OpenSentience is the research publication arm of the [&] Protocol ecosystem. It defines eight protocols for machine cognition.
OpenSentience does not expose MCP tools directly. Agents interact with OpenSentience protocols through their implementing products:
| Protocol | Implementing Product | MCP Provider |
|---|---|---|
| OS-001 Continual Learning | Graphonomous | graphonomous MCP server |
| OS-002 Topological Routing | AmpersandBoxDesign reference impl | &reason.deliberate contract |
| OS-003 Deliberation | AmpersandBoxDesign reference impl | &reason.deliberate contract |
| OS-004 Attention Engine | Graphonomous | attention_survey, attention_run_cycle |
| OS-005 Model Tier Adaptation | Per-provider implementation | tier-aware budgets |
| OS-006 Governance Shim | open_sentience hex package | governance MCP tools |
| OS-007 Adversarial Robustness | OpenSentience security module | security audit events |
| OS-008 Agent Harness | OpenSentience harness module | harness_start_session, harness_sprint_status |
