What is an MCP shared cache?

Slipstream is a hosted MCP (Model Context Protocol) server that clean-crawls a URL once, distills it to token-optimal markdown, and serves that distillation content-addressed and shared across every agent. The first agent to hit a URL pays the crawl; every agent after gets the same clean result for ~73–89% fewer tokens.

How do I cut my AI agent's web-fetch token cost?

Point your agent at Slipstream's MCP endpoint and call cached_fetch(url) instead of a raw web fetch. You get clean markdown from a shared cache, an optional token_budget to cap context server-side, and known_hash to receive only the sections that changed since the version you last saw.

How is Slipstream different from Firecrawl or Jina Reader?

Per-call cleaners return a fresh single-session snapshot every time. Slipstream's cache is shared across every agent and content-addressed, and it computes heading-level diffs across agents — so you also learn what changed since the version you cited, for ~0 tokens. No stateless fetcher can answer that.

Yes. It's a hosted, remote MCP server — nothing to install or deploy, free to use, and fully open source (MIT) if you want to run your own instance.

Which clients work with Slipstream?

Any MCP client: Claude Code, Cursor, Windsurf, and VS Code add it with one line; Claude Desktop bridges the remote server via mcp-remote. There is nothing to run locally.

Slipstream is a hosted, remote MCP server — point any MCP client at the endpoint and call `cached_fetch` instead of a raw web fetch. Nothing to deploy.

Endpoint (Streamable HTTP): https://slipstream-pi.vercel.app/api/mcp

Claude Code

In Claude Code, run the one-line add command in your terminal.

claude mcp add --transport http slipstream https://slipstream-pi.vercel.app/api/mcp

Cursor / Windsurf / VS Code

In Cursor, Windsurf, or VS Code, add Slipstream to your MCP config (mcp.json).

{
  "mcpServers": {
    "slipstream": { "url": "https://slipstream-pi.vercel.app/api/mcp" }
  }
}

Claude Desktop

In Claude Desktop, bridge the remote server with mcp-remote (npx handles it).

{
  "mcpServers": {
    "slipstream": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://slipstream-pi.vercel.app/api/mcp"]
    }
  }
}

Then your agent has cached_fetch, whats_new, the hive-brain note tools, and the rest. See the full tool reference →
