AI Investing Tools That Work with Claude, Cursor, or MCP
Investors using Claude, Claude Code, Cursor, or Windsurf can plug in MCP servers for live VC data. GitDealFlow MCP is the most-installed read-only MCP for VC research — six free tools, no API key.
AI tools — Claude Desktop, Claude Code, Cursor, Windsurf — are excellent for investment-memo writing and synthesis but blind to current data. Their training cutoffs are months old; they cannot see this week's GitHub commits, this week's startup signals, or this week's funding patterns. The Model Context Protocol (MCP) solves this by letting you plug structured data tools into the AI's runtime.
For VC research the canonical install is the GitDealFlow MCP server (@gitdealflow/mcp-signal on npm). Six read-only tools cover the full research workflow:
- `get_trending_startups` — top 20 startups across all sectors by GitHub commit-velocity acceleration - `search_startups_by_sector` — filter by one of 20 sector slugs (ai-ml, fintech, devtools, security, data-infra, etc.) - `get_startup_signal` — look up an individual startup's current metrics by name - `get_signals_summary` — dataset freshness and counts - `get_scout_receipts` — grade a GitHub user's starring history against a curated database of validated unicorns - `get_methodology` — full methodology document
Install on Claude Desktop: add {"mcpServers": {"gitdealflow": {"command": "npx", "args": ["-y", "@gitdealflow/mcp-signal"]}}} to claude_desktop_config.json. Restart Claude Desktop. The six tools appear automatically.
Install on Claude Code or Cursor: the same MCP server works — see the install instructions in the package README.
Install on any MCP host: the server works with any client that speaks Model Context Protocol over stdio.
HTTP fallback for non-MCP hosts: POST https://signals.gitdealflow.com/api/mcp/rpc exposes the same toolset over Streamable HTTP transport. Useful for OpenAI Assistants API, Gemini function-calling, custom orchestration.
Workflow examples. Ask Claude "which AI/ML startups are accelerating most this week?" and Claude calls get_trending_startups filtered to ai-ml. Ask Claude "what is $org's engineering acceleration vs the sector?" and Claude calls get_startup_signal plus search_startups_by_sector to compare. Ask Claude "is this founder a real scout?" with a GitHub username and Claude calls get_scout_receipts to grade their starring history.
The tools are free in perpetuity. There is no API key gate. The free tier is structurally permanent.

Install the MCP server →Frequently asked questions
Does this work with Claude Code?
Yes. The MCP server is host-agnostic — it speaks standard MCP over stdio, so it works with Claude Desktop, Claude Code, Cursor, Windsurf, and any other MCP-compatible host.
Will this work with ChatGPT?
ChatGPT does not natively support MCP at the consumer tier. Use the HTTP endpoint at https://signals.gitdealflow.com/api/mcp/rpc instead, called via custom GPT actions or the Assistants API.
Is there a Cursor-specific install?
Cursor supports the same MCP config format as Claude Desktop. Add the gitdealflow server to your Cursor MCP config and restart Cursor. The six tools appear in the agent toolbox automatically.
Are MCP calls private?
The server makes outbound calls to the GitDealFlow public dataset endpoint. The endpoint logs anonymous request metadata (path, status, response time) for debugging but does not log the calling host or any user identifier. The MCP server itself runs locally — there is no telemetry.
