DeepSeek Harness Plugins API — Free JSON API & RSS Feed

The DeepSeek Harness plugins catalog is available as a public, read-only JSON API and an RSS feed — no account, no API key, no sign-up. Use it to build plugin pickers, badge services, trend dashboards, or your own directory on top of our data.

Base URL: https://deepseekharness.dev (same host as this site)

All responses use the site's standard envelope:

{ "code": 0, "message": "ok", "data": {} }

code: 0 means success; anything else is an error with a human-readable message.

List plugins

GET /api/v1/plugins

Query parameters (all optional):

Example:

curl "https://deepseekharness.dev/api/v1/plugins?category=mcp&sort=stars&pageSize=5"

Trimmed response:

{
  "code": 0,
  "message": "ok",
  "data": {
    "items": [
      {
        "id": "owner/repo",
        "name": "repo",
        "full_name": "owner/repo",
        "url": "https://github.com/owner/repo",
        "homepage": null,
        "description": "An MCP server for DeepSeek Harness",
        "description_zh": null,
        "category": "mcp",
        "categories": ["mcp"],
        "stars": 1234,
        "forks": 56,
        "language": "TypeScript",
        "license": "MIT",
        "archived": false,
        "created_at": "2025-11-02T08:15:00Z",
        "pushed_at": "2026-08-10T14:22:00Z",
        "topics": ["dsh-plugin", "mcp"]
      }
    ],
    "total": 42,
    "page": 1,
    "pageSize": 5,
    "generatedAt": "2026-08-18T06:00:00.000Z"
  }
}

generatedAt is the timestamp of the catalog snapshot the response was served from — use it to decide whether your cache is stale.

Get a single plugin

GET /api/v1/plugins/:owner/:repo

Returns one plugin with the same field set as the list endpoint, or a 404 envelope when the repo is not in the catalog.

curl "https://deepseekharness.dev/api/v1/plugins/cccakeee/awesome-dsh-plugins"

{
  "code": 0,
  "message": "ok",
  "data": {
    "plugin": {
      "id": "cccakeee/awesome-dsh-plugins",
      "name": "awesome-dsh-plugins"
    },
    "generatedAt": "2026-08-18T06:00:00.000Z"
  }
}

RSS feed

The 50 newest plugins in the catalog, as an RSS 2.0 feed:

GET /plugins/feed.xml

Point any feed reader at https://deepseekharness.dev/plugins/feed.xml to follow new additions. The feed is cached for one hour and rebuilt whenever the catalog snapshot is refreshed.

Rate limits & fair use

• Each API endpoint allows one request per 2 seconds per IP. Exceeding it returns 429 with a Retry-After header.
• Responses are cacheable (Cache-Control: public, max-age=300) — please cache instead of polling.
• The catalog is a static snapshot refreshed regularly; treat the data as eventually consistent with GitHub.

• Browse the human-facing directory at Plugins — every list view there is backed by the same catalog service.
