Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Live EDC knife, flashlight and fidget prices across retailers, deal checks, top deals and new drops.
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 6, 2026. The maker wrote them, not us; we show them as plain text.
search_productsSearch Drop Beacon's catalog of 150,000+ everyday-carry products (knives, flashlights, fidget sliders and coins, pens, multitools). Returns matching products with brand, the catalog price and the edc4me.com page; models and configurations (steel, color) are separate products. Use
find_offersFor one product, list the retailers that currently have it in stock, with price, configuration (blade steel, color, finish), when Drop Beacon last checked, any coupon, and a tracked buy link. If a name matches several models, the reply says so and lists other_matches. Prices are
deal_checkCompare a product's lowest current in-stock price with the range Drop Beacon has observed (90-day low, all-time low, high, how long it has been watched) and return a plain verdict with a confidence level. Summary only; it does not return the full price history.
top_dealsLive markdowns across the EDC products Drop Beacon tracks: in-stock items priced at least 10% below the seller's own compare-at ("was") price, checked in the last 3 days. Each result has the price, the was-price, percent and dollars off, the lowest price Drop Beacon itself has re
upcomingWhat's new in EDC right now: in-stock products Drop Beacon first saw in the last 7 days, plus Drop Beacon's live giveaways (free to enter) with draw dates and entry links.
get_brand_infoA brand's Drop Beacon profile: page link, official website, whether it is a maker or a retailer, its in-stock product count and any public discount code.

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.
Either way works: install it on your computer or connect to the cloud version.

Read-only EDC product discovery through Drop Beacon's public HTTPS catalog API. No database password, DATABASE_URL, or API key is required.
Drop Beacon also runs a hosted, read-only MCP server at `https://edc4me.com/mcp` (Streamable HTTP, no key). Add it as a custom connector in Claude or ChatGPT, or point any MCP client at the URL. Its tools: search_products, find_offers (live in-stock prices across retailers with buy links), deal_check (today's price against the range Drop Beacon has observed), top_deals (the biggest live markdowns, with a was-price check), upcoming (new drops and free giveaways) and get_brand_info.
Requires Node.js 20 or newer. Configure your MCP client:
{
"mcpServers": { "drop-beacon": { "command": "npx", "args": ["-y", "drop-beacon-mcp@0.3.0"] } } }
| Tool | Public data returned |
|---|---|
search_products | Up to 25 currently available catalog matches |
get_latest_drops | Recent in-stock listings first seen within seven days |
get_brand_info | Public brand profile and available-product count |
check_availability | Up to 10 matching available listings |
Categories: knife, fidget, flashlight, pen, wallet, multi_tool, patch, other. Search arguments accept up to 120 characters. Results are catalog snapshots, not guarantees of current retailer stock. Compare the exact material, configuration and condition on the linked product page. No match does not mean unavailable everywhere. First seen means discovered by Drop Beacon, not released by the manufacturer.
Remove DATABASE_URL and API_KEY from client and hosted-service settings. Upgrade any cached installation to 0.3.0 or newer. If a real database password was ever shared, revoke it with the database provider; editing a listing alone cannot revoke access.
Direct SQL access, arbitrary URLs, private records, and internal market analytics are not supported. get_market_trends and get_price_comparison have been retired from this public MCP; use the market pages and product comparison on the website. The old optional API_KEY gate and legacy SSE endpoints are removed. Do not send credentials as tool arguments.
The package has no database driver and only performs credential-free GET requests to https://edc4me.com/api/drops and /api/brands. Explicit output allowlists prevent new upstream fields from silently becoming MCP output. Requests reject redirects, time out after 15 seconds, cap response bodies at 2 MB, and return generic errors without upstream response bodies. Tool arguments cannot override the origin, endpoint, HTTP method, or headers.
The process allows 60 tool calls per minute, shared across clients and reset on restart; this is a best-effort local limit, not a distributed quota. The public API also applies its own edge protections. A 429 response asks the client to wait, never to supply database access.
Stdio is the default. Optional stateless HTTP uses PORT, binds to loopback by default, and serves POST /mcp plus GET /health. Hosted services can explicitly set HOST=0.0.0.0. Browser origins other than https://edc4me.com are rejected, request bodies are limited to 64 KB, and batched requests are rejected. No customer-specific authentication is needed because only public catalog data is available.
