Endpoint Security63
Transport & Reachability100
Schema Quality & AI Usability79
  • AI-judged instruction clarity (excellent).Pass
  • Context-footprint check failed: tool/resource definitions use about 638 tokens (~127/item across 5 items; 5 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management57
  • Stability check failed: schema churn in the 30 days we've observed: 1 tool removals, 2 breaking changes, 0 auth/transport breaks, 1 additions. See how to fix → Fail
Tool Coverage100
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 100% of tool parameters carry a description.Pass
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; "chat" implies "send" 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 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
  • Implements a current MCP spec version (2026-07-28).Pass
Install

How do I install the PERSONAIZER MCP server?

PERSONAIZER is a hosted endpoint at https://sessions.personaizer.com/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

MCP tools · 5 exposed · ~638 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
chat ~102

Send a message to a PersonAIzer persona and get its reply, including any knowledge-base cards it surfaces. Requires your account API key and the persona_id to speak as.

NameTypeReqDescription
messagestringyesThe message to send.
personaIdstringyesWhich persona to chat with (its Persona ID).
sessionIdstring|null–Continue an existing conversation by passing back the session_id from a previous chat call. Omit to start a new conversation.

No output schema declared.

No examples provided.

check_persona_status ~46

Poll the status of a persona build started by create_persona. Requires an account-level API key.

NameTypeReqDescription
jobIdstringyesThe job_id returned by create_persona.

No output schema declared.

No examples provided.

create_persona ~139

Start building a new PersonAIzer persona from a website URL — reads the site's brand facts, makes the brand, synthesizes the persona's identity and avatar, and (by default) crawls the site into the brand's knowledge; the persona and the crawl run in parallel. Asynchronous (~1 minute for the persona) — returns jobId, brandId and personaId; poll check_persona_status. Requires an account-level API key.

NameTypeReqDescription
harvestContentboolean–Whether to crawl the site into the brand's knowledge alongside the persona build (default true).
websiteUrlstringyesThe website URL to build the persona from.

No output schema declared.

No examples provided.

upload_knowledge_docs ~157

Upsert up to 100 PRODUCTS (including services and unpriced catalog entries) into a knowledge source. For plain text (FAQs, policies, guides, articles, notes) use upload_knowledge_text instead. Requires your account API key; the source must exist (POST /v1/knowledge/sources).

NameTypeReqDescription
itemsarrayyesThe products to upsert. Each needs title and categories (e.g. [["phones"]]); id, description, price, in_stock, attributes, variants, images and links are optional — see PersonAIzer's /v1/knowledge AP…
sourcestringyesThe knowledge source the products belong to — its name, e.g. my-shop.ge.

No output schema declared.

No examples provided.

upload_knowledge_text ~194

Add a piece of text — an FAQ, policy, guide, article or notes — to a knowledge source as a plain-text document. Uploading again with the same id replaces that document's text. For products (price, stock, attributes, variants) use upload_knowledge_docs. Requires your account API key and the source to write to; every persona speaking for that source's brand answers from it.

NameTypeReqDescription
contentstringyesThe full text of the document.
idstring|null–Optional stable identifier. Uploading again with the same id replaces that document's text; omit it to create a new document.
sourcestringyesThe knowledge source this belongs to — its name, e.g. my-shop.ge.
titlestringyesDocument title.
urlstring|null–Optional URL where this content lives — shown as the document's link when the persona cites it.

No output schema declared.

No examples provided.
