Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Verified business identity for AI agents: 11.3M entities, EU VAT (VIES), BORME, GLEIF. Free trial.
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.

Tool names and descriptions exactly as the server reported them on Nov 7, 2026. The maker wrote them, not us; we show them as plain text.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 2 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 (4.4.1) reached the registry 19 days ago.

Structured business intelligence for AI agents.
ENTIA gives AI agents verified business identity data from official public registries — accessible via Model Context Protocol (MCP) or REST API.
| Metric | Value |
|---|---|
| Verified entities | 11,330,391 |
| BORME mercantile acts | 40.3M |
| Active sources | 16 |
| MCP tools | 12 |
Reference snapshot / tools verified on 2026-10-14; do not assume the snapshot is updated on every registry recrawl. Query get_platform_stats for current coverage and tools/list for current tool names. An entity registry identifier is not a VIES-confirmed VAT number.
No installation needed. Connect your MCP client directly:
Claude Desktop — add to claude_desktop_config.json:
{
"mcpServers": { "entia": { "command": "npx", "args": ["mcp-remote", "https://mcp.entia.systems/mcp"] } } }
Cursor IDE — add to .cursor/mcp.json:
{
"mcpServers": { "entia": { "command": "npx", "args": ["mcp-remote", "https://mcp.entia.systems/mcp"] } } }
Then try:
Look up Telefonica in Spain
# Search entities
curl "https://entia.systems/v1/search?q=telefonica&country=ES&limit=5" \ -H "X-ENTIA-Key: YOUR_API_KEY"
curl "https://entia.systems/v1/profile/Telefonica?country=ES"

A Python client lives in this repo under entia_mcp/ (wraps a subset of tools as convenience methods). The full 12-tool surface is always available via the hosted endpoint (Option 1). A published PyPI package is planned.

Maintainers of external MCP directories: this GitHub README and glama.json supersede older cards describing *5.5M entities / 34 countries / 20 MCP tools / per-call overage*. Please refresh the existing listing and use the canonical io.github.entia-systems-core/entity-verification registry identity, rather than creating a duplicate. Publisher-side metadata is not proof that a third-party index has refreshed.
