Available tools 32

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

generate

generate-avatar

Create an SVG placeholder profile icon. Use for synthetic avatars in demos and UI prototypes. Returns SVG markup, not a photorealistic likeness.

generate-card-number

Generate a synthetic payment-card fixture. Use for payment-form UI tests requiring a Luhn-valid card number. Returns {number, brand, expiry, cvc}; values are synthetic, not issued credentials.

generate-color

Generate a palette from a base color and harmony scheme. Use for design prototypes; defaults: random base, triadic scheme, five hex colors. Returns {base, scheme, colors, textOnBase}; text color is heuristic, not a WCAG contrast check.

generate-dataset

Generate synthetic rows as JSON, JSONL or CSV. Use for data import/export tests; use generate-fake-data for preset people or company fixtures. Returns at most eight records without accessing a database.

generate-fake-data

Create fictional users, companies, addresses or rows. Use to seed demos with preset records; use generate-dataset for custom fields. Synthetic values are not verified identities.

generate-hash

Compute SHA-256 or legacy MD5 text digests. Use for non-secret content fingerprints; generate-token creates new IDs instead. Returns a hex digest; unsuitable for password storage or key derivation.

generate-lorem

Generate lorem ipsum placeholder copy. Use for mock layouts needing filler words, sentences or paragraphs. Returns synthetic copy, not sourced editorial content.

generate-password

Generate random or seeded test passwords. Use for demo login fields; use generate-token for identifiers. Seeded values are predictable and visible to MCP clients; not a secure credential vault.

generate-phone-number

Generate fictional US-format phone numbers. Use for US demo phone fields; when supplied, city selects a local area-code pool and must match state. Returns an array of fictional (AAA) 555-01XX numbers; no subscriber lookup.

generate-prompt

Fill a prompt template with supplied variables. Use {name} placeholders with matching vars.name; missing variables become empty text. Returns a prompt string without invoking a model; code/image modes can add framing.

generate-slug

Convert a title into a Unicode-aware URL slug. Use when forming new path segments from headings. Inspect output before publishing permanent URLs.

generate-ssn

Generate fictional US SSN-style test identifiers. Use for SSN test fields; use generate-fake-data for mixed-record fixtures. Returns a string for count=1, otherwise an array; structural validity does not confirm issuance.

generate-token

Generate token strings or UUIDs. Use for test identifiers; use generate-password for password fixtures. Seeded output is predictable and unsuitable for authentication credentials.

minify

minify-css

Reduce whitespace in CSS snippets. Use for basic stylesheet cleanup rather than production minification. Not a full CSS parser; visually test the result.

minify-html

Remove comments and compact whitespace in HTML fragments. Use for small, controlled HTML snippets, not full document compilation. Returns an HTML string; preserves pre, textarea, script and style contents. Regression-test rendered output.

minify-js

Compact small JavaScript snippets. Use for basic source cleanup, not AST-aware production minification. Returns JavaScript text, sometimes unchanged for complex syntax; regression-test its behavior.

minify-prompt

Normalize prompt whitespace and line breaks. Use to compact formatting before calling a model; filler phrases are not removed. Returns trimmed text with normalized spacing; review prompts where whitespace carries meaning.

optimize

optimize-dataset

Clean and compact JSON, JSONL or CSV rows. Use for small datasets; use is-json-safe to check JSON syntax without changes. Returns text in the selected format; trims strings, deduplicates rows and may drop mostly empty columns.

optimize-google-tag

Rebuild GA4 gtag.js markup from a G- measurement ID. Use on existing GA4 snippets, not GTM containers or consent setup. Returns replacement HTML with async loading and a config call, or original input if no G- ID exists. Review lost settings and consent.

card

is-card-safe

Check payment-card brand, length and Luhn checksum. Use with synthetic card numbers in payment-form tests. Returns {ok, normalized?, brand?, last4?, issues}; not a payment authorization or fraud check.

is-email-safe

Check conservative ASCII email address syntax. Use to reject malformed addresses in forms and test fixtures. Returns true or false; does not check mailbox existence or deliverability.

iban

is-iban-safe

Check IBAN country rules, length and checksum against a bundled registry. Use to screen public or synthetic IBANs in test data. Returns {ok, normalized?, issues}; does not verify account ownership or transferability.

iso

is-iso-date-safe

Check Gregorian YYYY-MM-DD calendar dates, including leap days. Use for date-only form fields, not timestamps or timezone offsets. Returns true for a valid date, otherwise false.

json

is-json-safe

Parse JSON with bounded depth, key counts and input size. Use to screen JSON without execution; use optimize-dataset for JSONL or CSV cleanup. Returns {ok, issues, bytes, depth, keys, value?}; parsed value is included only when valid.

password

is-password-safe

Evaluate password strength using local heuristics. Use only with dummy passwords when testing password policies. Returns {ok, score, entropyBits, length, sets, reasons, suggestions}; no breach-database lookup.

phone

is-phone-e164

Check phone number syntax against E.164 after local normalization. Use to test international number formats, including spaces or 00 prefixes. Returns true or false, not the normalized number; no subscriber or reachability check.

safe

is-ip-safe

Check IPv4 or IPv6 literal-address syntax. Use to screen candidate IP strings, not test reachability or geolocation. Returns {ok, version, issues}; version is 4, 6 or null.

strip

strip-ansi

Strip terminal ANSI escape codes from text. Use to make colorized logs readable for indexing or display. Returns plain text without interpreting log entries.

tin

is-us-tin-safe

Check synthetic US EIN, SSN or ITIN number formats. Use with tax-ID input fixtures, never real personal identifiers. Returns {ok, normalized?, type, issues}; does not verify IRS issuance or identity.

url

is-url-safe

Check absolute HTTP or HTTPS URL syntax. Use to screen links before display or storage. Returns true or false; does not visit or assess the site's safety.

uuid

is-uuid-safe

Check canonical UUID syntax and optional RFC variant/version. Use to validate UUIDs; use generate-token to create them. Returns true or false; does not check uniqueness or resource existence.

vat

is-vat-safe

Check country-specific VAT number patterns. Use to screen VAT fixtures before form submission. Returns {ok, country?, normalized?, issues}; no VIES lookup or active-registration check.

Agent Tools MCP — questions

Answers built from our own checks of this server.

What can Agent Tools MCP do?

It exposes 32 tools, read directly from the server on our last check. Among them: generate-avatar, generate-card-number, generate-color, generate-dataset, generate-fake-data, generate-hash and 26 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

What is Agent Tools MCP mostly used for?

Its tools cluster around generate, minify and optimize. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is Agent Tools MCP working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 336 ms. The bar chart above shows every period we have measured.

Did Agent Tools MCP ever remove tools?

Yes. is-dataset-minify, is-google-tag, is-html-minify, is-minify-css and 3 more are no longer exposed — we recorded the date each one disappeared. A tool vanishing usually means a breaking change for anything that depended on it.

How do I connect Agent Tools MCP?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Agent Tools MCP need an API key?

No. Agent Tools MCP completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 32 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Agent Tools MCP?

It answers our handshake in 336 ms on average, which is faster than 48% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is Agent Tools MCP open source?

We cannot say either way: written in JavaScript, 0 stars on GitHub and 1 open issue, but we could not determine the licence, and without one the code is not open source by default.
