You’re screening antibody candidates for a biopharma project and need to check whether similar sequences already appear in published patents—without juggling browser tabs, spreadsheets, and BLAST portals. This tutorial walks you through installing PatSnap Biology Modality MCP in your AI environment. You’ll connect your AI assistant to 1.4B+ biosequences and 208M+ patents, enabling live patent and sequence searches inside your conversation. Setup takes one JSON configuration file and an API key—no command-line tools, no dependencies.
What You Will Accomplish
By the end of this tutorial, you’ll have connected your AI environment to patent and biosequence databases through the
Model Context Protocol (MCP)—an open standard from
Anthropic that lets AI assistants query external databases during a conversation. Once installed, you can search sequences, align antibodies, fetch patent records, and identify modifications without leaving your AI chat.
Who Built This MCP
This guide uses
PatSnap Biology Modality MCP—built by
PatSnap, the patent intelligence platform indexing 208M+ patents across 174 jurisdictions. The MCP draws from
WIPO,
USPTO, EPO, CNIPA, and other global patent offices, updated daily.
What You Can Do With the MCP
Once the MCP is connected, your AI assistant can run these workflows live:
Sequence similarity search: Paste a candidate antibody sequence, ask “Find similar patented sequences,” and get ranked results with percent identity, e-value, and patent metadata—all in the conversation.
Antibody-antigen lookup: Type “Show me all patented antibodies targeting PD-1” and receive a list of antibody records with assignee names, filing dates, and sequence IDs.
Patent sequence extraction: Ask “Extract all sequences from patent US10287356B2” and get every sequence disclosed in that document.
Modification search: Query “Find PEGylated antibodies in patents filed after 2020” to surface biologics with specific post-translational modifications.The MCP returns results directly in your chat—no browser tabs, no copy-paste between tools.
Prerequisites
Before you start, make sure you have:
- MCP-compatible AI environment: Claude Desktop, Claude Code, Cursor, Continue.dev, or any client listed at the MCP marketplace
- API key: Get yours from the MCP marketplace after signup (10,000 free credits, no credit card)
Step 1: Get Your API Key
Go to the
MCP marketplace, find
Biology Modality MCP, and generate your API key. Copy the key—you’ll paste it into the configuration file in the next step.Your key starts with 10,000 free credits. Sequence searches cost credits per query; the exact amount depends on database size and complexity. Pay-as-you-go pricing applies after you use the free tier.
Step 2: Add the MCP to Your Configuration
Locate your MCP configuration file:
- Claude Desktop (macOS):
~/Library/Application Support/Claude/claude_desktop_config.json - Claude Desktop (Windows):
%APPDATA%\Claude\claude_desktop_config.json - Cursor: Settings → Features → MCP Servers
- Continue.dev:
~/.continue/config.json
Open the file and add this JSON block. Replace
YOUR_API_KEY with the key you copied in Step 1:
{
"mcpServers": {
"biology_modality": {
"url": "https://connect.patsnap.com/06e741/logic-mcp?apikey=YOUR_API_KEY",
"type": "streamableHttp"
}
}
}
Save the file and restart your AI environment. The MCP will load automatically on launch.
Configuration notes: - The server name
biology_modality can be any string—your AI won’t see it. streamableHttp tells the MCP client to use HTTP streaming for async operations like sequence search.- If you already have other MCPs configured, add this block inside the existing
mcpServers object (separate with commas).
Step 3: Try It Out
Open your AI environment and try this query:“Find all patented antibodies targeting PD-1.”If the MCP is connected, you’ll see results showing thousands of antibody records. Here’s what the output looks like:
Example output (PD-1 antibody query):14,725 patented antibodies across all species. Top antibodies: Pembrolizumab (17 records), Nivolumab (11), LZM-009 (7). Top assignees: Bristol-Myers Squibb (969), Novartis (579), Regeneron (487).
Results include species breakdown, antibody names, and assignee names. That means you’re connected.If you don’t see results, check the Troubleshooting section below.
Example Prompts
Once connected, try these queries:
“Find similar sequences to [your sequence] in patents filed after 2020.”Returns ranked matches with percent identity, query coverage, e-value, and patent numbers. Use this to check if a candidate sequence overlaps with existing IP.
“Show me all patented antibodies against EGFR.”Lists antibody records targeting your antigen of interest, grouped by assignee and filing date. Use this for competitive intelligence or FTO research.
“Extract all sequences from patent WO2023001234A1.”Pulls every sequence disclosed in a specific patent. Useful when you have a patent number and need the raw sequences for alignment or analysis.
“Find PEGylated antibodies in patents from Amgen.”Searches for biologics with specific post-translational modifications from a single assignee. Combine modification filters with assignee, date, or jurisdiction filters to narrow results.
Troubleshooting
| Symptom | Cause | Fix |
|---|
| No MCP tools appear in AI environment | Configuration file not saved or incorrect path | Verify file location for your platform. Restart AI environment after editing. |
| “API key invalid” error | Key copied incorrectly or expired | Regenerate key at MCP marketplace. Check for extra spaces in JSON. |
| Sequence search returns no results | Sequence format issue or no high-similarity matches in database | Try a known patented sequence (e.g., pembrolizumab VH) to confirm MCP is working. Check sequence format—no line breaks, DNA/protein mismatch. |
| Timeout on large queries | Query too broad for async polling | Narrow query by adding date range, assignee, or jurisdiction filter. For BLAST-style searches, wait for polling to complete—large searches take longer. |
Next Steps
Now that the MCP is installed, you can:
- Run your first patent sequence search: Paste a candidate antibody sequence and ask “Find similar patented sequences.” Review percent identity and e-value to assess IP risk.
- Explore other MCPs: Add Chemical Molecular MCP for structure search and ADMET data, or Pharma Intelligence MCP for clinical trials and pipeline information.
- Try the web interface: If you want to explore the same database without installing anything, go to PatSnap Eureka and start searching immediately.
- Learn more about biologics IP: Browse biologics patent analysis articles on the PatSnap blog.
