How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →

Supply Chain Security100
  • No malware found by supply-chain analysis.Pass
  • No known CVEs affecting this package version or its production dependencies.Pass
  • No install/post-install scripts declared.Pass
  • No production dependencies, so there is no dependency health to assess. View diagnostics → Pass
Provenance & Transparency97
  • Source repository is publicly reachable at the declared URL. View diagnostics → Pass
  • Cryptographically verified build provenance (signed, bound to leek-emperor/Personae). View diagnostics → Pass
  • Clear OSI-approved license (MIT).Pass
  • Actively maintained (last published 11 days ago).Pass
  • Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability80
  • AI-judged instruction clarity (excellent).Pass
  • Tool/resource definitions use about 1266 tokens (~97/item across 13 items; 13 tools + 0 resources), lean.Pass
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management40
  • Stability observed for 12 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage88
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 65% of tool parameters carry a description.Partial
Tool Safety75
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "eval_js" implies "eval" and declares no destructiveHint at all, which the MCP spec reads as destructive by default. See how to fix → Fail
  • An AI judge read all 13 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities60
  • Spec-recency check failed: implements MCP spec 2025-06-18; the latest is 2026-07-28. See how to fix → Fail

MCP tools · 13 exposed · ~1,266 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
act ~143

在一次调用内对同一身份连续执行多个 agent_browser 命令，ref 在这些命令之间有效。适合「snapshot → 点这个 → 填那个 → 回车」这种多步流程。命令用 agent_browser 语法，如 ["snapshot -i", "fill @e35 关键词", "press Enter"]。会自动前置 tab 切换。

NameTypeReqDescription
commandsarrayyesagent_browser 命令字符串数组，按顺序在同一进程内执行
identitystringyes–
targetstring–可选：子窗口 targetId 或序号，不传则操作主窗口

No output schema declared.

No examples provided.

click ~120

点击指定身份窗口中的元素。按元素可读名称定位（推荐），或直接给 @eN ref —— 本工具内部会先重新 snapshot 再点击，所以 ref 用的是最新一次快照的编号。

NameTypeReqDescription
identitystringyes–
refstring–@eN 形式的元素 ref
targetstring–可选：子窗口 targetId 或序号，不传则操作主窗口
textstring–元素可读文本，如「百度一下」；与 ref 二选一

No output schema declared.

No examples provided.

eval_js ~68

在指定身份窗口内执行 JavaScript 并返回结果。用于读取页面状态、验证隔离等。

NameTypeReqDescription
expressionstringyes–
identitystringyes–
targetstring–可选：子窗口 targetId 或序号，不传则操作主窗口

No output schema declared.

fill ~117

清空并填入文本。按元素可读名称/label 定位（推荐），或给 @eN ref（内部会先重新 snapshot）。

NameTypeReqDescription
identitystringyes–
labelstring–输入框的 label 或占位文本；与 ref 二选一
refstring–@eN 形式的元素 ref
targetstring–可选：子窗口 targetId 或序号，不传则操作主窗口
textstringyes要填入的内容

No output schema declared.

No examples provided.

get_text ~78

读取元素文本。可传 @eN ref（内部会先重新 snapshot）或 CSS 选择器。

NameTypeReqDescription
identitystringyes–
refstringyes@eN ref 或 CSS 选择器
targetstring–可选：子窗口 targetId 或序号，不传则操作主窗口

No output schema declared.

No examples provided.

get_url ~47

读取该身份窗口当前的 URL。

NameTypeReqDescription
identitystringyes–
targetstring–可选：子窗口 targetId 或序号，不传则操作主窗口

No output schema declared.

No examples provided.

list_identities ~59

列出所有浏览器身份（partition）及其 CDP targetId、是否已打开、当前页面。任何操作前先调用此工具确认身份状态 —— 这是把 partition 对应到 CDP target 的唯一途径。

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

load_skill ~188

Load agent-browser 官方命令语法说明，内容随本机捆绑的二进制版本，保证 flag 真实存在。**在用 act 工具手写 agent-browser 命令前必须先调用本工具** —— 它的语法在版本间会变（本机版本就没有网上文档里的 `tab --url` 和 `--pin-tab`），凭记忆猜必然失败。注意：本 app 的多身份窗口应优先用 snapshot/click/fill/navigate 等专用工具操作，它们已处理好「身份→窗口」定位；只有需要专用工具没覆盖的能力时才手写命令。

NameTypeReqDescription
sectionstring–可选：只关心某方面时填关键词过滤，如 snapshot / click / tab / eval / screenshot / batch。留空返回全部语法。

No output schema declared.

No examples provided.

navigate ~74

在指定身份的窗口内导航到 URL。跳转被限制在该窗口内，不会新开窗口或外跳系统浏览器。

NameTypeReqDescription
identitystringyes–
targetstring–可选：子窗口 targetId 或序号，不传则操作主窗口
urlstringyes–

No output schema declared.

No examples provided.

open_identity ~50

打开（或聚焦）指定身份的浏览器窗口。窗口打开后才会生成 targetId，agent 才能操作它。

NameTypeReqDescription
identitystringyes身份 id 或名称

No output schema declared.

No examples provided.

press ~65

发送按键，如 Enter、Tab、Control+a。作用于该身份窗口当前焦点。

NameTypeReqDescription
identitystringyes–
keystringyes–
targetstring–可选：子窗口 targetId 或序号，不传则操作主窗口

No output schema declared.

No examples provided.

screenshot ~68

截图指定身份的窗口，保存到给定绝对路径。

NameTypeReqDescription
identitystringyes–
pathstringyes输出文件绝对路径，.png
targetstring–可选：子窗口 targetId 或序号，不传则操作主窗口

No output schema declared.

No examples provided.

snapshot ~189

读取指定身份窗口的可交互元素快照（accessibility tree + @eN refs）。会自动定位到该身份的窗口，不会读到别的身份。注意：ref 只在单次调用内有效，click/fill 等工具会各自重新 snapshot，因此你只需把「元素的可读名称」记住，让后续工具自己按名称定位；若要按 ref 操作，请用 act 工具在一次调用内完成。若要读该身份下弹出的子窗口（OAuth/分享等），传 target=子窗口的 targetId（见 list_identities）。

NameTypeReqDescription
compactboolean–精简输出，默认 true
identitystringyes身份 id 或名称
targetstring–可选：该身份下子窗口的 targetId 或序号，不传则操作主窗口

No output schema declared.

No examples provided.

Common questions

What is the Personae MCP server?

Personae is an MCP server listed in the public MCP registry as io.github.leek-emperor/personae. Control specific, already-open account-isolated Personae browser identities with MCP. This page covers its npm package (@leek-emperor/personae-mcp).

Is the Personae MCP server safe to use?

Personae scores 83 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 20 September 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

What tools does the Personae MCP server expose?

Personae exposes 13 tools: load_skill, list_identities, open_identity, snapshot, navigate, and 8 more. Their descriptions and schemas cost roughly 1,266 tokens of context every time the server is loaded.

Is the Personae MCP server still maintained?

Personae is still listed as active in the MCP registry. We last reached this channel on 20 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

What licence is the Personae MCP server under?

Personae declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
