install

Requirements:

Claude Code

From shell:

claude mcp add claude-oracle-mcp -- npx claude-oracle-mcp

From inside Claude (restart required):

Add this to our global mcp config: npx claude-oracle-mcp

Install this mcp: https://github.com/Vvkmnn/claude-oracle-mcp

From any manually configurable mcp.json: (Cursor, Windsurf, etc.)

{
  "mcpServers": {
    "claude-oracle-mcp": {
      "command": "npx",
      "args": ["claude-oracle-mcp"],
      "env": {
        "SKILLSMP_API_KEY": "optional-for-semantic-search",
        "GITHUB_TOKEN": "optional-for-higher-rate-limits"
      }
    }
  }
}

There is no npm install required -- no external dependencies or local databases, only search algorithms.

However, if npx resolves the wrong package, you can force resolution with:

npm install -g claude-oracle-mcp

skill

Optionally, install the skill to teach Claude when to proactively use oracle:

npx skills add Vvkmnn/claude-oracle-mcp --skill claude-oracle --global
# Optional: add --yes to skip interactive prompt and install to all agents

This makes Claude automatically search for relevant tools before planning, when encountering errors, or at session start. The MCP works without the skill, but the skill improves discoverability.

plugin

For automated tool discovery with hooks, install from the claude-emporium marketplace:

/plugin marketplace add Vvkmnn/claude-emporium
/plugin install claude-oracle@claude-emporium

The claude-oracle plugin provides:

Hooks (targeted, fires before external searches):

• Before WebSearch/WebFetch → Check oracle for existing tools first
• Before EnterPlanMode → Search for relevant plugins/skills

Command: /oracle-search <query>

Requires the MCP server installed first. See the emporium for other Claude Code plugins and MCPs.

features

Core features:

• 17 registries + GitHub search + web search: Smithery, npm, Glama.ai, GitHub, awesome lists + more
• 15,000+ resources: Skills, plugins, and MCP servers in one search
• Parallel fetching: All sources searched simultaneously (~3 seconds)
• Smart caching: In-memory TTL cache (6-24 hour expiry)
• Keyword scoring: Weighted matching (exact > starts with > contains)
• Quality signals: Stars, verified badges, quality scores boost ranking
• Beautiful formatting: Bordered output with 🔮 identifier

Data sources (zero-config, 16/17 registries):

Source	Type	Count	Method
Smithery Registry	MCP	500	REST API (5 pages)
Playbooks	MCP	1,000+	XML Sitemaps
Official MCP Registry	MCP	248	REST API (3 iterations)
npm Registry	MCP/Plugin	250	Search API (1 page)
Glama.ai	MCP	662	RSS Feed
wong2/awesome-mcp-servers	MCP	200+	GitHub Markdown
punkpeye/awesome-mcp-servers	MCP	400+	GitHub Markdown
collabnix/awesome-mcp-lists	MCP	100+	GitHub Markdown
jmanhype/awesome-claude-code	Plugin/Skill	50+	GitHub Markdown
hesreallyhim/awesome-claude-code	Skill	200+	GitHub Markdown
awesome-agent-skills	Skill	339	GitHub Markdown
claude-code-plugins-plus	Plugin	258	Marketplace JSON
claude-plugins-official	Plugin	45	Marketplace JSON
superpowers-marketplace	Plugin	-	Marketplace JSON

Query-based (searched per query, zero-config):

Source	Type	Count	Method
GitHub (search)	MCP/Plugin	~20	REST API (per query)
Web (search)	MCP/Plugin	~10	DuckDuckGo Lite (per query)

Optional (requires API key):

• SkillsMP: 25,000+ skills with semantic search (get key)
• GITHUB_TOKEN: Higher GitHub API rate limits (10 → 30 req/min)

Note: Pagination is limited for faster responses (~3s). Full datasets available through caching on subsequent searches.

Design principles:

• Aggregated search -- single query searches 17 registries + GitHub + web simultaneously
• Zero-config -- 18/19 sources work without API keys (GITHUB_TOKEN optional for rate limits)
• Deduplication -- cross-source result merging by name similarity
• Relevance scoring -- weighted name match, description match, and popularity
• Offline fallback -- graceful degradation when sources are unreachable

alternatives

Every MCP discovery tool either searches a single registry or requires separate accounts per source. Oracle aggregates 19 sources in one command.

Feature	oracle	1mcpserver	Single registry
Resource types	MCP + plugins + skills	MCP servers only	Usually one type
Sources	19 (registries + awesome lists + GitHub + web)	Registry searches	One source at a time
Skills/plugins	Yes (339 skills, 303 plugins)	No	Usually no
Setup	One MCP, one command	One MCP, one command	Separate account/API per registry
Cross-source	Deduplicated, ranked results	Per-registry	Manual comparison
Caching	In-memory TTL (6-24h)	Per-request	Varies
Install commands	Included in results	Included in results	Varies

1mcpserver -- MCP server discovery from multiple registries. Searches MCP servers only -- no plugins, no skills. Per-registry results without cross-source dedup or ranking. No caching between requests.

Smithery, Glama, SkillsMP -- Individual registries, each searchable independently. Requires separate accounts or API access per registry. Each covers a subset of the ecosystem -- no single source has everything. Manual comparison across registries to find the best option. Oracle aggregates all of these (and 16 more sources) with deduplicated, ranked results in one query.

development

git clone https://github.com/Vvkmnn/claude-oracle-mcp && cd claude-oracle-mcp
npm install && npm run build
npm test

Package requirements:

• Node.js: >=20.0.0 (ES modules)
• Runtime: @modelcontextprotocol/sdk, fast-xml-parser
• Zero external databases -- works with npx

Development workflow:

npm run build          # TypeScript compilation with executable permissions
npm run dev            # Watch mode with tsc --watch
npm run start          # Run the MCP server directly
npm run lint           # ESLint code quality checks
npm run lint:fix       # Auto-fix linting issues
npm run format         # Prettier formatting (src/)
npm run format:check   # Check formatting without changes
npm run typecheck      # TypeScript validation without emit
npm run test           # Lint + type check
npm run prepublishOnly # Pre-publish validation (build + lint + format:check)

Git hooks (via Husky):

• pre-commit: Auto-formats staged .ts files with Prettier and ESLint

Contributing:

• Fork the repository and create feature branches
• Test with multiple data sources before submitting PRs
• Follow TypeScript strict mode and MCP protocol standards

Learn from examples:

• Official MCP servers for reference implementations
• TypeScript SDK for best practices
• Creating Node.js modules for npm package development
