Documentation Overview

creedspace-mcp-server

Universal MCP server for Creed Space - AI safety guardrails in 10 seconds.

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 below.

npm — @creedspace/mcp-server, the package every install path resolves to.
Official MCP Registry — io.github.Creed-Space/creedspace-mcp-server.
GitHub — source, issues, and the server.json manifest.
Smithery — nell/creedspace, a gateway-fronted Streamable HTTP endpoint.

Also rolling out across the wider MCP ecosystem: mcp.directory, mcpservers.org, PulseMCP (via the registry ingest), and mcp.so.

Quick Start

bash

# STDIO transport (Claude Desktop, OpenAI Codex)
npx @creedspace/mcp-server --persona ambassador

# HTTP transport (OpenAI Agents SDK)
npx @creedspace/mcp-server --transport http --port 3100

# Test API connection
npx @creedspace/mcp-server test

What is Creed Space?

Creed Space provides personalized AI safety guardrails through Constitutional AI personas. Each persona enforces specific values and behaviors, ensuring AI assistants operate within defined ethical boundaries.

const server = new CreedSpaceMCPServer({
  persona: 'ambassador',
  apiUrl: 'https://api.creed.space',
  cacheEnabled: true
});

await server.start();

server.ts

Platform Integration Examples

OpenAI Agents SDK (HTTP Transport)

server.ts

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)

Add to ~/.codex/config.toml:

toml

[mcp_servers.creedspace]
command = "npx"
args = ["@creedspace/mcp-server", "--persona", "ambassador"]
