What the publisher says

Connecting AI agents (like Claude or ChatGPT) to live trading APIs introduces massive security and compliance risks. Agent Provost solves this by acting as a secure, zero-trust Model Context Protocol (MCP) proxy specifically designed for the Alpaca trading API. It sits directly between your AI and your brokerage account, ensuring that LLMs can only execute trades within strict, pre-defined boundaries.

Built for fintech developers and algorithmic traders, Agent Provost features a hot-reloadable Rules Engine that enforces maximum trade notionals, share limits, and explicit symbol allowlists or blocklists. It includes robust rate limiting to prevent runaway AI loops and API bans.

Security is baked into the architecture. The appliance is 100% stateless, pulling ephemeral credentials into a secure RAM disk on every boot. For compliance and auditing, all AI trading requests and system actions are immutably logged to an AWS S3 bucket with Object Lock (WORM) enabled, ensuring a tamper-proof audit trail of every AI decision.

Reading the score

Disclosure · how many sources corroborate it

NoneNo source has it. Shown red, because Unknown means Unknown.
1 sourceA single place has it. A listing and its certification page and policy docs on one marketplace count as one source.
2+ contestedTwo or more sources cover it but they do not agree. The disagreement is shown, never dropped.
2+ agreeingTwo or more genuinely separate sources agree: another marketplace, or an outside record.
Steps below are possible but not automated yet, so today they sit open.
SettleTop confirmedSettleTop confirms it directly.

Evidence · what kind of evidence backs it

NoneNo source discloses it.
PublicPublicly available info, such as reviews, listing age, or vendor firmographics like legal entity and headquarters.
Vendor statedThe vendor's own claim on its marketplace listing, website, or policy documents.
Self-attestedThe vendor's self-attested certification or operator program, a marketplace program rather than an independent audit.
Steps below are possible but not automated yet, so today they sit open.
Vendor providedThe vendor hands SettleTop the underlying material, such as an SBOM or a data policy.
Vendor attestedThe vendor signs an attestation to SettleTop.
SettleTop verifiedSettleTop verifies it directly.

The SettleTop steps above are possible but not automated yet, so today they sit open and a perfect 10 is out of reach. Open information like firmographics and reach has fewer steps to climb, so it sits a little higher for the same visible evidence.

Information shown here reflects the best available information at the time of assessment and may be incomplete, outdated, or subject to change. It should be independently verified before being relied upon for any decision. SettleTop is not liable for any errors, omissions, or decisions made in reliance on this information.
