A2A INTEGRATION · MCP-NATIVE

Use GitDealFlow A2A with Cursor

The AI code editor. Developer-investors who pair-program with their AI.

Crunchbase API: $20K/yr. GitDealFlow A2A: free, no signup.

Cursor supports MCP servers via its Settings → MCP panel. Add our package once, ask the AI to query startups during your code review, and you have inline deal-flow lookup without leaving the editor. The A2A endpoint becomes useful when you want Cursor to call us from a custom Composer prompt without MCP overhead.

MCP server (recommended)

// Cursor → Settings → MCP → Add new server
//
// Name:    GitDealFlow
// Command: npx
// Args:    @gitdealflow/mcp-signal@latest
//
// Or directly edit ~/.cursor/mcp.json:
{
  "mcpServers": {
    "gitdealflow": {
      "command": "npx",
      "args": ["@gitdealflow/mcp-signal@latest"]
    }
  }
}

Custom Composer prompt with curl

// In Composer, paste this prompt template:
//
// "Call https://signals.gitdealflow.com/api/a2a via the Bash tool with this body:
//   {jsonrpc:'2.0',id:1,method:'message/send',params:{message:{role:'user',parts:[{kind:'text',text:'INTENT_HERE'}]}}}
//
// Then summarize the artifacts.parts[0].data.startups list."
//
// Replace INTENT_HERE with the natural-language query.

What you can ask

While reviewing a fintech repo: 'is this commit pattern unusual?'
After looking at package.json: 'who else is shipping ML infra at this velocity?'
During refactor: 'show me developer-tools breakouts for inspiration.'
Before sending an investor update: 'what's the citation string for this dataset?'

Gotchas

Cursor caches MCP server output between calls. Ask it to refresh if you want the latest weekly data after Monday's refresh.
Cursor's AI will sometimes invent startup names if the MCP call returns no match. Always check the GitHub URL field on returned rows.
