Best for
  • Developers seeking a customizable, open-source MCP client framework
  • AI app builders who want to leverage tools from multiple MCP servers
  • Projects needing modern React UI components and streaming responses
  • Developers auditing NPM dependencies within AI workflows
  • Teams performing supply chain security assessments
  • Users of Claude Desktop, Cursor, or VS Code
Not for
  • Users needing a production-grade, fully hosted MCP client solution
  • Users who need to run MCP servers locally via stdio (client supports only HTTP and SSE)
  • Non-technical users as it requires development deployment
  • Projects outside the NPM ecosystem (e.g., pure Python/Go)
  • Environments without network access to deps.dev, OSV.dev, and the npm registry
  • Scenarios requiring maintenance by an official upstream vendor
Required permissions
  • Network access: Connects to MCP servers via HTTP or SSE
  • System access: Requires basic system resources to run as a Next.js app
  • Users typically need to configure API keys for AI providers
  • Network access to the NPM registry and external services (deps.dev, OSV.dev, OpenSSF, npms.io, GitHub)
  • Read access to workspace lockfiles (pnpm-lock.yaml, package-lock., yarn.lock) for cache invalidation
Risks and side effects
  • Connecting to untrusted MCP servers may introduce malicious tools
  • Stored API keys may be at risk if environment is insecure
  • As an open-source project, there may be unpatched vulnerabilities
  • Third-party READMEs and changelogs are untrusted external content; they are wrapped in tags with _meta flags but should still be handled cautiously
  • Depends on availability and accuracy of external services
  • Batch requests are capped at 25 packages to prevent registry enumeration; larger sets require batching
  • Third-party open source project, not officially maintained by NPM or Anthropic
