Best dev MCP servers
We tested 43 dev servers: 33 are ranked, 2 failed the handshake and are listed after them, and 8 aren't ranked: Git-only (pinned) listing: always held from rankings; deprecated; no passing tool call and under 50 GitHub stars; no passing tool call; no public repo. Short answer: UI5 MCP (100/100). This list includes paid and keyed servers; servers that need a key are labelled, and we have not tested any of them with real credentials.
Last tested 2026-11-11
How we test: methodology. Context cost: lowest context cost MCP servers. Not tested by us: security, output quality, and behaviour with real credentials.
8 servers tie at 100/100. Ties are broken in a fixed order: more passing real tool calls, then name A to Z. Order here: UI5 MCP (3 passing real calls); amCharts 5 MCP (official) (2 passing real calls); Git (reference, Python) (2 passing real calls); GraphQL MCP (enhanced) (2 passing real calls); Kubb MCP (2 passing real calls); MUI MCP (official) (2 passing real calls); Repomix MCP (official) (2 passing real calls); SAP Fiori MCP Server (1 passing real call).
