Overview

The Oh My Posh Validator MCP server checks oh-my-posh configurations and segment snippets against the official schema. It exposes validation capabilities through MCP so an AI agent can inspect prompt configuration data before it is used. Reach for it when editing or troubleshooting an oh-my-posh prompt and schema conformance matters.

Use cases

  • Validate a complete oh-my-posh configuration before applying it
  • Check a segment snippet while developing a custom prompt
  • Review prompt configuration changes for schema errors
  • Ask an AI agent to inspect oh-my-posh configuration data

Key features

  • Validates complete oh-my-posh configurations
  • Checks oh-my-posh segment snippets
  • Uses the official oh-my-posh schema
  • Returns validation results through MCP

How Oh My Posh Validator works

What Oh My Posh Validator MCP server does

The Oh My Posh Validator MCP server focuses on checking configuration data used by oh-my-posh, a cross-platform prompt theme engine for shells. It covers both complete oh-my-posh configurations and individual segment snippets, comparing them with the official schema.

This makes the server relevant when an agent is helping create, update, or review a customized shell prompt. It addresses configuration validity rather than prompt rendering, shell setup, theme design, or general data processing.

How it works

An MCP-compatible AI client sends an oh-my-posh configuration or segment snippet to the validator.

Validation can be applied at two scopes: a full configuration and a smaller segment snippet. Checking a snippet separately can help isolate an invalid portion of a larger prompt definition before incorporating it into the complete configuration.

Tools and capabilities

The Oh My Posh Validator MCP server supports these documented validation tasks:

  • Validate complete oh-my-posh configurations against the official schema.
  • Validate oh-my-posh segment snippets against the official schema.
  • Return validation results to an MCP client for review by an AI agent.

Treat the server as a schema-validation component rather than a complete oh-my-posh administration interface.

Limitations and notes

The Oh My Posh Validator MCP server is documented only for configuration and segment validation.

Those details should be verified in the project’s current documentation before deployment.

The repository describes oh-my-posh as shell- and platform-agnostic, configurable, and extensible, but those project characteristics do not establish additional capabilities for this validator. They also do not indicate that the MCP server can execute shell commands or manage an existing oh-my-posh installation.
