MCP Blockchain Data Access

Give AI agents direct, tool-based access to indexed blockchain data via Model Context Protocol. Query events, balances, and pipelines from any MCP-compatible agent.

AI agents are only as useful as the data they can access. When an agent needs to check a wallet balance, query recent swap events, or monitor a smart contract, it shouldn't need custom API integrations or database connections. It should call a tool and get structured data back.

Indexing Co's MCP server gives any MCP-compatible agent -- Claude, Cursor, or custom frameworks -- direct access to indexed blockchain data across 100+ chains through standard tool calls.

How It Works

1. Connect: Add the Indexing Co MCP server to your agent's configuration. One connection, all data.

2. Query: Agents call tools like get_events, query, and describe_data to access indexed blockchain data. No SQL, no GraphQL -- just structured tool calls with structured responses.

3. Act: Agents use the returned data to make decisions, trigger actions, or feed downstream workflows. Real-time data means real-time agent capabilities.

What Agents Can Do

Query Indexed Events

Retrieve decoded blockchain events by chain, contract, event signature, or time range. Get structured data ready for agent reasoning -- not raw hex that needs parsing.

Monitor Pipeline Status

Check pipeline health, event counts, and processing latency. Agents can self-monitor their data sources and alert on issues.

Create & Manage Pipelines

Advanced agents can create new indexing pipelines, add filters, and configure transformations -- programmatic infrastructure management through tool calls.

Describe Data Schemas

Agents can discover what data is available by calling describe_data to see field names, types, and sample values. Self-documenting data access.

Why MCP for Blockchain Data

• Zero integration overhead: No API keys to manage, no SDKs to install, no endpoints to memorize -- MCP handles the protocol
• Agent-native interface: Tools with typed parameters and structured responses -- the way agents are designed to interact with systems
• Composable: Combine blockchain data tools with other MCP servers (databases, APIs, file systems) in the same agent
• Framework-agnostic: Works with Claude Desktop, Cursor, custom agent frameworks, and any MCP-compatible client
