Mcp MCP Server

b2bsearch MCP server

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": "<your 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.

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.
