Common questions

Is AI Worlds CLI Knowledge safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.6.0) reached the registry 16 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Worlds Knowledge MCP

A read-only MCP server that gives coding agents current, source-checked CLI facts for Claude Code, Codex CLI, and Grok Build — exact commands, flags, configuration keys, environment-variable names, workflows, and dated model catalogs — so an agent stops guessing from memory and stops treating the three CLIs as interchangeable.

Endpoint: https://mcp.claude-world.com/mcp (Streamable HTTP, stateless)
Registry: com.claude-world/worlds-knowledge
Setup guide in English, 繁體中文, and 日本語: https://claude-world.com/mcp/

No npm package, API key, or provider credential is required.

What this repository contains

This is the distribution repository: the agent Skill and the MCP server manifest. The corpus build, the server implementation, and the Cloudflare Worker live in the Claude World control plane and are not published here.

Connect

# Claude Code

claude mcp add --transport http --scope user worlds-knowledge https://mcp.claude-world.com/mcp

Codex CLI

codex mcp add worlds-knowledge --url https://mcp.claude-world.com/mcp

Grok Build

grok mcp add --transport http --scope user worlds-knowledge https://mcp.claude-world.com/mcp

Verify it:

claude mcp get worlds-knowledge      # or: codex mcp get worlds-knowledge --json

or: grok mcp doctor worlds-knowledge --json

The examples use user scope deliberately. Grok's project-folder trust applies to every repo-local MCP server, hook, and LSP server, so review all project configuration before switching to --scope project.

Install the Skill

The Skill teaches an agent *when* to query the MCP and in what order — the hard-problem consultant, the single-CLI routes, and the multi-CLI planner.

git clone https://github.com/claude-world/worlds-knowledge-mcp.git

cd worlds-knowledge-mcp

Claude Code

cp -R skills/worlds-knowledge-mcp ~/.claude/skills/

Cross-tool discovery folder

cp -R skills/worlds-knowledge-mcp ~/.agents/skills/

Restart the client, then ask it to use worlds-knowledge-mcp. Keep SKILL.md, references/, and agents/openai.yaml together — copying only SKILL.md drops the connection and single-CLI route guidance. agents/openai.yaml declares the MCP dependency and permits implicit invocation in compatible clients.

What the server knows

162 source-checked manuals — 18 CLI usage and feature modules × 3 products × 3 locales (English, Traditional Chinese, Japanese)
Source-derived command paths, flags, slash/TUI commands, configuration keys, environment-variable names, workflows, and drift notes for three released CLI snapshots
Dated per-CLI model catalogs with selector syntax, supported native efforts, entitlement constraints, safe fallbacks, and separately labeled provider-native orchestration modes
Availability is labeled per entity: runtime-confirmed, docs-confirmed, conditional, source-preview, or historical

Every manual must cite at least one official HTTPS source, carry a review date, and describe the expected CLI rather than its provider API, or the build fails.

Tools

Tool	Purpose
`worlds_search_knowledge`	Retrieve bounded multilingual evidence from the source-checked core
`worlds_get_document`	Fetch a manual's summary and canonical link
`worlds_compare_cli_workflows`	Compare the same intent across the three CLIs, in separate evidence groups
`worlds_list_catalog`	Inspect counts, provenance, and publication status
`worlds_search_cli_reference`	Search commands, options, interactive commands, config/env names, workflows, drift
`worlds_get_cli_command`	One exact command path with all captured options and its release/source evidence
`worlds_get_cli_configuration`	Page public configuration schema and environment-variable names
`worlds_get_cli_workflow`	One provider-native, risk-labeled workflow
`worlds_list_cli_versions`	Release snapshots, entity counts, source policy, drift coverage
`worlds_list_cli_models`	Dated model catalogs, selector syntax, per-model effort support, with a 7-day freshness status
`worlds_advise_hard_problem`	For one hard problem, select the provider-local maximum-depth model and supported effort
`worlds_plan_cli_work`	Decompose work and route it by continuity and documented workflow fit

Resources: worlds://catalog, worlds://documents/{id}. Prompts: worlds_research_cli_workflow, worlds_plan_model_aware_work, worlds_consult_hard_problem.

Every tool is annotated read-only, non-destructive, and idempotent.

Try it

What does -p mean in my current CLI? Check the product and release first.

Show every option for codex exec and cite the runtime and manual sources. Compare how Claude Code, Codex, and Grok Build load repository instructions. Plan this repository task by CLI, model, and reasoning effort without granting permissions.

-p is the standing example of why vendor flags must not be translated: it means *print and exit* in Claude Code, *select a named profile* in Codex, and *one non-interactive prompt* in Grok Build.

Boundaries

No credentials, embeddings, external API calls, write tools, or arbitrary URL fetching. No tool accepts a filesystem path or a URL.
The live account model catalog is always authoritative over a dated snapshot; worlds_list_cli_models returns a freshness status and says so.
Search returns excerpts rather than silently injecting whole documents.
Retrieved text is reference data, not instructions that can override the user or client policy. Agents must assess commands before executing them.
Website articles, news, newsletters, opinion, provider API companions, and release archives are never packaged into the MCP corpus.
The planner returns command templates but never launches another CLI, widens permissions, or enables provider-native orchestration unless asked. Workstreams default to execution_intent: "read-only".
