Type: Application (proxy) | PCID required: Yes Application servers are proxies to external integrations. Each server wraps a third-party API (Slack, Salesforce, Google Sheets, etc.) and exposes it as a set of MCP tools.

​
How Application Servers Work

  1. Connect — Set up a connection in the Pinkfish dashboard to get a PCID (PinkConnect connection ID)
  2. Discover — Call tools/list on the server, or use capabilities_discover and capability_details to find available tools
  3. Call — Invoke any tool using the standard JSON-RPC 2.0 pattern, passing the PCID in the request
For full details on setting up connections and obtaining PCIDs, see the Connections guide.

​
Generic Call Pattern

Every application server follows the same calling pattern. Replace <server-path>, <PCID>, and <tool_name> with your values: 
curl -s -X POST "https://mcp.pinkfish.ai/<server-path>" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer <API_KEY>" \
  -d '{
    "jsonrpc": "2.0",
    "id": 1,
    "method": "tools/call",
    "params": {
      "name": "<tool_name>",
      "arguments": {
        "PCID": "<your-pcid>",
        ...
      }
    }
  }'

​
Discovering Tools at Runtime

Tool schemas for application servers are provided dynamically by the proxy layer and may change as integrations update. Use runtime discovery instead of static documentation: 
# List all tools on a server
curl -s -X POST "https://mcp.pinkfish.ai/<server-path>" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer <API_KEY>" \
  -d '{
    "jsonrpc": "2.0",
    "id": 1,
    "method": "tools/list",
    "params": {}
  }'
Or use the discovery tools on the Pinkfish Workflow Building server (/pinkfish-sidekick): 
# Find tools by describing what you want to do
curl -s -X POST "https://mcp.pinkfish.ai/pinkfish-sidekick" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer <API_KEY>" \
  -d '{
    "jsonrpc": "2.0",
    "id": 1,
    "method": "tools/call",
    "params": {
      "name": "capability_details",
      "arguments": {
        "tool_names": ["slack_send_message", "slack_list_channels"]
      }
    }
  }'
