Feature: MCP Server — Tools, Resources, Prompts

examples/adapters-mcp¶

Demonstrates all three MCP primitives:

• Tools — CalcTool with codec-driven inputSchema; input validation errors surface to the LLM as IsError: true results; output codec failures are protocol-level errors
• Resources — ItemResource with URI template items://{id}; BuildURI validates the id parameter before assembling the URI
• Prompts — SummaryPrompt with required content arg and optional style; ValidateArgs returns MissingPromptArgError for absent required args
• b.MCPSpec() — static JSON manifest listing all primitives with their codec-derived JSON Schemas
• All three transport options: stdio, streamable HTTP (recommended), SSE over HTTP (legacy)
