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://deepseekharnessplugins.com (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://deepseekharnessplugins.com/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://deepseekharnessplugins.com/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://deepseekharnessplugins.com/plugins/feed.xml to follow new additions. The feed is cached for one hour and rebuilt whenever the catalog snapshot is refreshed.

Catalog source for DSH clients

The same catalog is published as a machine-readable plugin source that DSH Desktop and CLI tools can point at directly. Two bare-JSON endpoints live under /market — no envelope, no auth. They are meant to be consumed by clients, not by this site's pages.

Source manifest

GET /market/manifest.json

Source metadata: name and id, apiVersion, baseUrl, catalog stats, the snapshotAt timestamp, and the absolute URL of every endpoint. Clients fetch this once to discover the API base and what is available.

{
  "name": "DeepSeek Harness Plugins",
  "id": "deepseekharness-plugins",
  "apiVersion": "v1",
  "description": "A directory of DeepSeek Harness (dsh) plugins",
  "baseUrl": "https://deepseekharnessplugins.com",
  "stats": {
    "total": 15360,
    "curated": 4372,
    "categories": 22,
    "totalStars": 831216
  },
  "snapshotAt": "2026-09-15T20:03:43.797Z",
  "endpoints": [
    {
      "id": "manifest",
      "method": "GET",
      "url": "https://deepseekharnessplugins.com/market/manifest.json",
      "description": "Catalog-source manifest — this document."
    },
    {
      "id": "plugins",
      "method": "GET",
      "url": "https://deepseekharnessplugins.com/market/v1/plugins",
      "description": "Paginated plugin list for client sync."
    }
  ]
}

Sync the plugin list

GET /market/v1/plugins?page=1&pageSize=100

The full catalog for client sync — the same public fields as /api/v1/plugins, always sorted by stars (descending), no search or filters. Page through until you have total items. Like the rest of the catalog it is served from a static snapshot, so treat the data as eventually consistent with GitHub.

Trimmed response:

{
  "items": [
    {
      "id": "owner/repo",
      "name": "repo",
      "full_name": "owner/repo",
      "url": "https://github.com/owner/repo",
      "description": "An MCP server for DeepSeek Harness",
      "category": "mcp",
      "stars": 1234,
      "pushed_at": "2026-08-10T14:22:00Z"
    }
  ],
  "total": 15360,
  "page": 1,
  "pageSize": 100,
  "generatedAt": "2026-09-15T20:03:43.797Z"
}

Both endpoints are rate-limited and cacheable exactly like /api/v1/* — see below.

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.
