Overview

AI-generated overview

Local MCP server that verifies post-transaction outcomes and scores agent service quality with an LLM-as-judge.

What you can do
  • Verify outcomes after a transaction completes.
  • Judge the quality of agent service using an LLM-as-judge approach.
  • Record and read quality data through a Supabase-backed quality database.
  • Accept USDC payments to a configured Solana wallet address.
  • No individual tools are listed in the manifest, so the exact operations are not documented.
When to use it
Consider it when you need an assistant to check whether a transaction produced the expected result, or to score the quality of agent-delivered service and keep those scores in a shared database.
Requirements
Runs as a local process from the npm package @meltingpixels/harvey-verify (Node.js runtime implied). Needs SUPABASE_URL and SUPABASE_SERVICE_ROLE_KEY for the quality database, XAI_API_KEY for the Grok-based judge, and optionally PAYMENT_WALLET, a Solana address for receiving USDC. Desktop only.
Before you install
Requires a Supabase service role key, which grants broad database access, and an xAI API key; both are secrets passed by environment variable. A payment wallet address is configured for receiving USDC, so payment flows may move real funds. Verification and judging send data to Supabase and to xAI's API. No tools are documented, so review what it writes before use.

Installation

In SourceWeft

  1. Open Harvey Verify in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Score

25% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
