Overview

Description from the maker (original English)

Read-only Kafka access for AI assistants: topics, consumer groups, schemas, cluster health.

PopNx MCP’s three pillars

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

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Computer or cloud
  • Transport: stdio, Streamable HTTP
  • Category: Databases & datasets
  • You need to fill in: CONDUKTOR_CONSOLE_URL, CONDUKTOR_API_TOKEN, Authorization

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • You fill in yourself: CONDUKTOR_CONSOLE_URL, CONDUKTOR_API_TOKEN, Authorization

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

  • Runs in the cloudNothing to install; it connects over the internet
  • npmNode.js installed (for the npx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Or run it on your computer

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "kafka": {
      "command": "npx",
      "args": [
        "-y",
        "@conduktor/mcp"
      ],
      "env": {
        "CONDUKTOR_CONSOLE_URL": "your-value",
        "CONDUKTOR_API_TOKEN": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add --transport http kafka 'https://{console_host}/api/mcp' --header 'Authorization: Bearer {token}'

Or run it on your computer

claude mcp add kafka --env CONDUKTOR_CONSOLE_URL=your-value --env CONDUKTOR_API_TOKEN=your-value -- npx -y @conduktor/mcp

Fill in the empty values before running it.

The address contains {…} parts that only you know (such as your account), so copy it and fill them in.

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "kafka": {
      "url": "https://{console_host}/api/mcp",
      "headers": {
        "Authorization": "Bearer {token}"
      }
    }
  }
}

Or run it on your computer

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "kafka": {
      "command": "npx",
      "args": [

      ],
      "env": {
        "CONDUKTOR_CONSOLE_URL": "your-value",
        "CONDUKTOR_API_TOKEN": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Common questions

Is Conduktor 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?

You need to fill in: CONDUKTOR_CONSOLE_URL, CONDUKTOR_API_TOKEN, Authorization

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 (1.0.1) reached the registry 32 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: Supabase, MongoDB MCP Server, Elasticsearch MCP Server

Conduktor MCP

Put an AI assistant in charge of your Kafka estate.

Not a chat window onto a cluster. A way for agents — yours, or ours — to see what is actually happening across every cluster you run, and to act on it: reclaim the topics nobody consumes, attribute cost back to the teams spending it, catch the certificate expiring next month, restart the connector that failed at 3am, label the topics whose owner left the company.

The MCP endpoint ships inside Conduktor Console. There is nothing to deploy, and nothing new to secure: the assistant inherits the RBAC, audit trail and ownership model you already run.

Try it first

No Kafka to hand? demo/ brings up a cluster, Console and the MCP endpoint with docker compose up -d, seeded with topics, traffic and a consumer group that is deliberately behind.

Setup

Create a Personal Access Token in Console, then point your MCP client at your own Console:

{

"mcpServers": { "conduktor": { "command": "npx", "args": ["-y", "@conduktor/mcp"], "env": { "CONDUKTOR_CONSOLE_URL": "https://console.acme-corp.com", "CONDUKTOR_API_TOKEN": "your-personal-access-token" } } } }

/api/mcp is appended for you. Pasting a URL that already ends in it works too.

Connecting without the package

@conduktor/mcp wraps mcp-remote. Call it yourself if you prefer:

{

"mcpServers": { "conduktor": { "command": "npx", "args": [ "mcp-remote", "https://console.acme-corp.com/api/mcp", "--header", "Authorization: Bearer ${CONDUKTOR_API_TOKEN}" ], "env": { "CONDUKTOR_API_TOKEN": "your-personal-access-token" } } } }

What an assistant can ask

Ask in English, get answers grounded in your actual estate rather than in documentation:

*Which topics haven't been consumed in a month, and who created them?*

*What did the payments team cost us last quarter, and what drove it?*

*This consumer group is stuck — what's the blocking message?*

*Which certificates expire before March, and whose are they?*

*Nobody owns these topics. Can you work out who should, from the lineage?*

Those are not demos. Each maps onto tools below, and onto tasks an agent can run unattended.

From answering to operating

The same catalogue serves two kinds of caller. Your tools — Claude Code, Cursor, scripts, your internal developer platform — and agents running inside Console, on a schedule or on an audit-log event, under their own machine identity.

That second one is where this stops being a chatbot. An agent is a task plus an identity plus a bounded set of tools. It wakes up on Monday at 9am, or the moment a connector fails, works the problem, and comes back with something you can act on — a report, a recommendation, or a mutation it proposes and you approve.

Every run is traced end to end: the prompt, each tool call, the tokens, the result. That is what you attach to a ticket, or hand to an auditor.

Tools

Thirty-one, across the whole control plane. Most read; some write, and that set is growing.

Clusters
ToolWhat it does
list-clustersEvery Kafka cluster this Console manages, with its Schema Registry, Connect clusters and flavor
get-clusterOne cluster's registration by slug
insights-clusterHealth score, topic and partition counts, serialization breakdown — the shape of a cluster in one call
Topics
ToolWhat it does
list-topicsTopic catalogue: names, labels, descriptions, partitions, replication, configs
get-topicOne topic by exact name
list-topics-with-usageTopics with message count, size and throughput
query-topicsFilter topics across a cluster
aggregate-topicsGroup topics and compute a statistic per group — count, sum, average, min, max
insights-topicsPartition skew, replication problems, and what is quietly wrong
set-topic-labels (writes)Label topics — ownership, environment, whatever your taxonomy is
Messages
ToolWhat it does
get-last-messagesThe last N messages from a topic
get-record-atA specific record, by partition and offset — the one blocking a consumer
Consumer groups
ToolWhat it does
list-consumer-groupsGroups with state, lag and member count
get-consumer-groupOne group in detail
list-consumer-groups-by-topicWho actually reads this topic
Schemas
ToolWhat it does

get-stream-lineageWhat flows into what
query-audit-logWho did what, when
get-chargeback-reportCost attributed per team

Security is what makes this possible

Giving an agent real access to production is only reasonable because the boundaries already exist and are enforced per call.

It is you. Every call carries a Console token and runs under that user's RBAC. An agent cannot see a cluster its owner cannot see. Revoke the owner's access and the agent loses it at the same instant.

Control plane, not data plane. What reaches the model is metadata — topics, configs, offsets, groups, schemas, lineage, cost. Your records stay in Kafka unless a task explicitly needs a tool that reads them.

Everything is audited. Every call lands in the Console audit log, attributable to the identity that made it.
