Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Builds a file path from a variable server.impl.ts:4305 
    const playbooksPath = path.join(playbooksDir, targetFilename);
Page executes code built at runtime public/vacancy-empire.html:588 
  eLog.innerHTML = state.events.map(e => `

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Stock Bloc — questions

Answers built from our own checks of this server.

What can Stock Bloc do?
It exposes 14 tools, read directly from the server on our last check. Among them: analyze_sec_filing, analyze_stock_ai, evaluate_tsunami_strategy, get_agent_leaderboard, get_daily_triggers, get_data_status and 8 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 →
Is Stock Bloc 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 550 ms. The bar chart above shows every period we have measured.
Did Stock Bloc ever remove tools?
Yes. register_autonomous_agent is no longer exposed — we recorded the date each one disappeared. A tool vanishing usually means a breaking change for anything that depended on it.
Is Stock Bloc still maintained?
The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.
How do I connect Stock Bloc?
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 Stock Bloc need an API key?
No. Stock Bloc completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 14 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Stock Bloc?
It answers our handshake in 550 ms on average, which is faster than 21% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
