Verdict: choose Retro Diffusion Pixel Art for security work over a hosted endpoint; choose Shodan for security as a local process. You can also run both side by side in one mcpServers block.

Retro Diffusion Pixel Art tools 33

  • authenticateAuthenticate this MCP session with a RetroDiffusion public API key.
  • logoutClear the authenticated RetroDiffusion API key for this MCP session.
  • create_user_styleCreate a user style from the public RD Pro template using /v2/styles. Use `style_reference_images` and `style_reference_caption` for style-level references. These are baked into the custom style and are not the same as per-inference `reference_images`.
  • update_user_styleUpdate a public RD Pro user style using /v2/styles/{style_id}. Use `style_reference_images` and `style_reference_caption` for style-level references. These are baked into the custom style and are not the same as per-inference `reference_images`.
  • delete_user_styleDelete a user style using /v2/styles/{style_id}. style_id can be either internal id or prompt_style/public_id.
  • list_available_stylesList publicly available styles from /v2/styles/selector. Use this to discover valid prompt_style values plus style metadata such as require_input_image and supports_reference_images.
  • list_available_modelsReturn unique public model identifiers available in /v2/styles/selector.
  • get_style_usageExplain how to use a public prompt_style from the RetroDiffusion API. Use this before create_inference if you are unsure whether a style expects `input_image`, supports per-inference `reference_images`, or whether you meant style-level `style_reference_images`.
  • get_balanceGet credits/balance using the public /v2/inferences/credits endpoint.
  • estimate_inference_costEstimate generation cost using the public /v2/inferences endpoint with check_cost=true. Use `input_image` for the main source image, `reference_images` for extra per-inference guidance, and `style_reference_images` only on create_user_style/update_user_style.
  • create_inferenceGenerate images using the public /v2/inferences endpoint. For the highest quality prefer RD Pro styles (rd_pro__*); they support reference_images for character/style consistency, and most go as small as 12x12 px (check list_available_styles for each style's limits) — a small target size is never a reason to switch to a cheaper model family. Style ids are opaque strings with no uniform format (some RD Fast styles appear as "default:rd_flux"); take them verbatim from the catalog and never infer capabilities from an id's prefix. For animation styles prefer start_inference_job + get_inference_job instead — animations are long-running, and a failed animation is worth one retry with identical parameters (failures auto-refund). Field-tested workflow rules: N distinct items = N individually usable images (separate calls or num_images=N), never one sheet/grid image unless a sheet IS the deliverable. Variants of ONE image (seasons, day/night, palettes) = generate the base once, then derive each variant with the image_edit tool ("... keep the exact same composition") — independent generations of the "same" scene come out unrelated. Converting an existing image INTO pixel art is rd_pro__pixelate with input_image (16-256 px output, batch<=16); reference_images-based generation re-imagines rather than converts. To animate an image you already have, use rd_advanced_animation__* with input_image (fixed-format rd_animation__* styles generate their own subject from the prompt instead). To get the other directional views of a sprite you already have, use rd_advanced_animation__rotate with input_image (same 8-direction layout as rd_animation__8_dir_rotation). Use `input_image` for the main source image, `reference_images` for extra per-inference guidance, and `style_reference_images` only on create_user_style/update_user_style. The response excludes raw base64 image payloads to keep MCP outputs compact.
  • list_edit_toolsList the enabled canvas edit tools from /v2/edit/tools with their fields, costs, and limits. Edit tools are the recommended way to post-process generated pixel art: background removal, palette conversion, color reduction, pixel correction, rotation, inpainting, outpainting, seam tiling, and prompt-driven edits.

  • ip_lookupRetrieve comprehensive information about an IP address, including geolocation, operating system, open ports, running services (product, version, CPE), known vulnerabilities (CVEs), SSL certificates, hostnames, and cloud provider details if available. Returns service banners and HTTP server information when present. Optional history returns historical banners; minify omits banners.
  • shodan_searchSearch Shodan's database of internet-connected devices. Returns detailed information about matching devices including services, vulnerabilities, and geographic distribution. Supports advanced search filters and returns facet statistics (default: by country). Costs 1 query credit when the query uses filters, plus 1 per page beyond the first. Use shodan_count (free) to get totals and facets without results.
  • cve_lookupQuery detailed vulnerability information from Shodan's CVEDB. Returns comprehensive CVE details including CVSS scores (v4/v3/v2), EPSS probability and ranking, KEV status, proposed mitigations, ransomware associations, and affected products (CPEs).
  • dns_lookupResolve domain names to IP addresses using Shodan's DNS service. Supports batch resolution of multiple hostnames in a single query. Returns IP addresses mapped to their corresponding hostnames.
  • reverse_dns_lookupPerform reverse DNS lookups to find hostnames associated with IP addresses. Supports batch lookups of multiple IP addresses in a single query. Returns all known hostnames for each IP address, with clear indication when no hostnames are found.
  • cpe_lookupSearch for Common Platform Enumeration (CPE) entries by product name in Shodan's CVEDB. Supports pagination and can return either full CPE details or just the total count. Useful for identifying specific versions and configurations of software and hardware.
  • cves_by_productSearch for vulnerabilities affecting specific products or CPEs. Supports filtering by KEV status, sorting by EPSS score, date ranges, and pagination. Can search by product name or CPE 2.3 identifier. Returns detailed vulnerability information including severity scores and impact assessments.
  • shodan_countGet the total number of Shodan results for a query, with optional facet breakdowns (e.g. by country, org, port). Free: does not consume query credits. Use search_filters to list valid filters and facets.
  • domain_infoGet subdomains and DNS records for a domain from Shodan. Costs 1 query credit per lookup.
  • api_infoShow the Shodan API plan, remaining query and scan credits, monitored IPs, and usage limits for the configured API key. Free: does not consume credits.
  • search_filtersList the search filters and facets Shodan supports. Use this to build valid shodan_search and shodan_count queries and facets. Free: does not consume credits.

Frequently asked questions

Retro Diffusion Pixel Art is categorized under Security and uses a remote HTTP/SSE transport. Shodan belongs to Security and uses a local stdio subprocess. Pick Retro Diffusion Pixel Art for security work and Shodan for security.

Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.

Retro Diffusion Pixel Art has no declared pricing — check the project's own site. Shodan has no declared pricing — check the project's own site. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.

Yes. MCP clients support multiple servers: add retro-diffusion-pixel-art and shodan-2 as separate keys in the same mcpServers object, and your assistant will call tools from either one.

On AllMCPs, Retro Diffusion Pixel Art has a quality signal of 57/100 (Good) with 0 views, 0 installs and 7 GitHub stars. Shodan has 68/100 (Great) with 1 views, 0 installs and 179 GitHub stars.
