AgentLedger does not always answer

Over the last week it answered 88.2% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

Available tools 7

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

ledger

ledger_alerts

Alert history for an agent: budget warnings (80% threshold) and spending spikes.

ledger_api_docs

Self-serve documentation for AgentLedger — quickstart, MCP tools, REST endpoints, budget caps, error codes, and idempotency usage, as markdown.

ledger_examples

Complete, runnable Python recipe for a common AgentLedger integration pattern.

ledger_list_agents

Owner-only: full cross-tenant listing of every agent ever claimed on this instance, with totals. Requires the operator's admin_secret — this is a portfolio-wide view, not a per-agent report (use ledger_report for that, which needs no secret).

ledger_report

Spend report for an agent over a rolling window. Returns total spend, breakdown by rail and by service, budget status (ok/warning/exceeded), detected anomalies, and entry count.

ledger_set_budget

Set spending caps for an agent. Warns at 80%, blocks spend when exceeded — enforced: a ledger_track call that would cross the cap is rejected. Dollar caps (monthly_cents/daily_cents) and token caps (monthly_tokens/ daily_tokens) are independent dimensions: dollar caps only cover non-"tokens" rails, token caps only cover rail="tokens" bookkeeping rows (tokens_in/tokens_out). Set both if the agent uses both. Monthly cap is required; the rest are optional (0 = no limit). Overwrites any existing budget for the agent. No signup: the first call for a new agent_id mints an agent_secret (returned once — save it); later calls for that agent_id must pass it back.

ledger_track

Record a spend entry for an AI agent on any payment rail, with optional token counts. No signup: the first call for a new agent_id mints an agent_secret and returns it in the response — save it, every later call for that same agent_id must pass it back or the write is rejected. Amounts are capped at $100,000/entry and must be >= 0. If a budget is set for this agent, an entry that would cross the monthly/daily cap is blocked, not just logged. Include tokens_in/tokens_out + model on every LLM call so token burn shows up in the /v1/tokens report.

AgentLedger — questions

Answers built from our own checks of this server.

What can AgentLedger do?

It exposes 7 tools, read directly from the server on our last check. Among them: ledger_alerts, ledger_api_docs, ledger_examples, ledger_list_agents, ledger_report, ledger_set_budget and 1 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is AgentLedger working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 93 of 93 checks got a reply (100.0%), average response time 360 ms. The bar chart above shows every period we have measured.

Is AgentLedger still maintained?

The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.

How do I connect AgentLedger?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does AgentLedger need an API key?

No. AgentLedger completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 7 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is AgentLedger?

It answers our handshake in 360 ms on average, which is faster than 46% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
