Canister IDs

This page provides the official mainnet canister IDs for the core services of the Prometheus Protocol. Use these principals when interacting with the protocol directly or configuring your services and clients.

Core Protocol Services

These are the primary backend canisters that orchestrate the protocol’s logic.

Service Name	Description	Canister ID (Principal)
MCP Registry	The central on-chain registry for applications, WASM versions, and verification status (ICRC-118/126).	`grhdx-gqaaa-aaaai-q32va-cai`
MCP Orchestrator	The secure deployer that manages canister deployments, ensuring only verified WASM is used (ICRC-120).	`ez54s-uqaaa-aaaai-q32za-cai`
Auth Server	The on-chain OAuth 2.1 provider for user and agent authentication.	`bfggx-7yaaa-aaaai-q32gq-cai`
Audit Hub	The backend service for the bounty and attestation system (ICRC-127).	`eq6xo-cyaaa-aaaai-q32yq-cai`
Usage Tracker	The “Beacon” service that collects Proof of Usage metrics for the rewards program.	`m63pw-fqaaa-aaaai-q33pa-cai`
Example MCP Server	A reference implementation of a basic MCP server deployed on the mainnet.	`jcavt-oyaaa-aaaai-q33qq-cai`

User-Facing Frontends

These are the web application canisters that provide user interfaces for the protocol.

Service Name	Description	Canister ID (Principal)
App Store UI	The primary user interface for browsing and discovering verified services.	`jfbth-daaaa-aaaai-q33qa-cai`
Auth UI	The frontend for the login, consent, and token allowance management dashboard.	`bmfnl-jqaaa-aaaai-q32ha-cai`

Token Ledgers

These are the ICRC-1 compliant ledger canisters for the protocol’s tokens.

Service Name	Description	Canister ID (Principal)
PMP Token Ledger	The test Prometheus Protocol (PMP) token ledger for testing paid MCP servers.	`dy3i7-mqaaa-aaaai-q32ja-cai`
preMCPT Ledger	The ledger for the pre-launch `preMCPT` reward token.	`mz2jc-iiaaa-aaaai-q33pq-cai`
