Common questions
Is Aethelgard Ledger safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).
Is it still maintained?
The GitHub repo last changed –, and the latest version (0.1.1) reached the registry 29 days ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need MCPB on your computer.

Aethelgard Ledger
A double-entry, multi-entity, tamper-evident ledger for AI agents.
Aethelgard Ledger is a local Model Context Protocol server. It gives your agent real accounting tools backed by an engine that enforces accounting rules. The agent can't talk its way past them. It is the same engine that runs the Aethelgard desktop ledger.
Evaluation build, for business use only. Licensed under the Aethelgard Ledger Evaluation Licence. The ledger file is not encrypted, and output must not be relied on without independent verification.
What it does
- Balanced journals or nothing. Every posting must balance. If debits don't equal credits, the engine rejects the posting and returns the reason, so the agent can't book it.
- Multi-entity. Companies, trusts and individuals across 9 jurisdictions, with subsidiaries linked to a parent and a combined group trial balance. This is a straight sum by account code, not a full consolidation; eliminations live in the Aethelgard desktop app.
- Tamper-evident. Every posting is linked into a per-entity SHA-256 hash-chain, so an entry edited outside the engine fails the integrity check. The chain is unkeyed. For independent assurance, record the latest chain hash (returned by
verify_integrity) somewhere outside the ledger and compare it later. - Local. The ledger lives in a file on your machine and is never sent to us.

Quick start
- Unzip it and put
aethelgard-mcpsomewhere permanent. Check it runs:aethelgard-mcp --version. - Add it to your MCP client as a local (stdio) server.
Claude Code
claude mcp add aethelgard-ledger -- /full/path/to/aethelgard-mcpClaude Desktop, Cursor and other clients
{"mcpServers": { "aethelgard-ledger": { "command": "/full/path/to/aethelgard-mcp" } } }
On Windows, use the path to `aethelgard-mcp.exe` with doubled backslashes, e.g. `"C:\\Tools\\aethelgard-mcp.exe"`.- Ask your agent to keep some books. For example: *"Create PropCo Ltd (GBP, GB, UkLtd) with a bank and a rental income account, then post October's £1,500 rent."*
Where the ledger is kept
| Platform | Default location |
|---|---|
| Windows | %APPDATA%\Aethelgard Ledger |
| macOS | ~/Library/Application Support/Aethelgard Ledger |
| Linux | ~/.local/share/aethelgard-ledger |
To keep it somewhere else, use --vault or set AETHELGARD_LEDGER_VAULT. Use --ephemeral for a throwaway ledger that is deleted when the server stops. Run aethelgard-mcp --help for every option.
Your data
The server runs on your machine and does not send your ledger to us. There is no telemetry. Your MCP client and the AI model you connect see whatever the tools return, such as balances and transactions, under that provider's terms. Choose them accordingly.
