7 articles
A 2026 review of the 25 Model Context Protocol (MCP) servers most worth integrating, covering GitHub, databases, browsers, filesystem, code search, Google Workspace, Slack, Notion, and more. Includes official SDK vs community implementations and configuration in Claude Code, Cursor, and Cline.
Systematic guide to MCP Server authentication in enterprise deployment, from MCP protocol built-in OAuth2 flow to self-built JWT + Scope RBAC system. Covers three-level permission granularity (tool-level, resource-level, operation-level), and integration with three enterprise identity services: Keycloak, Auth0, and Ory Hydra.
MCP security design lags significantly behind feature development. A systematic deep dive into four threat models, OAuth 2.1 authorization, fine-grained scope design, path access control, sensitive data redaction, call auditing, MCP Gateway deployment, and tool supply chain security.
Are MCP tool calls 10-100x slower than direct HTTP? A systematic deep dive into MCP Server performance bottleneck analysis, protocol-layer optimization (payload size, on-demand tool registration, streaming responses), transport-layer optimization (stdio long connection, HTTP/2, connection pool), tool-internal optimization (async, caching, pre-warming), and deployment-layer optimization.
A systematic deep dive into Playwright MCP Server: three deployment patterns (local, remote, cloud), the browser_snapshot accessibility tree mechanism, tool-calling patterns, security boundaries (URL allowlist, operation auditing, data exfiltration detection), and typical application scenarios.
Build a production-grade MCP server from scratch, covering tool definition, authentication design, and testing strategies to turn any API into an agent-ready tool.
From protocol modeling and server design to permission isolation, this guide shows how to build a stable tool integration layer for AI agents with MCP.
