# LeanTools > Every tool your agent needs. One lean endpoint. LeanTools gives AI agents eight products behind one endpoint and one API key: LeanModel (OpenAI-compatible text, image, speech, music, video, avatar and realtime audio models), LeanMemory (structured, semantic and event memory with file storage), LeanData (queryable datasets), LeanVision (vision monitoring for CCTV), LeanBrowser (managed headless browsers), LeanMachine (ephemeral Linux sandboxes), LeanConnect (connectors, web search and email with approvals) and LeanTracker (AI-native issue tracking, a desktop app). Web search, email, data and connectors are MCP tools; the other products are REST and WebSocket on the same host and key. Agents pay per call from prepaid credits; workspaces control which products are enabled, set spend caps and approve sensitive writes. Key facts: - MCP endpoint (Streamable HTTP): /mcp with header `Authorization: Bearer `. - REST base: /api/v1 (OpenAPI at /swagger). Same catalogue as MCP, plain HTTP status codes. - Keys come from the workspace console at /app (Settings → API keys); sign-up at https://leantools.ai/signup gives starter credit and a default key. - Billing: prepaid credits, unit prices per tool (https://leantools.ai/pricing), no seat fees; failed calls are not charged. - Every documentation page below has a Markdown twin at the same path with `.md`; `Accept: text/markdown` on the HTML URL works too. The whole documentation in one file: https://leantools.ai/llms-full.txt. ## Products - [LeanModel](https://leantools.ai/products/model): OpenAI-compatible text, image, speech, music, video, avatar and realtime voice models, metered on the same credits as the rest of your stack. - [LeanMemory](https://leantools.ai/products/memory): A memory that learns from use: structured, unstructured and event data in one place, with recall that gets more accurate the more your agents work. - [LeanMemory benchmark](https://leantools.ai/products/memory/benchmark): LeanMemory against conventional and state-of-the-art RAG on five public question sets, 1,000 questions each, before and after it learns from use. - [LeanData](https://leantools.ai/products/data): Datasets your agents can discover, query and subscribe to, through one consistent interface. - [LeanVision](https://leantools.ai/products/vision): Continuous vision monitoring for CCTV. Describe what matters and get events the moment it happens. - [LeanBrowser](https://leantools.ai/products/browser): Managed headless browsers your agents can drive to capture, extract and automate the web. - [LeanMachine](https://leantools.ai/products/machine): Ephemeral Linux sandboxes for code, builds and file work. Ready in seconds, gone when the job is done. - [LeanConnect](https://leantools.ai/products/connect): Connect agents to the apps your business runs on, with credentials kept safe and every write under your control. - [LeanConnect connectors](https://leantools.ai/connectors): 112 connectors with 540+ actions (MCP tools named connector..), by category: AI models and language (Anthropic, Azure OCR, Azure OpenAI, DeepL, DeepSeek, Google Gemini, Google Translate, Groq, Mistral AI, OpenAI), Messaging and meetings (Discord, Mattermost, Microsoft Teams, Slack, Telegram, Twilio, WhatsApp Business Cloud, Zoom), Email (Gmail, Mailgun, Microsoft Outlook, Postmark, SendGrid), CRM and sales (Google Contacts, HubSpot, Pipedrive, Salesforce, Zoho CRM), Customer support (Freshdesk, Freshservice, Help Scout, Intercom, Zammad, Zendesk), Marketing (ActiveCampaign, Brevo, Facebook Lead Ads, GetResponse, Google Ads, Google Business Profile, Kit (ConvertKit), Mailchimp, MailerLite), Social media (LinkedIn, Meta, Reddit, TikTok, X, YouTube), Projects and tasks (Asana, ClickUp, Google Tasks, Jira, Linear, Microsoft To Do, monday.com, Todoist, Trello), Docs and spreadsheets (Coda, Confluence, Google Docs, Google Sheets, Google Slides, Microsoft Excel, Microsoft Excel (SharePoint), Notion), Calendars and time (Cal.com, Calendly, Clockify, Google Calendar, Harvest, Toggl Track), Files and storage (Amazon S3, Box, Dropbox, Google Drive, Microsoft OneDrive, SharePoint), Databases and analytics (Airtable, Amazon DynamoDB, Baserow, Cloud Firestore, Google Analytics 4, Google BigQuery, NocoDB, PostHog, Snowflake, Supabase), Developer and cloud (Bitbucket Cloud, Cloudflare, GitHub, GitLab, Netlify, Sentry), Websites and design (Contentful, Figma, Webflow, WordPress), Commerce and finance (Chargebee, Paddle, PayPal, QuickBooks Online, Shopify, Stripe, WooCommerce, Xero), Identity and admin (Google Workspace Admin, Microsoft Entra ID, Okta), Forms and surveys (Jotform, SurveyMonkey, Typeform). - [LeanTracker](https://leantools.ai/products/tracker): AI-native issue tracking: testers capture rich reports, and coding agents pick them up and fix them. ## Guides - [A store that watches itself](https://leantools.ai/blog/a-store-that-watches-itself): How LeanVision, LeanMemory and LeanConnect combine into an agent that notices a queue forming, checks it against how past rushes played out, and alerts the floor manager before customers walk away. - [Research that remembers](https://leantools.ai/blog/research-that-remembers): How LeanBrowser, LeanData and LeanMemory give a research agent reliable sources, figures it can cite, and a memory of what it has already learned. - [From bug report to fix](https://leantools.ai/blog/from-bug-report-to-fix): How LeanTracker, LeanMachine and LeanBrowser take a tester's report to a verified fix: a report with full context, a clean environment to reproduce it in, and a browser check before hand-back. ## Getting started - [LeanTools documentation](https://leantools.ai/doc/index.md): Every tool your agent needs. One lean endpoint. LeanTools hosts native tools and connectors for AI agents; these docs cover the quickstart, MCP server, tools API, REST reference, billing and the workspace console. - [Quickstart](https://leantools.ai/doc/quickstart.md): From an empty browser tab to an agent that searches the web through LeanTools, in five steps: sign up, connect your harness to the MCP endpoint, make the first call, read the activity log. - [Authentication](https://leantools.ai/doc/authentication.md): API keys, bearer headers, key scopes and spend caps, rotation and revocation, and how the console session differs from agent credentials. - [Credits and billing](https://leantools.ai/doc/credits.md): Prepaid credits, meters and unit prices, caps and budgets, auto-reload, invoices and the account endpoints. ## Agents - [MCP server](https://leantools.ai/doc/mcp.md): Connect Claude, Codex, Cursor or any MCP client to the LeanTools endpoint: transport, authentication, tools/list, tools/call, annotations and errors. - [Tools API and native tools](https://leantools.ai/doc/tools.md): The same catalogue as MCP over plain HTTP: list, describe and call native tools with real status codes, plus every native tool LeanTools hosts. - [Connectors and approvals](https://leantools.ai/doc/connectors.md): LeanConnect's third-party connectors, stored credentials, guardrails, human-in-the-loop approvals for writes, and the approval polling endpoint. - [LeanData](https://leantools.ai/doc/data.md): Datasets and documents agents can query through LeanData: the data catalogue, queries, streaming results, subscriptions and billing per row. ## REST API - [REST API reference](https://leantools.ai/doc/api.md): Direct, typed access to each LeanTools service: web search and email (LeanConnect), LeanBrowser, LeanModel (text, image, speech, music, video, avatar and realtime audio models), embeddings, LeanMachine, LeanVision and LeanMemory (warehouse, vectors, events and storage). - [Errors](https://leantools.ai/doc/errors.md): Every error code LeanTools answers with, what it means, and what an agent should do about it. ## Console - [Workspace console](https://leantools.ai/doc/console.md): The customer console: API keys, members and roles, billing and auto-reload, tool switches, connector credentials and approvals. ## Optional - [Pricing](https://leantools.ai/pricing): unit prices, starter credit, invoices. - [Contact](https://leantools.ai/contact): sales, support, security reports. - [Privacy](https://leantools.ai/privacy) and [Terms](https://leantools.ai/terms). - [Documentation manifest](https://leantools.ai/doc/index.json): machine-readable list of every page and rendition.
