The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Make Your REST API Callable by Claude: A Practical MCP Primer
If you'd rather hand-roll it, the Python SDK and TypeScript SDK are both solid and the protocol itself is small enough to read in an afternoon.

The Seven Deadly Sins of MCP: Road to Redemption
These are the tests that catch the kinds of misleading errors, state leakage, and contract drift seen in modelcontextprotocol/typescript-sdk #699, modelcontextprotocol/python-sdk #756, and modelcontextprotocol/typescript-sdk #451 before users do. A server with only happy-path coverage is usually one incident away from rediscovering Sloth, Wrath, or Pride the hard way.

The Seven Deadly Sins of MCP: Operational Sins
This pattern shows up in modelcontextprotocol/typescript-sdk #699, where a real tool exception was replaced by a misleading -32602 structured-content error. Once a system starts lying about why it failed, every downstream debugging step gets more expensive. A vague error is not a small quality issue. It is operational debt with interest.

The Seven Deadly Sins of MCP: Design Sins
This is the engineering lesson behind modelcontextprotocol/typescript-sdk #451, where subclassing McpServer broke tool argument passing, and modelcontextprotocol/typescript-sdk #745, where generated JSON Schema drifted from what newer clients expected.

Universal MCP Server: Two Tools, 56 APIs
Universal CodeMode runs on Cloudflare Workers with R2 for spec storage and KV for caching. The core is TypeScript, using Hono for routing and the MCP TypeScript SDK for the protocol layer.

How we stopped giving our AI agents raw API keys
OpenSeed runs multiple creatures concurrently. The orchestrator spawns Janee once as a child process in HTTP mode. Each creature gets its own MCP session. Janee creates a fresh Server and Transport instance per initialize handshake, following the official MCP SDK pattern.

Tutorial: How to Serve REST and MCP on the Same Server
Using @ttoss/http-server and @ttoss/http-server-mcp, which are built on top of Koa and the official Model Context Protocol TypeScript SDK, this example showcases how to integrate traditional REST APIs with AI-compatible MCP endpoints in a single application.

The Seven Deadly Sins of MCP: Road to Redemption
a tool catalog grows without pagination, filtering, or explicit enablement, as in modelcontextprotocol/java-sdk #615
-
The Seven Deadly Sins of MCP: Design Sins
Duplicate tool names across MCP servers caused errors in openai/openai-agents-python #464. Broken pagination lets very large tool lists come back at once in modelcontextprotocol/java-sdk #615. Capability sprawl is not a cosmetic problem. It directly affects correctness, prompt cost, and the model's ability to make good choices.
