Do I need to run my own MCP server?

Not necessarily. Many MCP skills connect to hosted servers maintained by the skill publisher. For custom integrations with internal systems, you may need to run your own MCP server, but hosted options cover most common use cases.

Is MCP an OpenClaw-specific protocol?

No. MCP is an open standard used across the AI ecosystem. This means MCP servers built for other AI tools often work with OpenClaw, and vice versa. The broad adoption means a rich ecosystem of available servers.

What happens if the MCP server goes offline?

If the MCP server is unreachable, the agent reports that the tools are unavailable and falls back to other capabilities. It does not fail silently. You can configure alerts for MCP connection failures so you know when tools are offline.

MCP (Model Context Protocol) Skills

Connect your OpenClaw agent to external tools, databases, and services through MCP. Expand your agent's capabilities by adding MCP server integrations.

What You Will Get

After this guide, you will understand how the Model Context Protocol (MCP) works with OpenClaw and how to use MCP-based skills to connect your agent to external tools and services. MCP is a standardized protocol that lets AI agents interact with external systems through a consistent interface.

Think of MCP as a universal adapter. Instead of building custom integrations for every tool, MCP provides a standard way for your agent to discover available tools, understand their capabilities, and call them. When you install an MCP skill, your agent gains access to all the tools that MCP server provides.

MCP skills cover a wide range: database access, file system operations, API calls, browser automation, and more. Each MCP server exposes a set of tools with clear schemas, so your agent knows exactly what parameters each tool expects and what it returns.

How to Use MCP Skills

Connect and use MCP server integrations

Understand MCP Architecture

MCP works on a client-server model. Your OpenClaw agent is the client. MCP servers provide tools and resources. When you install an MCP skill, your agent connects to the MCP server and discovers its available tools. Each tool has a name, description, and input schema that the agent uses to invoke it correctly.

Find MCP Skills on ClawHub

Search ClawHub for MCP skills using keywords like MCP, Model Context Protocol, or the specific service you want to connect. MCP skills are tagged with the mcp category. Each listing shows which tools the MCP server provides and what external services it connects to.

Install the MCP Skill

Install the MCP skill from ClawHub like any other skill. The installation process sets up the MCP server connection and registers the available tools with your agent. Some MCP skills require additional configuration, such as database connection strings or API endpoints, which you configure after installation.

Configure the MCP Server Connection

Open the skill's configuration and set up the MCP server connection. This typically includes the server address, authentication credentials, and any environment-specific settings. For local MCP servers (running on the same infrastructure), configuration is minimal. For remote servers, you need the connection URL and authentication token.

Discover Available Tools

After connecting, ask your agent: what tools are available from the [mcp-skill-name] server. The agent lists all available tools with their descriptions and parameter schemas. This helps you understand what capabilities the MCP skill provides and how to invoke each tool through natural language.

Use MCP Tools Through Chat

Invoke MCP tools naturally through chat. For example, if you installed a database MCP skill, you can say: query the users table for all active accounts created in the last month. The agent translates your request into the appropriate MCP tool call, executes it, and returns the results in a readable format.

Monitor MCP Tool Usage

Track how your agent uses MCP tools to ensure they work correctly and efficiently. Check the agent logs for MCP tool calls, their execution times, and any errors. This monitoring helps you identify slow tools, failing connections, or unexpected behavior that needs attention.

Tips and Best Practices

Start with Official MCP Servers

Begin with well-maintained official MCP servers for common services. These have the best documentation, reliability, and community support. Expand to community-maintained servers once you are comfortable with the MCP workflow.

Secure Your MCP Connections

MCP servers may access sensitive systems like databases and APIs. Ensure connections use encrypted transport, credentials are stored securely, and access is scoped to only the operations your agent needs. Follow the principle of least privilege.

Combine MCP Skills with Regular Skills

MCP skills work alongside regular skills. Use regular skills for workflow logic and MCP skills for tool access. For example, a regular skill might define the code review workflow while an MCP skill provides access to the Git repository and code analysis tools.

Regular Skills vs. MCP Skills

Regular Skills

Define workflows and instructions
Activated by user intent or triggers
Self-contained logic in SKILL.md
No external server dependency
Best for process and knowledge skills

MCP Skills

Provide tool access via protocol
Discovered automatically on connection
Backed by an external MCP server
Requires server to be running
Best for tool integration and data access
