--- title: Reading Resources sidebarTitle: Resources description: Access static and templated data sources from MCP servers. icon: folder-open --- import { VersionBadge } from '/snippets/version-badge.mdx' Use this when you need to read data from server-exposed resources like configuration files, generated content, or external data sources. Resources are data sources exposed by MCP servers. They can be static files with fixed content, or dynamic templates that generate content based on parameters in the URI. ## Reading Resources Read a resource using its URI: ```python async with client: content = await client.read_resource("file:///path/to/README.md") # content -> list[TextResourceContents | BlobResourceContents] # Access text content if hasattr(content[0], 'text'): print(content[0].text) # Access binary content if hasattr(content[0], 'blob'): print(f"Binary data: {len(content[0].blob)} bytes") ``` Resource templates generate content based on URI parameters. The template defines a pattern like `weather://{{city}}/current`, and you fill in the parameters when reading: ```python async with client: # Read from a resource template weather_content = await client.read_resource("weather://london/current") print(weather_content[0].text) ``` ## Content Types Resources return different content types depending on what they expose. Text resources include configuration files, JSON data, and other human-readable content: ```python async with client: content = await client.read_resource("resource://config/settings.json") for item in content: if hasattr(item, 'text'): print(f"Text content: {item.text}") print(f"MIME type: {item.mimeType}") ``` Binary resources include images, PDFs, and other non-text data: ```python async with client: content = await client.read_resource("resource://images/logo.png") for item in content: if hasattr(item, 'blob'): print(f"Binary content: {len(item.blob)} bytes") print(f"MIME type: {item.mimeType}") # Save to file with open("downloaded_logo.png", "wb") as f: f.write(item.blob) ``` ## Multi-Server Clients When using multi-server clients, resource URIs are prefixed with the server name: ```python async with client: # Multi-server client weather_icons = await client.read_resource("weather://weather/icons/sunny") templates = await client.read_resource("resource://assistant/templates/list") ``` ## Version Selection When a server exposes multiple versions of a resource, you can request a specific version: ```python async with client: # Read the highest version (default) content = await client.read_resource("data://config") # Read a specific version content_v1 = await client.read_resource("data://config", version="1.0") ``` See [Metadata](/servers/versioning#version-discovery) for how to discover available versions. ## Raw Protocol Access For complete control, use `read_resource_mcp()` which returns the full MCP protocol object: ```python async with client: result = await client.read_resource_mcp("resource://example") # result -> mcp.types.ReadResourceResult ```
