Integrations

EVE + CrewAI

Compatibility: Experimental integration — structurally implemented but not included in the supported release-candidate adapter matrix.

The CrewAI adapter routes tool calls made by crew agents into EVE's governance composition root so CoreGuard makes a deterministic ALLOW / BLOCK / MODIFY decision before a tool executes. The adapter is structurally implemented, but CrewAI was not installed during release-candidate validation, so it was not validated against a pinned live version and is marked UNTESTED / experimental. Only the generic adapter is SUPPORTED.

How governance works here

Each agent's tool call is submitted to EVE before it runs. No LLM is in the decision path.

from eve_coreguard import CoreGuardClient

client = CoreGuardClient(api_key="eve_sk_...")  # hosted CoreGuard API

result = client.evaluate(
    request_id="req-001",
    tenant_id="tenant_demo",
    proposed_action={"type": "send_email", "to": "[email protected]", "subject": "Update", "body": "..."},
    model_output={"decision": "send", "confidence": 0.9},
    context={"principal_id": "crew_outreach", "session_id": "sess_71af"},
    policy_set="lending_v1",
)
# ALLOWED -> execute; BLOCKED -> do not call the tool; MODIFIED -> use modified arguments.

eve-coreguard (0.2.7) is published on PyPI. Entry point: from eve_coreguard import CoreGuardClient.

Hardened alternative

This adapter is wrapper-enforced: an agent that calls the underlying tool directly is not intercepted. For a boundary a direct call cannot route around:

Put tools behind a restricted server-side tool registry reachable only through the governed path.
Proxy tool execution through a sidecar so governance runs out-of-process.
Apply network enforcement so tool endpoints are only reachable via the governed path.
For MCP tools, route through the MCP gateway, which binds the approved request to the executed request (see mcp.md).

Readiness

This adapter: experimental (UNTESTED against a pinned live CrewAI version; wrapper-enforced).
Generic Python adapter: SUPPORTED.
EVE SDK core: RELEASE CANDIDATE WITH EXCLUSIONS.

Limitations

Not validated against a pinned live framework version.
Wrapper-enforced: bypassable by a direct underlying-tool call. Hard enforcement requires a gateway/sidecar or restricted server-side tool registry.
Hosted mode requires a reachable endpoint; embedded governance is the EVE service.
Evidence verification proves authenticity and integrity, not decision correctness; independent verification needs the ECDSA P-384 public key.
