Common questions
Is Wealth Engine — Economic Opportunity Intelligence 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 (0.6.0) reached the registry 2 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?

Wealth Engine
Economic opportunity intelligence for AI agents and digital business experiments.
Wealth Engine turns public market evidence into machine-consumable economic hypotheses, ranked experiments, pricing benchmarks, and explicit kill criteria. It is not a generic MCP directory and it does not claim to predict revenue. Its purpose is to shorten the path from observable market evidence to a falsifiable economic experiment.

MCP tools
economic_opportunities
Read-only. Returns ranked economic opportunities. Each opportunity contains the thesis, evidence, monetization paths, scoring dimensions, next experiment, success condition, and kill condition.
Use it when an agent needs to decide what economic experiment to run next, not merely which software tool exists.
voice_margin_index
Read-only. Returns structured AI-voice retail pricing, revenue-per-minute calculations, gross-margin cost ceilings, source URLs, and row-level verification metadata.
No account. No API key. No signup. Both tools are currently free while demand and willingness to pay are validated.
Example prompts
Find the highest-ranked economic opportunity in Wealth Engine and explain the smallest experiment that could falsify it.Which current opportunity has the best combination of speed, margin potential and automation? Use the evidence, not intuition.I want a business experiment that can reach paid-demand evidence before more infrastructure is built. Use Wealth Engine to choose one.Compare current AI voice providers using customer-facing pricing and show where a commercial service could or could not preserve gross margin.What revenue per minute is implied by current AI voice plans, and what underlying cost ceiling would preserve a 70% gross margin?
Evidence policy
Wealth Engine distinguishes observations from hypotheses.
Pricing rows expose a source URL, verifiedAt, and verificationStatus. Required source pages are checked automatically for reachability. Reachability proves that a source is accessible; it does not prove that the price has not changed. Pricing data is therefore separately verified and timestamped.
Opportunity scores are prioritization heuristics, not forecasts. Every opportunity must expose a concrete experiment and a kill condition so weak theses can be discarded quickly.
Privacy
Wealth Engine does not require authentication and does not intentionally collect prompts, conversation history, uploaded files, personal identifiers, or request bodies. It records aggregate operational counters used to measure endpoint usage and paid-intent clicks.
Support and troubleshooting
Report data-quality, compatibility, product, purchasing-interest, or security issues using this repository's GitHub issue tracker.
The MCP endpoint uses Streamable HTTP over JSON-RPC POST. A browser GET request to /mcp may return 404 and is not a valid protocol test. Use an MCP client or MCP Inspector to initialize the server and call tools/list.
Direction
market signals → economic hypotheses → ranked experiment → real demand evidence → monetization → keep/kill/scaleWealth Engine should consume directories, APIs, marketplaces and public market signals rather than duplicate them. The target is increasing autonomous economic evidence and ultimately net capital generated — not feature count.
