Free MCP server · runs on your machine

Give your AI honest pricing data for marketing, sales and e-commerce software

AI assistants guess at software prices, or repeat the vendor’s marketing. The Honest Atlas MCP gives Claude, Cursor or any MCP client the same hand-researched dossiers that sit behind every review on this site: the price as read on the vendor’s page on a stated date, the honest catch, who the tool is genuinely for, and who should skip it. No invented numbers. 44 tools reviewed on Marketing & Sales Software are in it, alongside the rest of the network’s 430+ dossiers.

Install, 30 seconds

Claude Code: one download, one command.

Claude Desktop or Cursor: download atlas_mcp.py, then add it to your MCP config.

Requirements: Python 3.8 or newer, nothing else. About 300 lines you can read yourself. It fetches the public dossier feed once a day and runs entirely on your machine: no account, no tracking, no key.

Then ask your AI things like

“Compare ActiveCampaign and Brevo for a 10,000-contact list, including the add-ons.”
“Which cold-email tools here are metered by mailbox rather than by seat?”
“What is the honest catch with Leadfeeder before I buy the entry plan?”
“Find Shopify apps in this dossier with a real free plan, not a trial.”

Tools from this site the server knows

Every one of these has a review on Marketing & Sales Software; the dossier your AI reads is the same one the review was written from.

What it is, and what it is not

One server for six sites. The MCP is published on AIBuilder Marketplace and serves the whole network’s corpus, so there is nothing separate to install for this site. Dated, not live. Prices carry the date they were read; the server does not scrape vendors in real time. Disclosure. Dossiers include our affiliate links, marked as such in the data; a sign-up through one may earn us a commission at no cost to you, and it never changes the verdict. Dossier data is CC BY 4.0.
