# providers

# `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 theme={"theme":{"light":"snazzy-light","dark":"dark-plus"}}
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)])
```
