FAQPage Schema

How do I build a custom MCP server for Claude Code?▼

Building a custom MCP server for Claude Code involves defining Python-based tools with FastMCP, configuring the Model Context Protocol, and registering the server locally so Claude Code can discover and invoke your custom tools during sessions.

What is the Model Context Protocol and when do I need it?▼

The Model Context Protocol (MCP) is a standard for extending AI assistants with custom tools and integrations. You need MCP when built-in Claude Code capabilities are insufficient and you want to connect external APIs, files, databases, or internal services to your workflow.

Can I use FastMCP to create remote MCP servers with HTTP transport?▼

Yes, FastMCP supports remote MCP server development using Streamable HTTP transport. This allows you to deploy servers beyond local environments and enables advanced patterns like elicitation workflows for broader API and service integration with Claude Code.

How do I register an MCP server and verify tool availability in Claude Code?▼

To register an MCP server in Claude Code, you configure the server connection settings and then verify tool availability directly within a Claude Code session. This Skill covers the registration process and validation checks required to ensure your custom tools are accessible.

Do I need Python to develop MCP servers for Claude Code?▼

Python is the primary development language covered for building MCP servers with Claude Code. This Skill focuses on Python MCP development scenarios using FastMCP, requiring typed tool definitions and structured responses for server integration.

What are the limitations of using MCP servers with Claude Code?▼

MCP servers with Claude Code require proper protocol configuration, FastMCP-based tool definitions, and validation checks to function correctly. Limitations include the need for local server registration or remote transport setup, and ensuring structured responses match expected formats for workflow automation.
