OpenClaw + MCP: How to Connect Your Agent to 1,000+ Tools

What Is Model Context Protocol?

Model Context Protocol (MCP) is an open standard developed by Anthropic that defines how AI models and agents connect to external tools, data sources, and services. Think of it as a universal adapter — instead of each AI tool needing custom integrations for every service, MCP provides a standard interface that any AI agent can use to connect to any MCP-compatible tool.

The analogy to USB is apt: before USB, every peripheral had its own connector. USB standardised the interface, making it trivially easy to connect any device to any computer. MCP does the same for AI tool integrations.

MCP and OpenClaw

OpenClaw's native MCP support (added in early 2026) allows your agent to connect to any MCP server — a service that exposes its functionality through the MCP protocol. The ecosystem of MCP servers has grown rapidly, with major platforms including Notion, GitHub, Slack, Google Drive, Salesforce, HubSpot, and hundreds of others now offering MCP-compatible interfaces.

For OpenClaw users, MCP dramatically expands the range of tools your agent can use without requiring custom integration code. If a tool has an MCP server, your agent can use it.

The Composio Bridge: 1,000+ Tools via MCP

Composio, the OAuth middleware service that SetupClaw uses for credential management, also provides an MCP bridge that connects OpenClaw to over 1,000 tools. This includes popular tools like Notion, Airtable, Trello, Asana, Jira, Salesforce, HubSpot, Xero, QuickBooks, Stripe, and many more.

The Composio MCP bridge handles authentication for all connected tools — your agent makes requests through Composio, which manages the OAuth tokens and API credentials. This means you get both the breadth of 1,000+ integrations and the security of centralised credential management.

High-Value MCP Integrations for Asia Businesses

The most valuable MCP integrations vary by business type, but some consistently high-value connections for Asia-based businesses include: Notion (for knowledge management and documentation), Xero or QuickBooks (for financial data), HubSpot or Salesforce (for CRM), Google Drive (for document access), GitHub (for technical teams), and Airtable (for structured data management).

For Hong Kong and Singapore businesses with specific local needs, there are MCP servers for local banking APIs (HSBC, Standard Chartered, DBS), Hong Kong government data sources, and Singapore's MyInfo platform.

Context Window Considerations

One important caveat about MCP: connecting many MCP servers to your agent consumes context window space. Each connected MCP server adds its tool definitions to the agent's context, and with many servers connected, you can consume a significant portion of the available context before the agent has processed any actual content.

The practical guidance is to connect only the MCP servers your agent actually needs for its specific workflows. A CEO agent doesn't need access to GitHub. A Sales agent doesn't need access to financial accounting tools. Keeping tool access minimal improves both performance and security.

Building Custom MCP Servers

For businesses with proprietary systems or internal tools, building a custom MCP server is a practical option. The MCP specification is open and well-documented, and there are SDKs for Python, TypeScript, and other languages. A custom MCP server can expose your internal CRM, your proprietary database, or any other system as a tool your OpenClaw agent can use.

This is particularly relevant for larger Asia businesses with legacy systems — a custom MCP server can bridge your agent to systems that don't have native MCP support, without requiring changes to those systems.
