How these are rankedShowHide
Rule. Every listing in Self Protocol’s own category (Security Tool) that carries a Sato Score, ordered by score tier, observed liveness, deploy-spec and reproduced-install evidence, and chain overlap with Self Protocol.
This page ranks peers on how open, active and verifiable each one is — the same evidence Sato Hub publishes everywhere else. It is not a quality, safety or performance ranking, it declares no winner, and it cannot tell you which of these fits your codebase. A Sato Score is not an audit: none of these has been security-reviewed by Sato Hub, and a listing with no earned verification is self-reported.
| # | Alternative | Sato Score | Liveness | Chains | Differs on |
|---|---|---|---|---|---|
| 1 | MistTrack MCP✓ reproduced MCP server from SlowMist exposing MistTrack address risk scoring and fund-flow tracing to AI agents. npx -y misttrack@latest --key YOUR_MISTTRACK_API_KEY install reproduced by Sato Hub | High | Quiet · 6mo ago | Ethereum, Bitcoin, Polygon, Solana, Multichain | Typed as tool/service rather than infrastructure; also on Ethereum, Bitcoin, Polygon, Solana; deploys as npx, npm global install, local development. |
| 2 | GoPlus AgentGuard✓ reproduced MIT-licensed runtime guard for AI coding agents: hook-level action blocking, a 24-rule skill scanner, and a per-skill trust registry. npm install -g @goplus/agentguard install reproduced by Sato Hub | High | Active · 9d ago | — | Typed as tool/service rather than infrastructure; does not list Multichain. |
| 3 | Agent Skills Hub✓ reproduced A registry of AI agent skills that applies automated source-code scanning and assigns security grades before installation. npx agent-skills-hub install reproduced by Sato Hub | High | Active · 26d ago | — | Does not list Multichain; partly open source; deploys as npx. |
| 4 | PulseFeed✓ probed PulseFeed checks an x402 endpoint before an agent pays it (liveness, a 0-100 score, receiver and price flags) and tracks changes to MCP servers and npm packages. Ships a guard SDK, an MCP server, and Vercel AI SDK and LangChain tools. no deploy spec on record | High | Active · 7d ago | Base | Also on Base; does not list Multichain; deploys as hosted, self-hosted, npm package. |
| 5 | Socket✓ probed Dependency and package analysis from Socket, with a CLI and an MCP server that returns package scores to an AI assistant. no deploy spec on record | High | Active · today | — | Typed as tool/service rather than infrastructure; does not list Multichain; partly open source; deploys as npm, mcp server, hosted. |
| 6 | Intercepts agent transactions and checks them against 5 security oracles before execution. pip install cryptoguard-ai install as documented by the project — not reproduced | Medium | Active · 4d ago | Multichain | Typed as tool/service rather than infrastructure; deploys as CLI tool, Python library, MCP server. |
| 7 | Keyless REST APIs for token risk, approval risk, malicious addresses, signature decoding and transaction simulation across 46 chains. no deploy spec on record | Medium | no signal | Multichain | Typed as tool/service rather than infrastructure; partly open source. |
| 8 | PRXVT✓ reproduced Open-source privacy SDK that adds unlinkable, zero-knowledge payments on top of the x402 agent payment standard. npm install @prxvt/sdk install reproduced by Sato Hub | Medium | no signal | Ethereum, Base, Polygon | Also on Ethereum, Base, Polygon; does not list Multichain; deploys as npm. |
| 9 | Usenami Signer MCP✓ reproduced MCP server that signs CEX/DEX orders inside an attested AWS Nitro Enclave so keys never touch the agent process. npm install @usenami/signer-mcp install reproduced by Sato Hub | Medium | Active · 27d ago | — | Does not list Multichain. |
| 10 | Agent-identity authentication protocol modeled on Sign-In-With-Ethereum, letting services verify an agent before granting access. npm install @buildersgarden/siwa install as documented by the project — not reproduced | Medium | Quiet · 6mo ago | Ethereum | Typed as standard rather than infrastructure; also on Ethereum; does not list Multichain. |
“Differs on” is derived from the records — type, chains, openness and deployment — and states a difference, never a preference. ✓ marks an earned state named as what was checked; none of them is a safety claim.

Questions about alternatives to Self Protocol
- What are the alternatives to Self Protocol?
- MistTrack MCP, GoPlus AgentGuard, Agent Skills Hub, PulseFeed, Socket, CryptoGuard, GoPlus Security, PRXVT, Usenami Signer MCP, SIWA (Sign In With Agent) are listed in the same category as Self Protocol (Security Tool), as of 2026-10-28. The order is Sato Score and observed evidence, not a quality judgment.
- Which alternatives to Self Protocol are open source?
- 7 of 10: MistTrack MCP, GoPlus AgentGuard, PulseFeed, CryptoGuard, PRXVT, Usenami Signer MCP, SIWA (Sign In With Agent). Openness is read from each project's own published license or repository.
- Which alternatives run on the same chains as Self Protocol?
- 3: MistTrack MCP, CryptoGuard, GoPlus Security. Chain support is self-declared by each project unless a named check says otherwise on its listing.
- Has Sato Hub verified any of these?
- Sato Hub reproduced the documented install for 5 of them: MistTrack MCP, GoPlus AgentGuard, Agent Skills Hub, PRXVT, Usenami Signer MCP. Reproducing an install means the documented setup was actually run — it is not a security review, and Sato Hub holds no security assessment of any of these.
- How is this list of alternatives built?
- It is a rule over live records, not a hand-written list: every listing in Self Protocol's own category that carries a Sato Score, ordered by the same evidence the rest of the site ranks on — Sato Score tier, whether an endpoint answered our probe, whether a deploy spec exists and was reproduced, a sustained observed record, and chain overlap with Self Protocol. It is rebuilt from the records, so it changes when they do.
