Model Context Protocol (MCP) server for Apollo.io API integration
Nothing to run from here
Leadquasar is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.

Installation
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine and nothing runs on ours: this server answers at its publisher’s own address, and what you install is the connection straight to it.
Claude Codedeclared by this listing
This is a public server: it answers at its publisher’s own address and this marketplace is not in the path. Claude Code registers it in one command; --scope user makes it available in every project. The transport below is http, as the publisher's own manifest declares it.
claude mcp add --scope user --transport http leadquasar-mcp https://leadquasar.com/api/mcpReconnect, or start a new session, and the tools appear in the model’s tool list.
Free on mcprush, and it answers at its publisher’s own address: this marketplace is not in the path, so there is no key of ours to hold and no card to add.
What it writes
One config entry pointing straight at the publisher’s own address — this marketplace is not in the path, and nothing from this listing executes on your machine.
What you approve
3 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.

Count verified B2B businesses in the LeadQuasar database matching an industry, country, US state and/or city, with how many have an email address and a phone number. Use this to answer questions like 'how many managed service providers are there in Texas', 'how many dentists in Chicago have a business email' or 'how many movers are there in London' (country GB). Returns real counts from 8.7 millio
| Parameter | Type | Required | Notes |

| country | string | no | Country, as an ISO code ("US", "GB", "CA") or a name ("United Kingdom"). Omit to count every country. Coverage outside the US is much smaller. Countries with data: United States (US), United Kingdom ( |
| state | string | no | US state, either full name ("Texas") or two-letter code ("TX"). US only. |
| city | string | no | City name, e.g. "Chicago", or "London" with country GB. |
| no_website | boolean | no | true = only businesses whose Google Maps listing shows no website of their own (read from the listing; a Facebook-only listing counts as none). For questions like 'plumbers in the UK without a website |
Return a sample of matching businesses with industry, location and data-quality signals. Contact details (name, company, email, phone, address) are never returned by this tool — it shows what exists and how reachable it is, not who to call.

—Grade not published
No rule-by-rule report on file for this release
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.
This listing is an address its publisher runs, and you connect to it directly — this marketplace is not in the path. The scanner reads packages and public source, and an address is neither. So there is no grade — not a withheld one, an unmeasured one.
Release history
This is an address its publisher runs: which release it serves is theirs to choose, so there is nothing here to pin. The history below is for reading; the current release on file is 1.0.0.

Who can review
One review per account, from a signed-in account that does not publish this listing. Nothing else is asked — you can say what you think before you install it. Publishers can reply once per review, and a review can be edited or deleted by whoever wrote it.
Sign in to write one
Any signed-in account that does not publish Leadquasar can review it, once — before installing it or after. A review from an account that has installed it is marked as one.
No reviews yet
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes a signed-in account that does not publish it, and nothing else.
