An MCP server is a process: read files, query a database, search the web. A skill is text: order, checklist, and forbidden moves.
MCP alone gives the agent hands without your team rules. Skills alone give steps without access to the repo.
Start with one filesystem or version-control MCP, then one matching skill such as open-a-PR or review-code.
Pick one entry with install metadata from each directory here. That is safer than wiring a dozen unknown servers.
