A real session: Claude Code × Parley

Unedited tool traffic from a headless Claude Code run (claude-sonnet-5), driving the example services through the Parley MCP bridge (parley mcp). The model got no Parley documentation. It had only the bridge's four tool descriptions and the service briefs.

Setup: parley init, then parley grant --risk low --per 40USD --spend 100USD --exp 2h, then node examples/serve.ts, then claude -p "…" --mcp-config …

Prompt: "Move my 1:1 with Ana to a free slot on 2026-09-27. Then order me 4 vegan meals under 700 calories for delivery on 2026-09-26 (2 each of two different meals). Report exactly what happened."

Claude's final answer

The 1:1 with Ana is moved, but the meal order is not placed. The shop blocked it pending your approval, so nothing has been charged.

1:1 with Ana: done

• I moved the event e2 from 2026-09-25 14:00 UTC to 2026-09-27 09:30 UTC. That was the first free slot on the 27th. You didn't specify a time, so tell me if you'd rather have another slot.
• Ana (ana.ruiz@acme.co) was sent an updated invite.
• It was the only event titled "1:1 with Ana". I didn't touch "Design review" or "Pipeline sync with Ana" (a different Ana, ana.li@acme.co).
• Receipt r_OMx81dAk can undo the move until 2026-09-25 02:11 UTC.

Meal order: blocked, waiting on you

• I chose 2× Tofu Pad Thai (light) at 578 cal and 2× Chickpea Shawarma (light) at 622 cal. You didn't name meals, so I took the cheapest non-family vegan pair under 700 cal.
• The total is $53.95 on card ••4242 ($47.96 meals plus $5.99 delivery), for delivery on 2026-09-26.
• When I tried to commit it (proposal p_71KbTFLA), it failed with consent_required. The order exceeds the per-commit limit of $40.00, and you have to approve that exact proposal.
• I didn't try to get around the limit. Splitting it into two orders would have dodged the check. Even the cheapest four meals come to $53.95, so no single order fits under $40.

To go ahead, run this yourself:

parley approve u-1LZPPEeEQe5oTm9EgbKym_LD3xIN_txj4svVpIkbg --expires 1790216520

Then tell me and I'll commit it. The proposal expires 2026-09-24 02:22 UTC, so if that passes I'll re-create it. Once placed, the order can be cancelled for 2 hours.
