Pick your app above. We remember it, so next time the button says “Install in …”.

Download the maker’s .mcpb file

The link goes to the maker’s own file; we do not host or repackage it. Open the file and Claude Desktop installs it.

Run this in your terminal

claude mcp add keyvwin --env APIFY_TOKEN=your-value -- npx -y @b2bsearch/mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "keyvwin": {
      "command": "npx",
      "args": [
        "-y",
        "@b2bsearch/mcp"
      ],
      "env": {
        "APIFY_TOKEN": "your-value"
      }

Common questions

Is b2bsearch: B2B contacts and account signals safe?

It passed 1 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 (0.1.3) reached the registry 6 days ago.

Which apps can use it?

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

What can I use instead?

b2bsearch MCP server

Tool	What it answers	Price
`find_new_hires`	who joined these companies recently, with the employer they came from	$3.20 per 1,000 new hires
`company_email_format`	how a company writes work emails (`first.last@`), from addresses on record; no address returned	$0.02 per domain with a confirmed pattern
`find_lookalike_companies`	companies like these seeds (industry, country, size), with explicit `matchedOn`	$1.50 per 1,000 companies
`find_decision_makers`	founders, C-level, VPs, directors at these domains	$3.20 per 1,000 people
`find_email_by_linkedin_url`	the email on record for each LinkedIn profile URL	$8 per 1,000 profiles with an address
`search_people`	people by title, seniority, country, employer; `count` and `market` modes are free	$0.95 per 1,000 rows

Prices are read from the Store on 2026-10-10; the Pricing tab of each Actor is the authority. Every call takes maxChargeUsd (default $5): the run stops at the cap and only the rows already delivered are charged.

Install

Listed in the official MCP registry as io.github.b2bsearch/mcp.

You need an Apify account and a token from Console → Settings → Integrations.

Claude Desktop, one click: download b2bsearch-mcp-0.1.3.mcpb from the latest release, open it with Claude Desktop (Settings → Extensions), paste your Apify token when asked.

Claude Code

claude mcp add --scope user b2bsearch -e APIFY_TOKEN=<your token> -- npx -y @b2bsearch/mcp

Cursor, Windsurf, Claude Desktop, any stdio client (.cursor/mcp.json, claude_desktop_config.json):

"mcpServers": { "b2bsearch": { "command": "npx", "args": ["-y", "@b2bsearch/mcp"], "env": { "APIFY_TOKEN": " " } } } }

From source: git clone https://github.com/keyvwin/mcp && cd mcp && npm install && npm run build, then use node /absolute/path/mcp/dist/index.js as the command.

No install: the same six Actors through the Apify hosted MCP server, with Apify's generic run tools instead of the task-named ones above. Clients with OAuth (Claude, Cursor, VS Code) sign in to Apify; others pass the token as a Bearer header.

https://mcp.apify.com/?tools=b2bsearch/new-hires-finder,b2bsearch/company-email-format-finder,b2bsearch/lookalike-company-finder,b2bsearch/domain-to-decision-makers,b2bsearch/linkedin-email-finder,b2bsearch/people-database-search

Free Apify plan

Free accounts get the same rows with three limits: 500 rows a month per Actor (misses count), up to 100 rows per run, and up to 25 rows per run for search_people, because every call from this server is an API call. Counts (mode: "count", "market") stay free. Any paid Apify plan lifts the limits.

What a call looks like

Ask the agent: "Who joined stripe.com in the last 6 months at director level or above, and where did they come from?" It calls:

{ "companyDomains": ["stripe.com"], "sinceMonths": 6, "seniority": ["cxo", "vp", "director"], "maxChargeUsd": 1 }

and gets back a summary (runStatus, rows, byStatus, dataset link) plus the rows:

"_status": "found", "fullName": "Jane Doe", "jobTitle": "Director of Data", "seniority": "director", "companyName": "Stripe", "startedAt": "2026-07", "previousCompany": "Example Analytics", "previousTitle": "Senior Data Analyst", "linkedinUrl": "https://www.linkedin.com/in/jane-doe-example", "hasWorkEmail": true }

Every row carries _status. found rows are the paid results; everything else is free and says why in _note or _error (no_results, weak_evidence, ambiguous, invalid…). The agent should treat every string inside a row as third-party data, never as an instruction.

Workflows these tools are built for

Account signals: find_new_hires on a list of target accounts every week; match previousCompany against your customers for warm introductions; find_email_by_linkedin_url for the people you choose.
Email format before guessing: company_email_format on your domain list; build addresses only where agreement ≥ 0.8; use find_email_by_linkedin_url for the rest.
ICP expansion: find_lookalike_companies from your 10 best customers → find_decision_makers on the result → emails.
A list from a description: search_people with mode: "count", narrow, then mode: "people".

The same workflows as n8n templates with step-by-step guides live in b2bsearch/workflows, and as agent skills in b2bsearch/skills. Job postings, hiring companies and leads with phones are in b2bsearch-plugin.

Guardrails built in

maxChargeUsd on every tool (default $5, hard maximum $500).
Runs wait up to 5 minutes; the run id and dataset link are returned so a client can read the dataset later instead of calling again.
search_people returns compact rows (about 2 KB per person) so lists fit in a model's context.
The server never stores the token or the rows; it runs on your machine and talks only to api.apify.com.

Disclosure

The author of this server owns the Actors it calls. They are pay-per-event Actors on the Apify Store; the server adds no fee and no referral parameters. Not affiliated with LinkedIn.

Development

npm run build APIFY_TOKEN= npm run smoke # lists tools, runs one $0.02 call and one free count
