How to use Claude tool in MCP

What is MCP in Claude?

MCP = Model Context Protocol

It helps Anthropic’s Claude connect with:

• GitHub
• Slack
• Databases
• Local files
• Browsers
• APIs
• DevOps tools
• External applications

Think of MCP like:

“USB-C for AI tools”

Claude can directly use connected tools instead of only chatting.

How Claude + MCP Works:

Architecture:

Claude (Host)

Example:

• Claude → GitHub MCP → Create PR
• Claude → Browser MCP → Open website

claude mcp add filesystem -- npx -y @modelcontextprotocol/server-filesystem ~/Desktop

Now Claude can:

• Read files
• Create files
• Modify files

Example 2 — GitHub MCP

claude mcp add github \
  --env GITHUB_TOKEN=your_token \
  -- npx -y @modelcontextprotocol/server-github

Claude can now:

• Create PRs

• Check issues
• Commit code

Step 4: Verify MCP Servers
