The B2B data MCP server for AI agents

Crustdata’s B2B data MCP server gives Claude, Cursor, and any MCP client live access to 1B+ people and 60M+ companies from 15+ sources. Company search, people search, enrichment, job signals, social posts, and web research run as tools your agent calls from a plain-English prompt.

What is a B2B data MCP server?

A B2B data MCP server is a Model Context Protocol endpoint that gives AI assistants like Claude direct access to company and people data as callable tools. Instead of exporting CSVs or wiring APIs, your agent searches, enriches, and monitors B2B data inside the conversation. Crustdata’s MCP server exposes 40 tools covering 1B+ people and 60M+ companies from 15+ sources.

Before MCP

Every query costs a context switch.

Teams bounce between tools, API docs, and data-team queues before

touching a single record.

Teams bounce between tools, API docs, and data-team queues before

touching a single record.

A subscription per workflow.

Prospecting tools, sourcing platforms, deal

screening software. Each paid separately, each

going stale on its own cadence.

Filters live in docs, not your head.

Every new list means re-reading the schema, guessing at field names, and testing until the query returns the right shape.

Custom queries wait in a queue.

Anything beyond a basic filter gets routed to the data team, added to a backlog, and returned after the window closes.

The shift

Queries move from filter UIs to conversation.

Add the MCP endpoint once. Every search, enrichment,

and monitoring step becomes a prompt anyone on the team

can write, with Claude picking the right tool and building

the query.

Every tool in the Crustdata MCP server

Seven tool groups cover company data, people data, jobs, social signals, web research, monitoring, and account utilities.

Company data

Identify, enrich, search, and run database searches across company records.

People data

Search, semantic search, enrich, contact enrich, and batch enrich people records.

Jobs

Run job search, live job search, and batch job search across companies and roles.

Social

Pull person posts, company posts, keyword posts, and Twitter posts into the agent workflow.

Web

Use web search and web fetch when an agent needs outside context alongside B2B data.

Watchers

Create, list, update, simulate, and review run history for monitoring workflows.

Utilities

Check credit costs, credit balance, and autocomplete filters before running larger prompts.

Use Cases

One MCP data provider, every workflow

Sales, recruiting, and investment teams run different queries. Claude handles
all of them through the same 40 tools.

What claude can do

Four capabilities, 40 tools, one conversation

Every surface of the Crustdata platform, exposed as an MCP tool Claude can reach for.

Build account and candidate lists from a prompt.

Describe the account profile or persona you need. Claude picks the right search tool, applies the filters, and returns a structured list you can refine in the same thread.

Pull social posts and web research in the same thread

Retrieve recent posts from target profiles, run a web search, or fetch a specific page without leaving the conversation.

Track hiring activity across target accounts

Ask Claude which companies are opening roles in sales, engineering, or leadership. Batch queries run across up to ten companies at once.

Create push-based alerts from a prompt

Tell Claude which job change, post, or role opening to watch. It configures the webhook and simulates the payload before going live.

Integration

Set up in five minutes, in any MCP client

Works natively with Claude.ai, Claude Code, Cursor, and any MCP-
compatible client.

STEP 01

Add the MCP endpoint

In Claude Settings, add a custom MCP server with the Crustdata URL. One field, one paste.

STEP 02

Authenticate once

Claude and Cursor sign you in with OAuth. No key to paste. File-based clients take your Crustdata API key in their config.

STEP 03

Query in plain English

Claude reads the prompt, picks the right tool, builds the query, and returns the structured response.

Claude (web and desktop)

Add the connector from Claude settings using the hosted endpoint, then approve with OAuth.

https://mcp.crustdata.com/mcp

Claude Code

Run the command once to add Crustdata as a hosted MCP server.

claude mcp add crustdata https://mcp.crustdata.com/mcp

Cursor

Add the hosted endpoint to mcp.json, then let Cursor open the OAuth approval flow.

mcp.json → https://mcp.crustdata.com/mcp

How it works

Connect the Crustdata MCP server to your MCP client.

Ask for the data you want in natural language.

The prompt resolves to a real API call against live data.

Structured results come back inside the conversation.

Under the hood

Every prompt resolves to a real API call.

Watch what Claude executes behind the natural-language surface.
