SDK MCP Server

A configurable Model Context Protocol (MCP) server that provides searchable access to multiple AI/ML SDK documentation and source code. Currently supports OpenAI Agents SDK and Google ADK, with easy extensibility for additional SDKs.

When working with AI/ML SDKs, you often need to:

- Understand how classes and methods work internally across different SDKs
- Compare implementations between different frameworks
- Find the right method signatures and parameters
- See real implementation examples
- Debug issues by examining SDK source code

This MCP server gives AI assistants like Claude instant access to multiple SDK sources, making it a powerful development companion for multi-SDK projects.

This will download all configured SDKs fromsdks.yaml.

Add to your Claude Desktop configuration:

{ "mcpServers": { "sdk-mcp-server": { "command": "python", "args": ["/absolute/path/to/sdk-mcp-server/src/server.py"] } } }

Each configured SDK gets its own set of tools with the SDK prefix. Currently configured:

OpenAI Agents SDK Tools (prefix:openai_agents_)

- openai_agents_list_files()- List all available OpenAI SDK source files
- openai_agents_get_source(filename)- Get source code of specific file
- openai_agents_search_code(query)- Search for terms, methods, or patterns
- openai_agents_get_class(class_name)- Extract complete class definition
- openai_agents_find_examples(topic)- Find usage examples and patterns

- google_adk_list_files()- List all available Google ADK source files
- google_adk_get_source(filename)- Get source code of specific file
- google_adk_search_code(query)- Search for terms, methods, or patterns
- google_adk_get_class(class_name)- Extract complete class definition
- google_adk_find_examples(topic)- Find usage examples and patterns

- list_available_sdks()- Show all configured SDKs
- search_all_sdks(query)- Search across all SDKs simultaneously
- compare_implementations(concept, sdk_ids)- Compare similar concepts across SDKs

You: "How do OpenAI and Google handle agent creation differently?" Claude: [Uses openai_agents_get_class("Agent") and google_adk_get_class("Agent")] Compares the different approaches and APIs

You: "Show me how to use tools in Google ADK" Claude: [Uses google_adk_search_code("tool") and google_adk_find_examples("tool")] Explains Google's approach with real examples

You: "Why does handoff work in OpenAI but not in my Google ADK code?" Claude: [Searches both SDKs for handoff implementations] Identifies the differences and helps fix the issue
