About MCP

MCP is an MCP server published by tenzir in the Developer Tools category: tenzir MCP server.

The repository has 8 stars and 5 forks, with the last commit 6 months ago. Six months or more without a commit doesn't mean the server is broken, but check the open issues before depending on it in production.

README

⚙️ Tenzir MCP Server

PyPI License

A Model Context Protocol (MCP) server that enables AI assistants to interact with Tenzir—a data pipeline engine for security operations.

[!WARNING] This MCP server is not actively maintained right now. tenzir/skills is superseding it and is where new work is happening.

This MCP server provides tools for executing pipelines written in the Tenzir Query Language (TQL)), working with Open Cybersecurity Schema Framework (OCSF), managing packages, generating parsers, and exploring documentation.

✨ Features

  • Pipeline Execution: Run TQL pipelines and tests
  • Documentation Access: Search and browse embedded Tenzir documentation with cross-reference support
  • OCSF Integration: Query and work with OCSF definitions, event classes, objects, and profiles.
  • Package Management: Create and manage Tenzir packages with operators, pipelines, enrichment contexts, and tests
  • Code Generation: Auto-generate TQL parsers and OCSF mapping packages

📦 Installation

Use Docker as the fastest way to get started:

docker run -i tenzir/mcp

Or use uvx when you have a local Tenzir installation:

uvx tenzir-mcp

Questions

About MCP

How do I install MCP?

No package has been published for this server, so install it from source: clone the repository and follow its README.

Is MCP safe to use with an AI agent?

Its trust score is 53 out of 100 (fair). It passes 5 of the 6 static security checks run so far; the failures are listed above. It has no ConduID identity yet, so agent calls to it are not receipted.

Is MCP still maintained?

The last commit was 6 months ago. That's long enough that you should check whether the maintainer is responding to issues before depending on it.
