Fix LLM JSON Output in the OpenAI Agents SDK

The `parse_json5` tool takes whatever malformed JSON garbage your agent spits out and converts it into strict RFC 8259 format. Language models love to generate trailing commas, single quotes, and random inline comments. You pass that text directly to this endpoint. Your system stays online instead of crashing with a syntax error. Built-in guardrails then validate the cleaned output before the agent executes the next step. You get reliable data pipelines without writing custom regex hacks.

Handle Unquoted Keys and Comments

Using the `parse_json5` function allows your system to accept human-written configuration files directly. Developers leave comments in their JSON payloads all the time. Standard parsers reject those payloads immediately. This MCP Server eats those edge cases alive. It processes unquoted keys and block comments using the battle-tested JSON5 engine. Your tracing dashboard just shows a successful parse event.

Drop-in MCP Server Integration

Calling `parse_json5` requires zero custom routing when you use the standard auto-discovery features. You pass the server to your Agent constructor. The setup takes about two minutes. Caching the tool list boosts performance for high-volume endpoints. The agent knows exactly when to call the parser before handing off data to a specialized downstream worker.

Setup guide

Set up JSON5 Resilient Parser MCP in OpenAI Agents SDK

Prerequisites

Python 3.10+ installed
openai-agents package (pip install openai-agents)
Active Vinkius subscription with a valid endpoint token

1

Install the SDK

Run pip install openai-agents to install the OpenAI Agents SDK. The MCP integration is built-in — no extra dependencies needed.
2

Connect via SSE transport

Use MCPServerSse with your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. The SDK auto-discovers all JSON5 Resilient Parser tools at runtime.
3

Create your Agent

Pass the MCP to Agent(mcp_servers=[server]). The agent receives JSON5 Resilient Parser tools as native definitions — JSON schemas resolve automatically.
4

Run the agent

Call Runner.run(agent, prompt) to execute. The agent invokes the appropriate JSON5 Resilient Parser tools and returns structured results. Copy the full example on the right to get started.

agent.py

import asyncio
from agents import Agent, Runner
from agents.mcp import MCPServerSse

async def main():
    async with MCPServerSse(
        url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    ) as server:
        agent = Agent(
            name="JSON5 Resilient Parser Agent",
            instructions="You have access to JSON5 Resilient Parser tools.",
            mcp_servers=[server],
        )
        result = await Runner.run(agent, "List recent transactions")
        print(result.final_output)

asyncio.run(main())

Common questions about JSON5 Resilient Parser MCP in OpenAI Agents SDK

Install the pip package and create an MCPServerStreamableHttp instance. Pass it to your Agent constructor's server list. The SDK handles tool discovery automatically.

Yes. The parser cleans the syntax first. Your guardrails then evaluate the strict JSON output to ensure it meets your specific business rules.

Standard parsers fail hard on trailing commas and comments. This server fixes those exact syntax quirks. Your production agents stop throwing unexpected exceptions.

The engine accepts it without complaints. It converts the single quotes to double quotes. The final output is completely standard JSON.

Your raw string payloads stay completely ephemeral during the parse operation. The V8 Isolate Sandbox processes the text and instantly destroys the memory state. No logs keep your broken configs.
