Pallas Athena Tools MCP server

Pallas — athenahealth Integration Engineer for Claude Code

A Claude Code extension that embeds a senior athenahealth integration engineer in your development workflow. Proactively catches data loss bugs, teaches clinical context, guides you through safe DataView queries and API integrations, and gets smarter from every interaction through a built-in learning loop.

Try It in 30 Seconds

No install needed. Add this to any project's .claude/settings.json:

{
  "mcpServers": {
    "athena-tools": {
      "url": "https://pallas-mcp-server.azurewebsites.net/sse"
    }
  }
}

Then open Claude Code and ask: "How do I safely join PATIENT to CHART in DataView?"

This gives you all 12 MCP tools via the hosted server. For the full experience (slash commands, proactive safety rules, CLAUDE.md guidance), use the install method below.

Full Install

npx pallas-athena-tools setup

This installs to your user-level Claude Code config (~/.claude/):

• 12 MCP tools connected to the hosted knowledge base
• 9 slash commands (/sql, /athena-api, /onboard, /diagnose, etc.)
• CLAUDE.md with proactive safety rules and clinical context

Works in every project — no per-project configuration needed.

Other CLI commands

npx pallas-athena-tools status      # Check installation
npx pallas-athena-tools uninstall   # Remove everything

What It Does

• Proactive safety — Flags unsafe joins (46% data loss from PATIENTID/CHARTID mismatch), missing soft-delete filters, hardcoded credentials, and CONTEXTID issues
• Teaches the "why" — Not just "add this filter" but "here's why deleted records exist in healthcare and what happens if you include them"
• Knowledge base — 828 DataView views, 16K+ columns, 1.3K FK relationships, 1.9K API/FHIR/workflow docs
• Learning loop — Every interaction feeds lessons back to the KB. Low-risk patterns auto-merge; high-risk discoveries go through human review
• Working examples — Annotated SQL queries and API code templates in Python, TypeScript, and C#
