MCP Protocol Mastery

Understand MCP 2026-07-28: stateless requests, server discovery, Tools, Resources, Prompts, Streamable HTTP, OAuth, MRTR, caching, and security controls.

Build MCP 2026-07-28 servers with stateless HTTP, explicit state handles, OAuth authorization, bounded results, safe retries, and auditable operations.

Compare Node.js and Go MCP servers with a reproducible benchmark aligned to MCP 2026-07-28. Separate protocol, transport, authorization, tool, dependency, and observability cost; define equivalent SDK profiles; measure tail latency, saturation, recovery, and cost per successful task; and decide whether to tune, isolate, or migrate.

Build a Go MCP remote transport for protocol 2026-07-28 using one POST endpoint, stateless per-request metadata, JSON or request-scoped SSE responses, cancellation, explicit subscriptions, OAuth boundaries, proxy controls, graceful shutdown, and the official Go SDK. Also explains why legacy GET /sse plus POST /message designs must remain isolated compatibility paths.

Design a production MCP Gateway for MCP 2026-07-28 stateless core. Learn header routing, OAuth boundaries, backpressure, safe retries, caching, and load tests.

Build an MCP 2026-07-28 server with Node.js, TypeScript SDK v2, Zod, stdio, structured results, and reproducible Inspector tests with clear boundaries.

Design production MCP tools for the 2026-07-28 protocol: precise selection descriptions, strict input and output schemas, structured content, result types, multi-round input, explicit state handles, least-privilege authorization, idempotency, bounded results, and layered evaluation, with a runnable Go SDK example.

Migrate MCP clients and servers from the 2025 revisions to MCP 2026-07-28. This version-aware guide covers stateless requests, server/discover, Streamable HTTP without protocol sessions, MRTR, resultType, OAuth protected-resource discovery, Client ID Metadata Documents, Skills and Tasks extensions, compatibility tests, and rollback.

A version-aware guide to MCP registries and catalogs. Learn what a registry can prove about a server, how package and remote metadata should be reviewed, how enterprises can curate a private index, and how to design approval, provenance, credential, rollback, and deletion controls before an MCP capability reaches an Agent.

Compose MCP 2026-07-28, A2A 1.0, and A2UI safely. Learn tool, remote-task, and rendered-UI boundaries, version negotiation, authorization, recovery, and interoperability testing without treating three independent protocols as one mandatory stack.

Design secure multi-agent systems around MCP 2026-07-28 without mistaking protocol metadata for policy. This production guide covers stateless requests, OAuth audience validation, delegated identity, object authorization, approval binding, explicit state handles, idempotency, untrusted results, concurrency, audit, and failure recovery.

Implement remote MCP OAuth against the 2026-07-28 specification. This engineering guide covers protected-resource discovery, CIMD, issuer binding, resource indicators, PKCE, step-up scopes, token validation, tenant authorization, SSRF, and token-passthrough defenses.

Build MCP Apps against the stable 2026-01-26 UI extension. Understand ui:// resources, tool metadata, capability negotiation, structuredContent, app-only tools, iframe sandboxing, CSP, server authorization, progressive fallback, compatibility tests, and release evidence without confusing interactive UI with an app store.
