Chainlink Oracle Skill

The most complete Chainlink MCP server available. 20 tools covering the full Chainlink product surface: CCIP v1.6+ cross-chain messaging with token pools and allowOutOfOrderExecution=true, on-chain Data Feeds via AggregatorV3, sub-second Data Streams, VRF v2.5 verifiable randomness, Proof of Reserve verification, Automation upkeeps, and Functions subscriptions.

MCP Endpoint

Service	URL	Description
Chainlink MCP	https://chainlink-mcp.tenzro.network/mcp	Chainlink MCP Server (port 3007)

For local development, use http://localhost:3007/mcp.

Key Concepts

• CCIP — Cross-Chain Interoperability Protocol for secure messaging and token transfers
• Router — Per-chain CCIP entry point contract
• Chain Selector — uint64 identifier for each chain in CCIP
• Token Pool — CCIP v1.6+ Lock/Release or Burn/Mint pool for cross-chain tokens (CCT)
• Data Feeds — On-chain price oracles via AggregatorV3Interface (~1 min updates)
• Data Streams — Off-chain sub-second latency market data (crypto, forex, equities, commodities)
• VRF v2.5 — Verifiable Random Function for provably fair onchain randomness
• Proof of Reserve — On-chain reserve verification for wrapped/synthetic assets
• Automation — Decentralized keeper network for contract maintenance
• Functions — DON-hosted serverless compute for off-chain data

Common Workflows

Cross-Chain Token Transfer

1. ccip_get_supported_chains() — List supported chains
2. ccip_get_lanes(source="ethereum", dest="base") — Check lane exists
3. ccip_get_fee(src="ethereum", dst="base", receiver="0x...") — Estimate fee
4. ccip_send_message(...) — Build transfer tx
5. ccip_track_message(message_id="0x...") — Track delivery

Get Multi-Asset Prices

1. chainlink_get_price(feed_address="0x5f4eC3Df9cbd43714FE2740f5E3616155c5b8419") — ETH/USD
2. chainlink_get_price(feed_address="0xF4030086522a5bEEa4988F8cA5B36dbC97BeE88c") — BTC/USD

Verify Asset Reserves

1. por_list_feeds() — List available PoR feeds
2. por_get_reserve(feed_address="0xa81FE04086865e63E12dD3776978E49DEEa2ea4e") — WBTC reserve

Request Verifiable Randomness

1. vrf_get_subscription(subscription_id="123") — Check balance
2. vrf_request_random(subscription_id="123", key_hash="0x...", num_words=2) — Build request tx
