For TypeScript you can refer to https://github.com/modelcontextprotocol/typescript-sdk/blob/...

There isn't much documentation available right now but you can ask coding agent eg. Claude Code to generate an example.

@modelcontextprotocol/sdk: MCP server framework

At the time of this writing, this is little more than a proof of concept as a combination of the starter Pulsar package-generator package, the Atom package creation tutorial and the example from the official MCP Typescript SDK with some editor tool functions registered. Hopefully it will become more soon, since I am looking forward to actually using it to build stuff!

MCP TypeScript SDK

For this, we're going to use McpServer from the modelcontextprotocol SDK. The SDK supports: Resources, Tools, Prompts. However for this demo we'll only need tools.

Building a custom MCP server is straightforward with the right tools. While servers can be written in any language supporting stdout, official SDKs simplify the process. The TypeScript SDK is a great starting point.

For me it was implementing a simple `execute_terminal_command` tool along with hooking up to my company's jira and gitlab (dont worry security gurus, for the command line, I have a hardcoded list of allowed read-only commands that the LLM can execute, and both jira and gitlab servers likewise have readonly options.

What I will say is I agree there should be an option to get rid of the chat confirmations of every single new tool call in a chat - as well as building a set of "profiles" of different tools depending what I'm working on. Also strongly agree there needs to be an internal prompt possibility to explicitely tell the LLM what tool(s) to favor and how to use them (even in addition to the descriptions / schemas of the tools themselves) I opened an issue on the anthropic repo exactly about this: https://github.com/modelcontextprotocol/typescript-sdk/issue...

MCP already has a few SDKs you can start using. For this blog post we will use the MCP Python SDK.

In my case I used the MCP Python SDK:

Create your MCP server: Use your favorite programming language. We went with the Python SDK.

I couldn't understand the hype around MCP so I decided to build a simple server for Outlook (requires admin in Azure).

For the build I just used a Python MCP SDK: https://github.com/modelcontextprotocol/python-sdk

Now, I'm not a fast dev. Still, in 2 days I had Claude Desktop filing and responding to emails better than any assistant I've worked with (human or otherwise). None of this was due to my skill. I was basically just wrapping msgraph calls in the same @mcp.tool decorator over and over.

In fact, I spent more time fiddling with msgraph auth & api-calls than I did on the MCP server itself.

Today, in a typical workflow, I just tell Claude to "sort my inbox" and it handles everything from filing mails, creating folders, writing responses, scheduling meetings, flagging actions, etc.

For anyone wondering about MCP, the following struck me:

Python SDK

However, just a few days ago on May 8, 2025, v1.8.0 of the MCP Python SDK was released, officially supporting the long-awaited Streamable HTTP transport. The release notes proudly declare, "This is the first release supporting the new Streamable HTTP transport from protocol version 2025-03-26, which supersedes the SSE transport from protocol version 2024-11-05. 🎉", signaling a significant milestone in MCP's communication protocol.

MCP servers MCP servers act as bridges between your data sources and AI agents. They expose APIs, databases, or custom code as tools (or resources) that an MCP host can use. Servers can be built using their Python or TypeScript SDKs, making it flexible for developers to work with their preferred language.

SDKs make building and integrating MCP clients and servers easy. While there isn't an official SDK for Go yet, the community-built mark3labs/mcp-go has been gaining a lot of popularity among Go developers—including myself.
