Yaci Store 3.0 Beta Add SQL Analytics and MCP Access to Cardano Data
By SongMarketCap
BloxBean test release don expand how developers fit query Cardano blockchain data and connect am to AI tools. Another stable release wey separate improve token metadata support and governance records.
BloxBean release Yaci Store 3.0.0-beta4 on September 23. Yaci Store na Cardano blockchain indexer wey arrange chain data make applications fit use am. The beta add SQL analytics, one optional MCP server and more Blockfrost-compatible APIs. Stable version 2.0.3, wey dem publish the same day, bring data fixes for existing installations.
More Cardano Data Through Developer APIs
Cardano applications need indexed data to show transactions, assets, stake pools and governance activity. Yaci Store allow development teams run that data layer by themselves and provide am to their applications through APIs.
The 3.0 beta add Blockfrost-compatible endpoints for network information, stake pools, governance actions and DReps. For team wey already dey use that API format, the additions provide more Cardano data wey dem fit test against their own Yaci Store installation. The release notes talk say coverage don expand, no be say e compatible with every Blockfrost endpoint, so application required endpoints still need make dem check am one by one.
Developers fit also write Java plugins for custom indexing. This one let team adapt how Yaci Store dey process data for specific product without to change the Cardano blockchain or build indexer from scratch.

SQL Analytics and MCP Access
The new analytics-query module dey run SQL queries over indexed data wey dem export for Parquet format, using DuckDB. Team fit use those queries to examine the history wey their indexer collect, side by side with the API requests wey their application dey make during normal operation.
Optional MCP server expose analytics and utility functions to connected AI tools. The functions include discovery of available tables, running SQL queries, retrieving address balances and converting between Cardano slots and time. SQL access dey limited to read queries, with controls on result size and execution time. Operators must enable the MCP server explicitly.
That combination give developers clear way to investigate their own Cardano datasets: inspect which records dey available, query dem and pass the results to connected tool. Na access to data wey Yaci Store hold, no be new AI capability of the Cardano protocol.
Stable 2.0.3 Improve Token and Governance Records
Version 2.0.3 add CIP-26 metadata support and CIP-68 metadata support for fungible tokens. The 3.0 beta extend CIP-68 coverage to non-fungible tokens. Accurate indexed metadata matter for applications wey dey identify and display Cardano assets.
The stable release also correct several governance records, including stale votes after DRep deregistration, selection of the latest SPO and constitutional committee votes, and stake calculations wey dem use for SPO voting. Governance dashboard dey depend on those records to present the current voting picture. The fixes change wetin Yaci Store dey calculate and return; dem no change Cardano voting rules.
Installations wey dey run 2.0.2 fit apply the stable release database migration at startup, although to enable CIP-68 indexing go require full resync. For 3.0.0-beta4, BloxBean recommend fresh database and sync from genesis. That recommendation cover the same ledger, governance and metadata history wey developers go examine through the beta new SQL and MCP tools.
