Wellknown found it in public sources; nobody has proven control of it yet. Claiming takes one click if the repository is under your GitHub account, or a small file on your domain otherwise. Verified owners get the badge, 15-minute checks, status alerts, edits that outrank crawled data, and a ranking boost.

Agents can do it too: POST https://wellknown.network/api/v1/claims with {"agent":"blockwerk","method":"well_known_file"} — machine-readable steps at claim.json, guide at /docs/claim.

Tools observed via MCP handshake

describe_canvas — Returns a structured description of all blocks and connections currently on the canvas. Set "compact" to true for a token-efficient summary.
get_available_blocks — Returns the block types in the library with their descriptions, configurable parameters, and exact input/output port IDs. Without a filter it returns a compact
add_block — Add a new block to the canvas. Returns the new block ID.
connect_blocks — Connect an output port of one block to an input port of another. Automatically resolves common port aliases (e.g., "in" -> "signal" for uPlotDisplay, "in" -> "e
update_params — Update one or more parameters of an existing block.
delete_block — Delete a block and all its connections from the canvas. This is a destructive action that asks the user for approval in the BlockWerk tab.
load_diagram — Atomically replaces the entire canvas with a complete diagram defined as a BlockWerk project JSON string. The JSON has a "blocks" array (each block needs a uniq
export_diagram — Exports the current canvas project as a complete BlockWerk JSON string.
get_share_link — Returns a link that opens the current diagram on the BlockWerk canvas. The whole project travels compressed inside the URL, so it needs no account and nothing i
clear_canvas — Remove all blocks and connections from the canvas. This is a destructive action that asks the user for approval in the BlockWerk tab.
tidy_layout — Automatically rearrange all blocks on the canvas into a clean, left-to-right flow.
batch_commands — Executes multiple canvas manipulation and background job commands in a single round-trip. Use "handle" strings to refer to blocks added earlier in the same batc
analyze_topology — Analyzes the block diagram structure: detects feedback loops, signal paths, and system order.
get_signal_data — Returns time series data from a Scope block output for analysis.
calculate_metrics — Calculates step response metrics from signal data: rise time, settling time, overshoot percentage, and steady-state error.
get_analysis_measurements — Retrieves the currently active pinned measurements and their computed values across plotted signals in the Analysis panel.
evaluate_spec_mask — Evaluates signal data against automated design specifications and tolerance corridors (rise time, settling time, overshoot %, steady-state error, min/max limits
get_architect_memory — Returns the persistent memory object of the Architect.
update_architect_memory — Updates the persistent memory of the Architect. Provide a JSON object with keys to update/merge.
validate_engineering_units — Checks the consistency of engineering units across the diagram. Detects incompatible connections and missing units.
validate_canvas — Performs pre-flight topological and numerical integrity checks on the canvas. Detects unconnected required input ports, isolated blocks, parameter domain anomal
get_canvas_preview — Captures a visual screenshot preview of the canvas branded with the official BlockWerk watermark badge and returns the live interactive URL to view and edit the
get_templates — Lists the built-in, verified BlockWerk diagrams: classic control systems (PID loop, cruise control, inverted pendulum), signal processing, electrical and physic
load_template — Replaces the entire canvas with one of the built-in verified diagrams, by id from get_templates. The template carries its topology, parameters and simulation se
run_simulation — Triggers a new simulation run with the current canvas state and settings, refreshing the signal data.
sweep_parameter — Runs simulations across a list of values for one parameter, returning control quality metrics (IAE, overshoot, settling_time, steady_state_error) per value. Req
optimize_parameters — Finds the optimal value for a single parameter using golden-section search. Minimizes IAE (integral absolute error), overshoot, or settling_time within a [min,
optimize_multi_parameter — Optimizes 2–6 parameters simultaneously using Nelder-Mead simplex search, for example Kp, Ki and Kd of a PID controller at once.
auto_tune_pid — Automatically tunes a PID controller using the Ziegler-Nichols ultimate cycle method. Finds the ultimate gain (Ku) and oscillation period (Tu) via binary search
identify_fopdt — Analyzes a step response from a plant to identify its First-Order Plus Dead Time (FOPDT) parameters: Gain (K), Time Constant (tau), and Dead Time (theta). Requi
start_optimization — Start a parameter optimization job in the background.
get_job_status — Check the status and progress of a background job.
cancel_job — Cancel a running background job.
list_jobs — List all recent background jobs and their status.
explain_simulation — Analyze the last completed simulation and return a structured diagnosis: signal anomalies (NaN, divergence, oscillation), solver health (rejection rate, efficie
get_bode_data — Computes magnitude and phase frequency response (Bode data) between two blocks. Traces path backwards from outputBlockId. Returns analytic response if the path
get_fft_data — Computes FFT (frequency spectrum) of a Scope signal. Returns frequencies and magnitudes.
get_engine_status — Returns the simulation engine status, including supported solvers, active background jobs, and compilation/WASM capabilities.
generate_code — Generates standalone production code (C++, Python, Rust) from the current canvas diagram. Returns structured code files, interfaces (inputs/outputs), execution
undo_last_ai_action — Undoes the last canvas modification made by the AI (add block, connect, delete, update parameter).
redo_last_ai_action — Redoes the last undone canvas modification.
get_ai_history — Returns the list of recent canvas operations performed by the AI, showing what can be undone.
