Produce records to a Kafka topic

Part of the Confluent Kafka MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

WHEN AI AGENTS USE THIS TOOL

AI agents use produce-message to create or modify resources in Confluent Kafka. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.

WHY ENFORCE A POLICY ON PRODUCE-MESSAGE

Without a policy, an AI agent could call produce-message repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Confluent Kafka.

RECOMMENDED POLICY

Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

      - action: allow
        rate_limit:
          max: 30

FREQUENTLY ASKED QUESTIONS

What does the produce-message tool do?

Produce records to a Kafka topic. It is categorised as a Write tool in the Confluent Kafka MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on produce-message?

Add a rule in your Intercept YAML policy under the tools section for produce-message. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Confluent Kafka MCP server.

What risk level is produce-message?

produce-message is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit produce-message?

Yes. Add a rate_limit block to the produce-message rule in your Intercept policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block produce-message completely?

Set action: deny in the Intercept policy for produce-message. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides produce-message?

produce-message is provided by the Confluent Kafka MCP server (@confluentinc/mcp-confluent). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
