ddg-agent-services-mcp 0.3.1

Payment-aware MCP server + multi-framework SDK for DDG Agent Services (109 services, 90 paid x402/direct-crypto operations, OpenAI-compatible gateway)

DDG Agent-Payable Services

109 x402/direct-crypto services for AI agents, exposed as 114 OpenAPI operations. DDG covers low-cost utilities, GPU-backed AI services, OpenAI-compatible chat/embedding routes, and specialized agent-commerce proof work. Use DDG when an agent needs a callable service now, or when a seller needs payment readiness, MCP security, discovery repair, browser proof, repo context, receipts, and marketplace-ready artifacts.

Best first calls

Route	Price	Use it when
/v1/tx-smoke-test	$0.01	Prove your agent can complete a paid DDG request and receive a receipt.
/v1/site-audit	$0.03	Buy a low-cost read-only artifact and verify paid artifact delivery.
/v1/agent-readiness-scorecard	$0.01	Score discovery, OpenAPI, llms.txt, payment 402 behavior, MCP status, and agent-commerce signals.
/v1/agent-discovery-pack	$0.01	Repair llms.txt, OpenAPI, pricing/catalog JSON, examples, and agent-readable docs.
/v1/agent-payment-readiness-audit	$0.02	Audit x402/MPP/402 readiness, idempotency, receipts, and discovery assets.
/v1/mcp-tool-security-audit	$0.02	Review MCP/tool permissions, auth boundaries, prompt-injection exposure, and dangerous capabilities.

DDG is not only a generic model gateway. The gateway exists, but the defensible wedge is agent-commerce audits, proof artifacts, and security/discovery repair that broad model routers usually do not sell.

Quick Start

MCP one-liner

DDG_MCP_AGENT_ID=your-agent uvx --from ddg-agent-services-mcp ddg-agent-services-mcp

One-liner SDK (zero framework deps)

from ddg_agent_services_mcp import ddg

client = ddg(agent_id="my-agent", private_key="0x...")
result = client.post("/v1/site-audit", {"url": "https://example.com"})

Or configure once via environment:

export DDG_AGENT_ID="my-agent"
export DDG_PRIVATE_KEY="0x..."

from ddg_agent_services_mcp import ddg
client = ddg()  # reads from env

OpenAI-compatible gateway

Drop-in replacement for openai-python — point any OpenAI client at DDG:

from ddg_agent_services_mcp import create_openai_client

client = create_openai_client(agent_id="my-agent", private_key="0x...")
response = client.chat.completions.create(
    model="auto",
    messages=[{"role": "user", "content": "Hello"}],
)
print(response.choices[0].message.content)

Supported routes: GET /v1/models, POST /v1/chat/completions, POST /v1/embeddings

Or use the standard openai package directly:

from openai import OpenAI
client = OpenAI(
    base_url="https://agents.daedalusdevelopmentgroup.com/v1",
    api_key="ddg-x402",
    default_headers={"X-Agent-Id": "my-agent"},
)

Install

pip install ddg-agent-services-mcp

# With framework support:
pip install ddg-agent-services-mcp[langchain]     # or crewai, openai-agents, autogen, etc.
pip install ddg-agent-services-mcp[all-frameworks] # everything

Use with any framework

from ddg_agent_services_mcp.tools import create_langchain_tools

tools = create_langchain_tools(
    agent_id="my-agent",
    private_key="0x...",  # Your EVM wallet key (Base USDC)
)
# Pass tools to your LangChain agent

8 frameworks supported: LangChain, CrewAI, OpenAI Agents SDK, AutoGen, PydanticAI, LlamaIndex, Google ADK, and MCP.
