tokyn.trail
An MCP server gives an agent real power to act: place orders, change records, send messages. tokyn.trail puts a control layer in front of it — every tool call is recorded, critical actions need an approval, and the evidence survives any review.
The agent can do anything — and nobody can prove what it did.
The moment an agent gets tools, the question shifts from “what does it answer?” to “what does it do?”. In development that is wonderful. Once money, contracts or customer data are involved, two things are missing: a brake in front of the critical action, and a record that holds up when someone wants to know exactly what happened. That is the gap trail closes — without rebuilding your MCP server.
Control, without slowing the agent down.
complete tool-call log
Every call is written down — parameters, timestamp, result. Not a sample, the full record.
rule-based approvals
You define which actions need a human yes. Everything else passes through uninterrupted.
tamper-evident hash chain
Entries are linked into a chain. Later edits to the log show up instead of going unnoticed.
approvals by email or slack
Decisions happen where people already work — no extra tool anyone has to open daily.
monitor mode
Record first without blocking. See what the agent actually does, then sharpen the rules.
Anywhere an agent does more than talk.
trail pays off as soon as an agent triggers actions somebody has to answer for. Typical fields:
- E-commerce — orders, refunds, price changes.
- SaaS — changes to customer accounts and permissions.
- Finance and accounting — payments, bookings, approval limits.
- Internal operations — anything that writes back into a business system.
Monitor mode is free: record, see what happens, decide afterwards. If you are earlier than that and still wondering where agents make sense at all, have a look at our work on AI agents.
