AI & MCP

Umfeld is an MCP CRM: give your AI knowledge about your network

Connect Umfeld to Claude, and your AI knows your network: who knows whom, when you last met, what you talked about. No digging through old notes, no copy-pasting.

Most AI assistants know only what you type into the chat about your network. Umfeld gives them access to what you have written down for years.

Give your AI knowledge about your network

The examples below show what a conversation with Claude looks like once Umfeld's MCP server is connected. The names are invented, the pattern of the answers is not.

Who do I know at Contentful?

Two people: Jonas Reuter, who you met at a conference in 2022 and who is now Head of Product there, and Mira Salet, who Anna Brandt introduced you to in March. You last spoke with Jonas in January.

When did I last see Anna, and what did we talk about?

You had dinner on June 14th. Your note says the conversation was about her job change and her daughter starting school.

Who should I reach out to again?

Three contacts are cooling off: Peter Soto, last contact four months ago, your mentor Carlo Vella, three months, and Mara Lin. Peter was about to change jobs last you heard, that's a good reason to check in.

Who do I know that could introduce me to someone at Raycast?

Nobody directly. But according to the relationship graph, your contact Jonas Reuter knows two people there, including a former colleague. You could ask him for an introduction.

What an MCP server means for your address book

Umfeld is, at its core, a personal CRM: it syncs your Google Contacts in both directions and adds a relationship graph, an interaction log, life events, tags, and a health score that shows which connection is cooling off.

The Model Context Protocol, MCP for short, is an open standard that lets AI clients like Claude reach external tools and data. Umfeld runs its own MCP server at https://api.umfeld.app/mcp, secured with OAuth. About 58 tools sit behind it: search contacts, get contact details, create relationships, log interactions, find cooling contacts, search notes by meaning, and more.

The MCP server runs, like the rest of Umfeld, as a hosted service from Europe, see EU hosting.

Connect Claude in three steps

1
Copy the MCP server URL
In Umfeld, under Connections, you'll find the address https://api.umfeld.app/mcp. One click copies it.
2
Add it as a connector in Claude
In Claude, open Settings, then Connectors, then Add custom connector, and paste the URL.
3
Confirm access
Claude opens an OAuth dialog. Once you confirm, Claude has read and write access scoped to your account, and you can ask about your network directly in the chat.

MCP configuration for developer clients

Editor-based MCP clients such as Claude Code read a JSON configuration with the same server entry. Claude Desktop and Claude on the web use the connector dialog from the steps above instead, but they accept the same URL.

{
  "mcpServers": {
    "umfeld": {
      "type": "http",
      "url": "https://api.umfeld.app/mcp"
    }
  }
}

What the AI is actually allowed to do

Access runs through OAuth and is scoped to your account. You decide per client whether it can read and write, and you can revoke the connection at any time. Details for each client are on Connect your AI.

Why a graph gives better answers than a pile of notes

A notes document like the ones in Notion stores text, not relationships. An AI can search inside it, but it still has to guess who is connected to whom and how current a piece of information still is.

In Umfeld, relationships, dates, and context are typed fields instead of prose. Claude can ask exactly who introduced whom, or when your last meetingwas, and get a precise answer instead of a guess. That's what makes the relationship graph the real difference.

What's structured

Relationships between contacts: who knows whom, since when, how you met
An interaction log with dates and short notes
Life events and tags
A health score for cooling contacts

Frequently asked questions

Does Umfeld need its own AI or an OpenAI subscription?

No. Umfeld connects to the AI client you already use, such as Claude. You don't need a separate AI subscription from Umfeld itself.

Does this work with ChatGPT too?

Yes, through Connectors or ChatGPT's developer mode. A step-by-step guide per client is on the Connect your AI page.

Can Claude see my private notes?

No. Entries marked private are excluded from MCP access and never appear in an answer.

Where does the data behind the MCP server live?

In Europe. Umfeld runs exclusively as a hosted service, and the MCP server runs on the same infrastructure as the rest of your account.
