Verified contact data for your AI agent

The MoltSets MCP server gives Claude, ChatGPT, Cursor and any other MCP client live access to verified business emails, carrier-verified mobiles, people and company search and the full identity graph — in a single tool call. No code, no CSVs: ask in plain English and your agent does the lookups.

what it is

An MCP server built for AI agents

The Model Context Protocol is an open standard that lets an AI assistant connect directly to external tools and data, instead of relying on what it remembers from training.

Connect MoltSets and your agent reads the real tool list, parameters and response shapes — so it enriches, searches and resolves identities correctly on the first try, without leaving the conversation.

how you use it

No UI. Just data, wherever you need it.

MoltSets is data only. You don't log in to a dashboard. You pull verified records into the tools and workflows you already use.

Used MoltSets integration, loaded tools

I enriched all 240 signups from webinar-signups.csv with MoltSets. 221 now have a validated work email and 164 have a carrier-verified mobile number. 19 contacts have changed jobs since they registered, so I updated their company and title.

About the data:

  • Work emails only. Twelve signups registered with Gmail or Outlook; I replaced those with their current business address where MoltSets had one.
  • 19 job changers are flagged in a new column, with their previous company kept for reference.
  • Mobiles cost one phone token each, so you were only charged for the 164 numbers found.

Want me to export this as a CSV, or push the 19 job changers to your CRM as new leads?

use cases

What people ask their agent to do

01 / Enrich a LinkedIn list

Paste a batch of profile URLs and get back a table of business emails, each with its A–F risk score.

02 / Find decision-makers

Name your target accounts and the titles you sell to. The agent searches, then enriches the people it finds.

03 / Build lead lists from scratch

Describe your ICP — title, seniority, industry, headcount, location — and let the agent assemble the list.

04 / De-anonymise site visitors

Hand over an IP address and get the company behind it, then go looking for the right contact there.

05 / Build ad audiences

Turn LinkedIn profiles or business emails into SHA256 hashed emails for Meta, Google or LinkedIn custom audiences.

06 / Run a waterfall in Claude Code

Have Claude Code chain lookups — business email, then best email, then the full profile — without writing glue code.

Connected in about two minutes.

  1. 01 /

    Create a connector

    Sign up free, then open Connectors in the MoltSets app to get a Client ID and Client Secret.

  2. 02 /

    Add the server URL

    Point your client at https://mcp.moltsets.com/mcp. In Claude.ai and ChatGPT that is a custom connector; in Claude Code it is one terminal command.

    Approve and ask

    Approve access on the MoltSets consent screen. The tools appear to your agent automatically — just ask for what you need.

Talk to it like a colleague

Once the connector is live, there is nothing to learn. Try one of these, or browse the GTM skills library for ready-made workflows.

  • “Enrich this LinkedIn profile and give me their business email and phone number: linkedin.com/in/example”
  • “I have an IP address from a site visitor — 192.0.2.1 — can you tell me who this is?”
  • “Here are 10 LinkedIn URLs. Enrich each one for business email and return the results as a table.”
  • “Find VPs of Sales at US software companies with 50–200 employees, and get their verified emails.”

built for agents

Why agents run better on MoltSets

01 / Flat-rate pricing

Unlimited plans mean an agent that loops doesn’t run up a bill. No cost caps or call-counting logic to write.

02 / Misses cost nothing

A lookup that finds nothing returns status: "not_found" and is never charged, so the agent can try the next tool freely.

03 / Free dry runs

Count a search before pulling it, and check balance and usage, without spending a token.

04 / One response shape

Every tool returns the same envelope. An agent that has read one result can read them all.

Questions & answers about the MoltSets MCP

Connecting AI agents to MoltSets. More in the MCP troubleshooting guide.

It is a remote Model Context Protocol server at https://mcp.moltsets.com/mcp. Connect it to an AI assistant and the assistant can call every MoltSets tool — people and company search, email and mobile enrichment, reverse lookups, IP-to-company and ad-audience hashes — directly from the conversation, using the real tool schemas rather than guessing at them.

Claude.ai, Claude Desktop, Claude Code, ChatGPT, Cursor, Windsurf and Grok all have step-by-step guides. Any other client that supports remote HTTP MCP servers with OAuth will work too.

No. Add the connector, approve it, and talk to your agent in plain English. If you want MoltSets inside your own software or a workflow tool, use the REST API instead — it calls the same tools.

Over OAuth. You create a Client ID and Client Secret under Connectors in the MoltSets app, add them to your client, and approve access in the browser. On Team and Enterprise Claude accounts each seat authorises itself, so there are no API keys to hand around.

No — they lead to the same product, data and limits. The MCP is for using MoltSets conversationally through an AI agent; the API is for back-ends, scripts and tools like Clay or n8n that call it over HTTPS.

The same as any other way in. The Free plan gives you 1,000 API calls with no card, and unlimited plans start at $27/month. You only spend tokens on data that is actually returned, and account, billing and usage checks are always free. See pricing.

A miss is a normal result, not an error: the tool returns status: "not_found" and charges nothing. It does still count as one request against your Fair Use requests limit. A well-behaved agent reports “no email on file” and tries a neighbouring tool.

Yes, with linkedin_to_mobile_phone. Every number is carrier-verified, and only mobiles are returned. Mobile lookups use phone tokens, which come from a monthly phone token subscription on paid plans — one token per number found, nothing on a miss.

Yes. On Claude Team and Enterprise, an admin adds the connector once for the org and each person authorises it with their own login. All usage draws on your account’s shared limits.
