# `fastmcp.server.providers`


Providers for dynamic MCP components.

This module provides the `Provider` abstraction for providing tools,
resources, and prompts dynamically at runtime.

Example:
    ```python
    from fastmcp import FastMCP
    from fastmcp.server.providers import Provider
    from fastmcp.tools import Tool

    class DatabaseProvider(Provider):
        def __init__(self, db_url: str):
            self.db = Database(db_url)

        async def list_tools(self) -> list[Tool]:
            rows = await self.db.fetch("SELECT * FROM tools")
            return [self._make_tool(row) for row in rows]

        async def get_tool(self, name: str) -> Tool | None:
            row = await self.db.fetchone("SELECT * FROM tools WHERE name = ?", name)
            return self._make_tool(row) if row else None

    mcp = FastMCP("Server", providers=[DatabaseProvider(db_url)])
    ```
