logs

logs is a command for Claude Code from Nodeflare-app/nodeflare-mcp. It costs 9 tokens per session (250 once invoked), scanned A, original, MIT.

A command for retrieving and summarizing blockchain event logs from a smart contract. Smart contracts are programs deployed on a blockchain, and event logs record actions they emit.

In plain words
What is it for?
Querying a contract by address, blockchain, and block range, counting events by signature, decoding supported common events, and highlighting notable transfers or active addresses.
Why use it?
It avoids manually filtering raw blockchain records and can group recognizable events such as token transfers or swaps.

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

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 10d 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.

What it actually says

Fetch and summarise event logs for a contract using the nodeflare MCP server.

  1. Parse $ARGUMENTS into: a contract address (required), an optional chain slug (default ethereum), and an optional block range (fromBlock/toBlock). If no range is given, first call get_block_number and query a recent window (e.g. the last few thousand blocks) so the range stays within limits.
  2. Call get_logs for that address and range.
  3. Summarise: how many events, grouped by the event signature (topic0). For recognisable signatures (ERC-20 Transfer/Approval, Uniswap Swap, etc.) decode and count them, and highlight notable entries (largest transfers, most active addresses).
  4. get_logs needs a keyed request — remind the user to set NODEFLARE_API_KEY (free tier: 2,000,000 CU/month at https://nodeflare.app) if the call reports the method is unavailable on the public tier.
Changes

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.
