Netcafe Devkit is an MCP server with 14 tools an agent can call, among them diff_text, json_format, json_yaml. It answers at https://ainetcafe.com/mcp/dev?s=registry over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 10 of 11 times since 4 September 2026; the last check, on 7 November 2026, succeeded.
JSON/YAML, regex, diff, JWT, SQL dialects — the keyless millisecond ops an agent needs mid-task.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
diff_text | Returns which lines were added and which were removed, with line numbers — computed with a longest-common-subsequence, not guessed by a model. Use to compare two versions of a config, a document, or any command output, instead of asking an Inputs: a, b |
json_format | Validate and pretty-print JSON (2-space indent). Reports the error location if invalid. Inputs: json, url, indent |
json_yaml | Converts JSON to YAML or YAML to JSON. It works out which one you gave it, so you do not have to say. A parse failure comes back with the parser message instead of silently producing something that looks fine and is not. Use when a config, Inputs: text, to |
jwt_decode | Decodes the header and payload of a JWT and reports issued-at / expiry as readable timestamps plus seconds remaining. The signature is NOT verified and the response says so — decoding is fine for debugging a token you already hold, but neve Inputs: token |
make_qr | Any text or URL → a QR code PNG you can embed or download. Stateless URL form: https://ainetcafe.com/i/qr/<text> Inputs: text |
redact_text | Strip emails, phone numbers, ID numbers, API keys, private keys, JWTs, card numbers and IPs out of text, returning the redacted text plus a mapping table to restore them afterwards. Rule-based only — no model sees the input. The same value Inputs: text, only |
regex_test | Runs a regular expression against sample text and returns every match with its position and capture groups (named groups included). Use before wiring a pattern into code, instead of guessing whether the escaping survived the trip through JS Inputs: pattern, text, flags |
screenshot_url | Full-page screenshot of any URL → PNG. The same job screenshot APIs charge $7-79/month for. Inputs: url, width |
sql_from_description | Plain-language request + table schema → ready-to-run .sql file with comments. Inputs: request, schema, dialect |
timezone_convert | Convert a time between time zones, or get current time in any zone. from/to = IANA zone (Asia/Shanghai), time = YYYY-MM-DDTHH:mm (default now). Inputs: to, from, time |
transpile_sql | Convert a SQL statement from one dialect to another — mysql, postgres, sqlite, tsql, oracle, snowflake, bigquery, redshift, spark, hive, presto, trino, duckdb, clickhouse, databricks, doris, starrocks and more. Deterministic parser (sqlglot Inputs: sql, read, write |
unit_convert | Convert units: length, weight, temperature, area, volume, speed, data size. value + from + to (e.g. 100 km mi, 25 c f). Inputs: value, from, to |
validate_json | Checks that text parses as JSON, and optionally that required keys are present with the right top-level types. Returns the specific violations, not just true/false. Checks required + types only — not full JSON Schema, and it says so rather Inputs: text, schema |
what_can_you_do | Describe a task in plain language (any language) and get back exactly which tools on this server do it, with ready-to-run example calls — instead of reading the whole catalogue and guessing. Also returns multi-step recipes when a task needs Inputs: task |

It answered our last check on 7 November 2026 in 1425 ms. Over 11 checks since 4 September 2026 it answered 10. Status here comes from Neuronto's own probes, not from the publisher.
Yes. It is published by ainetcafe.com and served from ainetcafe.com, the vendor's own domain: https://ainetcafe.com/mcp/dev?s=registry.
14, as returned by the server's own tools/list on 9 September 2026: diff_text, json_format, json_yaml, jwt_decode, make_qr, redact_text, regex_test, screenshot_url, and 6 more.

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://ainetcafe.com/mcp/dev?s=registry. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.

First indexed 31 August 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
