An in-depth series on Model Context Protocol engineering, covering MCP server quickstarts, OAuth, remote servers, SSE transport, high-concurrency gateways, tool design, multi-agent constraint layers, AI-native app stores, and enterprise integration patterns.
Learn the Model Context Protocol from first principles: Host, Client, Server, JSON-RPC lifecycle, capability negotiation, Tools, Resources, Prompts, transports, and authorization boundaries. The guide separates protocol guarantees from application policy and shows how to choose an SDK, test a server, and avoid treating discovery or schema as security.
A production guide to MCP servers: choose stdio or Streamable HTTP, validate OAuth access tokens, bind sessions to principals, enforce tool authorization, paginate large results, and treat annotations and tool output as untrusted. Includes a Node.js security-oriented adapter design.
Compare Node.js and Go for an MCP server without treating a single benchmark as a universal ranking. This guide separates transport, JSON-RPC framing, tool execution, downstream I/O, memory, tail latency, deployment and team cost, then provides a reproducible workload protocol and a decision matrix for migration.
Implement the parts of a Go MCP transport that are easy to get wrong: protocol-profile selection, server-issued session state, JSON-RPC correlation, bounded event queues, cancellation, heartbeats, proxy buffering, authentication, and graceful shutdown. The guide treats legacy SSE as a compatibility path and does not present a partial transport as a complete production server.
A design guide for an MCP gateway that must manage remote sessions, routing, backpressure, authorization, and failure recovery. It distinguishes current and legacy transports, explains when connection pooling or session affinity is valid, and covers bounded Go-shaped examples, distributed state, observability, and workload-specific load testing.
Build and verify a small local MCP Server with Node.js, TypeScript, the official MCP SDK, Zod, and stdio. This tutorial focuses on one bounded read-only Tool, shows the build and Inspector loop, explains stdout logging and client configuration, and marks the security and transport work required before a remote or state-changing deployment.
Master the craft of writing tools that LLMs can use reliably. This guide covers the anatomy of a great tool definition, 10 practical best practices for MCP tools and function-calling schemas, anti-patterns to avoid, testing strategies, and composition patterns — with before/after code examples.
A version-aware guide to MCP specification changes around remote HTTP, authorization, sessions, tool annotations, and capability discovery. It separates normative protocol requirements from OAuth profiles, SDK behavior, registries, and host conventions, then provides a migration checklist and tests for upgrading a server without turning hints or discovery metadata into security controls.
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.
A production guide to composing MCP tool boundaries, A2A-style remote task delegation, and A2UI-style user interface contracts. Learn which boundary each approach serves, when a local workflow is safer, how to enforce identity and object authorization, and how to test artifacts, actions, cancellation, retries, privacy, and rollback.
A production guide to using MCP-style tool boundaries in multi-Agent systems without confusing schemas or protocol metadata for authorization. Learn how to combine trusted identity, object-level policy, limits, approval, concurrency control, audit, untrusted tool-result handling, and failure recovery around a pinned protocol implementation.
Design an enterprise OAuth boundary for a remote MCP server without confusing authentication with authorization. This guide covers protected-resource metadata, discovery, PKCE, JWT validation, JWKS rotation, delegated downstream access, tenant isolation, browser boundaries, and production testing.
A practical guide to evaluating MCP-based products without confusing a protocol with an app store. Learn how Hosts, Clients, Servers, Tools, Resources, identity, billing, approvals, and distribution fit together, when a capability should become a product, and which reliability, privacy, and supply-chain controls must be in place before publication.
