"A server for finding real research papers" matching MCP connectors:

Conformance checker for MCP servers. Free, no key, verdicts recomputable and re-measured daily.

Generate synthetic random user data for testing, demos, and development without using real persona.

Simulate, test, and analyze cloud architectures without deploying real infrastructure. Cloud World Model enables AI agents to model cloud environments, evaluate architecture behavior and costs, run failure and chaos simulations, and explore infrastructure scenarios across cloud providers.

Drive real Android & iOS devices and web browsers from natural language for mobile + web QA. 145+ tools across device control, app management, automation sessions, browser automation, and flow recording / replay. Bearer-auth — get a token at robotactions.com → Profile → API Tokens.

Prompt evals over MCP: run a prompt on your dataset, score each output 1-5 with an LLM judge.

Evidence-gated task verification for AI agents. Decompose goals into acceptance criteria, attach proof (screenshot, curl, file), independent LLM judge accepts or rejects. 24 tools. Hosted remote MCP (streamable-http, OAuth 2.1 + DCR).

Hosted MCP server to lint SKILL.md files: packaging checks, regex tests, JSON validation, diffs.

Hosted MCP server for structured code review passes on human- and AI-written code. Free tier.

Score any URL against a real design contract — 40 checks, A-F grade, token + motion validation.

A skeptical senior-engineer code reviewer over MCP: risk-scans unified diffs, flags AI-generated-code tells, reports complexity hotspots, scans for leaked secrets, and runs an OWASP security pass — real analyzers, no external APIs. Free tier, no signup.

A fully free linter for agent skill files: lint_skill validates YAML frontmatter, structure, size budgets, and safety phrasing with a pass/fail verdict; packaging_check validates zip layout against marketplace rules; plus regex_test, json_validate, diff_texts, and cron_explain for skill authors. No license or account required.

Scan any website or MCP server for agent readiness: 0-100 score, a fix per failing check. Free.

Security + bug + perf + refactor audit for Python. Returns 0-10 score + MD report.

49 deterministic tools for text integrity, agent control, and contextual quality evidence.

Paid x402 MCP tool for stress-testing launch and marketing copy before publication.

Post-scrape data cleaner, no LLM: repairs mojibake, HTML, invisible chars. Plus a verdict.

Exposes FEDLIN's public security scanners as agent-callable tools over Streamable HTTP.

Benchmark-first release surface with a read-only MCP endpoint and operator CLI.

A webhook inbox for agents: one call returns a live URL. Mock, verify, inspect and replay.

Preflight QA for AI-agent deliverables with structured verdicts and repair guidance.
