Common questions

Is SheetsData safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: SHEETSDATA_API_KEY

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.4.0) reached the registry 21 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

SheetsData MCP

Electronic component datasheets for AI agents — pinouts, specs, package info and design checks from manufacturer PDFs.

SheetsData is a hosted MCP server. Your agent finds parts across JLCPCB, Mouser and DigiKey, reads any section of a part's datasheet as text and tables, compares parts, checks a BOM, and checks your operating conditions against the datasheet's ratings. The agent never sees a PDF, and you don't have to find or paste one.

Server URL:  https://mcp.sheetsdata.com/mcp   (Streamable HTTP)

Sign-in: MCP OAuth (browser), or an API key as "Authorization: Bearer "

This repository holds the install configs, the @sheetsdata/mcp stdio proxy for clients that only start local servers, and the Claude Desktop bundle. The server itself is a hosted service.

What it looks like

"Is the TPS54302 fine with 24 V in and 2.5 A out?"

check_design_fit("TPS54302", input_voltage=24, output_current=2.5)

overall: WARNING input_voltage 24 V PASS within the recommended range 4.5–28 V (14.3% margin) datasheet row: "| V I | | 4.5 | 28 | V |" unmatched: output_current

A condition the tool can't find a limit for is listed as unmatched and keeps the verdict at WARNING: a clean PASS means every condition was checked against the datasheet.

"Buck converters that take 24 V in and give at least 2 A" (free):

Tools

Prices are per call and the same on every plan. A call that fails is not charged. Current prices are on sheetsdata.com/pricing.

Tool	Price	What it does
`search_parts`	Free	Find parts by part number or keyword across JLCPCB, Mouser and DigiKey, merged by MPN, with stock, price and datasheet status from each.
`find_parts`	Free	Find parts that meet numeric specs with units (e.g. Vin ≥ 24 V, Iout ≥ 2 A), package or stock; each constraint reports pass, fail or unknown with its source.
`get_part_details`	3¢	A part's key parameters, package, pricing, stock and datasheet status, by MPN or LCSC number.
`check_bom`	3¢	Check up to 20 BOM lines for lifecycle, stock against quantity, single-distributor sourcing, datasheet status and stale prices.
`prefetch_datasheets`	1¢	Start reading up to 20 datasheets at once, so a whole BOM is ready before you ask about it.
`check_extraction_status`	Free	Report how far a datasheet that is still being read has got.
`read_datasheet`	10¢	Any section of a datasheet as text and tables (summary, pinout, electrical, absolute maximum ratings, package, or any heading), or a search within one datasheet.
`search_datasheets`	2¢	Search every datasheet read so far by meaning, e.g. "LDO with PSRR above 70 dB".
`compare_parts`	8¢	Compare 2–5 parts side by side: parameters, package, pricing, stock and datasheet summaries.
`find_alternative`	6¢	Find drop-in and functional substitutes for a part, ranked by spec, package and stock match.
`check_design_fit`	12¢	Check operating conditions against the absolute maximum and recommended ratings: PASS, WARNING or FAIL per condition, with the datasheet row it used.
`analyze_image`	10¢	Read values off a datasheet figure: a characteristic graph, package drawing or pin diagram.
`request_datasheet_upload`	Free	Get a private upload link for a datasheet PDF we couldn't find.
`confirm_datasheet_upload`	50¢	Verify the uploaded PDF (hash, valid PDF, MPN on page one) and read it into your organisation's private library. Not charged if the file fails the checks.

Pass manufacturer part numbers (TPS54302, STM32F446RCT6) or LCSC numbers (C2837938), not values like 100nF or reference designators like R1. A datasheet nobody has asked for yet is read on first request (poll check_extraction_status); after that it is cached for everyone.

Prompts

Built-in prompts that walk the agent through common hardware tasks:

Prompt	What it does
`component-selection`	Select a component: define requirements, search candidates, compare specs, validate design fit.
`bom-review`	Review a bill of materials: look up each part, check stock and lifecycle, flag risks, suggest alternatives.
`datasheet-deep-dive`	Summarise a part and extract its pinout, electrical specs, absolute maximum ratings and application circuit.
`design-validation`	Check each component against its operating conditions and flag out-of-spec parameters.
`second-source`	Find second-source alternatives that match package, specs and availability.
`interface-check`	Check electrical and protocol compatibility between two ICs on a shared bus (SPI, I2C, UART): logic levels, timing, pull-ups, level shifters.
`firmware-kickstart`	Extract the register map, initialisation sequence and protocol details of a peripheral IC into a firmware integration guide.
`thermal-review`	Thermal and derating analysis: absolute maximum and recommended limits, junction temperature from RθJA, SOA derating, exposed-pad needs.

Resources

Resource	What it holds
`sheetsdata://workflow`	The recommended tool order for component selection and design validation.
`sheetsdata://tips/datasheet-pitfalls`	The eight most common datasheet reading mistakes: absolute maximum vs recommended, typical vs worst case, thermal derating, logic levels, I2C/SPI gotchas, decoupling, exposed pads, lifecycle.
`sheetsdata://tips/design-review-checklist`	A hardware design review checklist (power, signal interfaces, component selection, firmware), pointing at the tool or prompt for each check.

Pricing

Free to start. A new account gets $5 of credit, no card needed ($20 more when you add a card). Searching (search_parts, find_parts) is free.
Trial is pay as you go from a prepaid balance: 5 new datasheets a day (datasheets already read are unlimited), 30 requests a minute.
Pro is $39 a month minimum, with your calls counting toward it: no daily cap on new datasheets, higher rate limits and a private parts library.

Plans, limits and fees: sheetsdata.com/pricing.

Authentication

Use whichever your client supports; both bill the same organisation.

	OAuth (recommended)	API key
Best for	Interactive clients	CI, scripts, headless agents, clients without MCP OAuth
What you do	Add the URL, then sign in to SheetsData in the browser tab that opens	Create a key at sheetsdata.com/dashboard/keys and send `Authorization: Bearer`
Standards	OAuth 2.1 with PKCE, dynamic client registration (RFC 7591), discovery (RFC 8414, RFC 9728)	Bearer token (RFC 6750)
Revoke	Per app, from the dashboard	Delete the key

If a client asks how to register an OAuth client, choose automatic (dynamic) registration; SheetsData doesn't support client ID metadata documents yet.
