3CX's read-only directory surface: resolving a caller by email or by exact extension, searching the PBX's own phonebooks, searching contacts synced from an integrated CRM, and listing PBX users/extensions.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 3CX Directory & Contacts ## Overview 3CX exposes read-only lookups across three sources: the PBX's own phonebooks (company and personal entries), the PBX's user/extension list, and — where the PBX has a CRM connector configured — contacts synced in from that CRM. All of it is read-only; nothing in this skill creates or edits a contact or extension. ## Anti-triggers - **The CRM record itself** — this skill only reads what 3CX has synced in or is querying live from a connected CRM. To create or edit the actual CRM contact, use `hubspot-contacts` or `salesbuildr-companies-contacts`. - **The client's documentation record** — extension lists and phone trees that belong in runbooks live in `hudu-companies`, not here. ## Capabilities Exact tool names are not published by 3CX — see the `api-patterns` skill for why, and call `tools/list` for the authoritative names on a connected PBX. The read-only capabilities this skill covers: - Find a contact by email - Find a contact by exact extension - Search CRM-integrated contacts - Search 3CX phonebooks - List PBX users/extensions ## Common Workflows ### Resolve a caller …

How to install
mdr add wyre-ai/msp-claude-plugins/3CX Directory & Contacts@sha256:4de11ae7248d5ffdThe line at the top of this page pins the label git:20260821.b0139ac, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
