Find Anthropic Claude SDK Developer Leads on GitHub

Why Anthropic SDK Developers Are High-Intent Buyers

Developers who star the Anthropic SDKs, open issues about tool_use function calling, or mention claude-opus-4 in their code are not passive learners — they are actively shipping products with Claude. For AI infrastructure vendors, LLM tooling companies, and developer-focused SaaS, these signals represent buyers mid-build who already believe in the Claude platform.

GitHub Signals That Surface Anthropic Claude SDK Developers

GitLeads monitors these signal sources to identify Anthropic Claude SDK developers from GitHub activity:

• New stargazers on anthropic/anthropic-sdk-python, anthropic/anthropic-sdk-typescript, and anthropic/courses
• Keyword mentions of anthropic, claude-opus-4, claude-sonnet-4-6, tool_use, and extended_thinking in GitHub Issues and PRs
• Mentions of @anthropic-ai/sdk, claude-code, and computer_use_20250124 in public code and commit messages
• Stargazers on MCP server repositories: modelcontextprotocol/servers, FastMCP, mcp-framework
• Discussions referencing Anthropic Files API, Batch API, or prompt caching in developer communities

Lead Data GitLeads Captures for Each Signal

For every Anthropic SDK signal event, GitLeads enriches the developer profile with name, public email, company from bio, top languages (Python and TypeScript dominate), follower count, and the exact signal context that triggered the capture.

Routing Claude SDK Leads to Your Sales Stack

// Route Anthropic SDK leads by signal persona
app.post('/webhook/gitleads', async (req, res) => {
  const { developer, signal_type, keyword, repo } = req.body;

  // MCP server builders — platform/tooling buyers
  if (repo?.includes('modelcontextprotocol') || keyword?.includes('mcp-server')) {
    await hubspot.createContact({ ...developer, persona: 'mcp-builder' });
    await slack.post('#ai-platform-leads', formatLead(req.body));
    return res.sendStatus(200);
  }

  // Extended thinking / computer use — advanced API users, high-value
  if (keyword?.includes('extended_thinking') || keyword?.includes('computer_use')) {
    await apollo.addToSequence(developer.email, 'enterprise-ai-sequence');
    return res.sendStatus(200);
  }

  // General Claude API users — nurture pipeline
  await crm.upsertContact({ ...developer, source: 'anthropic-sdk-signal' });
  res.sendStatus(200);
});
