The Rotifer gene ecosystem is now accessible to any AI agent that speaks MCP. One command, zero configuration:

npx @rotifer/mcp-server

Add it to your MCP client config and your agent can search, inspect, execute, and compare genes from the cloud registry — directly within conversations.

What It Does

@rotifer/mcp-server exposes Rotifer's Cloud API as MCP tools and resources. Your AI agent gets:

7 Tools

Tool	Description
`list_genes`	Search and browse the gene registry with filters
`get_gene`	Get detailed gene info including phenotype and README
`run_gene`	Execute a gene with custom input
`compare_genes`	Side-by-side comparison of two genes
`get_gene_stats`	Download statistics by time period (7d/30d/90d)
`get_leaderboard`	Developer reputation rankings
`get_developer_profile`	Developer profile and reputation data

5 MCP Resources

Resource URI	Description
`rotifer://genes/{id}`	Gene details
`rotifer://genes/{id}/stats`	Gene statistics
`rotifer://developers/{username}`	Developer profile
`rotifer://leaderboard`	Global leaderboard
`rotifer://local/genes`	Scan local workspace for installed genes

Local Gene Discovery

The list_local_genes tool scans your workspace for installed genes and returns metadata, compile status, and cloud origin — bridging your local development with the cloud registry.

Setup

Cursor

{
  "mcpServers": {
    "rotifer": {
      "command": "npx",
      "args": ["@rotifer/mcp-server"]
    }
  }
}

Claude Desktop

    "rotifer": {
      "command": "npx",
      "args": ["@rotifer/mcp-server"]
    }
  }
}

Works with any MCP-compatible client. Zero API keys required — the server uses the public Cloud API by default.
