Install guide — Wolfgang Rush MCPB Desktop Extensions

← Back to MCPB family

This guide installs any of the 14 Wolfgang Rush MCPB Desktop Extensions into the Claude Desktop App on Mac or Windows. Three steps.

Step 1 — Download the .mcpb file

  1. Visit the GitHub repo for the extension you want (e.g. indian-hc-drafting-mcpb)
  2. Click Releases in the right sidebar
  3. Click the latest release (e.g. v0.1.5-alpha)
  4. Under Assets, click <extension-name>.mcpb to download. The file is ~200 KB.

Step 2 — Install into Claude Desktop App

  1. Open the Claude Desktop App on Mac or Windows.
  2. Click the gear icon (Settings) — top-left on Mac, top-right on Windows.
  3. In the left sidebar, click Extensions. ⚠️ Do NOT click Plugins (that is a different ecosystem — Claude Code plugin format, not MCPB).
  4. Click Install Extension.
  5. In the file picker, navigate to where you downloaded the .mcpb file. Select it. Click Open.

You should see:

Step 3 — Verify the install with a test invocation

  1. Open a fresh chat in Claude Desktop.

  2. Type one of these depending on which extension you installed:

    • HC: Using the indian-hc-drafting plugin, list all the case types you can draft.
    • SC: Using the supreme-court-drafting plugin, list all the case types you can draft.
    • Tax: Using the indian-tax-drafting plugin, list all the case types you can draft.
    • (similarly for any other extension)
  3. Claude should announce it’s calling the extension’s tools, invoke list_case_types, and return the case-type catalogue. That confirms the round-trip works.

Step 4 — Draft your first pleading

Attach your source document (FIR / impugned judgment / notice / draft assessment order / etc.) to the chat. Then type something like:

Extension Sample prompt
HC Draft a Section 482 CrPC application before Delhi High Court for quashing the attached FIR. Use the indian-hc-drafting plugin.
HC Draft a regular bail application before Bombay High Court Nagpur Bench for the attached FIR. Use the indian-hc-drafting plugin.
SC Draft a Special Leave Petition (Criminal) before the Supreme Court against the attached High Court judgment. Use the supreme-court-drafting plugin.
District Draft an anticipatory bail application before the Sessions Court, [your district], for the attached FIR. Use the district-court-drafting plugin.
Family Draft a divorce petition under Section 13 HMA before the Family Court, [your district]. Use the indian-family-drafting plugin.
Consumer Draft a consumer complaint before the District Consumer Forum at [your district] against the attached deficiency of service. Use the indian-consumer-drafting plugin.
MACT Draft a Section 166 MV Act claim before the MACT at [your district] for the attached accident facts. Use the indian-mact-drafting plugin.
Tax Draft a Form 35 CIT(A) appeal against the attached assessment order. Use the indian-tax-drafting plugin.
Rent Control Draft an eviction petition on bona-fide personal need ground before the Court of Small Causes at [your city] against the attached tenant. Use the indian-rent-control-drafting plugin.

The plugin will:

  1. Call get_agent_instructions() to load the full pipeline orchestration script
  2. Call create_case_folder(case_type, bench-or-state) — creates ~/Downloads/Wolfgang-Rush-Drafts/<case-type>-<jurisdiction>-<timestamp>/
  3. Save your input documents into inputs/ of that folder
  4. Run the six agents in sequence: Reader → Format → Drafter → Verifier → Refiner → Overseer
  5. Save six artifacts in the case folder (case-facts.md, format-shell.md, draft-v1.docx, verification-report.md, draft-v2.docx, opposing-notes.md, final-draft.docx)
  6. Report the path to final-draft.docx

Where your files go

All output lives at:

Each session creates a new timestamped folder. Nothing leaves your machine.

Updating

When a new version of an extension is released:

  1. Download the new .mcpb file from the release page
  2. Settings → Extensions → Uninstall the previous version
  3. Install Extension → pick the new .mcpb file

(In-place upgrade is not yet supported — uninstall + reinstall is the path.)

Troubleshooting

“Plugin validation failed” toast — you opened the wrong panel. Settings → Extensions is the right one. Settings → Plugins / Directory → Plugins is a different ecosystem.

Extension installed but Claude doesn’t invoke it — name the plugin explicitly in your prompt: “using the indian-hc-drafting plugin”. Claude needs the hint to select tools.

Output is wrong case-type — check the acronym disambiguation table and name the case-type explicitly (e.g. “Section 482 CrPC application for quashing” rather than just “APL”).

Output formatting wrong (wrong page size or font) — the extension ships a reference.docx with A4 + Georgia 14pt + 2cm margins baked in. If your output is on US Letter, you have an older version of the extension installed — uninstall and reinstall the latest.

Other issues — open an issue on the relevant GitHub repo.
