AIOps Field Notes

io.github.getlarkwrightPublished by GitHub account getlarkwrightv0.1.2Updated Nov 7, 2026

Audit an MCP config, price a model, size a GPU, explain network config drift. Key-free.

Overview

AI-generated overview

Key-free local MCP server with AI-ops calculators: LLM cost estimates, GPU VRAM sizing, MCP config audits, and network config diff and compliance checks.

What you can do
  • Estimate monthly LLM workload cost across models, cheapest first, and check whether a model fits in GPU VRAM at a given quantization and context
  • Audit a pasted MCP client config for unpinned versions, plaintext secrets, wide filesystem roots, privileged containers, shell entrypoints and plain HTTP
  • Look up an MCP server's publisher and whether it is reference, vendor or community
  • Diff two network device config snapshots and check a config against CIS/PCI basics
  • Fetch the latest AI-ops field note from a public RSS feed
When to use it
Useful when planning AI budgets or GPU purchases, when reviewing an MCP client config before trusting it with production access, or when explaining what changed on a network device between two snapshots.
Requirements
Runs locally over stdio. Node 18 or newer for the npx route, or Docker for the container image. No account, API key or environment variables; the README recommends pinning the version.
Before you install
The audit tool takes config text as input, so pasted configs may contain plaintext secrets such as API keys; the server reports them but does not read your disk. Only latest_field_note makes a network call, fetching a public RSS feed. Cost and GPU figures are reference data and pricing changes, so verify against the vendor before committing a budget.

Installation

In SourceWeft

  1. Open AIOps Field Notes in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

README

AIOps Field Notes MCP server

Four things I kept doing by hand while running AI in production, turned into tools an agent can call: price a model before committing a budget, size a GPU before ordering one, review an MCP config before trusting it, and explain what changed in a network device config.

Free, MIT, no account, no telemetry.

Install

Pin the version — see audit_mcp_config for why.

Claude Code

claude mcp add aiops-field-notes -- npx -y github:getlarkwright/aiops-field-notes-mcp#v0.1.2

Claude Desktop, Cursor, or any client with a JSON config

json
{  "mcpServers": {    "aiops-field-notes": {      "command": "npx",      "args": ["-y", "github:getlarkwright/aiops-field-notes-mcp#v0.1.2"]    }  }}

Docker

json
{  "mcpServers": {    "aiops-field-notes": {      "command": "docker",      "args": ["run", "-i", "--rm", "ghcr.io/getlarkwright/aiops-field-notes-mcp:0.1.2"]    }  }}

Node 18 or newer for the npx route; nothing else to configure either way. The server is also in the official MCP registry as io.github.getlarkwright/aiops-field-notes-mcp.

Tools

ToolWhat it answers
estimate_llm_costWhat does this workload cost per month on each model, cheapest first?
check_vram_fitDoes a 70B model at Q4 fit on my 4090 with a 32K context?
audit_mcp_configIs this MCP config safe to trust — what can each server actually reach?
lookup_mcp_serverWhat is this server, who maintains it, and is it reference, vendor or community?
explain_config_diffWhat changed on this router between two snapshots, and how bad is it?
check_config_complianceDoes this device config pass the CIS/PCI basics?
latest_field_noteWhat happened in AI ops this week?

audit_mcp_config

The one I use most. Paste a client config and it reads it the way a reviewer would — every server entry is an access grant, so the questions are what it can reach, who publishes it, and what happens the next time it auto-updates:

6 servers reviewed — 7 high, 6 medium, 0 low.
files  [high] Package version is not pinned    files runs "@modelcontextprotocol/server-filesystem" at whatever version is published when it launches.    fix: Pin it — "@modelcontextprotocol/server-filesystem@<version>" for npm, "@modelcontextprotocol/server-filesystem==<version>" for uvx — and bump deliberately.  [high] Filesystem root is wide open    files is granted "/" — that is the whole home directory or the whole disk, including keys and browser profiles.    fix: Scope the server to the project directories the agent actually works in.  [medium] Installs without prompting    files passes -y, so a new release installs and runs with no confirmation.    fix: Keep the flag only alongside a pinned version, so what installs is what you reviewed.
notes  [high] Package version is not pinned    notes runs "some-random-notes-mcp" at whatever version is published when it launches.    fix: Pin it — "some-random-notes-mcp@<version>" for npm, "some-random-notes-mcp==<version>" for uvx — and bump deliberately.  [high] Secret is stored in the config file    notes has NOTES_API_KEY written out in plaintext; config files get committed, synced and screenshared.    fix: Reference the environment instead — "NOTES_API_KEY": "${NOTES_API_KEY}" — and keep the value in your secret store.  [medium] Installs without prompting    notes passes -y, so a new release installs and runs with no confirmation.    fix: Keep the flag only alongside a pinned version, so what installs is what you reviewed.  [medium] Publisher not in the tracked set    "some-random-notes-mcp" is not one of the reference or vendor servers this directory tracks.    fix: Read the source and check the publisher before wiring it into an agent that touches production.

It also flags shell entrypoints, privileged containers, host-root mounts, credentials on the command line, database access that is not read-only, unauthenticated remote servers, and anything reached over plain HTTP.

What it does not do

  • No account, no signup, no key.
  • No telemetry. Nothing about your usage leaves your machine.
  • No filesystem access. audit_mcp_config takes the config as text, so the server never reads your disk.
  • One network call in the whole package: latest_field_note fetches a public RSS feed. Skip that tool and this server never opens a socket.

The cost table, GPU list and server directory match the calculators at aiopsfieldnotes.com/tools and get re-verified with each weekly episode. Pricing moves — check the vendor's page before you commit a budget to it.

Where the network tools come from

explain_config_diff and check_config_compliance are the read-only core of DriftWatch, which runs the same rules nightly across a fleet and keeps the history. Here you get the single-shot version, on two snapshots you paste, with no storage and no scheduler. That is deliberate: the rules are the useful part, and they work fine on their own.

Score

50% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
