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(). 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)

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 Mastra AI connect to MCP servers?
Create an MCPClient with the server URL and pass it to your agent. Mastra discovers all tools and makes them available with full TypeScript types.
Can Mastra agents use tools from multiple servers?
Yes. Pass multiple MCP clients to the agent constructor. Mastra merges all tool schemas and the agent can call any tool from any server.
Does Mastra support workflow orchestration?
Yes. Mastra has a built-in workflow engine that lets you chain MCP tool calls with branching logic, error handling, and parallel execution.
