**Build, compose, and run AI agents — directly from your IDE.**

Search genes, create agents with composable genomes, run pipelines in a WASM sandbox, and compete in the Arena.
Zero config. Works with Cursor, Claude Desktop, Windsurf, and any MCP-compatible client.

## Quick Start

### Cursor

Add to `.cursor/mcp.json`:

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

### Claude Desktop

Add to `claude_desktop_config.json`:

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

### Windsurf / Other MCP Clients

Use the same `npx` command — any client that supports MCP stdio transport will work.

## What Can It Do?

### Create and run an agent in one conversation

```
You: "Build me an agent for code security scanning"
AI:  → create_agent({ agent_name: "sec-bot", gene_ids: ["security-scanner", "genesis-code-format"],
                       composition: "Seq" })
     Agent 'sec-bot' created with 2-gene Seq genome.

You: "Run it on my project"
AI:  → agent_run({ agent_name: "sec-bot", input: "{\"path\":\"./src\"}" })
     Pipeline complete — 3 findings, 0 critical.
```

### Search, compare, and compose genes

```
You: "Find the best gene for web search"
AI:  → search_genes({ query: "web search" })
     Found 8 genes. Top match: genesis-web-search (F(g) = 0.87, Native)

You: "Compare it against the lite version"
AI:  → compare_genes({ gene_ids: ["...", "..."] })
     Side-by-side: success rate, latency, fitness breakdown
```

### Full gene lifecycle from your IDE

```
You: "Wrap my function as a gene"
AI:  → wrap_gene({ gene_name: "my-search", domain: "search.web", fidelity: "Wrapped" })
     → compile_gene({ gene_name: "my-search" })
     → test_gene({ gene_name: "my-search", compliance: true })
     → publish_gene({ gene_name: "my-search", changelog: "Initial release" })
```

## Resources (7)

MCP Resources let AI clients reference Rotifer data as context:

| URI Template | Description |
|---|---|
| `rotifer://genes/{gene_id}/stats` | Gene download statistics |
| `rotifer://genes/{gene_id}` | Gene detail + phenotype |
| `rotifer://developers/{username}` | Creator profile + reputation |
| `rotifer://leaderboard` | Top creators by reputation score |
| `rotifer://local/genes` | Local Gene inventory |
| `rotifer://local/agents` | Local Agent registry |
| `rotifer://version` | MCP Server version and update availability |

Each resource returns what the tool of the same job returns, so a declared tool
set covers both: with `--tools=evolve`, `rotifer://genes/{gene_id}/stats`,
`rotifer://developers/{username}` and `rotifer://leaderboard` disappear from the
listing and are refused if read directly, because `get_gene_stats`,
`get_developer_profile` and `get_leaderboard` were not asked for.
`rotifer://version` always answers — it is the server describing itself, not a
capability. Before 0.16.0 these were reachable whatever the tool set said.

## Prompts (4)

MCP Prompts give AI clients guided workflows for common tasks:

| Prompt | Description | Key Arguments |
|--------|-------------|---------------|
| `rotifer-hello` | Interactive agent creation — pick a template and run immediately | `template`, `input` |
| `rotifer-guide` | Understand Rotifer Protocol — genes, agents, Arena, fidelity model | — |
| `rotifer-architect` | Design an Agent — task-driven gene search + composition planning | `task` |
| `rotifer-challenge` | Arena evaluation — submit a gene, compare with competitors | `gene` |

Try asking your AI: *"Use the rotifer-hello prompt to build me an agent"* or *"Use rotifer-architect to design an agent for document Q&A"*.

## Configuration

Zero-config by default — connects to the public Rotifer Cloud API.

To use a custom endpoint, create `~/.rotifer/cloud.json`:

```json
{
  "endpoint": "https://your-supabase-instance.supabase.co",
  "anonKey": "your-anon-key"
}
```

Or set environment variables:

```bash
ROTIFER_CLOUD_ENDPOINT=https://your-instance.supabase.co
ROTIFER_CLOUD_ANON_KEY=your-anon-key
```

### Choosing which tools to expose

All thirty-one tools are available by default. `ROTIFER_MCP_TOOLS` narrows that
