Common questions

Is MCP Contact Classifier safe?

It passed 0 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: APIFY_TOKEN

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.2.1) reached the registry 2 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

Contact Classifier MCP Server

MCP server for the Mamba Labs Contact Classifier actor on Apify.

Give it a job title and it returns the department and the seniority level. Give it a name and a company domain too, and it also checks whether that person is still listed on their employer's own website. The classification is a deterministic rule table, so it needs no API key and returns the same answer for the same title every time.

Install

npx -y @mambalabsdev/mcp-contact-classifier

Claude Desktop

"mcpServers": { "mamba-contact-classifier": { "command": "npx", "args": ["-y", "@mambalabsdev/mcp-contact-classifier"], "env": { "APIFY_TOKEN": "your-apify-token" } } } }

Get an Apify token at console.apify.com/account/integrations.

Tool

`classify_contact`

One contact in, one classified row out. Only the job title is required.

Input	Type	Required	Notes
`job_title`	string	yes	The contact's job title, exactly as you hold it. Classified by deterministic rules with no API key needed.
`full_name`	string	no	Only needed for position verification. Classification works without it. This name is never sent to any language model.
`company_domain`	string	no	Only needed for position verification. The company's website domain, with or without https.
`verify_position`	boolean	no	Check whether the person is still listed on their employer's own website. Adds roughly 3 seconds and 9 requests per contact, and needs both the name and the domain. Default `false`.
`use_llm_fallback`	boolean	no	Sends titles the rules cannot place to your own model, using the `LLM_API_KEY` secret environment variable on your own copy of the actor. Only the title is sent, never the person's name. Default `false`.
`llm_provider`	enum	no	`openai`, `anthropic` or `google`. Which provider your `LLM_API_KEY` belongs to. Only read when the LLM fallback is on. Default `openai`.
`llm_model`	string	no	Model id passed straight through to the provider. Only read when the LLM fallback is on. Default `gpt-4o-mini`.
`skipCache`	enum	no	Set to `true` to ignore cached results and classify from scratch. Default `false`.
`max_charge_usd`	number	no	Optional cost cap in USD for this run. The actor stops before an item that could take its charges past this amount. Omit to rely on the maximum cost per run set in Apify.

Reading the output

21 flat snake_case fields, one row per contact. department is one of 12, seniority one of 12, and seniority_rank is 1 to 12 so a decision maker filter is a comparison rather than a list of strings. classification_rule names the rule that fired, which is what makes the decision auditable.

With no LLM_API_KEY set, titles the rules cannot place come back null. The row is still returned.

Billing

You are charged per contact classified, plus a small actor start fee. The deterministic classification calls no model and no third party API.

Event	Price	Fires when
`apify-actor-start`	$0.00005	Once per run, on start, one event per GB of memory (minimum one). Apify's start event.
`contact-classified`	$0.003 (FREE tier), down to $0.00255 on GOLD and above	Once per contact, including a title the rules cannot place.

Full pricing is on the actor's Apify page. Running this server consumes Apify credits.

The tool starts the actor run and polls it to a finished status, so a run with verify_position on is not cut off at 300 seconds. A run that does not succeed comes back as an error with its run ID and status.

What this server does and does not do

It is a thin client for the Apify actor. It passes your input through and returns the actor's output unchanged. Every behavior described above lives in the actor, not here.

This actor does not discover people. The name and title come from you. It classifies a title and, optionally, checks a name against a page the employer published. To find people in the first place, use People Finder.

Errors are surfaced, never swallowed. An invalid input, an invalid token, an exhausted balance, a timeout, or a run that returns anything other than a dataset all come back as an explicit tool error rather than as an empty result.

The actor is on the Apify Store. This wrapper is MIT licensed.
