Overview

AI-generated overview

Remote MCP endpoint offering deterministic utilities: evidence verification, JSON Schema validation, SHA-256 hashing, and paid variants with crypto wallet…

What you can do
  • Verify supplied structured evidence and get a machine-readable verification result
  • Validate structured data against a customer-supplied JSON Schema Draft 2020-12 subset, with bounded errors
  • Compute reproducible SHA-256 digests for supplied UTF-8 or base64-decoded bytes
  • Provision a free Blue Cap machine wallet on Base Mainnet (USDC)
  • Obtain Stripe payment links for the paid versions of verification, validation and hashing
When to use it
Useful when an assistant needs reproducible, receipted checks — confirming evidence, validating data against a JSON Schema, or hashing bytes — and the caller is willing to use a hosted third-party endpoint, including paid per-call variants.
Requirements
A remote streamable HTTP endpoint at machine.soundiq.io; no packages, environment variables or headers are declared. The paid tools require a Stripe payment link flow and a wallet on Base Mainnet (USDC).
Before you install
The server provisions a crypto wallet on Base Mainnet and offers paid capabilities through Stripe payment links, so calls can involve spending money and wallet handling. Data submitted for verification, validation or hashing is sent to a third-party service. No authentication is declared, so review what you send before using it.

Installation

In SourceWeft

  1. Open Blue Cap Machine Commerce in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.soundiq%2Fbluecap-evidence-verify/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows
