marzban-mcp

Update user

marzban_users_update

Partially updates a Marzban user by changing only supplied fields while leaving all other settings unchanged; use it for targeted profile edits, not status changes or renewals.

Instructions

Partially updates a user — only fields you provide are changed, everything else is left as-is. For status changes prefer marzban_users_activate/deactivate/hold (clearer intent, no need to know the raw status enum). For renewing an expiring/expired user prefer marzban_users_extend.

Input Schema

Name	Required	Description
`note`	No
`expire`	No	e.g. "30d" or an absolute date. 0 means unlimited.
`proxies`	No	Protocol name -> settings, e.g. {"vless": {"id": "<uuid>"}} or {"shadowsocks": {}} to auto-generate credentials. Omit to leave unchanged on update. On create there is no server default — omitting this (without templateId) errors; provide at least one protocol with a matching inbound configured on the panel.
`inbounds`	No	Protocol name -> inbound tags to restrict this user to. Omit for all inbounds.
`username`	Yes
`dataLimit`	No	e.g. "10GB". 0 means unlimited.
`dataLimitResetStrategy`	No

First observedv0.2.2Sep 2, 2026

TDQS

A4.3/5.0

Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare non-read-only, non-destructive, so the safety bar is lower. The description adds the key behavioral detail beyond them: omitted fields are left as-is, which tells the agent this is a merge-patch rather than a replace. It stops short of stating permission requirements or whether inbounds/proxies changes disrupt active connections.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences, front-loaded with the core merge semantics, followed by the routing rules. Every clause carries actionable information; nothing is filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With annotations and an output schema present, the description covers the one thing an agent must know to avoid data loss (merge vs replace) and the sibling routing. Remaining gaps are the undocumented enum and nested-object parameters rather than missing conceptual framing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is only 57% and the description adds no meaning for any of the 7 parameters — no guidance on dataLimitResetStrategy (the undocumented enum), note, or the nested proxies/inbounds interplay. The partial-update framing implies 'omit to keep' but never says it per-parameter, so agents still depend on the uneven schema text.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

"Partially updates a user — only fields you provide are changed" names a specific verb (partial update), resource (user), and semantics (merge not replace). It is immediately distinguishable from marzban_users_create and the status-toggle siblings.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly routes two common intents away from this tool: status changes go to activate/deactivate/hold, renewals go to extend, with a stated reason (clearer intent, no raw status enum). A rare case of naming alternatives and the condition that selects them.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
