GetAppNiche

The Model Context Protocol surface of GetAppNiche: live App Store & Google Play data — app discovery with revenue & download data, ASO keyword scoring, historical metrics and review feeds — for Claude, Cursor, Codex, Gemini CLI and any other MCP-capable agent.

You probably don't need to run anything. The server is hosted:

https://api.getappniche.com/mcp        Streamable HTTP · JSON-RPC 2.0
Authorization: Bearer YOUR_API_KEY     app.getappniche.com → Settings → API Keys

Setup per client

Claude Code — one command, no restart:

claude mcp add --transport http getappniche https://api.getappniche.com/mcp \
  --header "Authorization: Bearer YOUR_API_KEY"

Cursor — .cursor/mcp.json (project) or ~/.cursor/mcp.json (global):

{
  "mcpServers": {
    "getappniche": {
      "url": "https://api.getappniche.com/mcp",
      "headers": { "Authorization": "Bearer YOUR_API_KEY" }
    }
  }
}

Claude Desktop — claude_desktop_config.json, then restart the app fully:

{
  "mcpServers": {
    "getappniche": {
      "command": "npx",
      "args": ["-y", "@getappniche/mcp"],
      "env": { "GETAPPNICHE_API_KEY": "YOUR_API_KEY" }
    }
  }
}

VS Code (Copilot agent mode) — .vscode/mcp.json:

{
  "servers": {
    "getappniche": {
      "type": "http",
      "url": "https://api.getappniche.com/mcp",
      "headers": { "Authorization": "Bearer YOUR_API_KEY" }
    }
  }
}

Windsurf — ~/.codeium/windsurf/mcp_config.json (the field is serverUrl):

{
  "mcpServers": {
    "getappniche": {
      "serverUrl": "https://api.getappniche.com/mcp",
      "headers": { "Authorization": "Bearer YOUR_API_KEY" }
    }
  }
}

Codex CLI — ~/.codex/config.toml, then export GETAPPNICHE_API_KEY:

[mcp_servers.getappniche]
url = "https://api.getappniche.com/mcp"
bearer_token_env_var = "GETAPPNICHE_API_KEY"

Gemini CLI — ~/.gemini/settings.json (the field is httpUrl):

{
  "mcpServers": {
    "getappniche": {
      "httpUrl": "https://api.getappniche.com/mcp",
      "headers": { "Authorization": "Bearer YOUR_API_KEY" }
    }
  }
}

Zed, Cline, Continue and JetBrains AI are covered too — getappniche.com/mcp has every snippet. Companion agent skills: getappniche/aso-skills (npx skills add getappniche/aso-skills).

ChatGPT — Settings → Connectors → create a custom connector (Developer mode), point it at https://api.getappniche.com/mcp and pick API key authentication, then paste your key.

claude.ai on the web documents request-header auth, but its connector UI currently exposes only OAuth fields — until that settles, use one of the clients above.

What's in this repo

A zero-dependency stdio bridge for clients that speak MCP over stdio and can't send HTTP headers — in two flavours: bin/cli.mjs (Node 18+, published as @getappniche/mcp) and server.py (Python 3.9+, stdlib only). Both forward every JSON-RPC message to the hosted endpoint over TLS and stream responses back.

# Node — one-liner, no install
GETAPPNICHE_API_KEY="getappniche_..." npx -y @getappniche/mcp

# Python — no dependencies
GETAPPNICHE_API_KEY="getappniche_..." python3 server.py

Claude Desktop (claude_desktop_config.json):

{
  "mcpServers": {
    "getappniche": {
      "command": "npx",
      "args": ["-y", "@getappniche/mcp"],
      "env": { "GETAPPNICHE_API_KEY": "getappniche_..." }
    }
  }
}

server.json is the manifest published to the official MCP registry as com.getappniche/mcp.

Being ~150 readable lines, it doubles as a reference for what travels over the wire: your API key goes only into the Authorization header of TLS requests to api.getappniche.com — nothing else, nowhere else.

Tools

• search_apps - Search apps across 25+ filters: store, categories, languages, price model, rating, reviews, downloads, revenue, release and update recency, review growth - sorted by any column (1 credit)
• get_app_detail - Get one app by canonical id, bare Apple id, Android package name, or a pasted store URL (1 credit)
• get_app_historicals - Metric time series: reviews, ratings, downloads, revenue (1 credit)
• get_keyword_difficulty - Popularity, difficulty, traffic and opportunity for a keyword (10 credits)
• batch_keyword_difficulty - Score up to 10 keywords, sorted by opportunity (10 credits per keyword)
• get_app_reviews - Live App Store or Google Play reviews for any app by id, package name or URL, or enriched rows for apps monitored in your workspace (1 credit)
• get_supported_countries - List valid store country codes (free)

Credits ship with a GetAppNiche plan (Pro: 5,000/month) and every result reports credits_charged. Rate limit: 60 requests/minute per key.

Protocol notes

• Methods: initialize → notifications/initialized → tools/list / tools/call. Protocol errors use standard JSON-RPC codes; tool-level errors (bad id, out of credits) come back as tool results your agent can read.
• The bridge honours Mcp-Session-Id and accepts both JSON and SSE-framed responses.
• OAuth for clients whose connector UI can't set headers (claude.ai web) is in progress; ChatGPT connects today with API-key auth.
