Setup snapshot

  1. 1

    Setup complexity is LOW. This package is likely designed for quick installation with minimal external side-effects.

  2. 2

    Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

You have access to TruthStack reference data tools. When users ask about
supplement and medication combinations, use check_interactions to look up
published evidence rather than relying on training data alone.

When presenting results:
- State what the evidence shows, not what is "safe" or "unsafe"
- Mention FDA adverse event report counts when available
- Note CYP pathway considerations
- Always recommend discussing findings with a healthcare provider
- Make clear this is reference data, not medical advice
- Use explain_interaction when users want to understand the evidence

Full README

TruthStack MCP Server

Structured supplement interaction and evidence data for AI agents via the Model Context Protocol.

TruthStack provides machine-readable reference data about dietary supplements and their documented interactions with prescription medications. Instead of relying on LLM training data — which frequently hallucinates supplement information — your agent calls TruthStack for structured, cited evidence from published literature and FDA adverse event reports.

Important: This is informational reference data only. It is not medical advice, not a medical device, and not intended to diagnose, treat, cure, or prevent any disease. Always consult a healthcare provider before making changes to supplements or medications. Our database covers a growing set of compounds and may not be exhaustive.

What It Returns

| Tool | What It Returns | When to Use | |------|----------------|-------------| | check_interactions | Evidence on supplement + medication combinations: reported signals, CYP pathway data, evidence balance | User mentions supplements + meds together | | search_compounds | Fuzzy name resolution (584 aliases, handles misspellings and brand names) | Need to resolve messy input ("mag gly", "KSM-66") | | get_compound_info | Full compound profile + all documented interactions | Deep dive on a specific supplement | | explain_interaction | Human-readable explanation: mechanism, evidence summary, published sources | User asks "why might this be a concern?" | | get_evidence_balance | Raw evidence: FAERS report counts, CYP data, research grades, evidence balance | Need to cite sources or provide provenance |

Data Sources

  • FDA FAERS — 805 adverse event reporting signals from pharmacovigilance data
  • FDA Drug Labels — CYP450 pathways, contraindications, botanical warnings
  • PubMed / ClinicalTrials.gov — 220 research findings with evidence grading
  • 584 compound aliases — misspellings, brand names, abbreviations, product forms

Quick Start

1. Get API Key

Contact chris@truthstack.co or visit truthstack.co

2. Install

git clone https://github.com/TruthStack1/truthstack-mcp.git
cd truthstack-mcp
npm install

3. Configure Claude Desktop

Edit ~/.claude/claude_desktop_config.json:

{
  "mcpServers": {
    "truthstack": {
      "command": "node",
      "args": ["/path/to/truthstack-mcp/server.js"],
      "env": {
        "VAULT_API_URL": "https://api.truthstack.co",
        "VAULT_API_KEY": "your-api-key"
      }
    }
  }
}

Restart Claude Desktop. You'll see TruthStack tools available in the tool picker.

4. Try It

Ask Claude: "What does published research say about taking ashwagandha with sertraline?"

Claude will call check_interactions and return structured evidence including FDA adverse event report counts and CYP pathway data.

REST API

Every MCP tool maps to a REST endpoint:

| MCP Tool | REST Endpoint | |----------|--------------| | check_interactions | POST /api/interactions/check | | search_compounds | GET /api/compounds/search?q={query} | | get_compound_info | GET /api/compounds/{id} | | explain_interaction | Composite endpoint | | get_evidence_balance | Composite endpoint |

Base URL: https://api.truthstack.co · Auth: X-API-Key header · Docs: https://api.truthstack.co/docs

Intended Use & Limitations

  • This is a reference data API, not a medical device or clinical decision support system
  • Returns structured summaries of published research and adverse event reporting data
  • Not exhaustive — our database covers a growing but incomplete set of compounds and interactions
  • Cannot see your full medical history — results reflect only the substances you specify
  • Does not diagnose, prescribe, or recommend treatments
  • Does not replace pharmacists, physicians, or institutional drug interaction systems
  • Outputs should be presented to end users with appropriate context and limitations

System Message Guidance

If building a health-aware agent, consider including guidance like:

You have access to TruthStack reference data tools. When users ask about
supplement and medication combinations, use check_interactions to look up
published evidence rather than relying on training data alone.

When presenting results:
- State what the evidence shows, not what is "safe" or "unsafe"
- Mention FDA adverse event report counts when available
- Note CYP pathway considerations
- Always recommend discussing findings with a healthcare provider
- Make clear this is reference data, not medical advice
- Use explain_interaction when users want to understand the evidence

  • Compound contributions — know of missing supplement aliases or interactions? Open an issue
  • Framework examples — help us add examples for CrewAI, AutoGen, LlamaIndex
