Best for
  • Developers integrating DeepSeek V4.1 Flash into MCP clients
  • Chat or analysis workflows that combine text and image inputs
  • Users who want to self-host the server over stdio or a local streamable-http endpoint
  • Developers auditing NPM dependencies within AI workflows
  • Teams performing supply chain security assessments
  • Users of Claude Desktop, Cursor, or VS Code
Not for
  • Users who need image, video, or audio generation (this server is image understanding only)
  • Users looking for an officially DeepSeek-maintained server
  • Environments without a DeepSeek API key or network access to the DeepSeek API
  • 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
  • Requires the DEEPSEEK_API_KEY environment variable to make upstream DeepSeek API requests
  • The hosted endpoint at https://deepseek-mcp.ragweld.com/mcp requires Authorization: Bearer <token>
  • upload_file sends base64 image data that is stored by DeepSeek under your account
  • Local streamable-http mode binds a host and port and can enforce an origin allowlist via MCP_HTTP_ALLOWED_ORIGINS
  • 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
  • Data uploaded via upload_file is stored by DeepSeek under your account and persists unless you set an expiry or call delete_file; expiry must be between 3,600 and 2,592,000 seconds
  • Uploads are limited to 64 MiB and signature-checked before upload; upload_file does not accept local file paths and does not fetch arbitrary URLs on the server
  • Conversation memory lives in the process, is cleared on restart, and is bounded by CONVERSATION_MAX_MESSAGES
  • The hosted deployment has its own release cycle and may lag the npm/GitHub release, so inspect tools/list before relying on a new tool
  • This server is community-maintained and is not an official DeepSeek release
  • 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
