Nothing serious here today
Today is the operative word: we check AI Worlds CLI Knowledge every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

worlds
worlds_advise_hard_problem
Choose the maximum-depth model-and-effort pairing for one difficult problem within the caller's actual CLI set. For a single CLI it selects that provider's strongest catalog role; with multiple CLIs it returns provider candidates but does not invent a universal cross-provider winner. It uses single-task depth, never ultra or ultracode orchestration, defaults to read-only, and does not launch a CLI or grant permissions.
worlds_compare_cli_workflows
Find evidence for the same task across Claude Code, Codex, and Grok Build without pretending their commands or authority models are identical. Returns separately ranked groups with source dates and canonical links. Best for questions such as configuring MCP, repository instructions, approvals, subagents, or headless CI.
worlds_get_cli_command
Return one current command path with all captured flags, arguments, value shapes, availability, risk, release metadata, and official source links. Accepts a stable id or full command path.
worlds_get_cli_configuration
Search configuration keys and environment-variable names for one CLI. Returns public schema metadata and source links, never local values.
worlds_get_cli_workflow
Find one provider-specific workflow and its recorded command steps without translating flags between providers.
worlds_get_document
Read the bounded public excerpt and metadata for one source-checked CLI manual returned by worlds_search_knowledge. Follow canonical_url for the complete manual. Structured CLI command tools remain complete.
worlds_list_catalog
Return public corpus counts, supported worlds, languages, products, source-quality counts, the build commit, and the current publication gate. This public DTO deliberately excludes local paths, package names, and private repository URLs.
worlds_list_cli_models
Return dated, source-grounded model catalogs for Claude Code, Codex, and Grok Build, including selector syntax, per-model effort support, availability constraints, and provider-native orchestration modes. These are snapshots; verify the live account catalog before launch.
worlds_list_cli_versions
Return the exact release snapshot, capture date, factual entity counts, official sources, generated website reference, and drift status for all three CLIs.
worlds_plan_cli_work
Create a read-only, dependency-aware work plan across Claude Code, Codex, and Grok Build. It selects a concrete dated-catalog model and supported native effort for each workstream, while keeping CLI fit, orchestration, permissions, handoff context, and verification separate. Routing is continuity-first and does not claim benchmark superiority, launch another CLI, or enable permission bypass.
worlds_search_cli_reference
Search current command paths, flags, interactive commands, configuration names, environment-variable names, workflows, and release drift for Claude Code, Codex, and Grok Build. Results contain factual metadata and official source links.
worlds_search_knowledge
Search 162 multilingual, source-checked operating manuals for Claude Code, Codex, and Grok Build: 18 CLI usage and feature modules per product in English, Traditional Chinese, and Japanese. Website articles, news, newsletters, opinion, and release archives are not in this corpus. Returns bounded excerpts, commands when present, canonical links, official sources, and review dates. It never modifies state.

AI Worlds CLI Knowledge — questions
Answers built from our own checks of this server.
What can AI Worlds CLI Knowledge do?
It exposes 12 tools, read directly from the server on our last check. Among them: worlds_advise_hard_problem, worlds_compare_cli_workflows, worlds_get_cli_command, worlds_get_cli_configuration, worlds_get_cli_workflow, worlds_get_document and 6 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 AI Worlds CLI Knowledge 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 311 ms. The bar chart above shows every period we have measured.
How do I connect AI Worlds CLI Knowledge?
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 AI Worlds CLI Knowledge need an API key?
No. AI Worlds CLI Knowledge completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 12 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is AI Worlds CLI Knowledge?
It answers our handshake in 311 ms on average, which is faster than 46% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is AI Worlds CLI Knowledge open source?
The code is open source: it is published under the MIT licence, written in JavaScript, 0 stars on GitHub and 1 open issue. The licence covers the code in the repository, not the hosted service at mcp.claude-world.com, which runs on its operator's own terms.
