MemeStack MCP

Hosted Model Context Protocol server for MemeStack — a searchable gallery of AI-tagged memes, infographics, charts, screenshots, and visual explainers, ranked by Lightning zaps. Free, public, no auth, no signup.

https://mcp.memestack.ai/mcp

Every list response returns citation blocks (markdown / HTML / plain) ready to paste with attribution. Image bytes are served from https://api.memestack.ai/v1/images/{id}/{thumbnail|canonical|social-card} — directly embeddable.

Install

This is a hosted server. No clone, no build, no local environment. Point any MCP-aware client at the endpoint.

Claude Code

claude mcp add --transport http memestack https://mcp.memestack.ai/mcp

Claude Desktop

Edit claude_desktop_config.json (%APPDATA%\Claude\ on Windows, ~/Library/Application Support/Claude/ on macOS):

{
  "mcpServers": {
    "memestack": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://mcp.memestack.ai/mcp"]
    }
  }
}

Recent Claude Desktop versions support direct HTTP MCP servers — if yours does, you can drop the mcp-remote wrapper:

{
  "mcpServers": {
    "memestack": { "url": "https://mcp.memestack.ai/mcp" }
  }
}

Cursor

Edit ~/.cursor/mcp.json (or per-project .cursor/mcp.json):

{
  "mcpServers": {
    "memestack": { "url": "https://mcp.memestack.ai/mcp" }
  }
}

Continue.dev (VS Code / JetBrains)

In ~/.continue/config.json, add under mcpServers:

"memestack": { "url": "https://mcp.memestack.ai/mcp" }

Raw JSON-RPC (any HTTP client)

curl -X POST https://mcp.memestack.ai/mcp \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'

Same endpoint for initialize, tools/call, prompts/list, prompts/get, resources/list, resources/read. Protocol version: 2025-06-18.

What's exposed

• 18 free tools + 1 enterprise stub — full catalog: docs/tools.md

• 6 prompts — pre-baked workflows (topic search, top zapped, cite a meme, find a meme for a vibe, research meme evolution, trending): docs/prompts.md

• 3 resources — attribution guide, tag taxonomy, recent uploads feed: docs/resources.md

Tools at a glance

Discovery and search:

• search_images — semantic + keyword merged

• search_text_in_image — OCR-only search (find screenshots of specific quotes/text)

• find_meme_for_text — vibe-to-meme matcher for writing & social

• reverse_image_search — phash-based "find this image" (accepts HTTPS or data: URLs)

• find_similar / find_related — neighbors of a known image (visual phash / semantic embedding)

• browse_images, browse_by_tag, browse_by_category, list_categories

• popular_tags, tag_autocomplete, get_tag_profile

• get_image, get_user_profile, get_leaderboard, get_mutation_group

Attribution:

• cite_image — canonical markdown/HTML/plain attribution blocks for one or many image IDs

Enterprise stub:

• submit_image — reserved for a future agent-tier monetization spec; currently returns a polite redirect

Citations are baked in

Every list response includes a citations_combined block in three formats (markdown / HTML / plain) for the full set, plus a per-image citation on every individual image. Per-source rules differ — OWID images carry CC-BY 4.0 attribution to Our World in Data; Imgflip templates carry Imgflip attribution; direct uploads carry the uploader's display name and the MemeStack page URL.

Read memestack://attribution-guide once per session for the license model and per-source rules. See docs/resources.md.

Tier model

Currently everything except submit_image is tier: free with no per-call cost. IP-level rate limits apply for abuse protection. reverse_image_search is rate-limited to 10/min/IP since each call hashes the input image.

submit_image is tier: enterprise and reserved for a future agent-tier monetization flow — calling it returns a discoverable error pointing at memestack.ai/mcp/agent-tier.

Discovery surface

How MemeStack exposes itself to AI agents, beyond MCP:

Source

The MCP server runs on Cloudflare Workers and proxies the public MemeStack REST API (api.memestack.ai). The server's source is part of the larger MemeStack codebase, which is not publicly mirrored at this time. This repository hosts the public-facing docs, install snippets, and tool catalog so directory submissions and integrators can link to a stable, browsable surface.

If you want to fork the protocol behavior and self-host a similar gallery, the REST API is documented and a sufficient backend for any MCP-style wrapper.

License

MIT — covers the snippets and docs in this repo. The hosted MemeStack service is governed separately by memestack.ai/terms. Image content carries per-source licenses, surfaced in each image's citation block.
