SheetsData MCP

Electronic component datasheets for AI agents — specs, pinouts, package data on demand. No PDFs required.

SheetsData is an MCP server that gives AI agents instant, structured access to electronic component data. One tool call returns the pinout. Another returns electrical specs. No PDFs. No uploads. No context window stuffing.

Beta — SheetsData is currently in public beta. APIs, pricing, and features may change. See Disclaimer below.

Demo

Agent: read_datasheet("TPS54302", section="pinout")
→ Pin table: BOOT(6), EN(5), FB(4), GND(1), SW(2), VIN(3)

Agent: check_design_fit("TPS54302", input_voltage=12, output_current=2)
→ PASS — all parameters within datasheet limits

Agent: "What's the maximum SPI clock frequency for the STM32G030?"
→ Uses read_datasheet to find electrical specs — returns 32 MHz

Agent: find_alternative("TPS54302", constraints="in_stock")
→ MP2315, TPS54331 ranked by package/spec match

The agent never sees a PDF. The engineer never uploads one.

Tools

Tool	Description
search_parts	Search for components by part number or keyword. Results merged by MPN with pricing and stock.
search_datasheets	Semantic search across all extracted datasheets. Natural language queries like "low-noise LDO with PSRR above 70dB".
prefetch_datasheets	Batch warm-up extraction for up to 20 parts. Fire-and-forget — reduces wait times.
check_extraction_status	Poll extraction progress after prefetch or read_datasheet.
get_part_details	Full component details — specs, parameters, pricing, and stock.
read_datasheet	Structured datasheet sections (summary, pinout, electrical, abs_max, package) or semantic search within a datasheet.
compare_parts	Compare 2–5 parts side by side on real datasheet specs.
check_design_fit	Validate operating conditions against datasheet limits. PASS/FAIL/WARNING per parameter.
find_alternative	Find alternative/substitute components by specs, package, or availability.
analyze_image	Vision AI analysis of datasheet images — graphs, package drawings, pin diagrams.
request_datasheet_upload	Request a signed URL to upload a datasheet PDF when we don't have one (datasheet_status = no_source or unsupported). Free — fee is only charged on confirm.
confirm_datasheet_upload	Confirm an upload: verifies SHA-256, validates PDF, checks MPN on first page, charges the upload fee, and queues extraction. Datasheets are private to your org.

Prompts

Built-in prompt templates that guide the agent through common hardware engineering tasks:

Prompt	Description
component-selection	Walk through selecting 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	Deep-dive into a specific part: summarize, extract pinout, electrical specs, absolute max ratings, and application circuit.
design-validation	Validate a design: check each component against operating conditions, flag out-of-spec parameters.
second-source	Find second-source alternatives for a part: match package, specs, and availability across providers.
interface-check	Check electrical and protocol compatibility between two ICs on a shared bus (SPI, I2C, UART). Verifies VOH/VOL vs VIH/VIL, flags level-shifter needs, extracts protocol config (SPI mode, I2C address, pull-up values).
firmware-kickstart	Extract register map, init sequence, and protocol details from a peripheral IC datasheet. Generates a firmware integration guide with register writes, transaction examples, and common pitfalls.
thermal-review	Thermal and derating analysis: compare operating conditions against abs max AND recommended limits, estimate junction temperature, check SOA derating curves, flag exposed-pad requirements.

Resources

Data the server exposes for agent context:

Resource	Description
sheetsdata://workflow	Recommended tool workflow for component selection — search, evaluate, read datasheet, validate, compare.
sheetsdata://tips/datasheet-pitfalls	The 8 most common datasheet interpretation mistakes — abs max confusion, typical vs worst-case, thermal derating, voltage levels, I2C/SPI gotchas, decoupling, exposed pads, lifecycle risks.
sheetsdata://tips/design-review-checklist	Hardware design review checklist covering power supply, signal interfaces, component selection, and firmware integration.

Authentication — pick OAuth, fall back to API key

SheetsData supports two auth paths. Use whichever works best for your client; both bill against the same org.

	OAuth 2.0	API key
Best for	Interactive MCP clients (Claude Desktop, Cursor, etc.)	CI, scripts, headless agents, or clients that don't speak MCP OAuth
What you do	Click Connect in your client → log in here → done	Generate a key in the dashboard, paste as a Bearer header
Setup	Just paste a URL	Paste a URL + a header
Discovery	Automatic via RFC 8414 / RFC 9728	n/a
Spec compliance	PKCE-mandatory, dynamic client registration (RFC 7591), refresh-token rotation	RFC 6750 Bearer
Revoke	Per-client, from /dashboard/keys	Delete the key

Recommended: OAuth. It's a single URL paste, no copy-pasting secrets, and you can yank a connected app from the dashboard at any time.

Quickest paths (one-click install)

Claude Desktop — download the .mcpb bundle from the latest GitHub release and drag-and-drop it into the Claude Desktop window. The install dialog will surface every tool the bundle provides before confirming. Leave the API key field blank to use OAuth (recommended) — Claude Desktop will open a browser tab on first use to authorize. No JSON editing.

Cursor or VS Code — single-click install pre-fills the config and prompts to authorize on first use.

For everything else, copy the snippet from the right section below.

Install

Claude Desktop

Easiest — drag-and-drop the bundled extension. Download the latest sheetsdata-x.y.z.mcpb from the Releases page and drop the file onto the Claude Desktop window. Claude shows the list of tools the bundle provides and installs it. Leave the API key field blank to use OAuth (recommended) — a browser tab opens on first use to authorize. No JSON editing, no npm install.

Or — add a remote connector via the UI. Open Claude Desktop → Settings → Connectors → Add custom connector at the bottom of the list.

Field	Value
Name	SheetsData
URL	https://mcp.sheetsdata.com/mcp

Click Add. Claude Desktop will open a browser tab to the SheetsData consent screen — pick the org to authorize, and you're done. Tools appear in Claude immediately.

Note: The claude_desktop_config.json file does not support the OAuth flow on Claude Desktop. The Connectors UI is the right path for OAuth — only fall back to the JSON config if you want to use an API key instead.

<details> <summary>Use an API key instead (via JSON config)</summary>

Open Claude Desktop → Settings → Developer → Edit Config, then add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "sheetsdata": {
      "url": "https://mcp.sheetsdata.com/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}

Restart Claude Desktop. Get a key from sheetsdata.com/dashboard/keys.

4. check_design_fit    → Validate against your operating conditions
5. find_alternative    → Find substitutes if needed
6. compare_parts       → Side-by-side comparison of finalists
