A remote MCP server for searching IC datasheets: find parts by parametric specs, read extracted specs, compare parts, and pull datasheet segments and figures.
What you can do
Find IC part numbers by parametric constraints, ranked by how many constraints each part meets and spread across device families, with per-constraint pass, fail or unknown results. Read canonical extracted specs (min, typ, max, unit, conditions) for known part numbers, optionally limited to chosen parameters. Compare parts by relative price tier, stock posture and library class from a distributor snapshot. Search the datasheet corpus for hit records with snippets and opaque refs, or use a one-shot lookup that returns full content of the most relevant segments grouped per part. Expand refs into full datasheet segment content and fetch figure images with captions and page metadata.
When to use it
Useful when selecting or shortlisting ICs against numeric requirements, checking a known part's parameters, or comparing candidate parts before design or purchasing decisions. Also handy when you need grounded answers or figures from real datasheet PDFs rather than general knowledge.
Requirements
Remote streamable HTTP endpoint at whatic.io; no packages, environment variables or headers declared, and no authentication declared. Network access to the endpoint is needed.
Before you install
Price and stock information is a relative ranking from a distributor snapshot, not a live quote, so do not treat it as current pricing or availability. Queries and part numbers are sent to the third-party service. Image fetching only works for refs that are image segments; other refs return an error record.
Enable the server for the chats that should use its tools.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Use with an agent
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/io.whatic%2Fdatasheets/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.
Shortlist IC part numbers by parametric spec constraints, ranked by how many constraints each part satisfies, then by headroom past those thresholds, and spread across device families. Each constraint is {canonical, op: gte|lte|eq|range, value, unit?}. Returns per-constraint pass/fail/unknown, plus `matched` (parts meeting EVERY constraint), `ranked` (all parts scored, partial matches included) and `returned` (parts in this response). `truncated` means some qualifying parts are not on this page. When `matched` is 0 every result is a partial match. `canonical` MUST be one of the exact (case-sensitive) names enumerated in this tool's inputSchema, also readable as the whatic://parametric/canonicals resource.
Parameterstop_kconstraintsrequired
get_specs
Read IC specs
Read canonical extracted specs (min/typ/max, unit, conditions) for known
IC part numbers from a pre-extracted parametric index — not from datasheet text.
This is the cheapest and most precise source for numeric parameters where it has
coverage. Optionally restrict to specific canonical parameter names.
A part absent from `results` (with a "No specs found" warning) means no index
coverage, not that the datasheet lacks the parameter — fall back to `lookup`
for that part.
Parameterscanonicalspart_numbersrequired
compare_parts
Compare IC cost and availability
Relative price tier, stock posture, and library class for a set of IC part
numbers (a ranking from a distributor snapshot, not a live quote).

search
Search datasheets
Search the datasheet corpus; returns hit records (metadata + snippet, each
with an opaque `ref`). Pass a ref list to `get_segments` for full content.
If you already know the part number(s), prefer `lookup` — it fuses this search
with `get_segments` in one call and groups full content per part. Use `search`
when the part is unknown, or to triage snippets before pulling full content.
For part-specific queries, pass scope='device:<MPN>' (e.g. scope='device:NE5532')
to restrict hits to that part and avoid cross-part contamination.
Parameterskqrequiredscope
lookup
Look up datasheet sections
One-shot spec/section retrieval: full content of the most relevant datasheet
segments for one or more parts (fuses search+get_segments). Already groups results per
part (via `parts`), so prefer `lookup` over `search` when you know the part(s).
Parameterspartsqueryrequired
get_segments
Expand datasheet refs
Expand opaque `ref` tokens (from search/lookup) into full datasheet segment
content.
Parametersrefsrequired
get_image
Fetch datasheet figures
Fetch datasheet figure images (PNG/JPEG) for opaque `ref` tokens obtained
from search/lookup/get_segments. Returns each image plus its caption/description/page
metadata. Only `type='image'` segments have image data; a ref that is not one comes
back as an error record whose `available_images` lists the document's figures nearest
that ref's page and section, closest first.
