"The most widely used models" matching MCP servers:

Crash-test AI agents on real professional decisions. Agents take real tariff classification and patent examination cases, search reference libraries and rulebooks, submit a decision, and get an exact score with a receipt against what the professional actually decided. Most cases were decided after current models were trained.

Browser control for Claude Code, on Firefox.

Lets an MCP client query SQLite databases through validated, forced read-only, row-capped, time-limited and logged operations, so AI agents can explore data without risking writes or runaway queries. It also ships an eval harness that measures how accurately a model answers benchmark questions via text-to-SQL through the server.

Runtime access for AI coding agents to observe and control Android and iOS apps.

Enables agents and security automation to adjudicate proposed defense mutations against a sealed, canonicalized attack scenario, enforcing reproduction, impact-screening, regression, and proven-improvement gates before promoting at most one candidate. Every verdict, rejected candidate, and rejection reason is sealed into a recomputable SHA-256 Merkle evidence root and hash-linked lineage that can be independently verified without trusting the server.

MCP server for IFC geometric audit, providing tools to detect space clashes, extract space inventories, compute surface losses, check boundaries, and verify opening correspondences in BIM models.

The most comprehensive ServiceNow MCP server. 17 tools for full CRUD, CMDB graph traversal, background scripts, ATF testing, and more.

Enables users to benchmark AI models across English, Urdu, and Roman Urdu by running question sets, grading answers, measuring confidently wrong and hedged responses, and producing reports, comparisons, and CSV exports through an MCP client or CLI.

Enables remote control of LeCroy oscilloscopes via SCPI commands over LAN to perform waveform capture, screenshots, measurements, channel configuration, and triggering through natural language. Supports multiple LeCroy models including WaveSurfer, HDO, WaveRunner, and WavePro series with automatic model detection.

QA Sphere MCP server that enables Large Language Models to interact directly with test management system test cases, supporting AI-powered development workflows and test case discovery.

Exposes Okareo's evaluation capabilities as MCP tools, enabling AI coding assistants to manage scenarios, register models, run evaluations, and execute multi-turn simulations directly from the editor.

A local MCP server that packages LLM evaluation gates as reusable CI/CD primitives, enabling AI agents to run datasets against models, score responses, and enforce quality thresholds.

Enables natural-language validation of IFC models against Türkiye's building-permit BIM regulation, including compliance checks, EK-9 form generation, and queries about required classes and properties.

Lets assistants send the same test prompts to as many as four text models across OpenRouter, Amazon Bedrock, Google Vertex AI and Microsoft Foundry, then automatically grade each answer with a judge model, rule checks and a policy gate. Returns scored leaderboards with letter grades, per-response strengths and weaknesses, latency, throughput and estimated cost, plus downloadable PDF and CSV reports.

Enables AI agents and MCP clients to perform 3D asset creation and verification: exact b-rep CAD, GLB validation with embedded certificates, mesh inspection, and physics scenes, with most tools running without Blender.

Generates intelligent Playwright locators with reliability rankings, creates Page Object Models, and runs test automation scripts directly from your IDE or AI assistant.

Enables blind AI coding models to debug visual bugs by capturing screenshots, analyzing them with a vision-capable model, and returning a written report.

Enables AI assistants to scan project dependencies and Infrastructure as Code files for security vulnerabilities and misconfigurations. It also provides automated fixing capabilities to remediate identified security issues.

Enables LLMs to automate web browsers using Playwright through structured accessibility snapshots, allowing interaction with web pages without needing vision models.

A Model Context Protocol server that enables generating and managing Robot Framework test automation with SeleniumLibrary, including test case generation, page object models, and advanced web testing capabilities.
