Tiger Cloud + AI Agent via Tiger CLI and MCP (GHW Hacktoberfest)

Integrating Tiger Cloud with My AI Agent via Tiger CLI and MCP

For Global Hack Week: Hacktoberfest I completed the Tiger challenge: Integrate Tiger Cloud with your AI Agent with the Tiger CLI and MCP.

What I built

Not an app — an agent-ready database setup:

• Installed Tiger CLI v0.26.0 on Windows (irm https://cli.tigerdata.com/install.ps1 | iex)
• Authed with tiger auth login (OAuth, project New Project)
• Created a free Tiger Cloud service:
  • Name: ghw-hacktoberfest-agent-db
  • Type: TIMESCALEDB, Region: us-east-1, Status: READY
  • Verified with tiger service list and tiger db query -c "SELECT version();" → PostgreSQL 18.6
• Wired Tiger MCP to my agent (OpenCode) in opencode.json:

"tiger": { "command": ["tiger", "mcp", "start"], "type": "local", "enabled": true }

• Restarted the agent so the tiger MCP server loads (service_list, service_get, db_query, db_schema, search_docs, view_skill, + hypertable skills)

Why MCP + CLI

• CLI = explicit, scriptable control (tiger service create/list, tiger db query/psql)
• MCP = same operations as typed tools for the agent, plus docs search and best-practice skills (schema design, hypertable setup, migration planning)
• Both share one login, so anything I do in terminal the agent can do too

How I verified

1. tiger mcp list shows 30 tools/prompts
2. tiger db schema connects to the new service
3. Dashboard shows the service READY: https://console.cloud.tigerdata.com/dashboard/services/pphbkrfp6g
4. Submitted to GHW: Hacktoberfest challenge with dashboard + CLI screenshots

Takeaway

One binary gives you both interfaces. If you use OpenCode/Cursor/Claude Code and your client isn't in tiger mcp install, manual config with tiger mcp start works fine. For shared/prod DBs, consider tiger config set read_only prod.
