MCP servers

fabric-verify-mcp

by AugmentEVzero

An MCP server that signs a short record of each action your AI agent takes, using a key held on your own machine, and adds it to a public log. You can later get a proof that anyone can check offline to show a record existed unchanged by a certain time.

New and promisingUnder two months old. Expect rough edges and fast changes.

What you can do with it

  • Record signed, timestamped entries for actions your AI agent performs
  • Fetch proofs that anyone can check offline using the free verifier
  • Export a bundle of agent events with proofs for an auditor or client

Make money with it

A freelancer building AI agents for clients could offer verifiable audit records as an added service, passing on the small per-record cost.

An idea, not financial advice. Check the licence before charging for anything built on it.

Ways a business could use it

  • Give clients evidence of what an automated agent did on their behalf, to support accountability and dispute handling
  • Keep an audit trail of agent approvals and tool calls for compliance or internal review

Can you use it commercially?

Free to use, change and sell, including in paid products. Keep the copyright notice.

Not legal advice. Read the project's licence file before building a product on it.

Add it to Claude Code

claude mcp add fabric-verify -- npx -y @augmentev/fabric-verify-mcp

It needs FABRIC_CREDIT_KEY (a secret key). A key usually means a paid or sign-up service behind it, so check its pricing.

From the official MCP Registry (ai.augmentev/fabric-verify). Only connect MCP servers you trust: they can act on your behalf.

Getting it running

Needs Node.js 20 or later; add it to your MCP client config using npx, with a prepaid credit key bought from AugmentEV.

Follow the official instructions in the project README.

Things to check

  • Needs a paid prepaid credit key ($0.005 per record)
  • Depends on a hosted service run by AugmentEV and its public log
  • Records in the log are permanent, so personal data must never go in agent or key names
  • A proof shows a record existed unchanged, not that its contents are true
  • Very new project with no stars

earshot Leonxlnx
New and promising

Earshot is a toolkit that lets AI coding agents analyse and describe audio, check how well sound fits a description or a video, and create their own sound effects in code. It runs locally on a CPU as a command-line tool, a Python library or an MCP server.

cueframe-mcp cueframe-ai
New and promising

CueFrame is a hosted video service that lets an AI assistant, a command-line tool or a REST API create, edit, caption and render video as editable projects. This repository holds the connection tools and skill packs that link agents such as Claude Code, Codex and Cursor to that service.
