Native DRE
Decision Runtime Engine
MCP interface
Coming soon

A common policy interface
for agents.

MCP (Model Context Protocol) is one distribution surface for DRE's compile, validate, and audit flows — not the only runtime path. Self-hosted customers call DRE directly from the inference loop; MCP is how DRE reaches agent frameworks that already speak it.

The local CLI below runs the same compile and judgment loop against the two adapters shipping today: self-hosted residual and Vertex.

Local example

Run the compile and judgment loop on your machine.

SHELL · local
self-hosted adapter
# 1. compile a policy for a local llama.cpp target
$ dre compile \
    --policy ./policy.md \
    --target llama3.1-8b-instruct \
    --adapter residual \
    --out ./build/

# 2. run the local agent loop with DRE in the critical path
$ dre serve --adapter residual --bundle ./build/

# 3. agent submits a claim — DRE validates it against policy

The through-line

DRE is the policy layer agents run under — not a framework, not a rules engine, not a checklist.

MCP is one distribution surface. The adapters are the real story — each one maps a compiled policy into whichever enforcement point the provider exposes.
