Vibocode Mcp

vibocode-mcp

Two tools instead of an API catalog. An MCP server that keeps the agent's context small and its reach long.

search  — finds the right endpoints and memory facts, returns compact signatures
run     — executes model-written Python in a sandbox: api.get(path) + vi.add/find/stats

The whole toolset is 217 tokens (o200k_base tokenizer). The same GitHub REST catalog — 1,272 endpoints — costs 79,525 tokens as plain MCP tools: a 366x difference. Slack's 174 endpoints: 42x. Measurements and reproduction commands are in Benchmarks.
