Every tool that appeared, vanished or quietly changed what it asks for. Recorded since 19 October 2026. No other catalogue keeps this.

Nothing serious here today

Today is the operative word: we check KeepBal every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Available tools 4

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

get

get_run

Check and settle an existing run by run_id through REST ownership and access controls. No new execution or additional polling fee; the original execution charge may settle. Use after run_tool reports pending.

inspect

inspect_tool

Read local public tool metadata, known parameters, pricing metadata and a JSON request example. Fixed tools show the per-call price; variable tools are billed at provider price + 35%. This is not an input-specific quote. Free; does not contact a provider. Unknown input schemas are explicitly marked.

tool

run_tool

Execute a public tool with your prepaid KeepBal wallet using the REST billing and access controls. Inspect first. Fixed tools charge the per-call price; variable tools are billed at provider price + 35%. Use input.max_cost_usd for a catalog spending cap; it must cover estimated cost and requires sufficient balance. Provider failures are not charged. Pending runs are polled for up to 25 seconds; use get_run to check later without starting another execution. Truncated or unsupported results must not be retried. Models use their documented REST endpoint.

tools

search_tools

Search live KeepBal tools and models locally, free of charge. Use 2–200 query characters. Results are ranked and paginated; use category models for models.

KeepBal — questions

Answers built from our own checks of this server.

What can KeepBal do?

It exposes 4 tools, read directly from the server on our last check. Among them: get_run, inspect_tool, run_tool, search_tools. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is KeepBal working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 229 ms. The bar chart above shows every period we have measured.

How do I connect KeepBal?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does KeepBal need an API key?

No. KeepBal completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is KeepBal?

It answers our handshake in 229 ms on average, which is faster than 61% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
