How to Use the GenBank/NCBI API MCP in Claude Code

Q: How do I use Claude Code to run a search against the GenBank/NCBI API in a cron job?

In your crontab, add a line with the full claude mcp run command. You can specify the search term and database with flags and pipe the output to a log file for nightly sequence monitoring.

Q: How can my script see all available databases in the GenBank/NCBI API using Claude Code?

Just run claude mcp run genbankncbi-api-mcp listncbidatabases. The output is a clean list you can parse with grep, awk, or any other terminal tool to find what you need.

Q: Is there a way to check if the NCBI API is up from a bash script?

Absolutely. Use claude mcp run genbankncbi-api-mcp checkapistatus in an if statement. You can check its exit code to control your script's flow based on whether the API is available.

Pipe NCBI genomic data directly into your terminal scripts. This headless MCP server is built for CI/CD and automation with Claude Code.

Automate Sequence Discovery in Shell

Use `search_ncbi_sequences` to find sequence UIDs directly from your command line. You can build a shell script that searches for new sequences every night and logs the results. For example: `claude mcp run genbankncbi-api-mcp search_ncbi_sequences --query "human[orgn] AND topoisomerase[protein]" --database "protein"`. You get a clean list of UIDs. Pipe this output directly into `xargs` or another command-line tool to trigger the next step in your bioinformatics pipeline. It's designed for headless execution in cron jobs or CI/CD runners.

Batch-Process Sequence Summaries

Once your script has a list of UIDs, use `get_ncbi_summary` to pull details for each one. This is perfect for batch jobs that need to enrich data, like adding gene definitions to a list of IDs before loading them into a database. Because Claude Code is terminal-based, you can easily wrap this in a loop. A simple `for` loop in bash can process thousands of UIDs overnight, fetching and formatting the data exactly how you need it, without any manual intervention. This is what a CLI-focused MCP tool should do.

Scriptable Endpoint and Database Checks

Before running a critical pipeline, use `check_api_status` as the first step in your script. If the command fails, you can have the script exit and send an alert, preventing a larger failure downstream. It's a simple guarantee for your automated jobs. Likewise, you can use `list_ncbi_databases` to programmatically validate that a database you rely on still exists. Things change. This MCP server lets your scripts adapt instead of just breaking when an upstream dependency is altered.

Setup guide

Set up GenBank/NCBI API MCP in Claude Code

Prerequisites

Claude Code CLI installed (npm install -g @anthropic-ai/claude-code)
Active Vinkius subscription with a valid endpoint token

1

Run the add command

Open your terminal and run the command shown on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com. Use --scope user to make it available across all projects.
2

Verify the connection

Start a Claude Code session and type /mcp to list connected servers. You should see genbankncbi-api-mcp with a green status indicator.
3

Start using tools

Ask Claude Code something like "Check my latest GenBank/NCBI API transactions." It will automatically discover and invoke the available GenBank/NCBI API tools.

Terminal

claude mcp add --transport http genbankncbi-api-mcp https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp

Prerequisites

Claude Code CLI installed
Active Vinkius subscription with a valid endpoint token

1

Open the config file

Create or edit .mcp.json in your project root for project-level scope, or ~/.claude.json for user-level scope.
2

Add the GenBank/NCBI API MCP

Paste the JSON snippet shown on the right into the mcpServers object. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Restart Claude Code

Start a new Claude Code session. Type /mcp to confirm the server is connected. The tools will be automatically available in your conversation.

Common questions about GenBank/NCBI API MCP in Claude Code

In your crontab, add a line with the full `claude mcp run` command. You can specify the search term and database with flags and pipe the output to a log file for nightly sequence monitoring.

Yes. You can use standard shell commands with this MCP. For example: `cat uids.txt | xargs -I {} claude mcp run genbankncbi-api-mcp get_ncbi_summary --id {}`. This will execute the command for each ID in the file.

Just run `claude mcp run genbankncbi-api-mcp list_ncbi_databases`. The output is a clean list you can parse with `grep`, `awk`, or any other terminal tool to find what you need.

Absolutely. Use `claude mcp run genbankncbi-api-mcp check_api_status` in an `if` statement. You can check its exit code to control your script's flow based on whether the API is available.

The MCP server acts as a stateless proxy. Your genomic search terms and the API's response, like sequence UIDs, pass through an ephemeral instance that is destroyed after the request. No query data is persisted.
