GetAppNiche

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

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:

ChatGPT— Settings → Connectors → create a custom connector (Developer mode), point it athttps://api.getappniche.com/mcpand pickAPI keyauthentication, 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.

# 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):

Being ~150 readable lines, it doubles as areference for what travels over the wire: your API key goes only into theAuthorizationheader of TLS requests toapi.getappniche.com— nothing else, nowhere else.

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

- 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 honoursMcp-Session-Idand 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.
