typescript-sdk

LM Studio. No additional software but I implemented the MCP client myself using the typescript-sdk[0] 0. https://github.com/modelcontextprotocol/typescript-sdk

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.

The worst thing is issues without any visibility. The other day I was toying with the MCP server (https://github.com/modelcontextprotocol/typescript-sdk). I default to bun these days and the http based server simply did not register in claude or any other client. No error logs, nothing. After fiddling with my code I simply tried node and it just worked.

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/modelcontextprotoco

Its trivial to write your own server with one of the MCP server SDKs. I used https://github.com/modelcontextprotocol/typescript-sdk

We are still a bit light on documentation on how to integrate MCP into an application. The best starting point are the respective client parts in the SDK: https://github.com/modelcontextprotocol/typescript-sdk/tree/... and https://github.com/modelcontextprotocol/python-sdk/tree/main..., as well as the official specification documentation at https://spec.modelcontextprotocol.io. If you run into issues, feel free to open a discussion in the respective SDK repository and we are happy to help. (I've been fairly successful in taking the spec documentation in markdown, an SDK and giving both to Claude and asking questions, but of course that requires a Claude account, which I don't want to assume)

Both Python and Typescript SDK can be used to build a client. https://github.com/modelcontextprotocol/typescript-sdk/tree/... and https://github.com/modelcontextprotocol/python-sdk/tree/main.... The TypeScript client is widely used, while the Python side is more experimental. In addition, I recommend looking at the specification documentation at https://spec.modelcontextprotocol.io. This should give you a good overview of how to implement a client. If you are looking to see an implemented open source client, Zed implements an MCP client: https://github.com/zed-industries/zed/tree/main/crates/conte... If you have specific questions, please feel free to start a discussion on the respective https://github.com/modelcontextprotocol discussion, and we are happy to help you with integrating MCP.
