Agent Blast Radius in Claude Code

Install the plugin: the blast MCP tools plus a skill that tells Claude how to scan, explain and verify.

What you need

• macOS or Linux (ARM64 or AMD64)
• Node.js 22 or newer on your PATH (nodejs.org; the installer puts it where desktop apps can find it)
• Claude Code

Install

1. Add the marketplace and install the plugin

   In a Claude Code session:

   /plugin marketplace add makash/agent-blast-radius
   /plugin install agent-blast-radius@kloudle

   Copy

2. Restart Claude Code

   Quit and start claude again so the MCP server loads.

Alternative: MCP server only (no skill)

1. Add it from your shell

   claude mcp add blast -- npx -y @kloudle/agent-blast-radius@0.3.0 mcp

   Copy

Check it works

1. List MCP servers

   Run /mcp. blast should be connected with 6 tools.

Try it

Paste into Claude Code:

Run the Agent Blast Radius scan on this machine and show me the headline counts, then make the share card.

The scan is offline and read-only. It reports credential types, locations and fingerprints, never values.

Check which keys are live

Paid, optional: $0.10 USDC per check on Algorand with your own wallet. Install GoPlausible's Algorand plugin so Claude can pay from its own wallet, or pay in the browser.

Check which of my credentials are live with paid verification. Tell me the price and the code before paying.

Uninstall

1. Remove the plugin and marketplace

   /plugin uninstall agent-blast-radius@kloudle
   /plugin marketplace remove kloudle

   Copy

Troubleshooting

blast shows as failed in /mcp

Check node --version is 22+, then run npx -y @kloudle/agent-blast-radius@0.3.0 --version in a terminal to see the real error.
