## Introduction

DeepSeek Harness (dsh) is an open-source agent runtime from DeepSeek AI, and every part of it is a plugin, so you can swap out the model adapter, the tool registry, or the agent loop. It runs on the Cordis framework and comes with a local Web UI, a headless CLI runner, and a Python SDK. You can point it at DeepSeek V4-Pro and V4-Flash, or at Anthropic, OpenAI, and other OpenAI-compatible providers. It is MIT licensed and still in developer preview.
This guide shows how to connect your Search api account to DeepSeek Harness, and you can do it with either the Composio Connect CLI or the Composio Connect MCP. The dsh-base bundle gives shell execution as a first-class tool, so the CLI is the easiest path for personal use. It is quick to set up and needs no server config, and the MCP path works well too, since the harness comes with a built-in MCP client.

## TL;DR

### What is Composio Connect?
Composio Connect lets anyone plug 1,000+ applications directly into their agent harness, including DeepSeek Harness, through a single hosted MCP endpoint. Each task runs as a session, a scoped runtime that ties together the user, the available toolkits, authentication, and execution state. It can:
- Discover and load tools on-demand. A small set of meta tools lets the agent search for the right tool at runtime, so you never load hundreds of tool definitions into context.
- Chain tools in a sandboxed remote workbench. Multi-step workflows run server-side, passing outputs between tools and working with files in the session's sandbox, so long chains finish without a lot of back-and-forth with the LLM.
- Manage authentication end-to-end. Managed OAuth, per-user connected accounts, and account isolation are all handled for you, so you never wire up auth yourself.

## Connect Search api to DeepSeek Harness

### Prerequisites: Install DeepSeek Harness
DeepSeek Harness needs Node.js (20 or 22) and pnpm. Build it from source. This is also what the MCP path in Option 2 requires, since the built-in MCP client resolves its dependencies from the checkout:

```bash
git clone https://github.com/deepseek-ai/deepseek-harness.git
cd deepseek-harness
pnpm install
pnpm run build
pnpm dsh web
```

## What is the Search api MCP server, and what's possible with it?

The Search api MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Search api account. It provides structured and secure access so your agent can perform Search api operations on your behalf.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `SEARCH_API_GET_ACCOUNT_INFO` | Get Account Info | Tool to retrieve account usage statistics including monthly usage, remaining credits, hourly limits, and subscription period information. Use when you need to check current account status or usage limits. |
| `SEARCH_API_GET_CACHED_SEARCH_BY_ID` | Get Cached Search by ID | Tool to retrieve cached search results by search ID in JSON format. Use when you need to access previously executed search results without re-running the query. The search ID is found in the search_metadata.id or search_metadata.json_url field from initial search responses. Cached results are available for 90 days. |
| `SEARCH_API_GET_CACHED_SEARCH_HTML_BY_ID` | Get Cached Search HTML by ID | Tool to retrieve cached search results by search ID in HTML format. Use when you need to access the raw HTML snapshot of a previous search execution. The search ID is available in the search_metadata.id or search_metadata.html_url field from initial search responses. |
| `SEARCH_API_GET_LOCATIONS` | Get Locations | Tool to get available locations for geo-localized search queries. Use when you need to find location identifiers for targeting Google searches to specific geographic areas. Returns location metadata including identifiers, names, coordinates, and population reach. |
| `SEARCH_API_SEARCH` | Search | Tool to perform unified search across 40+ search engines including Google, Bing, Yahoo, DuckDuckGo, YouTube, Amazon, and more. Use when you need to retrieve search results with rich structured data including organic results, ads, knowledge graphs, local listings, images, videos, and related searches. Supports advanced filtering by location, language, date, device type, and SafeSearch settings. |

## Creating MCP Server - Stand-alone vs Composio SDK

The Search api MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like DeepSeek Harness, Claude, Cursor, etc. directly to your Search api account. It provides structured and secure access so your agent can act on your behalf using natural language commands.

## Conclusion

### Way Forward
With Search api connected, DeepSeek Harness can now act on your behalf whenever you ask it to.
From here, you can extend the harness further:
- Connect more apps: Calendar, Slack, Notion, Linear, and hundreds of others are available through the same Composio Connect setup, and each new integration adds to what your agent can do for you.
- Build workflows across tools: Once multiple apps are connected, DeepSeek Harness can chain actions together, so it can turn an email into a calendar invite, a Slack message into a Linear ticket, or a meeting note into a follow-up draft.
- Use the plugin system: Wrap common Search api flows as dsh plugins or prompt templates so recurring tasks become one-line commands, and bundle your most-used Search api tools into a named profile you can boot on demand.

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Search api MCP?

With a standalone Search api MCP server, the agents and LLMs can only access a fixed set of Search api tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Search api and many other apps based on the task at hand, all through a single MCP endpoint.

### Can I use Tool Router MCP with DeepSeek Harness?

Yes, you can. DeepSeek Harness fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Search api tools.

### Can I manage the permissions and scopes for Search api while using Tool Router?

Yes, absolutely. You can configure which Search api scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

### How safe is my data with Composio Tool Router?

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Search api data and credentials are handled as safely as possible.
