DataScript MCP Server
DataScript MCP server enabling AI agents to use DataScript — the immutable in-memory database with Datalog query language inspired by Datomic — querying structured data with Datalog, managing entity-attribute-value data models, and integrating graph-capable in-memory data storage into agent-driven data analysis workflows.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Local in-memory only. No network. No persistence. No credentials needed.
⚡ Reliability
Best When
An agent needs flexible Datalog queries over structured in-memory data — particularly for graph-like queries or knowledge representation use cases.
Avoid When
You need persistent storage, SQL familiarity, or large-scale data — use SQLite, PostgreSQL, or Neo4j MCPs instead.
Use Cases
- • Querying complex relational data with Datalog from analysis agents
- • Maintaining in-memory knowledge graphs from reasoning agents
- • Storing and querying entity-attribute-value data from data modeling agents
- • Exploring Datomic-style immutable data patterns from architecture agents
- • Graph traversal queries on structured data from knowledge agents
- • Building agent memory systems with temporal data semantics
Not For
- • Persistent data storage (DataScript is in-memory only — no persistence)
- • Teams unfamiliar with Datalog query language
- • Large datasets (in-memory only — limited by available RAM)
Interface
Authentication
No authentication — in-memory local database. Data exists only for the duration of the MCP server process.
Pricing
Free open source. DataScript library is free (Eclipse Public License).
Agent Metadata
Known Gotchas
- ⚠ Datalog query syntax is unfamiliar to most LLMs — requires careful prompting
- ⚠ In-memory only — all data is lost when MCP server restarts
- ⚠ Data must be loaded fresh on each session — no persistence between restarts
- ⚠ Community MCP — niche use case with limited community support
- ⚠ ClojureScript/JavaScript runtime required for DataScript execution
- ⚠ No SQL interface — LLMs may struggle to generate correct Datalog syntax
