## Build your tools

If the above tools don't meet your needs, you can build tools for your ADK
workflows using the following guides:

*   **[Function Tools](/adk-docs/tools/function-tools/)**: Build custom tools for
    your specific ADK agent needs.
*   **[MCP Tools](/adk-docs/tools/mcp-tools/)**: Connect MCP servers as tools
    for your ADK agents.
*   **[OpenAPI Integration](/adk-docs/tools-custom/openapi-tools/)**:
    Generate callable tools directly from an OpenAPI Specification.
