### MCP Server Management

## Key Functions

| Function | Purpose |
|----------|---------|
| `initializeMcpSystem()` | Start all MCP servers from config |
| `addMcpServer(id, config)` | Add new server dynamically |
| `removeMcpServer(id)` | Remove a server |
| `pauseMcpServer(id)` | Pause a server |
| `resumeMcpServer(id)` | Resume a paused server |
| `executeMcpAction(id, req)` | Call a tool on specific server |
| `getAllTools()` | List all available tools |
| `getClientsStatus()` | Get status of all MCP clients |
| `setConfigPath(path)` | Set custom config file location |
| `createPersistStore()` | Create Zustand store with persistence |
| `mergeSessions()` | Merge session arrays |
| `mergeWithUpdate()` | Merge with timestamp resolution |
| `mergeKeyValueStore()` | Merge key-value stores |

## Configuration

Create `mcp_config.json`:

import { 
  initializeMcpSystem, 
  addMcpServer, 
  executeMcpAction, 
  getAllTools 
} from "openclaw-claude-code-skill";

// 1. Initialize all configured servers
await initializeMcpSystem();

// 2. Add a new MCP server
await addMcpServer("fs", {
  command: "npx",
  args: ["-y", "@modelcontextprotocol/server-filesystem", "/tmp"]
});

// 3. Get available tools
const tools = await getAllTools();

// 4. Call a tool
const result = await executeMcpAction("fs", {
  method: "tools/call",
  params: { name: "read_file", arguments: { path: "/tmp/test.txt" } }
});

import { createPersistStore, indexedDBStorage } from "openclaw-claude-code-skill";

const useStore = createPersistStore(
  { count: 0, items: [] },
  (set, get) => ({
    increment: () => set({ count: get().count + 1 }),
    addItem: (item: string) => set({ items: [...get().items, item] })
  }),
  { name: "my-store" },
  indexedDBStorage  // or omit for localStorage
);

// Check hydration status
if (useStore.getState()._hasHydrated) {
  console.log("State restored!");
}

import { mergeSessions, mergeWithUpdate, mergeKeyValueStore } from "openclaw-claude-code-skill";

// Merge chat sessions from multiple sources
const mergedSessions = mergeSessions(localSessions, remoteSessions);

// Merge configs with timestamp-based resolution
const mergedConfig = mergeWithUpdate(localConfig, remoteConfig);
