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.
Demo
Agent: search_parts("buck converter 3A 28V")
→ TPS54302, LM2596, MP2315 with stock & pricing from JLCPCB, Mouser, DigiKey
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: find_alternative("TPS54302", constraints="in_stock,jlcpcb")
→ MP2315, TPS54331 ranked by package/spec match
The agent never sees a PDF. The engineer never uploads one.
Tools
| Tool | Description |
|---|---|
search_parts |
Search by part number or keyword across JLCPCB, Mouser, DigiKey. 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 — pricing, stock, parameters from all providers. |
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 with merged provider data. |
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. |
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. |
Resources
Data the server exposes for agent context:
| Resource | Description |
|---|---|
sheetsdata://providers |
List of active component data providers (JLCPCB, Mouser, DigiKey, Nexar) and their current status. |
sheetsdata://workflow |
Recommended tool workflow for component selection — search, evaluate, read datasheet, validate, compare. |

Recommended Workflow
1. search_parts → Find candidates by keyword or part number
2. get_part_details → Evaluate pricing, stock, parameters
3. read_datasheet → Get detailed specs (pinout, electrical, package)
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
