Background & analysis
On November 5, 2026, a developer published a post on DEV Community introducing mcp-server-starter, a TypeScript starter template released under the MIT license. The author had previously built MCP servers for LinkedIn, Twitter/X, Medium and Kaggle, and found that most of what went wrong with them was not the API logic but small plumbing mistakes that the usual starters do not protect you from.
The article identifies the most typical failure as follows: under the stdio transport, any console.log pollutes the JSON-RPC stream, which makes the client raise parsing errors, return an empty tool list, or drop the connection without warning. The fixes are collected into mcp-server-starter: it uses registerTool from SDK 1.x with zod for input validation, and converts exceptions thrown by the handler function into model-readable error results.
This is the only report so far, and there are no further developments to report.

After building MCP servers for LinkedIn, Twitter/X, Medium and Kaggle, the author packaged the recurring plumbing mistakes into an MIT-licensed TypeScript starter called mcp-server-starter. The most common failure, it says, is a stray console.log polluting the JSON-RPC stream under the stdio transport, which surfaces as parse errors, an empty tool list or a silent disconnect. The starter uses the SDK 1.x registerTool API with zod validation and turns handler exceptions into error results the model can act on.
