## Which one, for what

### Agno (BB)

Good for: Python teams that want agents, teams and workflows plus a self-hosted server with REST, MCP, approvals and scheduling in one package.

Ahead on:
- Agent ergonomics, 76 against 70
- Transparency & trust, 83 against 68

Watch for: Usage telemetry is on by default and sends session, run and agent identifiers unhashed. Prompts and outputs are not sent

### Agent Development Kit (ADK) (BB)

Good for: Teams on Google Cloud or working outside Python, and for anyone who wants approval, guardrail callbacks and evaluation in one framework.

Ahead on:
- Security & auth, 92 against 64
- Payments & pricing, 60 against 50

Also in its favour:
- No key needed to call it

Watch for: Two critical CVEs in 2026, one of them in tool confirmation itself

## Verdicts

**Agno.** An Apache 2.0 Python agent framework at 3.1.1 with an MCP client, tool confirmation and admin approvals, a durable job queue and 25 stable releases in 90 days. Usage telemetry is on by default with unhashed identifiers, and three high or critical advisories were published against it in the last 12 months, all fixed.

**Agent Development Kit (ADK).** Python, TypeScript, Go, Java and Kotlin. Two critical CVEs in 2026, one of them in tool confirmation itself.

## Before you call either

### Agno

1. Set AGNO_TELEMETRY=false before the first run, and pass telemetry=False to AgentOS and to each eval, which ignore the variable
2. Configure JWT_VERIFICATION_KEY with AgentOS authorisation switched on, or OS_SECURITY_KEY, before exposing AgentOS. With neither set, REST and MCP routes take no credential
3. Mark tools that write with requires_confirmation, and resume with continue_run once every requirement is resolved
4. Set tool_call_limit on agents. The default is None
5. Install extras for what you use, such as agno[mcp] for MCPTools and agno[os,mcp] for AgentOS with its MCP server

### Agent Development Kit (ADK)

1. Upgrade to 2.5.0 or later before relying on tool confirmation
2. Always pass tool_filter to McpToolset
3. Pin a 2.x minor and read the changelog's breaking section before each bump
4. Install the bigquery-analytics extra if you use pyarrow, since 2.7.0
5. Keep ADK Web off public interfaces, or run 1.28.1 or later at the least
