osv_list_ecosystems
shallowio.github.cyanheads/osv-advisory-mcp-server · Verify this server
Return the list of supported ecosystem identifier strings for use with osv_query_package and osv_query_batch. Ecosystem strings are case-sensitive exact matches — passing "pypi" instead of "PyPI" returns an error from the API. Use this tool to discover valid ecosystem strings before querying, or to verify an ecosystem identifier from a lockfile format. The list is static (maintained from the OSV schema spec) and may occasionally lag newly added ecosystems.
