logs

logs is a command for coding agents from gprot42/grok-mcp-cloudrun. It costs 18 tokens per session (437 once invoked), scanned A, original, Apache-2.0.

A command that retrieves recent logs and errors for a Google Cloud Run service. Cloud Run is Google's service for running applications and jobs in the cloud.

In plain words
What is it for?
Use it with a service name to fetch and clearly present its recent logs, highlighting errors and warnings. It requires a configured Google Cloud project and authentication.
Why use it?
It gathers service output in one place so you can investigate failures, warnings, and recent behavior without manually locating the logs.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 4d 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

Cloud Run Logs

Fetch recent logs and error messages for a Cloud Run service.

Usage

/logs [service-name]

If no service name is given, use DEFAULT_SERVICE_NAME from the environment, or the basename of the current working directory.

Instructions

You are a Cloud Run logs assistant. Fetch logs for the requested service using the Cloud Run MCP server.

Step 1: Prerequisites

Before fetching logs, verify:

  1. GOOGLE_CLOUD_PROJECT is set (or gcloud config get-value project returns a project)
  2. Application Default Credentials exist (gcloud auth application-default login if missing)

Step 2: Resolve service name

Service name priority:

  1. Argument from /logs <name> if provided
  2. DEFAULT_SERVICE_NAME environment variable
  3. Basename of the current working directory

Step 3: Fetch logs via MCP

Call cloud-run__get-service-log with:

  • Service name (resolved above)
  • Project: GOOGLE_CLOUD_PROJECT
  • Region: GOOGLE_CLOUD_REGION or us-central1

Use search_tool to find the tool if needed, then use_tool with the fully-qualified name.

Step 4: Present results

Format log output clearly:

  • Highlight errors and warnings
  • Show timestamps when available
  • If the service does not exist, suggest cloud-run__list-services to find available services

Examples

/logs
/logs hello-test
/logs my-api

Error handling

Error Fix
Service not found Run cloud-run__list-services to list services in the project/region
ADC not configured gcloud auth application-default login
Permission denied Ensure roles/logging.viewer and Cloud Run read access

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.
