## Available in

The server is published to the canonical MCP catalogues, so registry-aware clients can discover and install it directly — or use any command in [Quick Start](#quick-start) below.

- **[npm](https://www.npmjs.com/package/@creedspace/mcp-server)** — `@creedspace/mcp-server`, the package every install path resolves to.
- **[Official MCP Registry](https://registry.modelcontextprotocol.io/v0/servers?search=io.github.Creed-Space/creedspace-mcp-server)** — `io.github.Creed-Space/creedspace-mcp-server`.
- **[GitHub](https://github.com/Creed-Space/creedspace-mcp-server)** — source, issues, and the `server.json` manifest.
- **[Smithery](https://smithery.ai/server/nell/creedspace)** — `nell/creedspace`, a gateway-fronted Streamable HTTP endpoint.

Also rolling out across the wider MCP ecosystem: [mcp.directory](https://mcp.directory), [mcpservers.org](https://mcpservers.org), [PulseMCP](https://www.pulsemcp.com) (via the registry ingest), and [mcp.so](https://mcp.so).

## Platform Integration Examples

### OpenAI Agents SDK (HTTP Transport)

```python
from agents import Agent
from agents.mcp import MCPServerStreamableHttp

# Start the server first:
# npx @creedspace/mcp-server --transport http --port 3100

server = MCPServerStreamableHttp(
    url="http://localhost:3100/mcp",
    name="creedspace"
)

agent = Agent(
    name="safe-agent",
    tools=[server.get_tools()]
)

# The agent now has access to Creed Space safety tools
```

### OpenAI Codex (STDIO Transport)
