MCP + Skills

The agent ecosystem that ships through Anvat.

12 Model Context Protocol servers + 6 Claude Skills verified end-to-end against models routed through api.anvat.app. Anvat doesn't modify tool-use semantics — if it works against the upstream provider, it works against us.

What this page proves: the entire MCP / Skills ecosystem is portable. You can switch from direct Anthropic to Anvat without losing a single server or skill.

Same wire protocol

MCP tool-call format is preserved byte-for-byte. Server discovery, capability negotiation, and SSE streaming all round-trip through Anvat unchanged.

Skill auto-discovery preserved

Claude Skills in ~/.claude/skills are discovered by claude-code at session start regardless of where the API endpoint resolves. Anvat is just a base-URL change.

Per-tool billing visibility

Every MCP-driven tool call shows up as its own line in your activity log with the model + tokens + cost, so you can see which tool is burning the most spend.

Built an MCP server or Skill?

We're actively curating. If you have an MCP server or Claude Skill that solves a real problem and you've tested it against Anvat-routed Opus/Sonnet/Haiku, email hello@anvat.app with the repo + a 1-sentence pitch. We'll verify it on our side and add it within a day or two.
