executable to run (stdio) |
| `args` | string[] | Command arguments (stdio) |
| `env` | object | Environment variables (stdio) |
| `cwd` | string | Working directory (stdio) |
| `url` | string | Server URL (HTTP) |
| `headers` | object | HTTP headers (HTTP) |
| `auth` | `"oauth"` or `"bearer"` | Auth method (HTTP) |
| `bearerToken` | string | Static bearer token |
| `bearerTokenEnv` | string | Env var name for bearer token |
| `lifecycle` | `"lazy"` / `"eager"` / `"keep-alive"` | Connection strategy (default: `lazy`) |
| `idleTimeout` | number | Minutes before idle disconnect |
| `debug` | boolean | Show server stderr |

Lifecycle modes:
- **lazy** (default) — connects on first tool call, disconnects after idle timeout
- **eager** — connects at session start, no auto-disconnect
- **keep-alive** — connects at start, auto-reconnects if dropped

## Step 4: Write the Config

1. Read the target config file if it exists
2. Merge the new server into the existing `mcpServers` object
3. Write the updated JSON

If the file doesn't exist, create it with the full structure:
```json
{
  "mcpServers": {
    "server-name": { ... }
  }
}
```

Warn if a server with the same name already exists and confirm before overwriting.

## Step 5: Verify

1. Run `/reload` to pick up the new config
2. Use `mcp({ connect: "server-name" })` to test the connection
3. Use `mcp({ server: "server-name" })` to list available tools
4. Report success or troubleshoot connection errors
