Amplitude offers progressive discovery as an option; Keploy makes it the only mode. The tool list is three meta-tools plus onboarding, and everything real is found by keyword and called through invoke_tool. That keeps the standing cost near zero, at the price of a discovery round trip and of pages like this being unable to tell you what the catalogue contains. The onboarding tools answering unauthenticated is a nice touch — the agent can walk you through setup before you have a key.
Keploy's endpoint for generating and running API tests from OpenAPI specs, curl commands, Postman collections or real traffic. It answered our probe as keploy-atg 1.0.0, and what it listed was not the tool catalogue but the means to find it.
- search_tools — discover tool names by keyword; most Keploy tools are hidden from the default list
- get_tool_schema — the exact schema for a tool you already know by name
- invoke_tool — run any Keploy tool by name with arguments
- get_auth_status — whether the session has a valid-looking key attached
- get_setup_instructions and devloop_setup_instructions — connection guides for Cursor, Windsurf and VS Code
- devloop_begin_oauth_install — a playbook the agent walks through with you
A bearer key from Keploy's settings, visible once when created. The onboarding tools answer without it, which is how the install flow works.
