Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
200+ pay-per-call APIs for AI agents via x402: on-chain data, DeFi, markets and compliance.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.
Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.
current_dateGet the current date and local time in Europe/Madrid. Free; evaluated live for every call.
search_servicesSearch the Vextorium catalog of 242 paid data services by keywords (e.g. 'crypto price', 'sanctions', 'ECB rates', 'earthquakes'). Free. Returns service ids, descriptions and prices.
service_detailsDetails of one Vextorium service: what it does, its price in USDC, the JSON input it accepts (schema) and an example. Free.
call_serviceRun any Vextorium service with its parameters and get the JSON result. Paid per call in USDC via x402 (price shown by service_details); invalid input or a failed upstream source is not charged.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
The GitHub repo last changed –, and the latest version (1.0.7) reached the registry 2 days ago.
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

200+ pay-per-call APIs for AI agents via x402: on-chain data, DeFi, markets and compliance. Connect over Streamable HTTP and pay in USDC or RLUSD. No sign-up, no API keys, no subscriptions: failed calls are never charged. See the live catalog for the current exact count and available services.

| Tool | Cost | What it does |
|---|---|---|
search_services | free | Search the catalog by keywords ("token safety solana", "ECB rates", "sanctions") |
service_details | free | Inputs (JSON schema), example and price of one service |
call_service | per call (from $0.001) | Run any service and get JSON; paid via x402 in USDC (Base, Solana, Polygon) or RLUSD (XRPL) |
Claude Desktop / Cursor / any MCP client (remote server):
{
"mcpServers": { "vextorium": { "url": "https://api.vextorium.com/mcp" } } }
Paid calls need an x402-capable MCP client or wallet (e.g. AgentCash, Coinbase awal). Without one, search_services and service_details still work.
Plain HTTP works too: every service is POST https://api.vextorium.com/v1/ with a JSON body. The first call returns HTTP 402 with the price; pay and retry.
Only open, redistributable and on-chain data sources. Inputs are processed in memory and not stored. Not financial or legal advice. Terms: https://api.vextorium.com/legal
