Developer tools servers add docs lookup, code search, package data, and execution to coding agents. Install the few you need; every extra server adds tool definitions to the context. 761 published MCP servers match this ranking. The highest trust scores right now are dep-diff-mcp at 67, CGIS Code Graph at 67, hamn at 66. The order is the published trust score: registry record, license, maintenance, popularity, documentation, and security signals. Featured slots, when an editor sets them, are labeled and do not change the score. Best developer tools MCP servers is not a paid placement.
