MCP ConnectorsBrowse all →
Shared project memory for AI coding agents: decisions, lessons, risks and tasks in one graph.
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.

Live MCP tools: get_bot_status (Telegram bot health), get_market_stats (market snapshot), get_onchain_sales (proven revenue from live x402 routes). Built for agents that need verifiable onchain data — whale flow, signals, and sales evidence at $0.003/call.
Open AI models through one OpenAI-compatible API: chat, live model list, prices and cost estimates.
Design quality gate for AI-generated UI: score any URL on 45 deterministic checks, A–F grade.
Go MCP server for GitLab: 2 dynamic tools reach 1000+ REST/GraphQL actions. Free/CE, no paid tier.
Crawl and scrape websites to clean markdown, and track what changed between crawls.

Enhanciar is a company brain for engineering teams. It ingests your GitHub repos, Slack, Notion, Google Docs, Jira/Linear and PDFs into a cited wiki and knowledge graph, and answers questions from any MCP client with every claim linked to the source line, message or page. Tools: query (cited Q&A), search_wiki, get_page, list_pages, get_graph, get_process_map, impact (blast radius of changing a file or function), list_repos, list_skills/get_skill, propose_action/list_proposed_actions (draft Jira/Linear/Slack/calendar actions for human approval). BYOK — bring your own model key. Early access: join the waitlist at https://enhanciar.in and create an API key in Settings.
12 free MCP tools for local validation of emails, URLs, IP addresses, IBANs, dates, UUIDs, JSON and other structured inputs. No API key or external verification service required.
Publishes what an AI made — a page, a markdown or PDF doc, or a whole site — to a live HTTPS link. Runs locally over stdio from the @drop2run/mcp npm package, or hosted at https://mcp.dropto.run/mcp for chats that connect by URL.
Email infrastructure for AI agents. Connect your coding agent and it sets up email in your app: create templates, segments, workflows and webhooks, send test emails and read back what was delivered, track events, and create agent inboxes. Sign in with OAuth or use a Volanea API key. Test keys render and log but never deliver. 1,000 emails free every month.
Writes your daily standup from GitLab or GitHub merge request state: what's ready, blocked or waiting on your review, and why a pipeline is red, read from the failing job log. OAuth sign-in, no API keys; can post the note to Slack, Discord or Google Chat on a schedule.
Source-linked evidence and reusable local checks for agent integration and review. Explore seven free evidence packs and three executable products, with questions, demonstrations and direct preview/purchase links: https://varexis.tech/index-packs Agent Tool Admission & Permission Control — GBP 49 + applicable VAT, one time. Supply local JSON declarations for GitHub, Playwright, Notion or Slack. The Node.js24 executable compares actions, resources, recipients, authority and inventory changes, returning a structured gap report. Free demonstration: https://varexis.tech/varexis-index/examples/agent-tool-admission/DEMONSTRATION.txt Agent Audit & Evidence Coverage — GBP 79 + applicable VAT, one time. Supply a declared event/evidence inventory. The local executable checks identity/authorization/action/outcome references and missing capture, export, retention or recovery coverage. Free demonstration: https://varexis.tech/varexis-index/examples/agent-audit-coverage/DEMONSTRATION.txt Each standalone licence is for one buyer or legal entity's internal staff, agents and CI use. No customer declarations are uploaded. No redistribution, external API resale, updates, monitoring or support SLA. Existing snapshot offers and subscriptions do not include these two licences. Checks concern supplied declarations; no live-permission inspection, enforcement, proof that records exist or certification. Seven complete evidence packs stay free: GitHub + Playwright permission boundaries; Notion + Slack access/data handling; GitHub/Slack/Cloudflare audit/export coverage; three dated Next.js advisory assertions; SonarQube/Snyk/Semgrep scanner trust; telemetry redaction gaps; GitHub release acceptance. These are dated documentation reviews or frozen source assertions, not independent tool tests or current safety assessments. Existing GBP 5 Single Request saves a version-bound public pack, or delivers the original Agent Tool Evaluation & Integration executable kit. GBP 19 Evidence Receipt also adds an unsigned delivery record. Plus applicable VAT. Eligible Research (GBP 29/month + VAT) and Developer/API (GBP 149/month + VAT) subscriptions retain their existing limits; an eligible pack or original kit uses one query. No continual refresh or permanent-retention promise. Public MCP discovery is free, unauthenticated and read-only: https://varexis.tech/mcp Connect: https://varexis.tech/index-connect Purchase or recover: https://varexis.tech/index-access Agent contract: https://varexis.tech/varexis-index/agent-payments.json Hosted Stripe and compatible authorised MPP/Stripe SPT purchasing use separate authenticated paths. Agents require owner spending authority for the exact tax-inclusive quote and required provider authentication; not every agent or wallet is compatible. Retrieve saved purchases or use eligible entitlements before buying. Recover uncertain payment with the original key and matching result endpoint; retain the original payment credential for supported retries. Never buy again to repair uncertain delivery. Payment adds no fresh investigation, independent assurance or deployment approval.
Ask questions about Claude Code, Cursor, Codex and MCP — get answers grounded in their official docs, with citations. A hybrid RAG service that AI agents call through two MCP tools (or over REST). It indexes ~600 pages of official documentation, refreshes itself daily, and every design choice is backed by an experiment.
Vigilia watches your live app, explains every problem in plain language and writes the fix prompt. Your AI fixes it; Vigilia confirms with real traffic. Vigilia watches web apps that are live with real users, including apps built with Lovable, Bolt, v0, Cursor and Claude Code. It catches errors, failed requests and downtime, explains each problem in plain language, and writes a fix prompt for it. Connect Vigilia to Claude and ask what's broken. Claude lists your open incidents worst first. For each one it reads the plain-language diagnosis, who it affects, the technical evidence (error, page, failing request, stack frames and what the visitor did right before) and Vigilia's fix prompt. In Claude Code or another coding agent, Claude can then fix the cause in your own codebase. Once you've deployed, it marks the incident fixed, and Vigilia watches real traffic to confirm the error stayed away. If it comes back, the incident reopens as a regression. You can also ask how an app is doing (uptime, open incidents, today's traffic), get the exact install snippet for a new project, and check that a live site is running Vigilia. Vigilia never reads or changes your code: the fixing happens in your session, by your AI, in front of you. The only tool that changes anything is marking an incident fixed (the install check just records its result on the app), and you can connect with read-only access. Your data is stored in the EU. Emails, tokens and card numbers are stripped from what visitors' browsers send, and only that scrubbed error context is sent to Anthropic to write the diagnosis. Requires a Vigilia account. The free plan covers one app; reporting backend errors (Supabase, Next.js routes, Workers) is part of Pro.
