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 Basecamp 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. ## Also integrate Basecamp with - [ChatGPT Work](https://composio.dev/toolkits/basecamp/framework/chatgpt) - [Antigravity](https://composio.dev/toolkits/basecamp/framework/antigravity) - [OpenAI Agents SDK](https://composio.dev/toolkits/basecamp/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/basecamp/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/basecamp/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/basecamp/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/basecamp/framework/codex) - [Grok Build](https://composio.dev/toolkits/basecamp/framework/grok-build) - [Cursor](https://composio.dev/toolkits/basecamp/framework/cursor) - [VS Code](https://composio.dev/toolkits/basecamp/framework/vscode) - [OpenCode](https://composio.dev/toolkits/basecamp/framework/opencode) - [OpenClaw](https://composio.dev/toolkits/basecamp/framework/openclaw) - [Hermes](https://composio.dev/toolkits/basecamp/framework/hermes-agent) - [Pi](https://composio.dev/toolkits/basecamp/framework/pi-agent) - [Google ADK](https://composio.dev/toolkits/basecamp/framework/google-adk) - [LangChain](https://composio.dev/toolkits/basecamp/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/basecamp/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/basecamp/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/basecamp/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/basecamp/framework/crew-ai) - [Pydantic AI](https://composio.dev/toolkits/basecamp/framework/pydantic-ai) - [AutoGen](https://composio.dev/toolkits/basecamp/framework/autogen) ## 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 Basecamp 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 Basecamp MCP server, and what's possible with it? The Basecamp MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Basecamp account. It provides structured and secure access so your agent can perform Basecamp operations on your behalf. ## Supported Tools None listed. ## Supported Triggers None listed. ## Creating MCP Server - Stand-alone vs Composio SDK The Basecamp 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 Basecamp account. It provides structured and secure access so your agent can act on your behalf using natural language commands. ## Complete Code None listed. ## Conclusion ### Way Forward With Basecamp 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 Basecamp flows as dsh plugins or prompt templates so recurring tasks become one-line commands, and bundle your most-used Basecamp tools into a named profile you can boot on demand.

With a standalone Basecamp MCP server, the agents and LLMs can only access a fixed set of Basecamp tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Basecamp 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 Basecamp tools. ### Can I manage the permissions and scopes for Basecamp while using Tool Router? Yes, absolutely. You can configure which Basecamp 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 Basecamp data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
