MCP Servers: From Developer Skills to Security and Multi-Tenancy Challenges
ByPulseAugur Editorial·[25 sources]·
A collection of articles discusses the Model Context Protocol (MCP) and its implementation in various AI agent systems. One developer shares their experience publishing eight installable "Agent Skills" and an MCP server to npm, categorizing them for external APIs, homelab workflows, and general utilities. Other articles delve into the security implications of remote MCP servers, highlighting common mistakes like unauthenticated tool calls and improper OAuth 2.1 implementation. The challenges of multi-tenancy in MCP are addressed, with a proposed solution using a gateway like Bifrost to isolate tools and manage credentials. Additionally, the inefficiency of using verbose JSON schemas for LLM context is discussed, with a proposed solution using compact schema representations to reduce token usage and improve latency.

<p>From Zero to Shipped: My Journey Building an MCP Server</p> <p>Six weeks ago, "MCP" didn't mean anything to me. Today, I've shipped tools, published a live website, and learned more about backend engineering — and about myself as a builder — than I expected from a single cohor…
<p>The first time I configured my coding agent to use an MCP server, the <code>"command": "npx"</code> part got me a bit weirded out. Is this going to run as a child process? Isn’t it an MCP “server” though!? So, I started exploring this fairly new world of MCP.</p> <p>If you are…
<p>AI agents are increasingly good at reasoning, but they still need a reliable way to find and use real-world tools. The usual approach—adding one integration at a time—quickly becomes difficult to maintain. Every server adds schemas, authentication, error handling, and more con…

<p>Remote MCP servers are shipping fast, and a lot of them are generated straight out of an OpenAPI spec or a no-code builder. That is fine for a demo. It stops being fine the moment a real agent, holding real credentials, is allowed to call real tools against real customer data.…
