Tools & capabilities

Ocular tools 8

  • analyze_imageAnalyze a general image and return structured JSON for a coding agent.
  • extract_text_from_imageExtract OCR text from screenshots, documents, tables, terminal output, or code images.
  • analyze_ui_screenshotAnalyze a webpage, app, UI, or design mockup screenshot for frontend implementation work.
  • diagnose_error_screenshotAnalyze error, terminal, console, browser, or build failure screenshots.
  • compare_ui_screenshotsCompare two UI screenshots and return implementation-useful visual differences.
  • extract_table_from_imageExtract visible table data from an image as structured JSON, Markdown, or CSV-oriented output.
  • analyze_chart_imageAnalyze a chart image and return labels, trends, approximate values, and limitations.
  • create_upload_sessionReturns upload instructions for the binary side channel (use this to analyze LOCAL image files without base64 corruption). Before uploading, verify the local file exists and is non-empty with Bash (e.g. `ls -la <path>` or `test -f <path> && stat -c %s <path>`). Then PUT the raw bytes to the returned upload_url with curl --data-binary (NOT base64); the response gives a file_id to pass to any vision tool. Stateless -- call once to learn the endpoint.

Openclaw MCP tools 7

  • openclaw_chatSend a message to OpenClaw and get a response
  • openclaw_statusGet OpenClaw gateway status and health information
  • openclaw_chat_asyncSend a message to OpenClaw asynchronously. Returns a task_id immediately that can be polled for results. Use this for potentially long-running conversations.
  • openclaw_task_statusCheck the status of an async task. Returns status, and result if completed.
  • openclaw_task_listList all tasks. Optionally filter by status, session, or instance.
  • openclaw_task_cancelCancel a pending task. Only works for tasks that haven't started yet.
  • openclaw_instancesList all configured OpenClaw instances. Shows instance names, URLs, and which is the default. Use instance names in other tools to target a specific OpenClaw gateway.
