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
