match_hex_to_paint_colors
Convert any HEX color code into the closest official Sherwin-Williams, Benjamin Moore, and Behr paint colors using scientific CIEDE2000 (ΔE00) color difference, LRV, and undertone classification.
hex string · required
6-digit HEX color code (e.g. "#EAE6DF" or "7A8B8B")
brand string
Filter by paint brand or search across all 3 major brands (default: "all")
limit number
Maximum number of matches to return (1 to 15, default: 6)
A call is made on an account: it counts against an allowance and the publisher sees it, which is why this one asks who you are first.

What it does
Match HEX codes & find cross-brand paint equivalents across Sherwin-Williams, Benjamin Moore & Behr.
Quickstart
# 1 — sign in once: npx mcprush@latest login
# it asks for a key from mcprush.com/dashboard#access
# 2 — install
npx mcprush@latest add locatepic/paintcolormatcher-scientific-paint-color-hex-mcp
# 3 — ask your agent for something these tools do
# match_hex_to_paint_colors, find_cross_brand_paint_equivalent, calculate_ciede2000_swatch_distance and 5 more
Windows PowerShell says 'running scripts is disabled on this system'? Run Set-ExecutionPolicy -Scope CurrentUser RemoteSigned once, or type npx.cmd instead of npx (codex.cmd, gemini.cmd, grok.cmd likewise). PowerShell 7 needs neither.
PaintColorMatcher — Scientific Paint Color & HEX CIEDE2000 costs nothing on mcprush: there is no plan to choose here, no cap to set and nothing mcprush can bill you for.

Installation
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine — this server runs on the publisher’s own infrastructure behind our gateway, and what you install is the connection to it.
Claude Codedeclared by this listing
Claude Code has its own MCP command, and the key rides on it as a header — the gateway refuses a call that carries none. Claude Code reads MCPRUSH_KEY each time it connects, so the key stays out of its config: export your key from Access in your shell profile (macOS, Linux), or run setx MCPRUSH_KEY <your key> and open a new terminal (Windows). Or let npx mcprush@latest add locatepic/paintcolormatcher-scientific-paint-color-hex-mcp write the entry with the key for you; --scope user makes it available in every project.
claude mcp add --transport http --scope user paintcolormatcher-scientific-paint-color-hex-mcp https://mcprush.com/gw/paintcolormatcher-scientific-paint-color-hex-mcp/mcp --header 'Authorization: Bearer ${MCPRUSH_KEY}'Reconnect, or start a new session, and the tools appear in the model’s tool list.
Free to install on mcprush: no card. The gateway still answers a key, so you sign in once — which is also what gives you saved lists, release alerts and a budget cap.
What it writes
One config entry pointing at the gateway. The server itself runs on the publisher’s own infrastructure, so nothing from this listing executes on your machine.
What you approve
8 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.

ATool-list grade · score 96 / 100
Release 1.0.2 · scanned 11 Nov 2026
Graded from the tools this server lists, not from its source code.
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.

score = clamp(round(threatScore − E_cap − E_ver − E_cov), 0, 100). No model, no opinion, no network call at scoring time: the same methodology version against the same bytes always produces this number, and every line above is a field of the report rather than a summary of it.
What the scan could actually read
A grade is only as meaningful as its coverage, so the scanner publishes its own depth before it publishes its result.
The scan read each tool’s name, description, input schema and annotations exactly as the server listed them the last time it answered us; no code was reviewed. We ask the server again about once a month, and a list that changed is graded again.

Toxic-flow graph
The lethal trifecta, checked as a graph rather than as a checklist: untrusted input, a sensitive source and an external sink have to meet before there is a path worth worrying about.
The public result for this release does not print the flow graph, so there is nothing to show here. That is not the same as "no paths were found": what the scan did read is above, under coverage.

This is the first scan of this surface here, so there is nothing yet to compare it against.
Every result on this tab comes from one deterministic pass over the published package — offline, rule by rule, and auditable line by line above. Same methodology version, same bytes, same score.
