Free100Leads MCP

This MCP server provides read-only access to B2B contact database coverage information. It allows agents to list available countries, industries, company sizes, and US states, check if specific combinations are covered, and understand the free allowance mechanics without requiring authentication.

Endpoint and access

No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Free100Leads is a B2B contact database searchable by country, industry, company size and job title, with a daily allowance for any visitor. list_coverage returns the countries, industries, company-size bands and US states available. check_coverage says whether a combination of those is covered and returns a link to claim contacts for it on the site. how_it_works describes the daily allowance and what a record contains. This server returns coverage only, never contacts or record counts.

list_coverage — Countries, industries and sizes covered
Advertised by the server during the last successful anonymous check.
Advertised read-only

The countries, industries, company-size bands and US states Free100Leads has B2B contacts for. Use it to answer "do you cover X" questions and to resolve a name before check_coverage. Returns lists only; it never returns record counts or contacts, which are on the site.

check_coverage — Check a filter combination
Advertised by the server during the last successful anonymous check.
Advertised read-only

Whether a combination of country, industry, company size and US state is covered, with the canonical names and a link to that search on the site. Use it for "do you have fintech contacts in Germany" or "small companies in Texas". Limitation: says covered or not; the number of matching records and the records themselves are shown on the site, not here.

What Free100Leads is, what a record contains, how the daily allowance works, and the links to the site, the API docs and the removal form. Use it when the user asks how to get contacts from Free100Leads. Returns text and links only.

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http free100leads-mcp https://free100leads.com/api/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add free100leads-mcp --url https://free100leads.com/api/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable free100leads-mcp in your MCP settings.
Cursor configuration
