Mrd MCP server

• ask_datasheetFree

  Ask 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.

• build_budgetFree

  Engineering 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.

• check_fitFree

  Check 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 or the unregulated bus against each unit supply range, EPS charge current against the battery limit, satellite envelope against the deployer envelope for its form factor, on-board computer against unit data interfaces, board stack format, free volume, radio against antenna and ground station (frequency, band, connector, protocol and modulation), antenna against ground station polarization, GNSS receiver signals against the GNSS antenna band, magnetorquer coil current against the driver channel, PPU output power against the electric thruster, 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.

• design_stackFree

  Assemble 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).

• explain_propertiesFree

  What 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.

• find_data_gapsFree

  What 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.

• get_component_specsFree

  The 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_digestFree

  Facts 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.

• match_componentsFree

  Reverse 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.

• search_datasheet_factsFree

  One 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).

Mrd: common questions

Is Mrd MCP server safe?

Yes, by our scan: it is graded A (88/100). Read the Mrd safety report

How do I install Mrd?

It runs remotely at newspacemarket.com. Add it to Claude Code, Claude Desktop or Cursor with the snippets above, or call it through the mcp.market gateway without installing anything.

Does Mrd need an API key?

Yes. The registry entry asks for MRD_API_KEY.

Is Mrd maintained?

The last commit was 6 days ago (2026-09-14). The latest release is v1.2.0.

Is Mrd up?

100% of our last 1 checks got an answer. We check remote servers about four times a day.

What can I use instead of Mrd?

Servers from other publishers that do the same job: jDocmunch MCP server, Brandfetch MCP server and Bussin MCP server. Compare all Mrd alternatives.
