Scope
This page covers the ISO 20022 Navigator MCP server at https://mcp.isonavigator.io/iso20022, which AI assistants use to look up ISO 20022 reference data. It is described on the documentation page. Each ISO Navigator MCP server gets its own section on a page like this one.
What the server receives
When an AI assistant calls the tool, it sends up to two short values:
message: a message identifier such asMT103orpacs.008(up to 40 characters).standard(optional): a standard or scheme name such asSEPA(up to 30 characters).
The server works from these values alone. The rest of the conversation, chat history, files and any account details stay with the assistant and its provider.
What the server records
- One log line per call: the time, the tool name, the two values above, the outcome (found, not found, error or rate limited), the response size and the duration. Error entries also carry technical details of the error.
- Hosting records: as with any web service, the hosting infrastructure handles standard request details such as the time, the path, the status code and network addresses.
The server needs no account or sign-in and sets no cookies.
How long it is kept
Logs are held in the hosting provider's log storage for up to 7 days and are then deleted automatically.
How it is used
- To run the service and diagnose errors.
- To protect the service from overload. The rate limit is a shared counter and holds no per-person data.
- To understand which messages people look up, so the reference data can improve.
Who else handles the data
The server is hosted on Railway, which also stores the logs. The reference data comes from a database hosted on Neon, which holds reference data only. These documentation pages are hosted on Vercel. The values the server receives are not sold or shared for advertising.
A note for people using assistants
Your AI assistant's provider handles your conversation under its own privacy policy. The tool needs only message identifiers, so there is no reason to include personal data in a question to it.
