Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "secops-field-notes": {
      "command": "docker",
      "args": [
        "run",

        "--rm",
        "ghcr.io/labaccessnow/secops-field-notes-mcp:0.1.0"
      ]
    }
  }
}

Run this in your terminal

claude mcp add secops-field-notes -- docker run -i --rm ghcr.io/labaccessnow/secops-field-notes-mcp:0.1.0

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "secops-field-notes": {
      "command": "docker",
      "args": [
        "run",

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "secops-field-notes": {

    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Common questions

Is SecOps Field Notes safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.0) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Docker on your computer.

What can I use instead?

secops-field-notes-mcp

The things a security analyst does by hand a dozen times a shift, as tools your coding agent can call: score a CVE, pull the indicators out of a report and defang them for the ticket, read a phishing email's headers properly, work out what kind of hash that is, decode a JWT, turn a timestamp into something a human can read, peel a base64-of-hex payload, and check whether a CVE is on CISA's exploited-in-the-wild list.

Free, MIT, no account, no telemetry. Everything except the KEV lookup runs entirely on your machine.

Tools

Tool	What it answers	Network
`cvss_score`	CVSS 3.1 base score from a vector or the eight metrics, exactly as FIRST computes it	none
`extract_iocs`	Every IP, domain, URL, email, CVE id and hash in a blob of text — refanged on the way in, defanged on the way out	none
`defang_text`	hxxp[://], [.], [at] and back	none
`analyze_email_headers`	The Received chain in order with hop delays, the origin IP, SPF/DKIM/DMARC, and the mismatches phishing triage looks for	none
`identify_hash`	bcrypt, Argon2, yescrypt, Unix crypt, LM:NT, MD5/NTLM, SHA-1/224/256/384/512 — by shape, with what that implies	none
`decode_jwt`	Header, payload, times as dates; flags alg:none, expiry, tokens that never expire	none
`convert_timestamp`	Epoch s/ms/µs, Windows FILETIME, ISO 8601, RFC 2822 — into every form	none
`decode_layers`	Chain base64 / hex / URL / HTML-entity / ROT13 decoding and see each layer	none
`lookup_kev`	Is this CVE exploited in the wild — CISA KEV date added, due date, ransomware use, required action	CISA feed, cached 1h
`latest_field_note`	What got exploited this week	RSS

analyze_email_headers

Paste the raw source. It unfolds the headers, reads the Received lines in chronological order (they are stored newest-first), computes the delay at each hop, finds the first public IP in the chain, reads the authentication verdicts, and then says what a triage analyst would say:

From        "IT Helpdesk" <helpdesk@corp.example>

Reply-To helpdesk-reset@evil-mail.example Auth SPF pass · DKIM pass · DMARC fail Origin IP 192.0.2.44

Received chain (origin first, 3 hops):

[10.0.0.5] [192.0.2.44] → relay.example-news.com 2026-09-05 13:59:50Z
relay.example-news.com [198.51.100.9] → mx3.corp.example 2026-09-05 14:00:15Z +25s
mx3.corp.example [203.0.113.30] → inbox.corp.example 2026-09-05 14:00:20Z +5s

Warnings: ! From domain (corp.example) ≠ Return-Path domain (mailer.example-news.com) … ! Reply-To goes to a different domain (evil-mail.example) than From (corp.example) — classic BEC pattern. ! DMARC verdict: fail.

cvss_score

The arithmetic is the FIRST specification's, including the Roundup function done in integer arithmetic so floating-point noise never pushes a 4.0 to a 4.1. Log4Shell's vector scores 10.0; AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H scores 9.8. Both are in the test suite.

What it does not do

No account, no signup, no key. No telemetry.
Nothing is read from your disk; every input is text you pass in.
No verification of JWT signatures — it decodes, and says so on every result.
One network call in the package: lookup_kev fetches CISA's public catalog (about 1.7 MB) and keeps it for an hour. Everything else never opens a socket.
It does not query VirusTotal, AbuseIPDB or any enrichment service. Those need keys and accounts; this server is for the work you do before and after them.
