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

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

FAQ

What can an MCP-connected agent actually do with Indexing Co data?

Agents can query indexed events, inspect schemas, monitor pipeline status, and manage pipeline configurations through tool calls instead of custom integrations.

Do agents need to know SQL or blockchain RPC details first?

No. MCP exposes typed tools and structured responses, so the agent works through the protocol layer rather than raw RPC payloads or bespoke API clients.

Can I combine Indexing Co MCP tools with other agent tools?

Yes. MCP is composable, so blockchain data access can sit alongside file, database, planning, or execution tools in the same workflow.
