Map must-have capabilitiesList the workflows in MCP you cannot drop during migration.
Verify the licenseConfirm it fits your use, distribution, and compliance model. Browse license briefs.
Run a proof of conceptTest real data, integrations, clients, and failure modes. Use Compare for side-by-side checks.
Plan ownershipAssess upgrades, backups, support, and an exit path. Read when self-hosting is worth it.
Browse Awesome [MCP Servers](/projects/awesome-mcp-servers), then verify each repo. Popular categories: filesystem, git, browsers, databases, and docs search. Prefer maintained projects with clear permissions.
Goose, Continue, Open WebUI, and other agent/IDE shells increasingly speak MCP or equivalent tool protocols. Match the client to chat vs IDE vs autonomous agents.
Open source makes review possible, but power tools are still dangerous. Allowlist servers and assume any shell/file server can damage a machine if misconfigured.
Narrow the same alternatives by search, license, tags, or self-hosting signals when you need a tighter shortlist.
