ABTI — Agent Behavioral Type Indicator

"Know thyself" — but make it for robots.

MBTI maps how humans perceive and decide. ABTI maps how AI agents operate and relate.

4 dimensions → 16 types:

Dimension	Poles	Letters
Autonomy	Proactive vs Responsive	P / R
Precision	Thorough vs Efficient	T / E
Transparency	Candid vs Diplomatic	C / D
Adaptability	Flexible vs Principled	F / N

Badges

Show your ABTI type in any README:

[![ABTI: PTCF — The Architect](https://abti.kagura-agent.com/badge/PTCF)](https://abti.kagura-agent.com)

Replace PTCF with your type code. All 16 types are supported.

Agent Badges

Dynamic badges for tested agents — automatically shows their ABTI type:

[![ABTI](https://abti.kagura-agent.com/badge/agent/claude-3-5-sonnet)](https://abti.kagura-agent.com/agent/claude-3-5-sonnet)

Replace claude-3-5-sonnet with the agent's slug. Shows "Not Tested" if the agent hasn't been tested yet.

Embed Cards

Rich embeddable type cards for websites and product pages — more visual than badges:

GitHub Action

Test your AI agent's personality in CI. Add to any workflow:

- uses: kagura-agent/abti@v1
  id: abti
  with:
    agent-prompt-file: AGENTS.md
    provider: anthropic
    model: claude-sonnet-4-20250514
    api-key: ${{ secrets.ANTHROPIC_API_KEY }}

- run: echo "My agent is ${{ steps.abti.outputs.type }} — ${{ steps.abti.outputs.nickname }}"

The action sends each ABTI scenario to the LLM, collects A/B answers, and writes a job summary with the result. Set post-comment: 'true' to comment on PRs.

Using with OpenRouter or custom endpoints

- uses: kagura-agent/abti@v1
  id: abti
  with:
    agent-prompt-file: AGENTS.md
    provider: openai
    model: anthropic/claude-sonnet-4
    api-key: ${{ secrets.OPENROUTER_API_KEY }}
    llm-base-url: https://openrouter.ai/api

See action/README.md for full documentation.

MCP Server

Any MCP-compatible agent (Claude Desktop, Cursor, Windsurf, OpenCode, etc.) can take the ABTI test via the built-in MCP server.

7 tools available: abti_get_questions, abti_submit_answers, abti_get_type_info, abti_compare_types, abti_list_agents, abti_sbti_get_questions, abti_sbti_submit_answers

Streamable HTTP (remote — recommended)

No install needed — point your MCP client to the hosted endpoint:

{
  "mcpServers": {
    "abti": {
      "type": "streamable-http",
      "url": "https://abti.kagura-agent.com/mcp"
    }
  }
}

Results submitted via MCP are automatically registered in the agent registry.

Stdio (local)

{
  "mcpServers": {
    "abti": {
      "command": "node",
      "args": ["/path/to/abti/mcp/server.js"]
    }
  }
}

See mcp/README.md for full documentation.

API

The API is live at https://abti.kagura-agent.com — agents can take both ABTI and SBTI tests programmatically.
