H-1B Sponsor is an MCP server listed in the public MCP registry as io.github.janishkumar/h1b-sponsor-mcp. Is this company still sponsoring H-1Bs and green cards? Trends from DOL and USCIS filings. This page covers its PyPI package (h1b-sponsor-mcp).

### Is the H-1B Sponsor MCP server safe to use?

H-1B Sponsor scores 69 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the H-1B Sponsor MCP server expose?

H-1B Sponsor exposes 6 tools: company_sponsorship, compare_companies, top_sponsors, salary_range, find_employer, data_info. Their descriptions and schemas cost roughly 660 tokens of context every time the server is loaded.

### Is the H-1B Sponsor MCP server still maintained?

H-1B Sponsor is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the H-1B Sponsor MCP server under?

H-1B Sponsor declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
