MCP Dev Summit Bengaluru 2026

Modern MCP applications depend on tools to extend model capabilities, yet tool interface design is a primary source of unreliability. Ambiguous descriptions, poorly structured schemas, and inconsistent outputs often lead to incorrect tool selection, invalid inputs, and unpredictable system behavior.

This session introduces a practical framework for designing reliable MCP tools. We begin with a concise mental model of how language models interpret tool interfaces, followed by real-world failure scenarios that expose common design pitfalls. Building on this, we present design principles for clear naming, well-defined schemas, and structured outputs, along with patterns for creating predictable and composable tools.

The session concludes with a practical checklist and actionable guidelines that attendees can immediately apply to improve reliability, reduce debugging complexity, and build robust MCP applications in production environments.
