Canonical reference for the unified `Context` object passed to every tool and resource handler in `@cyanheads/mcp-ts-core`. Covers the full interface, all sub-APIs (`ctx.log`, `ctx.state`, `ctx.elicit`, `ctx.sample`, `ctx.progress`), and when to use each.

McpError constructor, JsonRpcErrorCode reference, and error handling patterns for `@cyanheads/mcp-ts-core`. Use when looking up error codes, understanding where errors should be thrown vs. caught, or using ErrorHandler.tryCatch in services.

MCP definition linter rules reference. Use when `bun run lint:mcp`, `bun run devcheck`, or `createApp()` startup reports a lint error or warning (`format-parity`, `schema-is-object`, `name-format`, `server-json-*`, etc.) and you need to understand the rule, its severity, and how to fix it. Every rule ID the linter emits has an entry in this doc.

API reference for built-in service providers (LLM, Speech, Graph). Use when looking up service interfaces, provider capabilities, or integration patterns.

Catalog of OpenTelemetry instrumentation built into framework `@cyanheads/mcp-ts-core` — spans, metrics, completion logs, env config, runtime caveats, custom instrumentation patterns, and cardinality rules. Use when enabling OTel export, adding custom spans or metrics in services, debugging missing telemetry, looking up attribute names, or deciding what's safe to put on a metric attribute vs. a span.
