Common questions
Is JSON MCP Lite safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).
Is it still maintained?
The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 31 days ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need MCPB on your computer.
What can I use instead?
In the same category: Context7, Codebase Memory, Exa

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
git clone https://github.com/scoretracker4321/json-mcp-litecd json-mcp-lite && npm install npm start # serves examples/products.json on stdio npm test
Use it with Claude Desktop or Cursor
{"mcpServers": { "products": { "command": "node", "args": [ "/abs/path/json-mcp-lite/src/server.js", "--file", "/abs/path/products.json", "--name", "products", "--id", "sku", "--search", "title,description" ] } } }
Claude Code:
claude mcp add products -- node /abs/path/json-mcp-lite/src/server.js --file /abs/path/products.json --name products --id skuThen 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,
/healthand/toolsendpoints - 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
