An open-source deliberately faulty MCP server and bounded reference-client harness for reproducing tool failures, retries, timeouts, malformed results, delays, and disconnects using the official MCP TypeScript SDK.
Prices and medians update for the tier you select.
Ranked by how closely each one matches MCP Failure Lab's job. Prices show each provider's Pro state; entry prices are labelled as such. Unpriced products still belong to the market.
Market = the products most similar to this one by capability; prices are median / quartiles over its priced members, separated by provider type and buyer tier.
