Install the plugin

The plugin ships as an .mcpb Desktop Extension. You build it from the repo, then drag it into Claude Desktop. Make sure you've covered Before you begin first — you need uv installed.

1. Build the bundle

git clone https://github.com/PrimeDeltaCorp/primedelta-mcp.git
cd primedelta-mcp/mcpb
npm i -g @anthropic-ai/mcpb   # the bundler, once
./build.sh                    # produces primedelta-mcp.mcpb

build.sh writes primedelta-mcp.mcpb in the mcpb/ directory.

2. Add it to Claude Desktop

Open Claude Desktop → Settings → Extensions, then drag primedelta-mcp.mcpb into the window (or double-click the file). Claude Desktop collects the configuration through its own UI on install — see Configure the plugin.

First launch takes a moment

The bundle ships source and resolves its Python environment with uv on first run — expect a minute or two the first time, with network access. Subsequent launches are fast.

3. Your key stays in the keychain

If you use privatekey or aws signing, the sensitive value is stored in your OS keychain, never written to a plaintext config file. In the default browser mode, no key is stored at all — your wallet holds it.

What "installed" looks like

Once it's running, ask Claude:

What's my session status?

You should get back your network, signing mode, whether a signer is configured, and your active caps and gates. If the signer is missing or the network is wrong, fix it in Configure the plugin. If something errors, see Plugin troubleshooting.
