Tools have disappeared from this server

A tool that vanishes takes a piece of your agent with it, and the change arrives silently. Watch this server and every such change lands in your inbox.

Lazareus — questions

Answers built from our own checks of this server.

What can Lazareus do?

It exposes 8 tools, read directly from the server on our last check. Among them: get_network_health_base, get_network_health_ethereum, get_network_health_solana, get_recommended_priority_fee_base, get_recommended_priority_fee_ethereum, get_recommended_priority_fee_solana and 2 more. 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 →

What is Lazareus mostly used for?

Its tools cluster around network and recommended. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is Lazareus working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 221 ms. The bar chart above shows every period we have measured.

Did Lazareus ever remove tools?

Yes. is_network_degraded, is_validator_delinquent, get_network_health, get_recommended_priority_fee are no longer exposed — we recorded the date each one disappeared. A tool vanishing usually means a breaking change for anything that depended on it.

How do I connect Lazareus?

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

Does Lazareus need an API key?

No. Lazareus completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 8 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Lazareus?

It answers our handshake in 221 ms on average, which is faster than 69% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
