Overview

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

Common questions

Is Izzet Yildirim safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.2) reached the registry 13 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Context7, Codebase Memory, Exa

iyildirim

An MCP server for Izzet Yildirim. Connect it to your AI agent and ask about his research, papers, CV, and availability.

It is read-only and needs no sign-in. It answers from the public data on iyildirim.com, including the full text of his published papers.

Connect

Claude Code

claude mcp add iyildirim -- npx -y iyildirim

Claude Desktop, Cursor, VS Code, Windsurf (any client that launches local servers): add to the MCP config.

{

"mcpServers": { "iyildirim": { "command": "npx", "args": ["-y", "iyildirim"] } } }

No install: most clients can connect straight to the hosted server, which is what this package forwards to.

claude mcp add --transport http iyildirim https://iyildirim.com/api/mcp

Claude, ChatGPT, and Cursor also accept https://iyildirim.com/api/mcp as a custom connector URL.

Then ask

What has Izzet published on I/O tracing?

Read the system design section of the AgentStage paper and summarize it.

Is Izzet a fit for this role? (paste a job description)

Tools

ToolWhat it does
get_cv_sectionOne section of his CV: experience, education, service, certifications, or skills
get_paper_sectionThe text of one section of a public paper
get_profileStart here: overview, what he is looking for, contact, links
get_publicationThe catalog entry for one publication (summary, venue, abstract, links)
list_paper_sectionsThe sections of a public paper
search_paper_textSearch the full text of public papers for passages
search_publicationsSearch the publication catalog by topic, system, or venue

How it works

This package is a thin stdio-to-HTTP bridge. It holds no tools or data of its own: each message goes to https://iyildirim.com/api/mcp and the reply comes back unchanged, so the tools are always as current as the site. No dependencies.

Set IYILDIRIM_MCP_URL to point it at another endpoint, for example a preview deployment.

Develop

npm install

npm run validate # format check, types, tests, build

Release

Releases are published to npm, and then listed in the official MCP registry as io.github.izzet/mcp, by publish.yml when a version tag is pushed.

  1. Bump version in package.json and in server.json (both version and packages[0].version) in a pull request and merge it. A test and the workflow check that they match.
  2. On main: git tag v0.1.1 && git push origin v0.1.1 (the tag must match the version).

Publishing needs either a trusted publisher configured for this repo and publish.yml on npmjs.com (no secret), or an NPM_TOKEN repository secret.
