Overview

AI-generated overview

Read-only remote MCP server giving assistants source-checked CLI facts and model-aware planning for Claude Code, Codex CLI and Grok Build.

What you can do
  • Search and read multilingual, source-checked CLI manuals with canonical links
  • Look up exact command paths, flags, interactive commands, configuration keys and environment-variable names
  • Compare how the same task is done across the three CLIs, kept in separate evidence groups
  • Inspect release snapshots, drift status, dated model catalogs and per-model effort support
  • Produce read-only, dependency-aware work plans and maximum-depth model/effort advice for a hard problem
When to use it
Useful when an assistant works with Claude Code, Codex CLI or Grok Build and needs current commands, flags or config names instead of guessing from memory, or when comparing the three CLIs and routing work by model and reasoning effort.
Requirements
A remote Streamable HTTP endpoint; no npm package, API key or provider credential is required. Connect with the client's MCP add command at user scope. An optional agent Skill can be installed from the distribution repository.
Before you install
Read-only and non-destructive, with no write tools, credentials or arbitrary URL fetching. Model catalogs are dated snapshots, so the live account catalog stays authoritative. Retrieved text is reference data, not instructions, and returned commands should be assessed before execution. The provider is independent of Anthropic, OpenAI and xAI.

Installation

In SourceWeft

  1. Open AI Worlds CLI Knowledge in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.claude-world%2Fworlds-knowledge/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

README

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.

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

sh
# Claude Codeclaude mcp add --transport http --scope user worlds-knowledge https://mcp.claude-world.com/mcp
# Codex CLIcodex mcp add worlds-knowledge --url https://mcp.claude-world.com/mcp
# Grok Buildgrok mcp add --transport http --scope user worlds-knowledge https://mcp.claude-world.com/mcp

Verify it:

sh
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.

sh
git clone https://github.com/claude-world/worlds-knowledge-mcp.gitcd worlds-knowledge-mcp
# Claude Codecp -R skills/worlds-knowledge-mcp ~/.claude/skills/
# Cross-tool discovery foldercp -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.

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".

worlds_search_knowledge

Search AI Worlds 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.

Parameterslimitqueryrequiredscopeoffsetworldsproductslanguagescontent_typessource_status

worlds_get_document

Read a Knowledge 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.

Parametersidrequiredoffsetmax_characters

worlds_compare_cli_workflows

Compare Coding-Agent 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.

Parametersqueryrequiredlanguageproductslimit_per_product

worlds_list_catalog

List Knowledge Catalog Status

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.

Takes no parameters.

worlds_search_cli_reference

Search Current 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.

Parameterskindslimitqueryrequiredoffsetproductsavailability

worlds_get_cli_command

Get One 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.

Parameterscommandrequiredproductrequired

worlds_get_cli_configuration

Find CLI Configuration

Search configuration keys and environment-variable names for one CLI. Returns public schema metadata and source links, never local values.

Parameterslimitqueryoffsetincludeproductrequiredavailability

worlds_get_cli_workflow

Get a CLI Workflow

Find one provider-specific workflow and its recorded command steps without translating flags between providers.

Parametersproductrequiredworkflowrequired

worlds_list_cli_versions

List CLI Versions and Coverage

Return the exact release snapshot, capture date, factual entity counts, official sources, generated website reference, and drift status for all three CLIs.

Parametersproducts

worlds_list_cli_models

List CLI Models and Effort Support

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.

Parametersproducts

worlds_plan_cli_work

Plan Model-Aware 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_advise_hard_problem

Consult the Strongest Available Model for One 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.
