Compare/Head to head
Same facts, side by side: starting price, free tier, MCP, API and what each one is actually built for.
Starting price
$49/mo Free trial
B2B company, employee, and jobs data APIs with official MCP. 7-day trial (2,000 credits); Mini is $49/mo.
Where Coresignal fits
$39/mo
Developer API that pulls public professional profiles and company pages live at request time, so titles and headcounts are current rather than last quarter's, with email and phone included where they are publicly available. Plans start at $39/mo for 1,000 credits, a basic profile costs 1 credit, and a hosted MCP server lets Claude or ChatGPT call it directly. Best for teams that can wire an API, not recruiters who want a point and click search screen.

Coresignal
Stands out: A real data API plus MCP at $49 Mini: this is enrichment infrastructure, not a Chrome overlay.
Watch out: Mini is 2,500 credits. Starter is $199 and Pro $499. Treating $49 as production volume will fail in week two.
Not the right fit for
Datamagnet
Stands out: Data is fetched from the live profile at the moment you ask rather than from a stored snapshot, and the credit price per call is published endpoint by endpoint, down to 1 credit for a basic person or company profile. The MCP server is unusually complete for a data vendor: 17 tools, OAuth sign in so no key is pasted into the AI app, and every tool states its credit cost before it runs.
Watch out: This is an API, not an app: there is no search interface or sourcing workflow, so someone has to build on it or use it through Clay, n8n or an AI assistant. Rate limits are low on self serve plans (10 to 30 requests a minute), and the richer calls such as post engagement, activity and ICP search pages cost 10 credits each, so a search heavy month burns credits ten times faster than plain enrichment. Emails and phone numbers come back only where they are publicly available, and the vendor does not describe a deliverability check.
