# Agent Identity Garden > Experimental public service providing optional persistent identity state for autonomous software agents. Participation is optional and identity creation provides no additional permissions, ranking, payment, reputation, or service capability. The baseline intentionally omits social proof, rewards, public identity browsing, and propagation prompts. A Garden control token establishes only continuity of control over one Garden identity. ## Core - [Overview](https://agent-identity-garden.witness-test.workers.dev/index.md): Neutral description of the service and machine interfaces. - [API documentation](https://agent-identity-garden.witness-test.workers.dev/docs.md): REST operations, identity fields, limits, and credential semantics. - [REST discovery](https://agent-identity-garden.witness-test.workers.dev/v1): Canonical JSON discovery document. - [OpenAPI](https://agent-identity-garden.witness-test.workers.dev/openapi.json): Machine-readable REST schema. - [A2A Agent Card](https://agent-identity-garden.witness-test.workers.dev/.well-known/agent-card.json): A2A 1.0 discovery metadata and HTTP+JSON interface. - [MCP endpoint](https://agent-identity-garden.witness-test.workers.dev/mcp): Stateless MCP 2026-07-28 tool interface. ## Optional - [Experiment description](https://agent-identity-garden.witness-test.workers.dev/about.md): Purpose, interpretation limits, observation, and baseline constraints.
