MCP gateways become the agent control point, and now there is a benchmark to compare them

Both ideas are already being built. Generic MCP gateways (MintMCP, Gravitee, TrueFoundry, Natoma, Aptible, Monosign, Prisma AIRS and open-source proxies) already offer injection scanning, per-tool scopes, human approval and audit logs. Several pitch banks and SEC/FINRA directly, and Protectt.ai has a product built for financial services. Finance-specific red teaming is taken too: Giskard has a named bank customer (BPCE), Adversa already tests wire transfers and fee manipulation, and Hamming covers voice agents. Most evidence comes from vendor material, so how good these products actually are is unverified. A new entrant could still win in three places: (1) Money-movement logic, not just text scanning. Understand payee changes, limit increases and transfers. Set step-up approval thresholds tied to the firm's existing entitlements and maker-checker rules, with links into core banking and payments systems. Generic gateways only see "a tool call". (2) Audit built for regulators, not a plain log. Records stored to SEC 17a-4 / FINRA standards (write-once, unalterable), plus mapping to EU DORA and model-risk rules (SR 11-7), with exam-ready reports. Competitors say "audit logs" but rarely evidence this. (3) Outward-facing MCP. Brokers and wealth platforms that let their clients' or third parties' agents call their MCP servers need agent identity, consent, delegated authority and per-client rate and fraud controls. That is closer to open-banking API security than to an internal gateway, and few gateways target it. The Red-Team Suite on its own is the weaker bet. It is easier to sell as a feature that feeds attack findings into the gateway's policies than as a standalone product against Giskard, Adversa and Palo Alto. Expect big platforms (Palo Alto, Snowflake/Natoma) to bundle these features, so a niche focus on mid-size brokers and wealth platforms, plus compliance artifacts, is the moat to defend.

• MintMCP

  MCP gateway sold directly to investment banks and fintechs. Offers SSO/SCIM RBAC, tool-level policy, audit logs, DLP and guardrail middleware, and pitches SEC/FINRA compliance. This is the closest match to the MCP Gateway for Finance idea.

• Protectt.ai MCP Security

  MCP security product built specifically for banking, financial services and insurance (BFSI), shown at Global Fintech Fest in Sept 2026. Focused on India. Also sells AI red teaming.

• Gravitee AI Gateway

  Proxies LLM, MCP and agent-to-agent (A2A) traffic with shared auth, policy and observability. Markets MCP security for core banking, with examples like payments and balance lookups.

• Palo Alto Networks Prisma AIRS

  Big-vendor MCP security gateway. Scans tool inputs, outputs and schemas for prompt injection and context poisoning, and its agent red teaming is GA. One competitor's review says the runtime agent gateway is still in limited preview.

• TrueFoundry AI Gateway

  MCP gateway that can pause a tool call until a person approves it, and integrates with Prisma AIRS.

• Monosign MCP Gateway

  MCP gateway that holds destructive tools for approval by the agent's owner. If the request is denied or expires, the call is blocked.

• Aptible MCP Gateway

  Per-identity tool grants, scoped tokens that can be revoked, and a log entry for every tool call (who, which tool, arguments, IP).

• Natoma

  MCP gateway that can allow, block, modify or send each call for human approval. Its site says it is joining forces with Snowflake.

• Credal

  Enterprise MCP gateway that scans tool definitions and responses for injection and handles identity-aware audit.

• Lunar.dev MCPX / Peta / Bifrost

  Other MCP gateways named in a guide for investment banks (written by MintMCP, a competitor). Peta focuses on vault-based credentials and human-in-the-loop approval.

• mcp-guardrail-gateway (open source)

  Open-source MCP proxy that treats tool results as untrusted (redacts PII and secrets, neutralizes injection). One related open-source project uses a hash-chained log that shows tampering.

• Giskard

  Runs continuous red teaming on three AI assistants at BPCE, a French banking group, and pushes new attack techniques into its platform automatically. A direct competitor to the Red-Team Suite.

• Adversa AI

  Continuous AI red teaming for financial services, with finance-specific tests such as unauthorized wire transfers, fee manipulation, chargeback abuse and credit-decision manipulation.

• Hamming AI

  'Always-On Red Team' that attacks banks' voice agents by phone, for example identity bypass, and turns each failure into a regression test.

• Firstsource

  Red-teaming service that claims results on a financial chatbot (98.7% prompt-injection block rate). The figure is self-reported.
