What is mcplogview CLAUDE.md?

Repository instructions for mcplogview, a tool for viewing logs, including build commands, configuration, MCP communication, and SSH log sources. SSH is a protocol for securely connecting to another computer.

Building and testing mcplogview, configuring log sources, viewing logs over SSH, and creating or verifying its portable Node.js binary.

They document setup details and warn that ordinary output on stdout can break MCP clients; diagnostic messages must use stderr or logging.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00440	$0.00440
Opus 5.5	$0.00176	$0.00176
Sonnet 5.5	$0.00088	$0.00088
Haiku 4.5	$0.00044	$0.00044

Security

Grade A, and why

mcplogview CLAUDE.md 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 2mo 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

CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

@AGENT.md

Commands

npm run build   # TypeScript compile → dist/
npm run dev     # Run directly with tsx (no build step needed)
npm test        # vitest run (unit + integration)

Portable build (Node.js SEA):

npm run portable:build    # produces dist/portable/
npm run portable:verify   # smoke-test the binary
npm run portable:checksums

Critical: stdio transport

In stdio mode, only valid MCP JSON-RPC may go to stdout. All debug output, warnings, and errors must go to stderr or logging.path. Writing anything else to stdout breaks MCP clients silently.

Config

LOG_SOURCES_CONFIG env var sets the config file path (default: config/log-sources.json)
config/log-sources.json is gitignored — copy from config/log-sources.example.json
If the config file is missing, the server auto-creates a minimal debug config with self-log enabled

SSH sources

SSH tailing spawns ssh as a subprocess with BatchMode=yes (non-interactive). No SSH library is used. identityFile is passed via -i.

Skill files

Optional per-source skills live in config/log-skills/<sourceId>.md (frontmatter + markdown body). The mcplogview-self skill is built-in and not file-loaded.

MCP tools

Tool	Purpose
`list_logs`	Lists configured sources with labels and hints
`get_log_skill`	Returns structured + markdown skill for a source
`read_log_chunk`	Returns lines + next cursor (cursor-based paging)
`follow_log`	Short-polls for new lines until timeout

Recommended agent flow: list_logs → get_log_skill → read_log_chunk / follow_log.

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.
