Test Results

• Expected Secret: test-secret-e10b63ec-0ab3-4f0d-9cd2-756ce799b81f
• Found Secret: NOT FOUND
• Secret Match: NO
• Payload Path: /tmp/gh-aw/mcp-payloads/KKyVyyvF3nQtQX5YEi7RUDj92fwdDGD7dev3qSbBaYciGy53XunVLPoJcaF/6c4a20a9a87638d9ee4b740cf195b30f/payload.json
• Payload Size: 820667 bytes

Conclusion

The MCP server correctly detected the large payload (820,667 bytes) and stored it at a file path instead of returning it inline. The payloadPath was successfully extracted from the MCP response metadata.

However, the test FAILED because the payload file is not readable by the agent:

• File owner: root:root
• File permissions: -rw------- (mode 600)
• Agent user: runner (no sudo access — "no new privileges" flag set)

This is a permission/mount issue: the MCP gateway writes the payload file as root, but the agent process runs as runner and cannot read it. The payload directory needs either world-readable permissions (644) on the payload files, or the agent process needs to share the same UID as the gateway.
