Prerequisites

See the full setup instructions baked into the connector (visible in the in-app store when you select the connector). The required environment variables for this connector are:

KASHFLOW_USERNAME, KASHFLOW_PASSWORD

Step 1 — Get credentials

This connector wraps the KashFlow REST API (securedwebapp.com/api).

Setup:

  1. Log into https://securedwebapp.comSettings → API → Enable API access.
  2. Note your Username + API password (separate from your login password).
  3. Set KASHFLOW_USERNAME and KASHFLOW_PASSWORD.

Authentication: KashFlow uses a REST API with username + password in the URL path: /api/v2/{username}/{password}/<endpoint>. The adapter substitutes both via runtime envVars — the credentials never appear in query string or body.

…(continued in the in-app connector instructions)

Step 2 — Install the adapter

git clone https://github.com/HelpCode-ai/anythingmcp.git
cd anythingmcp && docker compose up -d

Step 3 — Add the connector in ChatGPT

ChatGPT supports MCP servers via the Connectors feature (Plus / Pro / Team / Enterprise plans). The free tier does not support custom connectors.

  1. Open ChatGPT → Settings → Connectors (or click the 🔧 icon in the composer → Manage connectors).
  2. Click "Add custom connector".
  3. Fill in:
    • Name: KashFlow
    • MCP server URL: https://cloud.anythingmcp.com/mcp
    • Authentication: Bearer token → paste your MCP API key (from AnythingMCP → Profile → MCP API Keys → New Key)
  4. Click Connect to authorize.
