    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.

    Description, as the server wrote it
    Paid (1 credit). Relight a finished interior visualization as day, evening or night, with lamps on or off, keeping the wall colour. Needs project_id and the color_key returned by visualize_room.

    • Nothing in its name or description says what it does, so it is counted as a write.

    What it can reach

    • untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
    Description, as the server wrote it
    Paid (Muro credits, needs a Muro API key). Repaint the walls in a photo of a room, facade or roof in 1 to 12 colours at once and return one image per colour. Give the photo as image_url (a public link) or image_base64. Give each colour as brand + name_or_code from the catalogue (e.g. "Farrow & Ball" + "Hague Blue") or as hex. Without a photo it paints Muro’s sample room (or facade, roof). Every colour comes with a shopping list: the closest real paints from several brands with ΔE and a verdict; pass country to put brands sold there first. RAL works as brand "RAL" + "9005" or just "RAL 9005". Waits up to about 45 seconds; if some colours are still being painted, it returns a job_id for get_visualization. Tell the user the cost before calling: 1 credit per colour in standard quality.

    Why it is in this group

    • The name "find_equivalents" says "find": a word for reading.
    Description, as the server wrote it
    Find the closest colours in OTHER brands to a given paint colour or hex value, e.g. "Behr equivalent of Farrow & Ball Hague Blue" or "which Benjamin Moore is closest to #D1CBC1". Give either brand + name_or_code, or hex. Distance is CIEDE2000 ΔE with a verdict: under 1 practically identical, under 2 very close, under 3.5 close, otherwise similar (nothing above ΔE 6 is returned). By default returns the single best match per brand, closest first; pass brands to restrict the search (with one brand you get several options from it). Always pass on the caveat that on-wall results depend on base, sheen and tinting.

    Why it is in this group

    • The name "get_paint_color" says "get": a word for reading.
    Description, as the server wrote it
    Look up one paint colour by brand and exact name or code, e.g. brand "Sherwin-Williams" + "SW 7029" or "Agreeable Gray"; brand "Farrow & Ball" + "Hague Blue" or "30". Case, spacing and accents are ignored. A brand sold in several markets (Dulux UK/PL, Sikkens NL/DE/IT, Beckers SE/PL) may return one match per market. If nothing matches exactly, returns close suggestions instead.

    Description, as the server wrote it
    List the paint brands in the database with their number of colours and a brand page url. With country (ISO code like "DE", "PL", "US", "GB" or a name like "Germany"), returns the brands sold there in order of local relevance.

    Why it is in this group

    • The name "search_paint_colors" says "search": a word for reading.
    Description, as the server wrote it
    Find paint colours by name or code across all brands, e.g. "Hague Blue", "SW 7029", "agreeable gray", "grün". Matching ignores case and accents ("sniezny" finds "Śnieżny") and every word may be a prefix. Optionally restrict to one brand. Returns name, brand, code, hex, LRV (light reflectance, 0 = black, 100 = white; lrv_source says whether it is the brand's own figure or our estimate from the hex), collection and the colour page url. To match a hex value or a colour from another brand, use find_equivalents instead.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Exfil surface

Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.

No private-data, untrusted-input, outbound path in this server alone: no tool is tagged outbound.

Reads private data1
Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write4
Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
Can send data out0
Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.

Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.

Claude Code permissions

Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. A read that can send data out (it takes a URL, say) asks first too. It assumes the server is installed as paint-colors. Review it before you use it.
