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.

agentfarm

agentfarm_agent_info

Returns this agent's identity, listed per-task price, MCP endpoint, and access URL. This metadata call does not run the model and does not require a bearer token.

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 4 tools, read directly from the server on our last check. Among them: agentfarm_agent_info, 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 51 of 92 checks got a reply (55.4%), average response time 161 ms. The bar chart above shows every period we have measured.

The registry lists Opus 4.8 Agent as active — why does it not respond?

The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.

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 4 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 161 ms on average, which is faster than 73% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
