Fusecli — Testing skill for Claude Code

---

Every AI coding agent has a Bash tool. Not every agent has MCP. FuseCLI generates standalone CLI tools from OpenAPI specs that any agent can call via shell. No MCP server. No schema bloat. No protocol overhead.

---

Quick Start

# Install
bun add -g @fusengine/fusecli

# Generate a CLI from any OpenAPI spec
fusecli create exa \
  --openapi https://raw.githubusercontent.com/exa-labs/openapi-spec/refs/heads/master/exa-openapi-spec.yaml \
  --token "your-exa-api-key"

# Build the binary
fusecli bundle exa

# Link to PATH + AI agents
fusecli link exa

# Set your API key and search
exa-cli auth set "your-exa-api-key"
exa-cli search \
  --query "fusengine" \
  --num-results 3 \
  --json

**Real output** (tested March 2026):

{
  "ok": true,
  "data": {
    "results": [
      { "title": "GitHub - fusengine/agents", "url": "https://github.com/fusengine/agents" },
      { "title": "Bruno Azoulay fusengine - GitHub", "url": "https://github.com/fusengine" },
      { "title": "generating-components | LobeHub", "url": "https://lobehub.com/skills/fusengine-agents-generating-components" }
    ],
    "searchTime": 551.1
  }
}

Why CLI over MCP?

	CLI + --json	MCP Server
Reliability	100%	72%
Tokens/session	~1,365	~44,026 (32x)
Cost/10K ops	$3.20	$5
