PROFILE
Will James
Will James contributed to dbt-labs/dbt-mcp by building and refining backend systems that enhance developer tooling and operational reliability. He introduced modular context classes to decouple discovery and semantic layer concerns, enabling richer API capabilities and easier onboarding for new features. Leveraging Python and asynchronous programming, Will integrated async HTTPX clients to improve responsiveness and reduce latency in data retrieval. He addressed memory leaks and improved shutdown reliability for long-running proxy sessions by pinning dependencies and implementing request-scoped task groups. His work demonstrated depth in API design, dependency management, and backend maintenance, ensuring stable, maintainable infrastructure for evolving data workflows.

Mar 1, 2026March 2026 monthly summary for dbt-labs/dbt-mcp: Focused on stabilizing long-running MCP proxy by mitigating memory leaks and ensuring graceful shutdown of SSE streams. Actions included pinning MCP SDK to a patched fork to fix stateless task leaks, introducing request-scoped task groups to prevent zombie tasks, and implementing a graceful SSE drain during shutdown. These changes reduce memory growth, prevent stale connections, and improve reliability of remote dbt operations. Prepared for upstream integration and revert to upstream once the fix is released. Technologies involved include Python, MCP Python SDK, dependency management, and SSE streaming.

Dec 1, 2025December 2025 monthly summary for dbt-mcp: Delivered Async HTTPX integration to make the semantic layer and discovery non-blocking, enabling faster retrieval of metrics, saved queries, dimensions, entities, and discovery results; fixed blocking requests in semantic layer gql paths and client, and standardized discovery prompts parameter names to 'name' to improve API clarity. These changes reduced latency, improved responsiveness, and streamlined onboarding for developers and users. Technologies demonstrated include asynchronous HTTP clients (httpx), GraphQL handling, and API design/maintenance across the semantic layer and discovery components.
