Data & Databases MCP Servers

MCP server for interacting with APIs and web services

MCP server for persistent, semantic memory across AI sessions

MCP server exposing Postgres, Redis, Elasticsearch, MySQL, MongoDB, and LDAP as tools, with lazy connection management, retry, circuit breaking, per-connection read-only mode, and optional database drivers.

A Lightweight MCP (Model Context Protocol) client library for JavaScript applications, supporting multiple storage backends and real-time SSE support.

BioMedCP - Biomedical Context Protocol Server for querying knowledge graphs (Neo4j) and electronic health records (SQL)

MCP server for validating, transforming, and normalizing structured data - built specifically for AI agents

MCP server for agent automation: persistent memory and deterministic workflow execution for AI agents and chats

Safety-first, read-only PostgreSQL MCP server. Read-only isn't a regex — it's enforced by Postgres itself (READ ONLY transactions, statement timeouts, row caps). One npx command to give AI agents safe access to your database.

Official Bitcompare MCP server — crypto yield data, prices, coin metadata, stablecoin data, and market stats for Claude and other MCP-compatible agents.

MCP server exposing safe, read-only-by-default PostgreSQL access.

An MCP server plus a CLI tool that indexes local code into a graph database to provide context to AI assistants.

- Model Context Protocol with Neo4j (Run queries, Knowledge Graph Memory, Manaage Neo4j Aura Instances)

One gateway in front of every protocol. Same policy across MCP, LLMs, databases and containers. Wire-level enforcement at under 5ms.

– A high-performance multi-database MCP server built with Golang, supporting MySQL & PostgreSQL (NoSQL coming soon). Includes built-in tools for query execution, transaction management, schema exploration, query building, and performance analysis, with seamless Cursor integration for enhanced database workflows.

Demo of a customer service agent (Cymbal Air) using LangGraph, Tools, and RAG to interact with Google Cloud Databases via MCP Toolbox.

An agentic memory database that cuts session tokens by 82–99%. One portable SQLite file — your agent's memory, anywhere.

Zero-config entity resolution. The zero-tuning Fellegi-Sunter path beats hand-rolled Splink head-to-head; scales from a CSV to a verified 100M-row dedupe in 9.2 min on Ray. Fuzzy/exact/probabilistic + PPRL + LLM, identity graph. Python + edge-safe TypeScript (optional WASM), SQL-native in Postgres & DuckDB, MCP/REST + dbt/Airflow.

Store, query, and update structured data from any AI agent

Enables natural language schema queries — explore tables, keys, procedures, and get SQL help fast

Local-only Tableau .twbx audit: lineage, unused fields, duplicate calcs, SQL, version diffs

PostgreSQL MCP Server with built-in SSH tunneling for secure database access through bastion hosts

Engine-free, governed Oracle Database MCP server with a fail-closed SQL guard (unofficial).

Persistent memory for AI coding agents: one Rust binary, one local SQLite database.
