elasticsearch-logs

elasticsearch-logs is a skill for Claude Code, Codex from automateyournetwork/netclaw. It costs 101 tokens per session (1,487 once invoked), scanned A, original, Apache-2.0.

A read-only tool for searching and analysing data already stored in Elasticsearch, a system that indexes logs and other events for fast queries. It can work with system, application, network-security, and other indexed logs.

In plain words
What is it for?
Use it to search logs, count events accurately, compare hosts or devices, and identify recurring errors or activity in an existing Elasticsearch cluster.
Why use it?
It helps answer questions about errors, event frequency, affected hosts, and other patterns without manually reading log files. It also avoids misleading counts when a search result exceeds Elasticsearch's default counting limit.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

elasticsearch-logs scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Elasticsearch Logs

Read-only log search over an Elasticsearch cluster you already run. NetClaw installs no cluster and indexes nothing — this queries what is already there.

Server: elasticsearch-mcp (adopted, docker.elastic.co/mcp/elasticsearch, Apache-2.0, digest-pinned) · 5 tools · 1,094 tokens

The rule that matters most

A bare search total is capped at 10,000 and reads as if it were exact.

Elasticsearch stops counting at 10,000 and marks the total relation: "gte" — meaning at least. This server discards that qualifier and prints Total results: 10000. There is nothing in the response to tell you the number is a floor.

Measured against 10,075 real documents:

How you ask What you get
search with no guard Total results: 10000wrong
search with "track_total_hits": true Total results: 10075 — correct
esql STATS COUNT(*) 10075 — correct

On a million-document index a bare search still says 10,000. The error is unbounded and invisible.

Therefore, for any question of the form "how many", "how often", "which is most", or any number a human will act on:

  1. Use esql with STATS COUNT(*), or
  2. Use search with "track_total_hits": true in the query_body.

search without that guard is for retrieving example documents only — never for counting. If you report a total that came from an unguarded search, you are reporting a number that may be arbitrarily wrong.

Tools

Tool Use it for Required arguments
list_indices what indices exist, and their document counts index_pattern (use *)
get_mappings field names and types before writing a query index
search retrieving matching documents (Query DSL) index, query_body
esql counting, aggregating, grouping, ranking query
get_shards shard health when results look incomplete

Note the argument names are snake_case (query_body, index_pattern). Wrong names fail loudly with a deserialization error — they are not silently ignored.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
