Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Read-only lookups for image work: platform image sizes (official sources quoted), upload size limits, format choice, compression expectations and measured format-conversion results. Each answer links to a free in-browser Pixohub tool that performs the change.

get_platform_image_size — Platform image size
Advertised by the server during the last successful anonymous check.
Advertised read-only

Recommended image dimensions, aspect ratio, upload limits, cropping and safe zones for a social, video, marketplace or print placement (e.g. 'Instagram story', 'YouTube thumbnail', 'Etsy listing', 'LinkedIn banner'). Returns official-source quotes with check dates where available.

find_upload_size_limit — Upload size limit
Advertised by the server during the last successful anonymous check.
Advertised read-only

Looks up official file-size and dimension limits for photo/document uploads: email attachments, government exam and visa forms, avatars, marketplaces (e.g. 'Gmail attachment', 'SSC photo', 'Discord avatar', 'US visa photo'). Returns the quoted rule, its source and a compress-to-size tool.

compression_advice — Compression advice
Advertised by the server during the last successful anonymous check.
Advertised read-only

Given a target file size (KB) and optionally the image's current size and pixel dimensions, says what to expect when compressing to that size — quality, how much resolution is usually kept — based on Pixohub's measured tests on 44 photos, and links the matching compress-to-size tool.

conversion_test_result — Measured conversion result
Advertised by the server during the last successful anonymous check.
Advertised read-only

Returns Pixohub's measured result for converting between two image formats (e.g. png → webp, heic → jpg): output size change, fidelity (SSIM/PSNR), and whether transparency and EXIF survived.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http pixohub-mcp https://mcp.pixohub.com/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add pixohub-mcp --url https://mcp.pixohub.com/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable pixohub-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "pixohub-mcp": {
      "url": "https://mcp.pixohub.com/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
Cline configuration
{
  "mcpServers": {
    "pixohub-mcp": {

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start pixohub-mcp and inspect its tools.
VS Code configuration
{
  "servers": {
    "pixohub-mcp": {
      "type": "http",
      "url": "https://mcp.pixohub.com/mcp"

  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http pixohub-mcp https://mcp.pixohub.com/mcp

Claude Desktop

Open Claude Settings > Connectors > Add custom connector, enter this server URL and enable it for the conversation. This is a manual remote-connector handoff, not a desktop JSON configuration.

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
Windsurf configuration
{
  "mcpServers": {
    "pixohub-mcp": {
      "serverUrl": "https://mcp.pixohub.com/mcp"
