Connect Claude to TreasuryFlow

MCP setup guide · updated June 2026

TreasuryFlow runs a Model Context Protocol (MCP) server. Connect it and Claude can read your live cash position, 13-week forecast, AR aging, and vendor spend: deterministic numbers, straight from your bank feeds, no copy-paste. Access is read-only: there are no tools that move money, edit transactions, or change anything. Every call is logged to an audit trail you can review.

What Claude can do: read cash, forecast, AR, vendor, and health data scoped to your account. What Claude cannot do: move money, create or edit anything, or see another tenant’s data. The mutate tools don’t exist on the server, so no prompt, however creative, can invoke one.

Mint an API key (Claude Code & Desktop only)

Connecting from claude.ai on the web? Skip this step: you’ll sign in with your TreasuryFlow account when Claude prompts you (OAuth), no key to copy.

In the portal, open Settings → Connected apps & API keys and create a key labeled for the device you’ll connect (for example “Claude desktop”). The key starts with tfmcp_ and is shown once, so store it in a password manager. We keep only a hash. Keys are read-only scoped, rate-limited, and revocable in one click.

The same card lists every app you’ve connected via OAuth (like claude.ai) and every key you’ve minted, each with a one-click revoke, plus the audit trail of everything connected apps accessed on your account.

Add the connector in Claude

The server URL is https://app.treasuryflow.ai/mcp (streamable HTTP). Pick your client:

Claude.ai (web): one click, no key. Go to Settings → Connectors → Add custom connector, paste the URL below, and click Add. When Claude asks you to authorize, sign in with your TreasuryFlow account (email/password or Google) and approve read-only access; that’s the whole flow.

https://app.treasuryflow.ai/mcp

The connection uses OAuth with PKCE: claude.ai never sees a password or an API key, the access it gets is the same read-only scope as everything else on this page, and you can disconnect it any time from Claude’s connector settings.

Claude Code (terminal): one command:

claude mcp add --transport http treasuryflow \ https://app.treasuryflow.ai/mcp \ --header "Authorization: Bearer tfmcp_YOUR_KEY"

Claude Desktop: add this to claude_desktop_config.json (Settings → Developer → Edit Config):

{ "mcpServers": { "treasuryflow": { "command": "npx", "args": [ "mcp-remote", "https://app.treasuryflow.ai/mcp", "--header", "Authorization: Bearer tfmcp_YOUR_KEY" ] } } }

Any other MCP client connects the same two ways: OAuth (discovery starts at the server’s 401 response, dynamic client registration supported) or a bearer Authorization header with a tfmcp_ key.

Ask Claude about your cash

Once connected, Claude sees nine read-only tools. Things people actually ask:

  • “What’s our cash position right now, by company?”
  • “Walk me through the 13-week forecast: where does the balance dip after debt payments?”
  • “Which invoices are 60+ days overdue, and how much is at risk?”
  • “Which vendors crept up this quarter?”
  • For firms: “Which client runs out of cash first?”

Claude drafts the email, the board note, the client brief, with numbers it pulled from the same deterministic engine your dashboard uses, not numbers it guessed.

Read-only, by construction
Every tool declares readOnlyHint and the server ships zero mutate tools. Keys carry a read scope; a future write tool would be rejected for every existing key.
Every call audit-logged
Each tool call writes an audit row: which tool, when, from where, how long. “Show me everything Claude read this month” is one request away.
Revocable & rate-limited
Revoke a key, or disconnect the claude.ai connector, any time; access stops immediately. Per-key and per-account limits (60/min, 1,000/day) keep an over-eager agent from hammering your data.
