Cursor MCP server

Add Prowl to Cursor

Create or merge .cursor/mcp.json in the project — make sure .cursor is git-ignored, since the file holds your key — then reload Cursor:

{
  "mcpServers": {
    "prowl": {
      "url": "https://prowl.chat/mcp",
      "headers": {
        "Authorization": "Bearer prowl_YOUR_KEY_HERE"
      }
    }
  }
}

Generate the key in MCP Home first. Prowl speaks Streamable HTTP at https://prowl.chat/mcp and authenticates with an Authorization: Bearer prowl_<your_key> header.

Add the slash skill as well

Connecting the MCP server exposes the tools but does not create the slash skill. For that, also save the skill file from /mcp/skill.md to .cursor/skills/prowl/SKILL.md for the project, or ~/.cursor/skills/prowl/SKILL.md to have it everywhere.

Faster path: hand the agent the install skill and let it wire itself up — paste “Set up the Prowl MCP using the install skill at https://prowl.chat/mcp/install.md — my token is prowl_YOUR_KEY.”

What this is useful for inside an editor

The agent already has your code. Prowl gives it the market context that is not in the repository:

• Before writing landing copy — check whether the phrase you are about to target has measurable demand, against two independent volume datasets.
• While planning a feature — pull competitors' rankings, ad creatives and review complaints for the same problem.
• During an SEO pass — live SERP positions, keyword difficulty and CPC for the pages you are editing, without switching tools.
• For a full teardown — one prowl_analyze call returns an executive-ready report instead of a pile of raw rows.

Keeping spend visible

Every call debits provider cost times a uniform markup from a prepaid USD wallet and returns a billing object with the exact amount charged, so an agent looping over tools cannot quietly run up a bill. Keys carry optional restrictions: allowed tool categories, daily and total spend caps, and an IP allowlist.

New accounts start with $5 in credit. Rate limits and errors documents the per-key and per-IP ceilings and the backoff an agent should implement; Getting Started covers the first run end to end.
