Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Descripción del creador (original en inglés)
Validate emails, phones, IBAN, VAT; look up IPs and companies; rates, holidays, time via Abstract.
Estos tres nunca se combinan en una sola puntuación: las opiniones, las mediciones y la popularidad son cosas distintas.
Todavía no escribimos un resumen sencillo para este. Abajo están los datos que leímos del registro.

Nombres y descripciones de las herramientas tal como los informó el servidor el 6 nov 2026. Los escribió el creador, no nosotros; los mostramos como texto sin formato.
abstractapi_validate_emailCheck one email address: deliverability (format, MX, SMTP), quality score, free/disposable/role/catch-all flags, sender details and known data breaches. Email Reputation API. Spends 1 credit of your Email Reputation plan per request (a failed request counts too); needs the Email
abstractapi_lookup_phoneValidate and enrich one phone number: format, carrier, line type (mobile, landline, VoIP), location, line status, risk and known breaches. Phone Intelligence API. Spends 1 credit of your Phone Intelligence plan per request (a failed request counts too); needs the Phone Intelligen
abstractapi_lookup_ipGeolocation and security intelligence for one IPv4 or IPv6 address: VPN/proxy/Tor/hosting/abuse flags, ASN, company, location, timezone, flag and currency. IP Intelligence API. An explicit ip_address is required (without one Abstract would look up the caller's own address, which
abstractapi_enrich_companyFirmographic data for a company web domain: name, description, logo, address, industry (SIC/NAICS), employee and revenue ranges, contacts, social profiles, technologies. Company Enrichment API. Spends 1 credit of your Company Enrichment plan per request (a failed request counts t
abstractapi_validate_ibanCheck the structure and check digits of one International Bank Account Number. It does not prove that the account exists. IBAN Validation API. Spends 1 credit of your IBAN Validation plan per request (a failed request counts too); needs the IBAN Validation API key.
abstractapi_validate_vatCheck whether a VAT number is valid and, if it is, return the registered company name and address. VAT Validation API. Spends 1 credit of your VAT Validation plan per request (a failed request counts too); needs the VAT Validation API key.
abstractapi_calculate_vatWork out the VAT-compliant price for an amount in a country: the amounts without and with VAT, the VAT amount and the rate. Set is_vat_incl to true for the reverse calculation (the amount already contains VAT). VAT Validation API. Spends 1 credit of your VAT Validation plan per r
abstractapi_list_vat_ratesThe latest VAT rates of one country: the standard rate and each reduced-rate category with its description. VAT Validation API. Abstract answers this endpoint without checking the key and may not count it as a credit; this tool still needs the VAT API key.
abstractapi_get_exchange_ratesLatest foreign-exchange and cryptocurrency rates for a base currency against one or more targets (all supported currencies if none is given). Exchange Rates API. Spends 1 credit of your Exchange Rates plan per request (a failed request counts too); needs the Exchange Rates API ke
abstractapi_convert_currencyConvert an amount from a base currency to one target currency, at the latest rate or at the rate of a past date. Exchange Rates API. Spends 1 credit of your Exchange Rates plan per request (a failed request counts too); needs the Exchange Rates API key.
abstractapi_get_historical_ratesExchange rates of a base currency on a past date. Abstract lists this endpoint as closed beta: a key may be refused (HTTP 401/403) until Abstract enables it. Exchange Rates API. Spends 1 credit of your Exchange Rates plan per request (a failed request counts too); needs the Excha
abstractapi_get_holidaysPublic, local and religious holidays of a country for a date, a month or a year. Free Abstract plans require year, month and day together; paid plans default missing values to today. Public Holidays API. Spends 1 credit of your Public Holidays plan per request (a failed request c
abstractapi_get_current_timeThe current local date, time and timezone (name, abbreviation, GMT offset, daylight saving) of a place, coordinates or IP address. Timezone API. Spends 1 credit of your Timezone plan per request (a failed request counts too); needs the Timezone API key.
abstractapi_convert_timeConvert a date and time from one location to another (places, coordinates or IP addresses). Without base_datetime the current time is converted. Timezone API. Spends 1 credit of your Timezone plan per request (a failed request counts too); needs the Timezone API key.

Comparado con todos los servidores activos de esta categoría en el registro. Las estrellas solo cuentan cuando quien lo publica es dueño del repo.
Superó 3 de 3 revisiones básicas aplicables. No hemos leído el código. Antes de agregar una clave o un token, revisa qué acceso pide el servidor y usa una clave que tenga solo los permisos que necesitas.
El registro no indica ninguna clave obligatoria, aunque algunos servidores te piden iniciar sesión la primera vez que los usas.
Se ejecuta en la nube del creador. Te conectas por internet sin instalar nada, pero lo que envías pasa por los servidores del creador.
El repo de GitHub cambió por última vez –, y la última versión (1.22.3) llegó al registro ayer.
Las apps compatibles con MCP, como Claude Desktop, Claude Code, Cursor y VS Code. Se conecta por URL, así que también funcionan las apps que aceptan servidores MCP remotos, como ChatGPT en modo desarrollador.

Use Abstract API from Claude, Cursor, or any MCP client — email validation, phone lookup, IP geolocation, company enrichment, IBAN and VAT validation, VAT rates and calculation, exchange rates (live, conversion, historical), public holidays and time zones. Connect with the keys of the Abstract APIs you use (at least one); every call spends credits from your own plan. Hosted, no local install: connect with your own Abstract API credentials.
Live endpoint: https://abstract-api.usefulapi.io/mcp · Homepage: https://usefulapi.io/abstract-api
https://abstract-api.usefulapi.io/mcp.claude mcp add --transport http abstract-api https://abstract-api.usefulapi.io/mcp, then run /mcp to log in.{
"mcpServers": { "abstract-api": { "url": "https://abstract-api.usefulapi.io/mcp" } } }
Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Abstract API credentials.

read tools are read-only; write tools mutate data (clients should confirm them); meta tools report usage, manage your subscription or send a feature request.
| Plan | Price | Limit |
|---|---|---|
| Free | $0 | 50 tool calls / month |
| Pro (per user) | $9/mo or $90/yr (2 months free) | Unlimited* |
\*Pro has a fair use limit of 10,000 tool calls a month on this server. For more, write to support@usefulapi.io.
Pro covers this server only. Subscribe with abstractapi_upgrade (it returns a Stripe Checkout link). Cancel any time with abstractapi_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running abstractapi_upgrade before then undoes the cancel. Or write to support@usefulapi.io.
