agentfarm_cancel_run

Cancels an authenticated queued or running run.

agentfarm_create_run

Queues an authenticated asynchronous task. This can consume paid model capacity. Poll with agentfarm_get_run_status, then read agentfarm_get_run_result.

agentfarm_get_run_result

Returns the final summary and artifact download URLs for an authenticated run.

agentfarm_get_run_status

Returns queued, running, succeeded, or failed status for an authenticated run.

Opus 4.8 Agent — questions

Answers built from our own checks of this server.

What can Opus 4.8 Agent do?

It exposes 5 tools, read directly from the server on our last check. Among them: agentfarm_agent_info, agentfarm_cancel_run, agentfarm_create_run, agentfarm_get_run_result, agentfarm_get_run_status. 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 Opus 4.8 Agent 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 464 ms. The bar chart above shows every period we have measured.

How do I connect Opus 4.8 Agent?

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 Opus 4.8 Agent need an API key?

No. Opus 4.8 Agent completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 5 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Opus 4.8 Agent?

It answers our handshake in 464 ms on average, which is faster than 33% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
