GetAppNiche MCP — App Store & Google Play intelligence for AI agents

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 2.0Authorization: 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-com/aso-skills (npx skills add getappniche-com/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 installGETAPPNICHE_API_KEY="getappniche_..." npx -y @getappniche/mcp
# Python — no dependenciesGETAPPNICHE_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 per app returned, 50 a call by default, up to 100)
• 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 per review returned, 50 a call by default, up to 100)
• 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.
