"address validation" matching MCP servers:

IBAN validation across 89 countries, BIC/SWIFT and Swiss clearing lookup, batch validation, payment-reference, postal-address and Swiss QR-bill checks for AI agents. Connect via MCP or the REST API. Includes free quotas, paid credits and a Pro subscription. SEPA and country-risk indicators support payment-data checks; they do not confirm account ownership or replace beneficiary AML/KYC screening.

Official SQAI MCP server: governed structured data access powered by Mojo kernels. 3 stdio tools: listSources (discovery), queryData (deterministic read-only queries + compute with provenance), explainQuery (dry-run validation). Introspection needs no credentials; execution requires a one-time free sqai login. npm: @thyn-ai/sqai-mcp. Source: packages/mcp. Registry: io.github.thyn-ai/sqai.

Lets users manage master data through natural-language conversations with AI agents, enabling schema creation, record capture, validation, search, and query answering via 16 MCP tools backed by local JSON storage.

A drop-in Model Context Protocol (MCP) server that lets an AI agent query PostgreSQL — read-only, enforced at the database level, with real SQL validation, timeouts, cost limits, OAuth 2.1, and an audit trail.

Enables read-only interaction with PostgreSQL databases through natural language queries, supporting dynamic connections and secure query validation.

Radar-verified storm intelligence for the continental US — NOAA MRMS hail and wind swaths, per-address storm history, affected-property reports, area monitors with webhook + email alerts, and swath map images. Boots keyless; free API key (100 credits) at swathapi.com.

Enables AI agents to explore licensed IP intelligence databases through four read-only tools: listing the databases an organization is licensed for, inspecting a database's columns, sample rows, row count and build date, fetching published checksums for verifying a local copy, and reviewing recent download attempts. It covers VPN, proxy, hosting, CDN and relay address space data without transferring the multi-gigabyte files themselves.

MCP server exposing SPARQL query functionalities for LLMs, enabling query execution, validation, and graph exploration across SPARQL endpoints.

SQL Server MCP server with AST-based query validation, read-only safety, schema exploration, ER diagram generation, and DBA toolkit integration (First Responder Kit, DarlingData, sp_WhoIsActive).

This MCP server enables database migration between heterogeneous systems (Oracle, PostgreSQL, SQL Server, Netezza to PostgreSQL or SQL Server) through AI assistants by providing tools for command preview, execution, validation, and workflow suggestions.

Enables read-only exploration and querying of PostgreSQL or MySQL databases via MCP, with schema discovery, safe SQL validation, natural language to SQL conversion, and CSV export.

Provides access to 1,709 Icelandic statutes and 19,026 provisions with full-text search, citation validation, and EU/EEA law integration, enabling legal research and compliance checks through natural language queries.

Provides read-only MySQL query execution, database/table browsing, and table structure inspection with SQL safety validation.

Enables grounded bilingual English/Tagalog question answering over the Metro Manila flood-exposure atlas by generating read-only SQL and searching public-safety briefs, with validation that every numeric claim is grounded in tool output.

Enables secure task CRUD operations on SQLite or MySQL databases with input validation, parameterized queries, audit events, transactions, and signed delete confirmation.

An AI-to-DB secure gateway that enables AI assistants like Claude Code to interact with MySQL databases through controlled, auditable operations with permission modes and AST-level validation.

Enables an AI client to search Australian federal and South Australian government open data catalogues, inspect a dataset file's schema and sample rows, then run read-only SQL over the full file in a sandboxed DuckDB. Every answer carries the source URL, publisher and licence, with extra tools for ABN checksum validation and Australian financial-year dates.

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

Read-only JDBC MCP server for PostgreSQL, Oracle, and SQL Server: safe SQL access for AI agents (Claude Code, Cursor, Copilot) with schema discovery, query validation, execution plans, benchmarking, and index/statistics tools

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.
