    How to connect

    How to connect mrd to Claude

    The server address to paste into Claude settings:

    https://newspacemarket.com/mrd-connect/mcp

    1. Open Claude (claude.ai or the desktop app).
    2. Go to Settings → Connectors.
    3. Click Add custom connector.
    4. Paste the server address copied below into Remote MCP server URL and click Add.
    5. In a chat, click + → Connectors and switch the new connector on.

    Custom connectors are available on Free, Pro, Max, Team and Enterprise plans (Free is limited to one). On Team and Enterprise an organization Owner adds the connector first under Organization settings → Connectors.

    Authorization

    After you click Add, a sign-in window for the service opens. Sign in with your own account and approve access. Claude never sees your password.

    How to connect mrd to ChatGPT

    The server address to paste into ChatGPT settings:

    https://newspacemarket.com/mrd-connect/mcp

    1. Open ChatGPT in a browser (chatgpt.com). A Plus, Pro, Business, Enterprise or Edu plan is required.
    2. Turn on developer mode once: Settings → Apps → Advanced settings → Developer mode.
    3. Open Settings → Connectors and click Create.
    4. Fill in the form: Name (anything), Description (one line about what the service does), MCP server URL (copy it below).
    5. Under Authentication choose OAuth if the service requires sign-in, otherwise None. Click Create.
    6. In a new chat open + → Apps/Connectors and enable the connector.

    OpenAI has renamed this section before (Connectors → Apps/Plugins). If the label differs, search settings for "developer mode". On Business/Enterprise workspaces an admin must allow custom connectors first.

    Authorization

    On first use ChatGPT opens the service's sign-in window. Sign in and approve access.

    How to connect mrd to Cursor

    The server address to paste into Cursor settings:

    https://newspacemarket.com/mrd-connect/mcp

    Fastest: click Open in Cursor below and confirm the prompt.

    Manually:

    1. In Cursor open Settings → Cursor Settings → MCP and click Add new global MCP server.
    2. Paste the JSON copied below into ~/.cursor/mcp.json (per project: .cursor/mcp.json in the repo root).
    3. Save the file. The server appears in the MCP list; authorize it there if asked.

    Authorization

    If the service needs sign-in, an authorize button appears next to the server in the MCP list.

    Server tool list (10)

    Raw names from tools/list. Only developers need these.

    explain_propertiesWhat every property of a product category means: definition, how it is measured and what goes into the measurement condition, how to use it when selecting, what it is commonly confused with, typical range and related properties. Call this before interpreting specs of an unfamiliar category.
    match_componentsReverse search over a typed spec layer: pass a category and engineering requirements, get every catalogued item grouped as A (meets all stated requirements), B (fails a named requirement, both figures quoted) or C (could fit, data missing). Verdicts cite the datasheet page. Omit parameters you do not care about. Categories: reaction-wheels, star-trackers, obc-computers, batteries, radios, solar-panels, propulsion, sun-sensors, magnetometers, magnetorquers, imus-gyros, gnss-receivers, eps, deployers, thermal, antennas, sdr-modems, cameras, structures, ground-stations, sadm, tanks-valves, separation-systems, pointing-mechanisms.
    build_budgetEngineering budget for a component stack: pass product ids (from the other tools) and your bus voltage, get total mass, total steady-state power, per-item data interfaces, voltage-compatibility verdicts and an honest list of what could NOT be counted because the vendor does not publish it. Use it to assemble and sanity-check a subsystem, e.g. 3-4 reaction wheels for an ADCS.
    get_component_specsThe full typed layer of a category — every item with every value (number, canonical unit, bound, measurement condition, datasheet source page, confidence L0/L1) plus the property dictionary grouped by interface port (perf/power/data/mech/thermal/env/supply) — for arbitrary comparison, budgeting or trade studies on your side.
    get_datasheet_digestFacts machine-read from a product datasheet, by section (identity, performance, electrical, interfaces, mechanical, thermal, environmental, qualification, lifetime, options, compliance, commercial). Each fact carries unit, condition, the page and a verbatim quote it was verified against (confidence L0) plus a link into the PDF. Use it for what the typed layer does not hold: connectors, protocols, survival temperature, vibration, radiation, heritage, options, export control, lead time. Pass product_id from match_components or a product name.
    search_datasheet_factsOne fact key across a whole category: which products state it in their datasheets and what value — e.g. connector, data_interface, protocol, survival_temperature, tid_tolerance, flight_heritage, trl, export_control, lead_time, price, design_life. One row per product with page and quote. Reports coverage (how many products of the category have a digested datasheet).
    ask_datasheetAsk a product datasheet a question and get the closest excerpts with page numbers (pre-indexed text), or scan ALL datasheets of a category for an exact term (term + category) and get the exact list of products mentioning it with an excerpt each.
    design_stackAssemble a whole spacecraft bus from a plain-language task: the service plans the subsystems, matches every item deterministically against the stated requirements, computes the mass/power budget and writes an evidence-bound rationale. Pass fixed = product ids you have already chosen (from match_components or get_datasheet_digest): they stay in their subsystems, are checked against the requirements (selected.fixed, fixed_verdict, fixed_fails) and the rest is assembled around them. LLM-backed and rate-limited (6/min, 30/h anonymous).
    find_data_gapsWhat is missing for a product, a company or a category and where to get it: in_digest (already read from the datasheet — value, page), in_datasheet_text (the datasheet mentions it — page, excerpt), not_in_datasheet (ask the vendor), no_datasheet (ask the vendor for a datasheet). For vendors: what to publish; for buyers: what to ask.
    check_fitCheck whether a set of products docks together, by the interface template of each product type: deployer and CubeSat structure form factor and satellite mass, separation system and spacecraft mass, solar panel size and EPS solar input (Voc/Vmp, power), battery and EPS, EPS output rails against each unit supply range, on-board computer against unit data interfaces, board stack format, free volume, radio against antenna and ground station (frequency, band, connector, protocol), array drive against panel power, propulsion propellant against tank media, steady power budget. Verdicts fits / conflict / check / unknown, plus ask_vendor: exactly which values are missing to decide.
