Tools & capabilities
Qwen DAP MCP tools 18
debug_sessionsUse this tool to list, create, or close isolated DAP sessions before routing other debugger tools with sessionId. Omit sessionId on normal debug tools only when the backward-compatible default session is intended; do not use a global session selector for concurrent work.debug_compare_runsCompare bounded runtime evidence from two existing stopped DAP sessions. Use this for baseline or known-good versus candidate or failing differential debugging after both sessions have reached comparable stops. It compares stack identities, locals, registers, exception state, symbol health, and modules semantically; non-null raw address-only changes are marked unstable rather than causal evidence. Do not use it to launch, resume, or alter either target; prepare both runtime states with the normal lifecycle tools first.debug_snapshotCapture bounded evidence from the current stopped debug state without resuming execution. Use this when an agent needs raw stack, locals, registers, exception details, modules, or nearby instructions; prefer debug_diagnose_stop when you also want ranked crash hypotheses and project-frame selection. This is read-only with respect to the debuggee and returns best-effort evidence plus collection errors for optional data that an adapter cannot provide.debug_statusInspect debugger lifecycle state, the selected stop, recent DAP events, and bounded adapter stderr without changing target execution. Use this to determine whether a session is initialized, running, stopped, postmortem, exited, or failed before choosing another debug tool; it is diagnostic only and does not resume, launch, attach, or terminate the debuggee.debug_disconnectEnd the active DAP session and stop its local adapter process. Use this when debugging is finished or the session must be reset; do not call it when more runtime evidence is still needed. With terminateDebuggee=true it may also terminate a live target process, so this operation can destroy the current runtime state and cannot be treated as read-only.debug_run_to_stopRun one live launch or attach through an already initialized DAP adapter until the first stopped, exited, or terminated event. Use this when you need deterministic runtime evidence from a reproduction; do not use it for a postmortem dump or when executing/attaching to the local target is not authorized. Launch mode executes application code and attach mode changes debugger control of an existing process, so normal target side effects may occur before the stop. Returns the request result, terminal/stopped outcome, session status, and a bounded snapshot only when a stopped event is captured.debug_diagnose_stopDiagnose an already stopped live or postmortem debug session without changing execution state. Use this when a debugger has captured the failure and you want project-frame selection, crash classification, operand/register/variable bindings, call-chain provenance, ranked hypotheses, and a fix/rebuild/reproduce/verify plan; use debug_snapshot instead when only raw evidence is needed. The tool is read-only and returns both the bounded snapshot and the derived diagnosis, including collection limitations when optional debugger evidence is unavailable.debug_source_disassemblyCorrelate source locations, disassembly, registers, and pointer-like locals for the raw fault frame and the first likely project-controlled frame. Use this for low-level root-cause evidence when a crash is already stopped and instruction/operand provenance matters; prefer debug_diagnose_stop for a broader ranked diagnosis. This is read-only, does not resume the target, and returns frame-selection reasoning, both correlations, operand bindings, and any best-effort collection errors.debug_this_crashPreferred high-level native crash workflow. Use mode=current for an already stopped session, dump for read-only postmortem analysis, codelldb to discover CodeLLDB, lldb-dap to discover upstream LLVM lldb-dap, gdb to discover GNU GDB built-in DAP interpreter, or live with an already initialized generic DAP adapter. Do not use codelldb/lldb-dap/gdb/live when executing or attaching to the target is not authorized: those modes can run application code and cause its normal side effects, while current/dump only inspect stopped evidence. workflow.stage selects initial diagnosis, verification against a prior baseline, or the bounded autonomous cycle. Returns runtime evidence, diagnosis, verification/autonomous metadata, and debugger status with deterministic fixed/blocked/budget-exhausted outcomes where applicable.debug_causal_traceBuild a bounded consumer-to-writer evidence chain for one suspicious debugger-visible value. Use it after crash or differential evidence identifies a value whose runtime producers matter. It combines the current stopped snapshot with repeated watchpoint writer tracing. Do not use it for frozen dumps or unsafe-to-resume targets, and do not treat an observed writer as automatic proof of root cause.debug_progress_probeSample a live target across short resume/pause intervals to distinguish no observed progress, same-frame execution movement, and probable busy loops. Use it when a process appears hung but a single thread snapshot cannot distinguish blocking from spinning. Do not use it when resuming the target is unsafe; sampling perturbs scheduling and is not proof of application-level progress.debug_runtime_reportCreate a shareable structured report from the current stopped target with normalized crash fingerprinting, Symbol Doctor status, sanitizer stderr correlation, poison-pattern memory hazard detection, ABI register-to-argument mapping, and recent debugger output. Use it only for evidence-driven triage and issue handoff. Do not treat heuristic poison patterns, ABI mappings, or sanitizer text correlation as standalone proof.- +6 more on the listing page
Next AI Draw IO tools 16
get_drawing_guideReturn the drawing guide: XML format, layout, edge routing, style and editing rules. start_session already returns it; call this only if the guide is no longer in your context. With topic, returns a short XML reference for tables, layers or groups.get_shape_libraryGet the style syntax and shape names of a draw.io icon library. Call this BEFORE drawing with cloud, network or other icon shapes, and use the exact names it returns; never guess them. Libraries: - Cloud: aws4, azure2, gcp2, alibaba_cloud, openstack, salesforce - Networking: cisco19, network, kubernetes, vvd, rack - Business: bpmn, lean_mapping - General: flowchart, basic, arrows2, infographic, sitemap - UI/Mockups: android, material_design - Enterprise: citrix, sap, mscae, atlassian - Engineering: fluidpower, electrical, pid, cabinets, floorplan - Icons: webiconsstart_sessionStart a new diagram session, or continue a saved one with session_id, and open the browser for real-time preview. Starts an embedded server and opens a browser window with draw.io. The browser will show diagram updates as they happen. The result includes the drawing guide; follow it when drawing.list_saved_diagramsList the diagrams saved by earlier sessions (auto-save files), newest first, with their pages. Continue one with start_session session_id=<id>; the file path also works with load_diagram.create_new_diagramCreate a NEW diagram, REPLACING the whole document: every page and any unsaved user changes (the previous state stays in History). To add a tab use add_page; to change cells use edit_diagram. Before using icon shapes (AWS, Azure, GCP, Kubernetes, Cisco...), call get_shape_library first. Follow the drawing guide returned by start_session (call get_drawing_guide if it is no longer in your context). Pass screenshot: true on the last call of a complex diagram to check the result. Accepted xml: 1) Only the mxCell elements of one page (recommended). The server adds <mxfile>, <mxGraphModel>, <root> and the root cells "0" and "1": <mxCell id="2" value="Shape" style="rounded=1;" x="40" y="40" w="120" h="60"/> 2) A bare <mxGraphModel> with <root> (one page). 3) A full <mxfile> with one or more <diagram> pages. Every page's <root> must start with <mxCell id="0"/><mxCell id="1" parent="0"/>. Rules: cells are siblings (never nested), ids are unique per page and start from "2", parent only for shapes inside a container, no XML comments, and shapes stay within x 0 to 800 and y 0 to 600. A style used by several cells is defined once with <mxStyle name="..." value="..."/> before the cells and used by name (see the drawing guide); html=1 and whiteSpace=wrap are added automatically. To clear the canvas to one blank page, send only the two root cells <mxCell id="0"/><mxCell id="1" parent="0"/>; the previous diagram stays in History.load_diagramLoad a .drawio diagram into the current session, REPLACING the entire diagram (all pages). To change an existing file, load it here, edit with edit_diagram, then export_diagram to the same path; never rewrite the file by hand. Provide ONE of two mutually exclusive sources: 'path' (the server reads the file from disk — you do NOT need to read the file yourself or pass its XML through create_new_diagram) or 'xml' (the raw file content you already have — from another tool, a repository read, or an API response — so no temporary file needs to be written first). Both accept plain XML and draw.io's compressed save format. .drawio.svg (Editable SVG, the format export_diagram writes) is accepted too; .png files (also draw.io's editable PNG) and plain .svg files cannot be loaded. After loading from 'path' (or from compressed 'xml'), call get_diagram before edit_diagram — you haven't seen the file's cell IDs yet. Plain-XML 'xml' content you supplied yourself is already known and can be edited immediately.edit_diagramEdit a specific page in the current diagram by ID-based operations (update/add/delete cells). All-or-nothing: if any operation fails, nothing is applied and every failure is listed. Freshness: the server remembers the last diagram state you have seen, and rejects this call only if the user edited the diagram in the browser since then. You do NOT need to call get_diagram before every edit: a rejected call changes nothing and includes the current XML of the page, so you can rebuild your operations and retry. Call get_diagram first only when you don't know the current diagram content (cell IDs, structure) — e.g. the diagram wasn't created in this conversation, or you're unsure your memory of it is accurate. Multi-page targeting: - page_id / page_name / page_index are optional; when all omitted, the FIRST page is targeted - Use list_pages to discover what pages exist Operations: - add: Add a new cell. Provide cell_id (new unique id within the page) and new_xml. One cell per operation. - update: Replace an existing cell by its id. Provide cell_id and complete new_xml. - delete: Remove a cell by its id. Only cell_id is needed. Its children and connected edges are deleted too, so give only a container's id. For add/update, new_xml is the complete mxCell (inside its <object> wrapper when it has custom data, see the drawing guide) in the compact form (a shape with x, y, w, h; an edge with source and target). No XML comments. Every " inside new_xml must be escaped as \" in the JSON. Example - Add a rectangle on the default (first) page: {"operations": [{"operation": "add", "cell_id": "rect-1", "new_xml": "<mxCell id=\"rect-1\" value=\"Hello\" style=\"rounded=1;\" x=\"100\" y=\"100\" w=\"120\" h=\"60\"/>"}]} Example - Delete a cell on the default page: {"operations": [{"operation": "delete", "cell_id": "rect-1"}]}get_diagramGet the current diagram XML (fetches latest from browser, including user's manual edits). Call this when you don't know the current diagram content (cell IDs, pages, structure) — e.g. before editing a diagram you didn't create in this conversation, or after edit_diagram was rejected because the user changed the diagram in the browser. Returns the full <mxfile> by default. If a page selector is provided, returns just that page's <mxGraphModel> embedded in a one-page <mxfile> wrapper.get_selectionReturn the cells the user has selected in the preview: their ids and labels, for edges the source and target ids, for shapes the position and size, and the page they are on. Call this when the user refers to what they selected ("this box", "these arrows", "the selected shapes"), then act on the ids with edit_diagram. Says when nothing is selected. Needs the preview tab to be open.screenshot_diagramRender the diagram in the preview and return it as a PNG image, so you can see your own result. Call this once after drawing or heavily editing a complex diagram, then fix overlaps and edges that cross shapes. Without a page selector it shows the page on screen; with one it renders that page without changing what the user sees. Needs the preview tab to be open.export_diagramExport the current diagram to a file. Supports .drawio (XML), .png, .svg, and .drawio.svg (an SVG with the diagram embedded, which draw.io and load_diagram can open again). The format is auto-detected from the file extension, or can be specified explicitly. Images get a 20 px margin; a PNG has a white background (or the page's own background color) unless transparent is true. Multi-page behaviour: - .drawio with NO page selector: writes the full <mxfile> (all pages). - .drawio with a page selector: writes a single-page <mxfile> containing only that page. - .png / .svg with NO page selector: exports the currently active page in the browser. - .png with a page selector: renders that page without changing what the user sees. - .svg / .drawio.svg with a page selector: temporarily loads that page into the browser, captures it, then restores the full document (the user sees a brief flicker).list_pagesList every page (tab) in the current diagram. Returns each page's id, name, 0-based index, and cell count. Use this to discover what pages exist before targeting one with edit_diagram, get_diagram, export_diagram, rename_page, or delete_page.- +4 more on the listing page
