What changed 17

Every tool that appeared, vanished or quietly changed what it asks for. Recorded since 17 August 2026. No other catalogue keeps this.

6 Nov 2 tools changed the parameters they ask for find_parts, search
6 Nov 2 tool descriptions were rewritten find_parts, search
22 Oct a tool changed version
22 Sep a tool description was rewritten find_parts
22 Sep a tool changed the parameters it asks for find_parts
27 Aug 5 tool descriptions were rewritten find_parts, get_image, get_specs and 2 more
27 Aug a tool appeared get_segments
27 Aug a tool disappeared get
27 Aug a tool changed the parameters it asks for get_image
17 Aug a tool description was rewritten find_parts
and 1 more, back to 17 August 2026

Tools have disappeared from this server

A tool that vanishes takes a piece of your agent with it, and the change arrives silently. Watch this server and every such change lands in your inbox.

Available tools 7

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

compare
compare_parts
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).
image
get_image
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.
lookup
lookup
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).
parts
find_parts
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. Pass `cluster` (e.g. 'MCU', 'LDO') to search within one component class. `canonical` MUST be one of the exact (case-sensitive) names enumerated in this tool's inputSchema, also readable as the whatic://parametric/canonicals resource.
search
search
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. Other scopes: 'doc:<doc_id>', 'cluster:<name>', 'general'.
segments
get_segments
Expand opaque `ref` tokens (from search/lookup) into full datasheet segment content.
specs
get_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.

Whatic IC Datasheets — questions

Answers built from our own checks of this server.

What can Whatic IC Datasheets do?
It exposes 7 tools, read directly from the server on our last check. Among them: compare_parts, find_parts, get_image, get_segments, get_specs, lookup and 1 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Whatic IC Datasheets working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 188 ms. The bar chart above shows every period we have measured.
Did Whatic IC Datasheets ever remove tools?
Yes. get is no longer exposed — we recorded the date each one disappeared. A tool vanishing usually means a breaking change for anything that depended on it.
How do I connect Whatic IC Datasheets?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Whatic IC Datasheets need an API key?
No. Whatic IC Datasheets completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 7 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Whatic IC Datasheets?
It answers our handshake in 188 ms on average, which is faster than 74% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
