Let your agent find its tools
Add Koskamo to your agent to find official MCP servers for a task, inspect access requirements, and get setup links. Public discovery needs no key.
How listings and verification work
Remote listings are live-checked and re-checked weekly. Local packages are validated from their attributed registry or catalog source and are never executed by Koskamo. Community and vendor evidence are labelled separately.
Access labels describe remote connection and discovery. Individual tools may require accounts, credentials, permissions, or payment. Registry membership and endpoint checks are not security audits.
