Context tax

Connecting this server adds ~6,661 tokens of tool definitions to every model turn (heavy, 12 tools). Measured 2026-10-19 via its hosted endpoint; o200k tokenizer, worst case for clients that load all tools up front. How we measure

Tools (12)

• edit_project2,778 tok

  Changes a project kept here, by a list of ops applied in order: add_part, update_part (move, turn, change value or ref), remove_parts, add_wire (from/to, or a `path` of holes made into one wire per leg), update_wire, remove_wires, set_board, add_cuts / remove_cuts (stripboard), set_pad. If any op can't be done, none are. Returns what changed, where the pins of added or moved parts landed, and the board checked as validate_project does (with any expectNets remembered for it); when it has no errors, also its nets. get_project returns the whole file. The goal is a board that's right, looks neat a

• make_share_link713 tok

  Turns a project into a link that opens it in Perfboard Designer: the project travels inside the link, so it works without any server. Give the link to the user. Also returns `image`, the address of an SVG picture of the board (as the editor draws it), for showing it where images from links display, e.g. in Markdown (not in Claude or ChatGPT, which don't load them: show_board shows the board there). With store, the project is also stored on the Perfboard Designer server under a short id, and `stored` gives a short link to it, its file and its pictures (SVG and PNG): give the user both links. Th

• validate_project503 tok

  Checks a project file and lists every problem with where it is: entries the editor would leave out, unknown parts, pins off the board, two parts' pins or leads in one hole, overlapping parts, wires that connect nothing (a loose end, or no pins on their net), duplicate wires, a two-lead part with both leads on one net (shorted out), a wire passing over a pin or lead without ending there (so not joined to it), IC pins and two-lead parts' leads connected to nothing, supply rails shorted together, and on a stripboard, pins shorted by a strip or sitting in a cut hole. With expectNets, every connect

• render_board473 tok

  Draws the board as text, one cell per hole with column and row numbers: each part's pins by a key letter and pin number (a1, a2...), holes under a part's body, wire ends, the holes a wire runs over without joining them, strip cuts and marked holes. Below it, which part each key is and every wire with its ends and net. Use it to see where there's free space and how wires run before placing parts or routing more. With format "png", a picture of the board as the editor draws it instead, to see how it looks: parts' bodies and where they reach, labels, wire colours. To show the user the board, use

• new_project314 tok

  Starts a project kept here under a projectId: a blank board, or one of the example projects (perfboard://examples/...) to copy from. Returns the projectId and the project file. Then add parts and wires with edit_project, and pass the projectId to every other tool instead of the whole file.

• get_nets289 tok

  Which pins the board connects: every net with its name (from its pins, e.g. GND), its pins ("U1.8 VCC" for a chip's pin, "D1.K" or "C1.+" for a polarized lead, "R1.1" otherwise) and the wires on it (indexes into wires). Also pins connected to nothing, wires that connect no pins, junctions (holes where three or more things are joined) and crossings (where a wire goes over another wire or over a hole without joining it). Wires are insulated jumpers: a wire joins only the holes at its two ends, so crossings are information, not connections or shorts. On a stripboard the strips connect too.

• show_board260 tok

  Shows the user a picture of the board right in the conversation, as the editor draws it, with a button that opens it in Perfboard Designer. Only in clients that show MCP Apps (e.g. Claude, ChatGPT); elsewhere the user sees nothing, so give them make_share_link's link too. The picture goes to the user, not to you: to look at the board yourself, use render_board.

• get_pin_positions248 tok

  Where every placed part's pins land, as [column, row] holes, with pin numbers and labels (e.g. U1 pin 8 VCC), after rotation, plus holes a part's body covers. Use it to route wires to the right holes. The project file doesn't store these: they follow from each part's anchor, rotation and footprint.

• list_parts213 tok

  Lists the parts a project can place. Without a query: every part, grouped by category, as its id with its name and pin count; call it this way once to see what there is. With a query: the parts whose id, name, category or keywords contain all its words, or the closest ones when none do. Each part's `id` is its definitionId in the project file; use get_part for its pins and how to place it.

• get_part156 tok

  Everything needed to place parts: for each, which project file list it goes in, its pins (offsets from pin 1 at rotation 0) and pin labels, polarity, value unit, holes its body covers, and an example entry. Ask for every part you use in one call with `ids`.

• read_share_link135 tok

  Reads the project out of a Perfboard Designer share link (any of its forms: z=, json= or src=, which is downloaded; a stored project's short link too), so you can look at or change a board the user shared. Returns the project as a version 3 project file, kept here under the projectId it returns: change it with edit_project.

• get_project72 tok

  The whole project file of a project kept here, as the editor would save it (version 3), one entry per line.
