+### Filtering by Tags
+
+You can use the `meta` field to filter prompts based on their tags:
+
+```python
+async with client:
+    prompts = await client.list_prompts()
+    
+    # Filter prompts by tag
+    analysis_prompts = [
+        prompt for prompt in prompts

+           'analysis' in prompt._meta.get('tags', [])
+    ]
+    
+    print(f"Found {len(analysis_prompts)} analysis prompts")
+```
+
+<Note>
+The `_meta` field is part of the standard MCP specification, but the inclusion of tags within it is specific to FastMCP servers. Other MCP server implementations may not provide tags in their metadata.
