Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Verified web fetch for agents: detects blocks and empty JS pages, falls back, bills only on success.
These three are never merged into one score: opinions, measurements and popularity are different things.

Pick the AI app you use, then copy the settings.
FETCHROUTER_API_KEY, X-API-KeyValues marked secret are keys to your account. Never share them or paste them into a chat.

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.
fetch_pageFetch a public URL and get its content only if it really loaded. Checks for block pages, CAPTCHAs, login walls and empty JavaScript shells, and retries through other routes (including a headless browser) automatically. Billed only on success. Returns markdown by default. If ok is
domain_reliabilityPass rates per route (plain HTTP, browser, providers) for a domain over the last 30 days, from real verified fetches. Use it to choose mode/max_cost before fetching a hard site. Free, no key needed.

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.
You need to fill in: FETCHROUTER_API_KEY, X-API-Key
Either way works: install it on your computer or connect to the cloud version.

MCP server for Fetch Router: web fetch for AI agents that only bills when the page actually loaded.
Agents often get a 200 OK that is really a Cloudflare challenge, a DataDome block or an empty React shell, and then summarise the error page. Fetch Router checks every page for HTTP errors, block and challenge pages (Cloudflare, DataDome, PerimeterX, Akamai, Imperva, Kasada…), login walls, empty JavaScript shells and text you expect to see. If a check fails it retries through another route, such as a headless browser. Failed fetches cost nothing.

Remote (no install). Streamable HTTP at https://fetchrouter.dev/mcp, with your key in a header:
claude mcp add --transport http fetchrouter https://fetchrouter.dev/mcp --header "Authorization: Bearer fr_..."
Other clients: URL https://fetchrouter.dev/mcp, header Authorization: Bearer fr_... (or X-API-Key: fr_...).
Claude Code plugin (MCP server plus a verified-fetch skill; asks for your key once and stores it securely):
claude plugin marketplace add JonnoGit/fetchrouter-mcp
claude plugin install fetchrouter@fetchrouter
Local (stdio via npx).

(url, mode?, expect_text?, expect_selector?, max_cost?): returns markdown (default) or HTML, plus which route delivered it and what was tried. max_cost caps credits: 1 = plain HTTP only, 2 (default) allows a browser. If the page can't be loaded, the error says why (blocked:cloudflare, http_404, expect_text_missing…) and nothing is billed.(domain): pass rate per route for a site over the last 30 days, from real verified fetches. Free, no key needed.A fixed list of 166 public pages in six site types is fetched every night with plain HTTP and with a headless browser, from a datacenter IP.
