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.

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 | $0.00093 | $0.02139 |
| Opus 5 | $0.00046 | $0.01069 |
| Sonnet 5 | $0.00019 | $0.00428 |
| Haiku 4.5 | $0.00009 | $0.00214 |
Grade A, and why
3CX API Patterns 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.
How it starts
The opening of the file, as written. The whole thing — 190 lines — stays where its author put it; the contents beside it link to each section on GitHub.
3CX API Patterns
Overview
3CX added a native MCP server built directly into the PBX, introduced in 3CX V20 Update 10 (announced July 30, 2026 as an Alpha release — 3CX's own release notes describe Update 10 Alpha as "intended for testing and evaluation only"). Treat everything in this plugin as based on that Alpha: exact tool names, the permissions reference, and behavior may all shift before 3CX ships Update 10 GA.
This is a different project from the older third-party SSIG-IT/3cx-mcp-server on GitHub, a community-built MCP server that talks to 3CX's REST API rather than shipping inside the PBX. Do not mix the two up, and do not carry claims from the community project into this one — in particular, its "Enterprise/Enterprise Plus license required" claim is specific to that project and is not confirmed for 3CX's native MCP server.
Anti-triggers
- The community 3cx-mcp-server project — different codebase, different tool surface, different auth model (its own API-key setup rather than per-PBX OAuth). Nothing in this plugin describes it, and nothing about it should be assumed here.
- A customer's "the phones are down" ticket — that's ticket handling in
the PSA, not a 3CX MCP call. Use
halopsa-tickets,connectwise-psa-tickets, orautotask-ticketsto work the ticket itself; come back to this plugin once you need the PBX-side facts. - WYRE's Conduit vendor catalog — 3CX has no catalog entry there and, structurally, cannot: Conduit's catalog vendors share one fixed endpoint per vendor, and every 3CX PBX is its own origin with its own authorization server. See Connection & Authentication below for the two ways this plugin actually reaches a PBX.
Connection & Authentication
Every PBX is its own endpoint
Unlike a hosted SaaS MCP server, there is no single 3CX MCP URL. Each PBX exposes its own endpoint at its own FQDN, following the pattern:
https://yourpbx.3cx.eu/mcp
(or whatever FQDN that customer's PBX actually uses). Transport is Streamable HTTP. A skill, command, or agent in this plugin that needs to call a tool always does so against whichever PBX endpoint the current session is already connected to — nothing here can assume a fixed URL across customers.
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.

3CX API Patterns is a skill published in the GitHub repository WYRE-AI/msp-claude-plugins (44 stars, last pushed yesterday), licensed Apache-2.0. It adds 93 tokens to every session and 2,139 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

watch
File sentinel that monitors the working directory for changes and marker comments, then auto-triggers appropriate skills. Poll-based via git diff against the last scan commit. Writes intake items for batch processing and routes marker actions through /do. Use for automatic reactions to file changes; do NOT use for…
live-preview
Mid-build visual verification loop. Takes screenshots of components during construction, not just after. Catches visual regressions and invisible features before they compound. Requires Playwright or similar screenshot tool.

audit-project
Run an iterative multi-agent code audit until critical and high findings are resolved. Use when the user says "audit my code", "find all the bugs", "deep code audit", "iterative review", or "review until clean".
programming-swift
Provides the complete content of 'The Swift Programming Language (6.4 beta)' book by Apple. Use this skill when you need to verify Swift syntax, look up language features, understand concurrency, resolve compiler errors, or consult the formal language reference.
axiom-mode
Use when the user requests axiom, axiom-mode, axiom-compact, formal-logic, or compact form. Switches responses to compact formal-logic English with predicate claims and ASCII keywords, then restores the register after clarity exceptions. Not for changing code or remote state.
