MemeStack

MemeStack MCP

Hosted Model Context Protocol server for MemeStack — a visual search engine for memes, infographics, charts, screenshots, and diagrams. Find images by meaning, by the OCR text printed inside them, or by visual similarity. AI-captioned, Lightning-ranked. Public, no auth, no signup — reads are free with daily quotas, generation is paid per call.

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. Every snippet below was checked against the client's own documentation on 2026-10-11; the current list, with a link to each client's docs, is on memestack.ai/mcp-server.

Claude Code

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

Or in a project .mcp.json — a remote server needs "type": "http":

{

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

Or as a plugin (adds a skill)

This repo is also a Claude Code plugin marketplace. The plugin installs the same server plus a find-image skill that tells Claude which tool answers which request and to keep the citation:

/plugin marketplace add Ed-Relight/memestack-mcp

/plugin install memestack@memestack

From a shell: claude plugin marketplace add Ed-Relight/memestack-mcp then claude plugin install memestack@memestack. If you also use the claude.ai connector, Claude Code lists the tools twice (one copy per server); either one is enough.

Claude (claude.ai and Claude Desktop)

Add MemeStack from the Connectors Directory, or as a custom connector: Customize → Connectors → + Add → Add custom connector with the directory endpoint https://mcp.memestack.ai/mcp/directory (see Chat apps below). Every plan can; a Free account can add one custom connector.

Claude Desktop's claude_desktop_config.json takes local servers only. To use the full /mcp endpoint there, bridge it with mcp-remote:

{

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

Cursor

One click opens Cursor's install prompt (Cursor's install links). This repo is also a Cursor plugin (.cursor-plugin/plugin.json + mcp.json, with the find-image skill). Or edit ~/.cursor/mcp.json (or per-project .cursor/mcp.json):

{

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

VS Code (GitHub Copilot)

One click: the Add to VS Code link on memestack.ai/mcp-server (a vscode:mcp/install link, which GitHub does not render). Or .mcp.json at the workspace root, or ~/.copilot/mcp-config.json for every workspace (the older .vscode/mcp.json with "servers" still loads, but VS Code now calls it deprecated):

{

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

Devin Desktop (formerly Windsurf)

devin mcp add memestack https://mcp.memestack.ai/mcp

Gemini CLI

gemini extensions install https://github.com/Ed-Relight/memestack-mcp

The extension manifest (gemini-extension.json) points Gemini CLI at the hosted endpoint over Streamable HTTP (httpUrl). Without the extension:

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

That writes .gemini/settings.json in the project; add --scope user for ~/.gemini/settings.json.

OpenAI Codex CLI

codex mcp add memestack --url https://mcp.memestack.ai/mcp

Or in ~/.codex/config.toml (shared with the ChatGPT desktop app and the Codex IDE extension):

[mcp_servers.memestack]

url = "https://mcp.memestack.ai/mcp"

Cline

In Cline's MCP settings (cline_mcp_settings.json), add the server with the camelCase streamableHttp type — without it Cline falls back to SSE and the endpoint answers 405:

{

"mcpServers": { "memestack": { "type": "streamableHttp", "url": "https://mcp.memestack.ai/mcp", "disabled": false, "autoApprove": [] } } }

The Remote Servers tab does the same (Transport "Streamable HTTP"), and so does the Cline CLI:

cline mcp add memestack https://mcp.memestack.ai/mcp --transport http --yes

Zed

In Zed's settings (zed: open settings file), or Settings → AI → MCP Servers → Add Remote Server:

{

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

Goose

goose configure → Add Extension → Remote Extension (Streamable HTTP), or in ~/.config/goose/config.yaml (Windows: %APPDATA%\Block\goose\config\config.yaml):

extensions:

memestack: type: streamable_http name: memestack enabled: true uri: "https://mcp.memestack.ai/mcp" headers: {} env_keys: [] envs: {} timeout: 300

LM Studio

LM Studio 0.3.17 or later: Program tab → Install → Edit mcp.json:

{

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

Continue

Create .continue/mcpServers/memestack.yaml (MCP tools work in agent mode):

name: MemeStack

version: 0.0.1 schema: v1 mcpServers:

• name: memestack type: streamable-http url: https://mcp.memestack.ai/mcp

Clients without remote MCP support

Bridge the endpoint with mcp-remote:

{

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

Raw JSON-RPC (any HTTP client)

curl -X POST https://mcp.memestack.ai/mcp \

-H "Content-Type: application/json" \ -H "Accept: application/json, text/event-stream" \ -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.

Chat apps (directory endpoint)

Chat apps get a second endpoint built for their connector directories:

https://mcp.memestack.ai/mcp/directory

It lists 18 read tools (every read tool except get_leaderboard, which still answers by name) — no paid tools, no payment offers, no daily quota — and its results never include images classified controversial (the include_controversial argument does not exist there; a by-id lookup of such an image answers "not found"). Resources and citations are the same as on /mcp; prompts/list there shows five prompts — every one but top_zapped, whose tool it does not list (it still answers prompts/get by name). Add it by URL as a custom connector (Streamable HTTP, no authentication). Tool calls are rate-limited per minute; over the limit a call answers "Too many requests from this client" — wait a minute and retry. In ChatGPT (and other MCP Apps hosts) image results appear as a carousel of image cards.

Where each app keeps the setting (checked 2026-10-11):

• Claude — see above.
• ChatGPT (web) — Plugins → + → Add custom MCP server → Server URL → Create as a plugin. Business and Enterprise/Edu; Pro can connect with read/fetch permissions in developer mode.
• Mistral Le Chat — Connectors → + Add Connector → Custom MCP Connector. Administrators (on Free, Pro and Student, the account owner).
• Perplexity — Account settings → Connectors → + Custom connector → Remote, transport Streamable HTTP. Pro, Max and Enterprise.
• Microsoft Copilot Studio — an agent's Tools page → Add a tool → New tool → Model Context Protocol, authentication None. Needs generative orchestration (not in the Copilot Studio for Teams plan).

What's exposed

• 22 tools, of which tools/list shows a core set by default — search_images, search_text_in_image, search_charts, find_meme_for_text, reverse_image_search, find_similar, get_image, get_receipts, cite_image, plus the two paid tools; every tool still answers by name. In all: 20 free reads (8 of them with a daily quota, then a fraction of a cent per call — see Pricing & payments), 2 always paid (generate_meme, submit_image) — 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). prompts/list shows a prompt only while every tool it uses is listed, so by default it shows three — search_memes, cite_this_meme, find_a_meme_for_vibe; the other three still answer prompts/get by name: docs/prompts.md
• 4 resources — attribution guide, tag taxonomy, recent uploads feed, and the memestack://top/{period} template (top zapped images): docs/resources.md

Tools at a glance

Discovery and search:

• search_images — semantic + keyword merged
• search_charts — charts/infographics with stored source metadata (dataset, citation, unit, regions, displayed period); not every chart — search_images has wider chart coverage. publisher_only: true (here and on search_images) keeps only charts imported from Our World in Data, USDA ERS, Eurostat or the EEA
• search_text_in_image — OCR-only search (find screenshots of specific quotes/text)
• find_meme_for_text — vibe-to-meme matcher for writing & social (only images tagged as memes, so it may come back empty; search_images covers every kind of image)
• 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_meme_variants
• get_receipts — where an image came from, the claims it makes, and publisher charts that measure the same thing (no verdict)

Honest search results (rolling out — the server labels results only while its honest-search switch is on): when results carry match, search_images, search_charts, search_text_in_image and find_meme_for_text label each one "strong" (MemeStack has evidence it matches your query) or "closest" (the nearest thing it has). Strong results come first; closest ones are capped and marked [closest match] in the text view. The first page starts with a note when nothing matched strongly, and has_more says whether another page exists (total counts strong matches only). Without labels there is no match, note or has_more: a page shorter than limit is the last. With labels, match_quality sums the search up: strong (it has a strong match), closest_only (every result is only the nearest guess — do not present one as the answer) or none.
