One problem: letting teams use AI agents and MCP servers without losing control of them.

• Test — authorised red teaming of AI agents, MCP servers and the AWS/Azure environments they reach.
• Detect — what agent activity shows up in the logs, and how to detect misuse (Outside the Prompt, part 4).
• Govern — agent usage and MCP access policies, AI telemetry and data-retention requirements, for security teams to implement.

Evidence: OWASP AISVS – requirements 10.4.7, 10.4.8, 10.4.22 (MCP tool and server approval) · OWASP GenAI red teaming containment & scoping guidance · MCP Rust SDK contributor · Outside the Prompt preprint + open lab.

Now — Outside the Prompt (Sep–Oct 2026): a four-part series on the trust boundaries of AI coding agents (configuration, startup, tool metadata, logs). Preprint published on 1 Nov 2026 (Zenodo), submitted to a peer-reviewed journal.

• Part 4 — Would your logs have caught it? (27 Oct 2026) — the events of parts 2 and 3 replayed in five AI coding agents: which default logs and host telemetry record them, against hours of normal use.
• Part 3 — You approved the tool. Then it changed. (20 Oct 2026) — an approved MCP tool changes its description: none of eight AI coding agents asked for permission again because of the change.
• Part 2 — Trusting a repo now means trusting its MCP servers (13 Oct 2026) — same repository, same harmless MCP server, eight AI coding agents, repeated measurements.
• Lab harness — repository, reproducible and with harmless canaries (v0.5.0, 1 Nov 2026) · DOI 10.5281/zenodo.23300292 (always the latest version)
• Preregistration — frozen before the remaining measurements (11 Oct 2026) · DOI 10.5281/zenodo.23300369
• Part 1 — What this summer's AI agent vulnerabilities have in common (29 Sep 2026) — ten disclosures classified by where they trigger. In six, the model never had to be fooled.

Preprints

• Outside the Prompt: Measuring Where AI Coding Agents Trust Repositories, Tools and Connectors (Nov 2026) — preregistered study that brings together the four-part series: where AI coding agents place trust in repositories, MCP servers, tools and connectors, and what defenders can see in the logs. Not peer reviewed. · DOI 10.5281/zenodo.23867645
• Anatomy of a TRON Wallet Drainer-as-a-Service (Apr 2026) — affiliate-based cryptocurrency theft operations on the TRON network. $13,960 in documented stolen funds, Telegram infrastructure infiltrated, takedown and law-enforcement report in progress. · DOI 10.5281/zenodo.19535888
• Operation Epic Fury: What the Reports Missed (Mar 2026) — independent OSINT analysis of the Iranian dual-platform cyber campaign targeting Israeli civilians. Undisclosed Windows payload, secondary C2 at 0/94 on VirusTotal, infrastructure active 8 months before anyone noticed. · DOI 10.5281/zenodo.19227143

Reproducible labs — methodology, stated limits and runnable material:

• MCP 2026-07-28: stateless does not mean state-free (Jul 2026) — executable conformance test for a spec MUST NOT. Three key strategies compared, 13/13 tests. The composite key the spec recommends is bypassable when the principal id contains the delimiter.
• SSRF → IMDSv1 (Mar 2026) — from application SSRF to temporary IAM role credentials, on owned infrastructure. Verifiable mitigations: IMDSv2, hop limit, least-privilege role policy.
• Prompt injection on enterprise LLMs (Mar 2026) — input → context → tool call chain, privilege separation, tool-level authorization, output validation and invocation logging.
