Pre-build reality check for AI coding agents. Scans GitHub, HN, npm, PyPI, Product Hunt. MCP server. 290+ stars.

Governance standard and reference toolset for LLM-maintained knowledge corpora

Verified generative visualization for React and agents, with deterministic chart validation, repair, rendering evidence, and MCP.

380+ live data, validation and utility APIs in one MCP server: IP, DNS, email, FX, weather and more.

IBAN, ISIN, VAT/tax ID, GTIN validation; timezone, geo, text, chain utilities. Pay per call

Connects MCP-compatible clients and CI pipelines to a hosted endpoint exposing tools for SaaS revenue-leak audits, ghost-usage evaluation, EU VAT validation, B2B net-terms reconciliation, webhook signature verification and replay simulation, dispute-evidence staging/linting, and ROI calculation.

Enables an AI assistant to deterministically score hands of a Persian trick-taking card game from conversational bids and results, returning updated totals, validation errors, and plain-English explanations.

Lead validation over MCP: KVK/KBO register, EU VAT, sanctions and email checks with sources.

Blitz Strike — a universal MCP security-audit toolbelt. Reconnaissance at speed. Analysis in depth. Validation before report.

DataNexa is a local, read-only database MCP gateway for AI agents. It routes SQLite, MySQL, PostgreSQL, and any JDBC-compatible database through a single localhost endpoint, enforces read-only access via SQL AST validation with row, time, and connection limits, and keeps a local audit trail of every query.

Thea Software is an engineering verification layer for AI agents that binds code changes to explicit validation commands. It bridges conversational models to robust software runtimes, enforcing automated build checks so that code drift and unverified changes are actively rejected.

Enables an AI assistant to inspect a multicolor 3MF project, convert it into checked, printer-specific files for named multicolor printers, and read validation results locally over stdio.

Serves the free Frankfurter exchange-rate API as MCP tools over stateless Streamable HTTP on Cloudflare Workers, letting clients list supported currencies, fetch the latest rates, and look up historical rates for a given date. Each OpenAPI operation becomes one tool, with argument validation and per-IP rate limiting.

Enables coding agents to run taste heuristics on MapLibre style JSON, catching rainbow fills, low-contrast labels, crowded text layers, and light-only palettes via a check tool, plus basic structure validation and locating a local showcase for preview.

Enables clients to retrieve customer records by ID and issue refunds to active customers over stdio, with strict schema validation and JSON-RPC error mapping.

Model Context Protocol server for Markdy diagram validation, transpilation, and generation.

Enables automated validation of corporate travel policies, hotel rate-parity audits, and carbon ESG compliance checks through MCP tools.

Enables read-only access to Percona Monitoring and Management 2.x through PromQL metric queries and Query Analytics, so clients can list monitored databases, surface the slowest queries, inspect query details, and run validated SELECT queries against QAN's ClickHouse data. TLS verification, input validation, and Viewer-role tokens keep access strictly observational.

Enables MCP clients to identify connected drives, read/write and back up parameters, control speed and positioning, capture oscilloscope data, flash firmware, and run validation workflows through existing Drivesoft communication components.

Enables AI clients to create, configure, validate, and generate STM32CubeMX projects through 113 MCP tools, including pin, clock, peripheral, RTOS, and middleware setup plus C code generation. It can drive an installed CubeMX engine or run fully standalone using a bundled data pack with real pin and mode validation.

Enables AI assistants to access curated life sciences CRM migration intelligence for readiness assessment, module mapping, regulatory compliance, integration architecture, multi-country rollout planning, system validation, and troubleshooting.

Process assessments: question packs, multi-respondent sessions, validation and result packages

Email validation for Claude and any MCP client — verdicts with evidence and bulk jobs.
