Does the DeepSeek chat app support MCP?

Not that we know of. DeepSeek's agent with MCP support is DeepSeek Harness, an open-source agent you run on your own machine or as a desktop app.

How do I connect DeepSeek Harness to OmniSocials?

Add the dsh-mcp-client plugin to ~/.dsh/cordis.patch.yml with the URL https://mcp.omnisocials.com and your OmniSocials API key as an Authorization: Bearer header, then start a new session.

Can I use DeepSeek models in Claude Code instead?

Yes. DeepSeek's API is Anthropic-compatible. Point Claude Code at api.deepseek.com/anthropic with your DeepSeek key, then add OmniSocials with claude mcp add. See the Claude Code integration page.

Does the OmniSocials skill work in DeepSeek Harness?

Yes. Harness reads skills from .agents/skills and ~/.dsh/skills, so npx skills add omnisocials/agent-skills works.

DeepSeek Harness is free and open source. You pay DeepSeek for API usage. OmniSocials starts with a 14-day free trial.

Which platforms are supported?

Instagram, Facebook, LinkedIn, YouTube, TikTok, X, Pinterest, Threads, Bluesky, Mastodon, and Google Business, including Stories and Reels where available.
