What is the JSON5 Resilient Parser MCP Server?

LLMs consistently generate JSON with trailing commas, inline comments, and single quotes. JSON.parse() breaks every time. This MCP catches it all and outputs perfect RFC 8259 JSON.

The Superpowers

Resilient: Accepts trailing commas, comments (// and /**/), single quotes, unquoted keys, hex numbers, and Infinity/NaN.
Strict Output: Always returns valid RFC 8259 JSON that any parser can consume without modification.

Built-in capabilities (1)

parse_json5

parse(). The engine accepts any JSON5-compliant string and returns strict RFC 8259 JSON. Essential for cleaning LLM-generated configs. Parses malformed JSON with trailing commas, comments, single quotes, and unquoted keys — then outputs perfect strict JSON. Powered by JSON5 (32M+ weekly downloads)

FAQ

Frequently asked questions

What makes this different from JSON.parse()?

JSON.parse() rejects trailing commas, comments, single quotes, and unquoted keys. JSON5 accepts all of these and outputs strict RFC 8259 JSON.

Does it support JavaScript-style comments?

Yes. Both single-line (//) and multi-line (/* */) comments are supported and stripped from the output.

Can it handle unquoted object keys?

Yes. {name: 'Alice'} is valid JSON5 and will be converted to {"name": "Alice"} in the strict output.

How does LangChain connect to MCP servers?

Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.

Which LangChain agent types work with MCP?

All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
