How to Use the Chord Progression Analyzer MCP in Claude Code

Q: How do I check a progression pattern using Chord Progression Analyzer with Claude Code?

You simply pipe the chords into analyzeromannumerals first. Then, use classifyprogression on the resulting Roman numerals to get the harmonic map. The output is ready for piping to other tools.

Q: Can I check musical context in Claude Code using Chord Progression Analyzer?

Yes. After you classify a progression with classifyprogression, pipe that output into lookupmusicalcontext. This gives the stylistic metadata needed for your automation script.

Q: Is Chord Progression Analyzer suitable for CI/CD in Claude Code?

Absolutely. You can build multi-step pipelines: analyzeromannumerals -> classifyprogression -> lookupmusicalcontext. The entire flow is non-GUI and easily scriptable.

Run deep music theory pipelines using Claude Code in your terminal.

Perplexity

Execute full harmonic analysis via the MCP Server

Use a single command to run complex analyses for CI/CD. First, pipe chords into `analyze_roman_numerals` to get functional Roman numerals. Then, feed those results directly to `classify_progression`. The entire sequence runs headless and prints the resulting harmonic pattern to stdout. This makes it perfect for automated checks in a Docker container or GitHub Action.

Validate musical context using Claude Code

Need to check if a progression is appropriate for a certain mood? Run `analyze_roman_numerals` for the key, then execute `classify_progression`. Pipe that output into `lookup_musical_context`, and you get the stylistic metadata—all in one terminal command. It's ideal for backend services that need to validate creative assets before deployment.

Process large datasets with the MCP Server

Don’t run manual checks. Script a job that iterates through thousands of chords, using `analyze_roman_numerals` on every entry. Group those results, and then pipe the consolidated list to `classify_progression`. You get an aggregated report of harmonic patterns. This level of automated processing is what makes it useful in cron jobs or batch scripts.

Setup guide
