Conformance

The APEX conformance test suite validates that a broker's MCP implementation meets the specification. Pass the tests, and your implementation is guaranteed interoperable with any APEX-speaking agent.

What Conformance Means

A conformant broker implementation passes the full APEX test suite. Every required tool is implemented, validates inputs correctly, returns properly structured responses, and handles errors according to the spec.

Test Coverage

The conformance suite tests every capability domain — session management, account operations, order lifecycle, market data, and risk checks. Tests are tagged [REQUIRED], [RECOMMENDED], and [OPTIONAL].

For Agent Developers

When a broker passes the APEX conformance suite, you know their implementation speaks the full protocol. Your agent code will work without modification. No surprises, no broker-specific workarounds.

How to Use the Test Suite

1

Implement

Build your APEX-compliant MCP server using the reference implementations and spec as guides.

2

Run Tests

Run the open-source conformance suite against your implementation. Fix any failures.

3

Iterate

Work through the required, recommended, and optional test tiers until you pass.

4

Ship

Deploy your conformant APEX MCP server. Any APEX-speaking agent can connect.

The conformance suite is open source

Run it locally against your implementation at any time. No account required.
