+
+
+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)])
+    ```
