It provides three anonymous,\nread-only tools:\n\n- `resolve_server` resolves a title, package, endpoint, or name to a canonical server.\n- `find_servers` finds up to five servers using MCPLookup's normalized taxonomy.\n- `trust_lookup` returns the current Trust Index, verdict, evidence, and citation.\n\nThis package exists for MCP clients that require a local stdio command. It forwards MCP\nmessages to the canonical hosted server without implementing scoring, storing evidence,\nadding authentication, or changing tool results.\n\n## Connect\n\nConnect directly when your client supports remote Streamable HTTP:\n\n```text\nhttps://mcplookup.com/mcp\n```\n\nUse this package when your client requires a local stdio command:\n\nNode.js 20 or newer is required. No API key or environment variable is needed.\n\n```bash\nnpx -y @mcplookup/mcp\n```\n\nGeneric MCP client configuration:\n\n```json\n{\n  \"mcpServers\": {\n    \"mcplookup\": {\n      \"command\": \"npx\",\n      \"args\": [\"-y\", \"@mcplookup/mcp\"]\n    }\n  }\n}\n```\n\nPrefer a direct Streamable HTTP connection to `https://mcplookup.com/mcp` when your client\nsupports remote MCP servers. The package is a transport adapter, not a separate service.\n\n## MCP Registry\n\nMCPLookup is listed in the official MCP Registry as\n[`com.mcplookup/mcp`](https://registry.modelcontextprotocol.io/v0.1/servers?search=com.mcplookup/mcp).\nThe name is verified through DNS control of `mcplookup.com`.\n\nOne entry covers both connection paths, so a client installing from the Registry can use\nwhichever it supports:\n\n| Path | Declaration |\n| --- | --- |\n| Canonical remote | `streamable-http` → `https://mcplookup.com/mcp` |\n| Compatibility package | npm `@mcplookup/mcp`, `stdio` transport |\n\nThe entry declares no environment variables, headers, or credentials, matching the\nanonymous public interface. [`server.json`](./server.json) in this repository is the source\nof that metadata.\n\n## What stays remote\n\nThe wrapper contains no trust scores, evidence database, taxonomy, authentication system,\nor scoring logic. MCPLookup evaluates public evidence at the canonical service and returns\nthe same bounded, current-state response whether a client connects directly or through this\nstdio adapter.\n\nThe MIT license covers the plugin and wrapper software in this repository only. It does not\nlicense MCPLookup's hosted evidence database, assessments, verdicts, scores, classifications,\ntaxonomy, historical record, or scoring framework. Use of service data remains governed by\nthe [MCPLookup terms](https://mcplookup.com/legal/terms).\n\n## Data and security\n\nThe wrapper has no credentials and writes no local data. Requests are sent to MCPLookup's\nhosted endpoint, where bounded security and product telemetry are processed under the\n[MCPLookup privacy policy](https://mcplookup.com/legal/privacy). See the\n[MCP documentation](https://mcplookup.com/docs/mcp) for the public interface contract.\n\nReport security issues according to [SECURITY.md](./SECURITY.md). For product support,\nemail [hello@mcplookup.com](mailto:hello@mcplookup.com).\n\nBug reports and narrowly scoped compatibility improvements are welcome. See\n[CONTRIBUTING.md](./CONTRIBUTING.md) before opening a pull request.\n\n## Development\n\n```bash\nnpm test\nnpm pack --dry-run\n```\n\nThe package intentionally has zero runtime dependencies.\n\n## Marketplace package\n\nThis repository also contains the shared MCPLookup marketplace package:\n\n- `.claude-plugin/plugin.json` and `.mcp.json` package the remote server for Claude.\n- `.codex-plugin/plugin.json` packages the same remote server for ChatGPT and Codex.\n- `skills/verify-mcp-server/SKILL.md` adds the proactive pre-connect verification workflow.\n- `review/marketplace-cases.md` defines the positive, negative, and direct-connect release cases.\n\nThe skill improves orchestration but is not required for correct tool selection. Direct MCP,\nRegistry, npm-wrapper, and VS Code clients receive independently useful tool descriptions and\nserver instructions from the canonical hosted service.\n",
