3CX PBX Admin & Diagnostics

3CX PBX Admin & Diagnostics is a skill for Claude Code from WYRE-AI/msp-claude-plugins. It costs 78 tokens per session (1,262 once invoked), scanned A, original, Apache-2.0.

A toolkit for inspecting and managing a 3CX phone system, also called a PBX, which routes calls for an organization. It covers diagnostics, logs, services, databases, phone numbers, blocklists, SIP trunks, and call-flow applications.

In plain words
What is it for?
Use it to check server time and logs, inspect services and database tables, list phone numbers and blocklists, review SIP trunks and call-flow apps, run SELECT queries, and manage supported call-routing settings.
Why use it?
It brings system status and configuration checks into one interface and includes a read-only SQL query tool. Some listed actions can change which calls the PBX accepts or how it routes them.

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

3CX PBX Admin & Diagnostics 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 8d 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.

3CX PBX Admin & Diagnostics

Overview

This is the plugin's system-level surface: diagnostics, the PBX's own configuration inventory, a restricted database query tool, call flow app details, and the smaller set of write/delete actions that change what calls the PBX will accept or how they route.

Read-Only Capabilities

Exact tool names are not published by 3CX — see the api-patterns skill and call tools/list for the authoritative names on a connected PBX.

System and diagnostics

  • Get current PBX server time
  • Search/list structured PBX event log
  • List PBX services and their state
  • Search application logs

PBX inventory and database

  • Describe a database table's schema
  • List DIDs
  • List IP blocklist entries
  • List configured PBX peers
  • List phone blacklist entries
  • List accessible database tables
  • List configured SIP trunks
  • Run a read-only SQL SELECT query (the Query tool)

Call flow tools

  • Get a call flow app's details
  • Get a call flow app's files
  • Get an edit URL for a supported PBX object
  • List call flow apps

The Query tool

The Query tool is hard-restricted server-side to read-only SQL SELECT statements, regardless of the connecting account's 3CX role — this holds even for an account that could otherwise change configuration. That restriction is enforced inside the PBX itself.

It is not automatically safe from a Conduit-permission standpoint, though, if this PBX is reached through Conduit's BYO connector rather than a direct connection: Conduit's tiering heuristic reads the tool's name, not the PBX's server-side enforcement. See the api-patterns skill's section on BYO tool tiering — if the tool's real name doesn't start with a recognized read verb, Conduit will still gate it as write. Check the tool's actual granted tier rather than assuming SELECT-only implies read.

Write/Delete Capabilities — Read This Before Calling Any of Them

  • Add an IP address to the IP blocklist
  • Add a number to the phone blacklist
  • Assign a DID
  • Remove an IP blocklist entry
  • Remove a phone blacklist entry

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.
