scoretracker4321/json-mcp-lite

Turn a JSON file into an **MCP server** in one command, so Claude Desktop, Claude Code, Cursor or any stdio MCP client can browse and search your data.
Give it a catalogue, an FAQ, a price list or a docs index, and it creates three read-only tools:
| Tool | What it does |
|---|---|
| _list | List records, with limit / offset paging |
| _search | Keyword search; every word must match, case-insensitive |
| _get | One record by its id field |
MIT licence. Node.js 20+. Two dependencies: the official @modelcontextprotocol/sdk and zod.
Try it
Use it with Claude Desktop or Cursor
Claude Code:
Then ask: *"Which teas are under ₹400 and in stock?"* or *"Show me product MUG-001."*
Options
| Flag | Default | Meaning |
|---|---|---|
| --file | (required) | The JSON file |
| --path | root | Dot path to the array inside the file, e.g. data.items |
| --name | records | Tool name prefix: products → products_list, … |
| --id | id | Field used by _get |
| --search | all fields | Comma-separated fields that _search looks in |
Need more than a JSON file?
**json-mcp-lite** is the free, local, single-file part of **MCP Server Kit** ($29, one-time). The Kit adds:
- **Any REST API → MCP tools** from its OpenAPI 3 spec: one typed tool per operation, auth injected from env, read-only filter, include/exclude lists
- **Remote hosting** over Streamable HTTP (stateless, proxy-friendly), not only stdio
- **API-key auth** and **per-key rate limits**, CORS, /health and /tools endpoints
- **Several sources in one server**, set up in one YAML/JSON config file
- **Docker** image, an Express router to mount inside your own app, and deploy guides
