Overview
Format JSON, convert data, inspect tokens and certificates, and generate test fixtures without leaving your AI workflow. dot.tools brings everyday developer utilities to your assistant through one free, hosted MCP endpoint. No signup, API key, or local server required.
Tools
- Format and compare: JSON and XML formatting, SQL beautification, and text/JSON diffs.
- Convert data: YAML to/from JSON, CSV to/from JSON, JSON to TypeScript, naming conventions, and number bases.
- Encode and inspect: Base64, URL encoding and parsing, HTML entities, JSON escaping, JWT decoding, and certificate inspection.
- Generate: UUIDs, passwords, mock datasets, and QR codes. Calculate hashes without asking the model to invent them.
- Work with infrastructure data: CIDR calculations, cron explanations and next run times, Unix timestamps, and chmod permissions.
- Check schemas and colors: Validate JSON against a schema, infer schemas from sample data, convert color codes, and check contrast ratios.
All 28 tools are discoverable through MCP, with input schemas your assistant can use to construct calls. Results are returned as JSON-formatted text.
Example requests
Once connected, ask your assistant:
- "Convert this JSON response to TypeScript interfaces."
- "Generate 20 mock customer records with names and email addresses as JSON."
- "Explain
0 9 * * 1-5and show the next five run times in UTC." - "Compare these JSON documents, ignoring object key order."
- "Check the contrast ratio between
#334155and#ffffff."
Connect
Add https://dot.tools/mcp as a remote MCP server in a client that supports Streamable HTTP. No authentication is required.
For Claude Code:
claude mcp add dot-tools --transport http https://dot.tools/mcp
The endpoint is hosted and stateless, so there is no local process to install or keep running.
Data handling
MCP tool calls run server-side: the inputs you provide are sent to dot.tools for processing. Our MCP usage telemetry records the request method, tool name, client name/version when provided, and timestamp. This telemetry does not include tool inputs or outputs; records older than 90 days are deleted daily.
