One of these can say no. The other can only recommend. That is the whole comparison, and everything below is a consequence of it.
Salt Code is a remote, hosted MCP server. Salt’s own public repo declares it plainly: "transport": "http" against https://salt-code.secured-api.com/mcp, bearer authentication. What it returns is security-policy guidance text for the model to read while it writes code — the OWASP API Top 10, MCP-authoring guidance, LLM-integration patterns, OpenAPI/Swagger compliance. Salt’s tagline for it is “Secure code. Every prompt.” (salt.security/getsaltcode) That is an accurate description of what it does: it makes the code your agent authors better.
MoorAI does not look at the code the agent writes. It looks at what the agent is about to do, and at what the developer is about to send. A PreToolUse hook inside the coding agent and an MCP stdio gateway in front of the tool servers see which tool is about to run with which arguments, and can stop it before it executes. The prompt going out is checked locally against a 67-threat matrix for secrets, PII and exfiltration patterns. Every decision lands as an ed25519-signed, content-free record. The agent is open source (AGPL-3.0).
These are not competing products. They are barely in the same category. Salt Code is a shift-left authoring aid; MoorAI is a runtime control plane for agent actions. A team could sensibly run both, and the honest half of this page — the nine rows where Salt Code covers ground MoorAI does not attempt — is below and is not padded.
Salt sells two different things, and this page compares the second one. The Agentic Security Graph is the enterprise API-security platform, and that comparison is spatial — gateway versus endpoint. It lives at MoorAI vs Salt Security. Salt Code is a different category with a different buyer: a developer who just got a free token by email and pasted a config block into their editor. If that is you, this is the right page.
The wedge is advisory versus enforcing — cooperative versus deterministic. Not privacy, not architecture, not feature count. Salt Code does not ingest your source code; its own FAQ says Salt sees the MCP tool calls, not your code. So “we’re more private” would be a weak and rebuttable argument, and we are not making it. The argument that survives contact with their documentation is much simpler: Salt Code cannot block anything, and says so.
salt-code.secured-api.com/mcp is live and token-gated — an unauthenticated MCP initialize returns 401, from an AWS API Gateway. To be precise about what that means: Salt sees the tool calls — the model’s description of what you are building — not your code. The operational consequence is availability, not confidentiality: no network, no policy, and tokens expire at 180 days, so coverage can lapse silently. MoorAI evaluates locally and fails closed.Read this before you read the tables. Both products say “MCP security,” and they mean opposite things. Salt Code’s MCP Security pack is guidance for authoring MCP servers securely — prompt injection via tool descriptions, tool poisoning, excessive tool permissions, insecure server configuration. It is advice, delivered as text, at the moment you write a tool definition. MoorAI’s MCP work intercepts live tool calls at runtime and blocks them — server allow-listing, per-tool argument rules, refusal before execution. Salt Code cannot see or stop a single MCP call at runtime. It is itself just another MCP server in the agent’s list. A reader who sees “MCP” in both columns will otherwise assume parity, and there is none.
Every row here follows from the same property: MoorAI sits at an execution boundary the agent has to cross, and Salt Code sits behind a tool the agent may or may not call. Nothing in this block is a criticism of Salt Code’s design — a policy-guidance MCP server is not supposed to be an enforcement point. It is a statement of what each one can and cannot do at the moment something goes wrong.
| MoorAI | Salt Code | |

| Can block an action before it executes | ✓PreToolUse hook | ✗returns guidance text only |
| Enforcement independent of model cooperation | ✓outside the model's discretion | ✗rules file asks the model to consult |
| Governs MCP tool calls at runtime (stdio gateway) | ✓allow-list + per-tool arg rules | ✗is itself an MCP server |
| Inspects what the developer sends — secrets, PII, exfiltration | ✓67-threat matrix, local | ✗out of scope by design |
| Reviews the model’s output, not just the prompt | ✓output review + redaction | ✗advises before generation |
| Shadow-AI discovery — agents, MCP servers, accounts on the device | ✓content-free inventory | ✗no endpoint presence |
| Works offline — and fails closed | ✓local evaluation | ✗remote endpoint; documented fail-open |
| Signed, tamper-evident decision record | ✓ed25519 per decision | —enterprise usage metrics announced |

| Self-serve credential revocation | ✓revoke in-product | ✗email security@salt.security |
This is the honest half, and it is nearly as long as the first. Salt Code does something MoorAI has no opinion about whatsoever: it makes generated code safer. MoorAI will happily let an agent write an endpoint with broken object-level authorization, because MoorAI is not looking at the code — it is looking at the shell command, the file read and the tool call. If your problem is “our AI assistants are producing insecure APIs,” MoorAI is the wrong tool and Salt Code is the right one.

These four are not scored, because scoring them would be dishonest. Both products use the same vocabulary and neither is misusing it — they simply operate at different moments in the life of an agent. Read the two cells, not a checkmark.
| MoorAI means… | Salt Code means… | |
|---|---|---|
| “MCP security” | Runtime interception. The stdio gateway sees a live tool call, checks the server against an allow-list and the arguments against per-tool rules, and refuses before execution. | Authoring guidance. Advice returned as text while you write an MCP server or tool definition — tool poisoning, excessive permissions, insecure transport, missing auth. |
| “Prompt injection” | Detection in the live flow. Injected instructions arriving via tool output, a poisoned rules file, or a cross-server toxic flow, caught as the agent runs. | A code-review category. Patterns in the code being generated that would permit injection — user input passed straight into a prompt, unsanitized model output. |
| “Secrets and PII” | What is leaving now. The prompt, paste or tool argument on its way out of the machine, blocked before it becomes egress. | What the code will do later. Guidance against PII in URLs, query-string authentication, and credentials in prompt context in the endpoint being written. |
| “Policy” | A rule evaluated against an action, producing coach, alert, block or justify — and a signed record either way. | A body of guidance returned to the model, which then decides what to do with it. Counted per pack, not per enforcement. |
A row we deliberately did not write. It would be easy to put MoorAI’s 67 threats next to Salt Code’s 40 policies and let the reader draw a conclusion. Those are different units and the comparison would be misleading in our favour: MoorAI’s are runtime detections that fire on an agent action, Salt’s are secure-design guidance topics returned as text. For the record, the public repo enumerates 33 named categories across four packs (10 API, 8 agentic, 7 LLM, 8 OpenAPI), the repo and setup page both say 40 active policies, and Salt’s enterprise pages describe 140+. No count on either side is a capability claim, so no count appears in a table row.
On “free”, two descriptions coexist. Salt’s launch press release says free access runs through an Early Access Program “available to the first 100 organizations to enroll”; the live product page describes Salt Code as free with no cap — “Actually free. No credit card.” (salt.security/getsaltcode) Both statements are Salt’s own and we are not going to resolve which is current — check before you plan a rollout around it. MoorAI’s community agent is free and AGPL-3.0; the code is the guarantee.
Where MoorAI is stronger. The moment of the action. An agent about to run rm -rf, read ~/.aws/credentials, or drive a local filesystem MCP server over stdio is not writing an API endpoint, so there is nothing for a code-guidance policy to advise on. That is the surface MoorAI owns: allow-list the server, constrain the arguments, block before execution, and land a signed, content-free record mapped to the OWASP LLM Top 10, NIST AI RMF, ISO 27001/42001 and the EU AI Act.
Where Salt Code is stronger. The code that ships. Salt has spent years on runtime API security and it shows in the policy packs — the OWASP API Top 10 rendered as things an assistant can apply while it writes, not as a report someone reads afterwards. Its CEO frames the goal as security policy travelling “with the code itself” (salt.security press release), and that is a real and different ambition from ours. Sixteen tested integrations, no endpoint agent, and coverage of cloud builders where MoorAI has nothing to install on.
Use both, honestly. Run Salt Code if your AI assistants are generating API surface and you want OWASP API and OpenAPI guidance applied at authoring time across a wide range of editors. Run MoorAI where those same agents have terminal, filesystem and MCP access, where the tool call has to be governed at runtime rather than recommended against, and where the evidence an auditor reads must contain no one’s prompt content at all. The failure modes they cover do not overlap.
Salt Code details are taken from Salt Security’s own public repository (github.com/Secful/saltcode, MIT), its product and setup pages, and its launch press release, checked in 2026; quoted phrases are Salt’s. Rows marked announced reflect capabilities Salt has published for its enterprise tier and which we have not independently verified as shipping. ◐ = partial — present but narrower than the other column. — = unconfirmed, not necessarily absent. MoorAI marks reflect shipped capability, and we are precise about its narrowness: full hook enforcement is on Claude Code today, with Codex and Copilot CLI detection-only, and the agent runs on macOS and Windows.
