How to Use the Chord Substitution Finder MCP in Windsurf

Q: How does Chord Substitution Finder help with advanced theory tasks in Windsurf?

It provides three specific tools. First, analyzeprogressiontension maps the harmonic tension across a sequence of chords. Then, you can use findsubstitutions to get all possible chord swaps for any given point. Finally, getsubstitutiondetail gives you the academic breakdown on why that swap works.

Perplexity

Multi-step harmonic analysis.

Need to know the tension arc of a chord progression? Your agent can run `analyze_progression_tension` first, mapping out exactly where the piece builds or falls flat. After that, it figures out available options using `find_substitutions`, letting you see all harmonic swaps for any given chord in one go. Cascade handles the whole sequence without asking you to prompt each step. The result is a clean data output showing both the original tension points and the strongest substitution candidates.

Detailing specific chord replacements.

Once your agent identifies a promising swap, it can dive deeper. Running `get_substitution_detail` pulls detailed explanations for that replacement, explaining *why* that change works within the context of functional harmony. This is useful when you need to justify a complex theory choice. It gives you more than just the chord name; it provides the structural rationale, which means your output can feed directly into documentation or musical notation software.

Chaining analysis with external tools.

Because this MCP runs inside Vinkius's isolated sandbox, you can chain theory checks with other actions. For example, calculate the tension in a progression and then use the resulting substitutions to build code that generates MIDI files or updates a database record. This isn't just reading data; it’s using the theoretical output—the list of viable chords—as an input for another MCP process you're running.

Setup guide

Set up Chord Substitution Finder MCP in Windsurf

Prerequisites

Windsurf IDE installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP configuration

Click the Cascade assistant icon in the sidebar, then click the hammer icon (🔨) at the top of the panel. Select "Configure" to open ~/.codeium/windsurf/mcp_config.json.
2

Add the Chord Substitution Finder MCP

Paste the JSON snippet shown on the right into the mcpServers object. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Refresh MCPs

Go back to the hammer icon (🔨) in Cascade and click "Refresh". Windsurf will detect the new server. No full restart is needed — the connection is hot-reloaded.
4

Verify in Cascade

Start a new Cascade conversation and ask something like "Show my Chord Substitution Finder payment history." If connected, Cascade will call the Chord Substitution Finder tools directly. You will see a green dot next to the server name in the MCP panel.

Common questions about Chord Substitution Finder MCP in Windsurf

It provides three specific tools. First, `analyze_progression_tension` maps the harmonic tension across a sequence of chords. Then, you can use `find_substitutions` to get all possible chord swaps for any given point. Finally, `get_substitution_detail` gives you the academic breakdown on why that swap works.

It provides structured JSON output detailing harmonic relationships. It identifies chords and their potential substitutions while calculating the associated tension level for both the original chord and the proposed change.

Yes. The tools are designed to handle functional harmony analysis across different key centers. You simply input the progression in its original context, and the MCP will calculate substitutions relative to that center.

This server only touches musical theory data; specifically, it reads and writes structured chord progressions and associated harmonic analysis metadata. It never handles user identifiers or personal records.

Absolutely. Because the MCP outputs standardized data, your agent can pipe the tension scores directly into another tool's input field. You aren't just viewing the analysis; you're using it to drive logic.
