What is the Triple MCP server?

TypeScript definitions for triple-beam. The triple mcp server wraps that behind the Model Context Protocol, so an assistant can use it through 10 defined tools rather than through you.

What it actually does

The goal of this repo is not to include .d.ts files for every package on npm, just those that are actually in use today, by real TypeScript authors. Your motivation for new definition PR must be that you intend to consume these types in your own project. "Make-work" PRs that do not appear to be motivated by concrete usage will be closed, and spamming the repo with unmotivated PRs will result in a block.

Its toolset

Everything the assistant can do here goes through one of these:

  • Tag — Version
  • latest — 16.9.23
  • ts2.0 — 15.0.1
  • ts2.5 — 16.0.36
  • ts2.6 — 16.4.7
  • ts2.7 — 16.4.7
  • File — Purpose
  • index.d.ts — This contains the typings for the package
  • Testing — Before you share your improvement with the world, use the types yourself by creating a typename.d.ts file in your project and filling out its exports:
  • Naming — If you are adding typings for an npm package, create a directory with the same name. If the package you are adding typings for is not on npm, set

Adding it to your client

Installation goes through your MCP client rather than a global install: point it at dts-gen on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.

When to reach for it

Plenty of file and storage access servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Triple's toolset — Tag, latest, ts2.0 and 7 more — is a fair guide to whether it matches your workflow. It is maintained by types; worth a glance at recent repository activity before you build anything load-bearing on it.

SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.

Caveats

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • With 10 tools registered it takes up a noticeable share of the context window; turn it off in projects that never touch Triple.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the triple mcp server does with a few real requests.

Frequently asked questions
