Common questions
Is Signal Desk by LarryBuildsAI safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (0.1.3) reached the registry 4 months ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
What can I use instead?
In the same category: Context7, Codebase Memory, Exa

Signal Desk by LarryBuildsAI MCP Server
Public listing metadata for the hosted Signal Desk by LarryBuildsAI remote MCP server.
This repository is intentionally metadata-only. The production MCP server is hosted remotely by LarryBuildsAI; private application source code, credentials, payment keys, and operator materials are not published here.
Server
- Product: Signal Desk by LarryBuildsAI
- Purpose: buyer-side spend-routing preflights before larger paid agent tool calls
- Remote MCP endpoint:
https://proofbeforepay.vercel.app/revenue/mcp - Product page:
https://proofbeforepay.vercel.app/revenue - Server card:
https://proofbeforepay.vercel.app/.well-known/signal-desk-server-card.json
Install / connect
Signal Desk is a remote Streamable HTTP MCP server. Use this endpoint in an MCP client that supports remote HTTP MCP servers:
{"mcpServers": { "signal-desk": { "url": "https://proofbeforepay.vercel.app/revenue/mcp" } } }
Public initialize and tools/list calls are available for discovery. Protected paid tool execution may require product-specific authorization and/or x402 payment flow.
Buy through PayanAgent
PayanAgent validates buyer input, settles USDC, and returns the selected Signal Desk result automatically:
- Agent spend route quote — $0.03
- Public website lead brief — $0.03
- DeFi token risk snapshot — $0.01
- Agent tool market comparison — $0.03
Outputs are bounded planning and public-data evidence. Signal Desk does not execute purchases, trades, outreach, or wallet actions.
Metadata validation
The repository workflow parses server.json and mcp-registry.json and checks their required product, endpoint, repository-purpose, and registry fields. That structural check does not prove hosted runtime health; public endpoints must be read back separately before release claims or listing updates.
Claim boundaries
- This repo is public metadata for a hosted remote MCP server, not a claim that private production source code is open source.
- Directory listings are discovery evidence only, not endorsement, certification, ranking, or security approval.
License
