biopharma-catalyst-mcp

A forensic biopharma research MCP server — pulls catalyst-grade signals from 6 free, authoritative sources (ClinicalTrials.gov, PubMed, SEC EDGAR, SEC XBRL companyfacts, openFDA, Yahoo Finance) and hands them to your LLM. Includes a server-side aggregator that runs the full forensic workflow in one tool call and returns a deterministic verdict.

Built for the workflow most retail biopharma analysts actually run: a ticker hits the radar, you spend 2–4 hours grinding Google Scholar, FDA pages, EDGAR, and the options chain to decide if the catalyst story holds up. This compresses that to ~30 seconds.

The headline tool: audit_catalyst

Single tool, single call, single verdict. Works on any sponsor / drug combination — no hardcoded tickers anywhere.

Big Pharma example — the "Clean" case

audit_catalyst(ticker="MRK", drug="Keytruda", sponsor="Merck")

→ Verdict: CLEAN (MED)
  Primary finding: Tried to break thesis. Approved 20260424. (1 secondary
                   concern noted in signals)
  Signals fired:
    [A-BEAR] AMENDED_AFTER_COMPLETION_NO_RESULTS — NCT04700072
    [S-BULL] RECENT_FDA_APPROVAL — 20260424
  Math: positive cash flow, IV 29.1%, insider net $0.00M

A CLEAN verdict is the highest praise this tool gives. It means the auditor cross-referenced 9 sources, tried to break the bull thesis, and couldn't (or could only surface secondary concerns that don't outweigh an S-tier bull signal). That's a stronger long signal than a generic "BUY" rating, because failing to break a thesis is harder than confirming it.

The verdict scale:

• CLEAN — tried to break the thesis, couldn't. Confidence drops if A-tier concerns surface.
• FLAG — A-tier bear signal fired without an offsetting S-tier bull. Data ambiguous; look harder.
• BEAR_SIGNAL — at least one S-tier bear fired (terminated trial, FDA rejection, dilution risk, etc.). Confidence rises with multiple S-tier bears.
• BLACK_FLAG — Going Concern disclosed by auditors + cash runway under 6 months. Equity at high risk of zero.
• DISQUALIFIED — insufficient data tied to the company. Try a different drug or query the underlying connectors directly.

The math (cash runway, months to catalyst, insider sentiment, ATM IV, catalyst date) is also returned for the user to inspect. The LLM narrates; the verdict is code.

The Tactical Auditor system prompt (alternative)

If you'd rather have the LLM run the workflow itself across the individual tools, drop this prompt into your MCP client as a custom instruction or system prompt:

You are a Tactical Biopharma Auditor. Your goal is to cross-reference company PR
against raw data from ClinicalTrials.gov, PubMed, SEC EDGAR, openFDA, and the
options market to find discrepancies. You are looking for "Trial Drift" and
"Signal Decay."

When auditing a ticker/drug, run this workflow:

1. Trial Drift Audit (search_clinical_trials)
   - Flag terminations, withdrawals, or COMPLETED status without a results readout.
   - If a Phase 2/3 trial has a completionDate in the past but the market is still
     waiting for "upcoming data," flag the delay as a negative signal.
   - The connector emits an `auditFlag` field; surface it in your output.

2. Literature Signal Check (search_pubmed)
   - Scan abstracts for skepticism keywords: "controversial," "mixed results,"
     "safety concerns," "marginal improvement," "failed to demonstrate."
   - Compare to standard of care if abstracts mention comparators.

3. Filing Density & FDA History (get_sec_filings, get_fda_activity)
   - Count 8-K (current event) frequency. A flurry of 8-Ks before a catalyst
     usually signals structural changes or pre-announcing trouble.
   - Has the drug or sponsor had NDAs marked CRL (rejected), WD (withdrawn), or
     received supplements with regulatory friction?

4. Market Pricing (get_market_data)
   - Check ATM IV. If IV is extremely high (>150%) but the bull case seems
     "certain," the market is pricing a binary failure risk that needs identifying.

Output format:
   * Audit Verdict: [CLEAN / FLAG / BEAR SIGNAL]
     (CLEAN means: tried to break the thesis, couldn't.)
   * Primary Discrepancy: One sentence on the biggest data point that contradicts
     the company's PR.
   * Key Risks: 2-3 specific risks found in CT.gov or PubMed.
   * Data Density: Summary of how much info we actually have vs. how much is
     missing.

Then ask: audit ticker SRPT, drug elevidys (or whatever).

A CLEAN verdict is the highest praise this tool gives — it means the auditor tried to find a hole in the thesis and couldn't. That's a stronger long signal than a generic bull stamp.

Tools

Ten tools — nine raw connectors plus the aggregator:

All sources are free, no API keys required.

Install

git clone https://github.com/yesc97/biopharma-catalyst-mcp.git
cd biopharma-catalyst-mcp
npm install
npm run build

Configure as an MCP server

Add to your MCP client config (e.g. ~/.config/claude/claude_desktop_config.json):

{
  "mcpServers": {
    "biopharma-catalyst": {
      "command": "node",
      "args": ["/absolute/path/to/biopharma-catalyst-mcp/build/index.js"],
      "env": {
        "SEC_USER_AGENT": "Your Name <your-email@example.com>"
      }
    }
  }
}

SEC_USER_AGENT is required by SEC EDGAR — use a real contact email or you'll be rate-limited.

CLI mode

For headless runs without an MCP client:

node build/cli.js <TICKER> "<DRUG_NAME>" "<SPONSOR_NAME>"
node build/cli.js PFE "Comirnaty" "Pfizer"
node build/cli.js MRK "Keytruda" "Merck"
node build/cli.js LLY "Mounjaro" "Eli Lilly"

The CLI prints a structured human-readable snapshot — same data the MCP tools expose.

Why search by drug name, not ticker

Biopharma research signal lives at the pipeline drug level, not the corporate level. Searching CT.gov for "Pfizer" returns hundreds of unrelated trials across every therapeutic area. Searching for Comirnaty returns the specific vaccine trials that drive regulatory outcomes. Always feed the tools the drug name (brand or generic), and use the ticker only for market data + SEC filings.

Live analysis examples

Institutional-grade biopharma research requires analyzing the world's largest pipelines. A few examples from live runs:

audit_catalyst("LLY", "Mounjaro", "Eli Lilly")

Verdict: CLEAN (HIGH)
Primary finding: Tried to break thesis. Strong pipeline density with 10+
                 ongoing Phase 3 trials.
Signals:
  [S-BULL] RECENT_FDA_APPROVAL — 20260315
  [A-BULL] INSIDER_BUYING — net $2.4M over 90d

audit_catalyst("PFE", "Comirnaty", "Pfizer")

Verdict: CLEAN (MED)
Primary finding: Massive data density; no S-tier bear signals detected in
                 last 12 months.
Signals:
  [A-BEAR] 8K_CLUSTER — 4 filings in last 30d (normal for earnings)
  [S-BULL] RECENT_FDA_APPROVAL

audit_catalyst("MRK", "Keytruda", "Merck")

Verdict: CLEAN (MED)
Primary finding: Approved 20260424. (1 secondary concern noted in signals)
