Database & SQL

Exposes an Oracle database to MCP clients over stdio, offering 75 tools to query, modify, inspect, and triage the database with zero-install thin mode requiring no Oracle Client. Every statement is recorded in a Markdown audit log.

Gives coding assistants a local-first SQLite store for project and global lessons with evidence, immutable replacements, retrieval tracking, and agent feedback, searched by keyword out of the box or by optional local semantic search. It runs over MCP stdio with launch-bound workspace scopes and write permissions disabled by default, so assistants can save, supersede, archive, retrieve, and rate memories entirely on the local machine.

Enables Claude to explore, query, and modify MongoDB databases through natural language, including CRUD operations, aggregation, indexing, and administrative tasks.

Enables agents to fetch public URLs as noise-free Markdown (via Jina Reader with a local HTML fallback) protected by SSRF and indirect prompt-injection defenses, while capturing each article's hook, heading rhythm, and sentence-ending style as a reusable writing recipe in a local DuckDB style vault so that recipe can later drive automated manuscript generation.

## What is Surprise Buddy? Surprise Buddy is a curated, country-scoped gift database exposed via a public Model Context Protocol (MCP) server. International coverage — every result is a real product page on a real marketplace (Amazon, Etsy, Mercado Libre, Otto, Bol.com, Allegro, Jochen Schweizer) and the link can be presented to the user as-is. **Live MCP endpoint:** `https://www.surprise-buddy.com/api/mcp` ## Exposed tools - **`find_gifts`** — main search (country required, all other fi...

Enables agents to manage a local SQLite task backlog over stdio, with tools to create, search, list, get, update, and stat tasks while preserving audit history and idempotency.

Run SQL queries on BigQuery datasets, list tables, and inspect schemas. Manage jobs, export results, and explore data warehouse resources.

Enables agents to validate, explain, and gate SQL statements against a supplied schema before execution, returning safe/review/blocked verdicts, issue codes, and fix suggestions. It acts as a pre-execution go/no-go guard and composes with database access servers.

Enables MCP clients on macOS to read local KakaoTalk chats and messages directly from the app's encrypted database, and to send messages through the app's Accessibility interface with explicit confirmation. It works offline against the installed desktop app without contacting Kakao's servers.

Enables AI agents to read-only query a SQLite database, inspect schema and table summaries, and execute SELECT queries with pagination through MCP.

Enables searching GitHub repositories, fetching readable web page text, and querying a local book database through MCP tool calls.

Enables AI agents to connect to and interact with MySQL, Redis, and MongoDB through a stdio MCP server, with unified data source discovery, read-only querying, and explicitly authorized write operations.

Enables agents to conjure individual sounds by semantic text search over a CLAP-embedded audio database and render them into stereo, 5.1, or 7.1.4 spatial mixes, with tools for summing mixes, analyzing a mix's sounds and spatial balance, and mimicking existing mixes. Documentation resources are exposed so the client can read usage guides on demand.

Enables LLM agents to maintain structured long-term memory and knowledge using SQLite, with graph storage and relational query tools for persistent context.

Enables natural language queries to a local PostgreSQL database for inventory and order information via MCP tools.

Enables LLMs to answer small business finance questions about spending, sales trends, cash flow projections, and profitability using a local SQLite database.

Enables read-only PostgreSQL interaction with enforced SQL security policies, including query validation, row limits, and timeouts.

Enables AI harnesses to maintain a persistent memory layer backed by a local SQLite file, providing MCP tools to add, search, deprecate, and synchronize facts without deleting history.

Enables an AI assistant to diagnose a local WordPress install by listing plugins, checking PHP/WP environment, tailing debug logs, running guarded read-only SQL queries, and inspecting Gravity Forms error and add-on logs.

Enables local coding agents to safely inspect and query PostgreSQL databases — listing schemas, tables, and columns and running capped SELECT statements across multiple configured environments — while the server itself holds the database credential so the LLM never sees it.

Enables agents and Claude Desktop to query a single canonical source for multifamily marketing metrics, with 22 tools for retrieving metric definitions and values from a synthetic portfolio database.

Enables paper and live trading on Polymarket five-minute BTC, ETH, SOL, and XRP Up/Down markets, with order execution, Chainlink TWAP data, SQLite audit history, and optional automatic local stop-losses.

Enables Codex to safely discover and query PostgreSQL connections saved in DBeaver through structured, parameterized read-only SELECTs, including catalog inspection, query analysis/execution, settings retrieval, and sanitized log summaries. It enforces read-only transactions, server-side validation, and bounded access without accepting free-form SQL or exposing credentials.

Enables read-only reconciliation and member/billing queries against a gym SQLite database through typed domain tools, allowing natural-language interaction from Claude.
