cdtm-mcp

An MCP server for the CDTM Community Portal, so you can search CDTM students and alumni from Claude Code, Claude Desktop, or any other MCP client.

Instead of clicking through filter dropdowns, you just ask:

"find me CDTM people building AI agents who can help with fundraising"

and Claude figures out the right tags, queries the portal, and gives you names, headlines, and profile links.

Why I built this

Hi, I'm Hamza (Fall 2017, co-founder at ZenML). The community portal is genuinely useful — a few thousand people with skills, interests, and "can support with" tags — but I never remember to open it. I do live in Claude Code all day, so I wired the portal into it as an MCP server. Now finding "alumni in Munich who know venture capital and offer mentoring" is one sentence away, and Claude can cross-reference results with whatever else I'm working on.

If you find this useful, give it a star ⭐ — if enough people do, I'll ask the CDTM team for a proper way to integrate this into the internal app (API tokens instead of the cookie dance below).

Setup

You need Python 3.10+ and uv (or plain pip).

git clone https://github.com/htahir1/cdtm-mcp.git
cd cdtm-mcp

Getting your session cookie

The portal sits behind oauth2-proxy, and there's no public API or token system (yet — see the star pitch above). So the server authenticates with your own browser session cookie:

1. Log in to internal.cdtm.com in your browser.

2. Open DevTools (F12) → Network tab → reload the page.

3. Click any request to internal.cdtm.com → Headers → find the Cookie request header.

4. Copy the part that starts with _HOST-oauth2-proxy= (it's long).

5. Create a .env file in the repo root:

CDTM_COOKIE='_HOST-oauth2-proxy=<paste the value here>'

The cookie expires after a while. When the tools start failing with an auth error, repeat the steps. .env is gitignored — keep it that way, this cookie is your login.

Registering with Claude Code

claude mcp add --scope user cdtm -- uv run --directory /path/to/cdtm-mcp python server.py

That's it. Open a new Claude Code session and ask it something.

For Claude Desktop, add the equivalent command to your claude_desktop_config.json.

What it can do

Example prompts that work well:

• "find CDTM people into agentic AI"

• "who from the Fall 2017 class is in Berlin?"

• "alumni who can support with pitch feedback and know climate tech"

• "pull the full profile for the person I just found"

How it works

Nothing fancy. The portal is a Next.js app whose search runs through its own JSON endpoint (/api/protected/directory?skills=414&interests=62&q=...). This server:

• pulls the tag taxonomy (names → IDs) out of the /home page payload once per session

• resolves the human-readable tag names Claude picks into IDs

• calls the directory endpoint and returns clean JSON

• parses profile pages server-side for get_member_profile

No scraping of anything you couldn't see in your own browser, no data stored anywhere.

A note on being a good citizen

This reads member-provided data through your own authenticated session. It's for finding people to talk to — not for bulk-exporting the directory or spamming anyone. Don't be that person.

This is an unofficial community project and isn't affiliated with the CDTM team. If they have any concerns about it, or want to talk about a proper API, I'm happy to hear from them.
