How to Use the Chord Substitution Finder MCP in Claude Code

Q: How do I integrate Chord Substitution Finder into a CI/CD pipeline using Claude Code?

You can run it headless via command line. First, use analyzeprogressiontension to get the metrics. Then, call findsubstitutions and pipe the resulting data stream directly into another script for processing.

Perplexity

Batch processing harmonic analysis.

For CI/CD pipelines, you can script a full progression review. Start by calling `analyze_progression_tension` on a large input file to generate tension metrics for every chord. Next, pipe that data into `find_substitutions`, which will output all possible harmonic replacements in a machine-readable format. This allows your scripts to automatically validate or suggest musical changes at scale without any manual intervention.

Generating structured music theory reports.

Don't just get a list of chords. Use `get_substitution_detail` to generate comprehensive, technical report sections for your scripts. You can script the function to loop through 50 substitutions and output a detailed explanation for each one. The result is highly structured text perfect for appending to documentation or generating Markdown files.

Automating theory validation in pipelines.

You need to check if an uploaded piece adheres to certain harmonic rules? Write a script that uses `find_substitutions` to validate the chords against your allowed set. If a chord has no valid substitutions or falls outside expected parameters, the script fails gracefully. This makes the MCP perfect for automated quality checks in music data pipelines.

Setup guide

Common questions about Chord Substitution Finder MCP in Claude Code

You can run it headless via command line. First, use `analyze_progression_tension` to get the metrics. Then, call `find_substitutions` and pipe the resulting data stream directly into another script for processing.

Yes. The MCP focuses on harmonic function rather than strict rhythmic measure counts, so long as you define the chord sequence and its key center, it will process it accurately for substitutions.

It’s perfect for generating technical documentation. Your script can automatically call this function to append detailed, academically sound justifications into a report file that proves why certain chords were chosen.

This server processes musical theory metadata. It reads and writes chord progressions, tension metrics, and harmonic analysis outputs. There is zero interaction with user credentials or private system files.

Yes. The MCP exposes tools in a sequence that your script can manage. You get clean, verifiable output from one tool call that is ready to be ingested by the next tool call in your shell script.
