prometheus-protocol
Prometheus Protocol monorepo for a vertically integrated “trust stack” on the Internet Computer: an identity/Passport layer (described as an OAuth 2.1 provider and MCP-related components), an on-chain payments/bank account layer, and a trusted marketplace/app-store layer (service registry, auditor hub, and related components). It includes deployment instructions for DFINITY canisters and references multiple MCP servers (e.g., token watchlist, wallets, DEXs).
Score Breakdown
⚙ Agent Friendliness
🔒 Security
The README claims an OAuth 2.1 provider and mentions authenticated verifier bots, but provided content contains no specifics on TLS enforcement, token handling, scope granularity, secret management practices, audit approach, threat modeling, or dependency/SBOM/CVE hygiene. Security posture is therefore scored conservatively based on lack of observable details.
⚡ Reliability
Best When
You want to deploy and compose Internet Computer canisters for agent identity, payments/DeFi primitives, and marketplace-style service discovery, and you can handle blockchain/IC operational complexity.
Avoid When
You need turnkey, stable APIs with strong operational guarantees, or you cannot operate/verify smart-contract/canister systems.
Use Cases
- • Providing an on-chain identity/authorization layer for agentic applications (Passport)
- • Enabling agent-operated payments and DeFi interactions via canister-based primitives (Bank Account)
- • Discovering and verifying third-party services through an on-chain marketplace/supply chain
- • Integrating DeFi/oracle tools into an agent workflow via MCP servers
Not For
- • Production use without reviewing current API stability and security posture (explicitly states active development)
- • Teams needing a simple, hosted REST/GraphQL SaaS interface (this is canister/IC tooling-heavy)
- • Use cases requiring mature, well-specified public HTTP APIs with an OpenAPI spec (not evidenced in provided content)
Interface
Authentication
Authentication mechanisms are described at a high level (OAuth 2.1 provider; verifier bots using API keys). No concrete scope model or auth flow details are included in the provided README excerpt.
Pricing
No pricing/tiers for the software itself are described.
Agent Metadata
Known Gotchas
- ⚠ Repo explicitly indicates active development and possible API changes before v1 release
- ⚠ Operational complexity: requires DFINITY/IC canister deployment and local/prod configuration (dfx, cycles, config:inject/check)
- ⚠ No clear details provided (in excerpt) on MCP tool schemas, error formats, retry/idempotency behavior, or rate limit headers
