Interact with AdCP (Ad Context Protocol) advertising agents over MCP or A2A protocols. Use when the user wants to call AdCP tools (get_products, create_media_buy, sync_creatives, etc.), discover an agent's capabilities, run protocol compliance tests, look up brands or properties in the AdCP registry, manage saved agent aliases, or debug agent responses. NOT for general HTTP/REST API calls. Requires @adcp/sdk (npm).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# AdCP CLI
Use `adcp` (or `npx @adcp/sdk@latest`) to interact with AdCP advertising agents, run compliance tests, and query the AdCP registry.
## Quick start — zero config
Built-in test agents work immediately with no setup:
```bash
# Try AdCP right now
adcp test-mcp # List tools on the MCP test agent
adcp test-mcp get_products '{"brief":"coffee brands"}' # Call a tool
adcp test-a2a get_products '{"brief":"coffee brands"}' # Same thing over A2A
# Run compliance tests
adcp test test-mcp discovery # Test tool discovery
adcp test test-mcp full_sales_flow # Full media buy lifecycle
```
Built-in aliases (no setup needed):
- `test-mcp` — Public test agent via MCP (pre-authenticated)
- `test-a2a` — Public test agent via A2A (pre-authenticated)
- `test-no-auth` — MCP without auth (demonstrates auth errors)
- `test-a2a-no-auth` — A2A without auth
- `creative` — Official creative agent (MCP, requires `--auth` or `ADCP_AUTH_TOKEN`)
## Calling agent tools
```bash
adcp <alias|url> [tool-name] [payload] [options]
```
### Discover tools (omit tool name)
```bash
adcp https://agent.example.com

How to install
mdr add adcontextprotocol/adcp-client/adcp@sha256:22c8be92a7d8f4dfThe line at the top of this page pins the label git:20261001.807d8cf, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
