Spring Prompt
The best prompt and the best model for the job, tested and improved by your coding agent.
What it does
Spring Prompt is an MCP server, a connector that lets an AI assistant use it as a tool. It is hosted: an assistant connects to it over the internet, nothing to install.
No capability identified yet from its description.
Facts come from the Official MCP Registry, as declared by the publisher. Capabilities are matched automatically (low confidence). None of this is a test of the tool.

9 tools offered to AI assistants
test_prompt· Start a test of one prompt across several models. Spends credit, never more than max_spend_usd by estimate. Returns at once with a test_id: call get_test for the results. Cases and checks are drafted if left out.get_test· A test's status and, when done, what it found: the best model, each model's pass rate and cost, and sample failures.improve_prompt· Rewrite a finished test's prompt from its failures and ratings, then test the new version on the same cases, checks and models. Spends credit.list_tests· This account's recent prompt tests.list_models· Models a test can use, with prices, and the credit left on this account.rating_link· A link that lets anyone rate a test's answers on their phone, with no account and the models hidden. Send it to whoever knows what good looks like. Anyone with the link can read those answers and inputs, so ask before sharing.train_judge· Train a judge on a test's ratings. It's tested on answers it hasn't seen, and only kept if it beats always giving the commoner verdict. Spends a little credit.list_judges· This account's trained judges, and how often each agreed with its rater.score_answers· Score up to 50 answers with a trained judge: how likely the person it learned from is to call each one good, from 0 to 1. Spends a little credit.
What "online" means: the server answered an MCP connection at the time of the check. It is not a guarantee of security, quality or continuous uptime. How we test: we open an MCP session and ask for the tool list, as an AI assistant would. We never run a tool and never send a key. Checked every few days. Method
Is this your server? Monitoring Pro: a check every 30 minutes and an email within the hour when it stops answering. Launch offer: $39.99 once, for life.
