Swiss-army-knife utility MCP server for AI agents. 18 tools for JSON validation/formatting, base64 encode/decode, hash generation, UUID generation, URL parsing, regex testing, markdown↔HTML conversion, text stats, slug generation, datetime conversion, cron parsing, text diffing, CSV↔JSON conversion, and JWT decoding. Zero API Key required
Provides deterministic micro-utilities as an MCP server, including free tools for conversion, text processing, hashing, encoding, ID generation, and regex, plus paid per-call tools for timezone, cron, RRULE, currency, diff, JSON Schema validation, and date math.
Enables AI agents to perform exact, reproducible mechanical computation — text diffing, hashing, JSON querying, calendar arithmetic, deadline-bounded regex extraction, CSV parsing, similarity scoring, unit and base conversion — instead of relying on probabilistic guessing. Runs dependency-free, read-only and offline over stdio, with schema validation and hard caps on every operation so no call can hang the client.
Exposes 24 deterministic developer utilities as MCP tools — encoders and hashers, UUID/ULID and timestamp helpers, color, CSS, cron and permission converters, JSON/YAML/XML/SQL/TypeScript transformers, and a web page-to-markdown fetcher. Runs locally over stdio so agents get byte-exact results instead of approximating computations, with only the markdown fetcher making network requests.
