Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Web fetch for agents through your own Proxlane gateway. Block pages come back as failures.
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.

It passed 1 of 1 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.
You need to fill in: PROXLANE_API_KEY
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

An MCP server that gives an AI agent a web-fetch tool that fails honestly.
A plain fetch hands an agent a 200 with a captcha in the body, and the agent summarises the captcha. This tool fetches through your own Proxlane gateway, which fails over between scraping APIs and checks every response for block pages. The agent gets the page as readable text, or a failure that says what happened and whether retrying is worth it. A block page is never returned as content.
You need a running gateway with at least one provider key. That is one container: proxlane.dev/docs/quickstart.
Then add the server to your MCP client. Claude Code:
claude mcp add proxlane --env PROXLANE_URL=http://localhost:8787 --env PROXLANE_API_KEY=your-gateway-key -- npx -y @proxlane/sdk@0.1
Claude Desktop, Cursor and other clients take the same three things in their JSON config:
{
"mcpServers": { "proxlane": { "command": "npx", "args": ["-y", "@proxlane/sdk@0.1"], "env": { "PROXLANE_URL": "http://localhost:8787", "PROXLANE_API_KEY": "your-gateway-key" } } } }
PROXLANE_API_KEY is the gateway's own key, not a provider's. Provider keys stay on the gateway. Pin the version, as above: npx -y otherwise runs whatever was published last, with that key in its environment.
Every call spends provider credits, several times more with render or wait_for. The tool is deliberately not marked read-only, so clients that auto-approve read-only tools still ask.
fetch_page
| Argument | ||
|---|---|---|
url | required | http or https |
render | optional | run JavaScript first; costs several times more |
wait_for | optional | a CSS selector to wait for; implies render, and the page is a failure if it never appears |
country | optional | two-letter code, e.g. us |
format | text (default) or html | |
max_chars | default 20000 | longer results are truncated, and say so |
On failure the result is marked as an error and reads:
{ "ok": false, "outcome": "SOFT_BLOCK", "class": "blocked", "retryable": true, "chain": "scraperapi:SOFT_BLOCK>brightdata:SOFT_BLOCK" }
class is one of six that never grows, and retryable follows from it: the site's own answer (target) and a bad request (client) are not worth retrying; a block or a provider problem may be, later. The gateway has already tried every provider it could, so an immediate retry is not.
