CTRLRun Approval Consoleofficial
AlicenseAqualityAmaintenanceAnswer CTRLRun approvals from your assistant: list the agent actions waiting on a human, inspect one action's full history, and approve, deny or resolve it, plus read receipts, effects and stats. Reads answer without a credential; the three write tools refuse without one that names a person.4825Apache 2.0- AlicenseAqualityDmaintenanceFree certification prep for the Claude Certified Architect exam. 390 scenario-based questions, guided capstone build, 30 concept handouts, 6 reference projects, practice exams, interactive UI with clickable answer cards, progress dashboard, spaced repetition, and deterministic grading.

fetchsandbox-mcpofficial
AlicenseAqualityAmaintenanceA deterministic eval engine for coding agents. Your agent claims it fixed the bug—this checks it. The same scenario runs twice against a sandbox of the services your code calls, with failures injected on purpose. It must fail on the old code and pass on the new. The verdict is an exit code, not a model's opinion. Every run leaves a receipt.816433 npm1MIT- AlicenseAqualityAmaintenanceAddress Markdown and GEML documents by block instead of by line: list, get, set, add, delete, rename, revert, find and check one block, with every write re-parsed and refused if it would brea751128MIT
- AlicenseAqualityAmaintenanceChecks whether an open-weight LLM fits your GPU: VRAM for weights, KV cache and overhead at each quantisation, a tokens-per-second ceiling, the longest context that fits, and what would work instead when it doesn't. Reads any Hugging Face repo's config.json. Free, read-only, no API key.46MIT

MCP ConnectorsBrowse all →
Check an A2A agent before you delegate, or an MCP server's measured conduct. Free, no key.
formcarry handles everything after your form is submitted: it emails you, auto replies to the person who submitted, filters spam, and delivers webhooks. You write the HTML form and set its action to a URL formcarry gives you. An agent can create a form, wire the emails and webhooks, and answer questions about the submissions, like how many signups last week.
Crawl and scrape websites to clean markdown, and track what changed between crawls.
Contract-change authorization for AI agents: preflight a change to an API or MCP contract, get a signed decision, and verify the receipt offline. Only a granted change can proceed.
Open AI models through one OpenAI-compatible API: chat, live model list, prices and cost estimates.
Tailwind CSS palettes (50-950) from any color, the closest Tailwind color, and Tailwind's defaults
Go MCP server for GitLab: 2 dynamic tools reach 1000+ REST/GraphQL actions. Free/CE, no paid tier.
Traffic Parrot simulates APIs and messaging. Request or withdraw a trial, read docs, send feedback.
Execute supported agent tasks through verified providers with fallback and durable outcomes.
Connect Claude, ChatGPT, Cursor or any MCP client to Ybug. Read bug reports with screenshots, console logs and network requests, then triage them in chat.
Deterministic SHA, HMAC, Base64 and JWT decode tools with prepaid direct-USDC API credits on Base.
AI agents run business processes on your business data. Every change is attributed and reversible.
Run a GPU job under a hard dollar cap and collect the files it writes.
