MCP

Connect to the hosted Fusion MCP server: tools, resources, prompts and a worked example for inspecting vaults.

MCP

Model Context Protocol server for IPOR Fusion. Use it to inspect deployed vaults, resolve addresses and research markets from any MCP-capable client (Claude, Cursor, custom agents). This server is read-only inspection and research — it does not create or configure vaults. For that, use the Python SDK (see also Deploy your first Fusion vault).

Connect

Transport: Streamable HTTP Server URL: https://mcp.ipor.io/mcp

Add it through the MCP settings of your client — do not open the URL as a normal webpage.

Quick add (Claude Code):

claude mcp add --transport http ipor-fusion https://mcp.ipor.io/mcp

Manual mcpServers config (Claude Desktop, Cursor, and similar clients):

{
  "mcpServers": {
    "ipor-fusion": {
      "url": "https://mcp.ipor.io/mcp"
    }
  }
}

For a locally installed alternative, the same server ships bundled with the Python SDK: Install the SDK-bundled Fusion MCP server.

Tools

Tool	What it does
vault_info(vault_address, chain_id, block_number=0)	Full on-chain state of a Plasma Vault: asset, TVL, supply cap, fees, managers, fuses, balance fuses, substrates, alpha config, health check.
vault_oracle_mapping(vault_address, chain_id, block_number=0)	Resolves how a vault prices every configured asset, recursing through composed and derived price feeds (Chainlink, ERC4626 share price, Morpho collateral, middleware fallback).
vaults_list()	All IPOR Fusion vaults from the public API: chain, address, name, asset, APY, TVL.
fusion_addresses_list(chain_id)	The full {contract name: address} map for one chain, sourced from ipor-abi.
fusion_address_names(chain_id=0)	Discover which contract names exist, across all chains or for one chain.
fusion_address_lookup(query, chain_id=0)	Resolve a contract by name (substring) or by address, across all Fusion deployments.
market_morpho_blue(market_id, chain_id, block_number=0, no_api=false)	Inspect a Morpho Blue market: params, on-chain state, borrow/supply APY, supplying MetaMorpho vaults.
market_meta_morpho(vault_address, chain_id)	Inspect a MetaMorpho V1 or Morpho Vault V2: roles, fees, allocations/adapters, per-market caps and headroom.

Resources (fusion://)

Resource	Contents
fusion://glossary	Canonical terms — Atomist, Alpha, Fuse, Plasma Vault, and the rest of the vocabulary used across these docs.
fusion://architecture	How the pieces of a Fusion vault fit together.
fusion://invariants	Common revert selectors and the role table an agent should know before sending a transaction.
fusion://quickstart	The executed vault-deploy walk (also mirrored in the SDK and the Deploy your first Fusion vault page).

Prompts

Prompt	Use it to
quickstart	Orient a fresh agent to Fusion.
deploy_vault	Walk through creating and configuring a vault.
analyze_vault	Inspect an existing vault's configuration and health.
trace_oracle_pricing	Follow a vault's price-feed chain end to end.
explain_fuse	Explain what a specific Fuse does.

Worked example: inspect a vault

# 1. Get the vault's full on-chain state
vault_info(
    vault_address="0x...",
    chain_id=8453,  # Base
)
# -> asset, total_assets, total_supply, fees, fuses, balance_fuses, substrates, alpha config

# 2. Understand how it prices its assets
vault_oracle_mapping(
    vault_address="0x...",
    chain_id=8453,
)
# -> per-asset price source, feed type, and the resolved price for each configured asset

Combine the two to answer "what is this vault holding, and can I trust its price feeds?" without reading a single line of source.

Rules for agents

• This server is for deployed-state inspection and research only.

• Use the Python SDK for vault creation and transaction construction.

• Resolve production addresses through fusion_address_lookup / fusion_addresses_list, not by guessing or copying from tests.

• An address returned here does not, by itself, prove a Fuse or component is compatible with a particular vault, market or strategy.
