pangolinfo-mcp

Pangolinfo MCP server — 18 Amazon e-commerce & IP data tools for AI assistants via Model Context Protocol.

🔗 Official site: www.pangolinfo.com

Plug your favorite AI client (Claude Code, Cursor, Cline, Windsurf, Codex, Hermes, OpenClaw) into Pangolinfo's Amazon Scraper APIs and let the AI run real-time ad tracking, Sponsored Products analysis, VOC sentiment analysis, keyword monitoring, and competitor product audit — plus keyword research, listing analysis, review mining, niche discovery, category navigation, AI search lookups, keyword-trend checks, and WIPO trademark clearance — all from natural-language instructions.

⚠️ BREAKING CHANGE in 0.7.0 — pacer_search retired, merged into wipo_search

The standalone pacer_search tool was removed. US patent-litigation (PACER) lookups are now reached by passing enableLitigation=true to wipo_search — it finds the patent and joins the related US litigation cases in a single call. Prompts/scripts pinning pacer_search will get ToolNotFound; switch to wipo_search with enableLitigation.

Earlier breaking change (0.3.0 — tool renames)

Old name (≤ 0.2.x)	New name (0.3.0+)
google_ai_search	ai_search
google_trends	keyword_trends

Tool names changed to remove third-party brand references from the public MCP interface. Tool parameters, return shape, and pricing are unchanged.

Install

Recommended: one-line installer (covers 7 AI clients)

The Pangolinfo Installer detects your AI client, writes the right config files, and you're done. Pass --scope=mcp to install only this MCP server (skip the Skills package).

macOS / Linux

curl -fsSL https://pangolinfo.dev/install.sh | sh -s -- \  --agent=<your-agent> \  --scope=mcp \  --api-key=pgl_xxxxxxxxxxxx

Windows (PowerShell)

irm https://pangolinfo.dev/install.ps1 | iex; `  Install-Pangolinfo -Agent <your-agent> -Scope mcp -ApiKey pgl_xxxxxxxxxxxx

<your-agent> is one of: claude-code, cursor, cline, windsurf, codex, hermes, openclaw.

After the installer finishes, restart your AI client so it picks up the new mcpServers entry.

Manual install (just download one file)

The release artifact is a single self-contained server.mjs (~800 KB) — all dependencies are bundled in. No npm install needed.

# macOS / Linuxmkdir -p ~/.local/lib/pangolinfo-mcpcurl -fsSL https://github.com/pangolinfo/pangolinfo-mcp/releases/latest/download/server.mjs \  -o ~/.local/lib/pangolinfo-mcp/server.mjschmod +x ~/.local/lib/pangolinfo-mcp/server.mjs

# Windows (PowerShell)$dir = "$env:LOCALAPPDATA\pangolinfo-mcp"New-Item -ItemType Directory -Force -Path $dir | Out-Nullirm https://github.com/pangolinfo/pangolinfo-mcp/releases/latest/download/server.mjs `  -OutFile "$dir\server.mjs"

Then wire it into your AI client — see the per-client snippets below. Point args at the file you just downloaded.

Developers: to build from source, git clone this repo and run npm install && npm run build. The produced dist/server.mjs is identical to the release asset.

Get an API key

1. Sign up at https://tool.pangolinfo.com/#/en/system/loading?sourceTag=github_amz
2. Copy your pgl_xxxxxxxx key from the dashboard
3. Top up credits if needed (each Amazon Scraper API call costs 0.75 credits; pangolinfo_capabilities is free)

Manual configuration (per AI client)

Replace /abs/path/to/pangolinfo-mcp/dist/server.mjs with your real path, and pgl_xxxxxxxx with your key.

Claude Code (~/.claude/settings.json)

{  "mcpServers": {    "pangolinfo": {      "command": "node",      "args": ["/abs/path/to/pangolinfo-mcp/dist/server.mjs"],      "env": { "PANGOLINFO_API_KEY": "pgl_xxxxxxxx" }    }  }}

Prefer claude mcp add --scope user pangolinfo node /abs/path/to/dist/server.mjs — it writes the same entry without hand-editing JSON.

Cursor (~/.cursor/mcp.json)

{  "mcpServers": {    "pangolinfo": {      "command": "node",      "args": ["/abs/path/to/pangolinfo-mcp/dist/server.mjs"],      "env": { "PANGOLINFO_API_KEY": "pgl_xxxxxxxx" }    }  }}

Cline (VS Code extension)

Open Cline → MCP Servers → Edit settings JSON, then add:

{  "mcpServers": {    "pangolinfo": {      "command": "node",      "args": ["/abs/path/to/pangolinfo-mcp/dist/server.mjs"],      "env": { "PANGOLINFO_API_KEY": "pgl_xxxxxxxx" }    }  }}

The settings file lives at <vscode-user>/globalStorage/saoudrizwan.claude-dev/settings/cline_mcp_settings.json. If you're on the standalone Cline CLI, use ~/.cline/data/settings/cline_mcp_settings.json instead.

Windsurf (~/.codeium/windsurf/mcp_config.json)

{  "mcpServers": {    "pangolinfo": {      "command": "node",      "args": ["/abs/path/to/pangolinfo-mcp/dist/server.mjs"],      "env": { "PANGOLINFO_API_KEY": "pgl_xxxxxxxx" }    }  }}

Codex (~/.codex/config.toml)

[mcp_servers.pangolinfo]command = "node"args = ["/abs/path/to/pangolinfo-mcp/dist/server.mjs"]
[mcp_servers.pangolinfo.env]PANGOLINFO_API_KEY = "pgl_xxxxxxxx"

Hermes (~/.hermes/config.yaml)

mcp_servers:  pangolinfo:    command: node    args: ["/abs/path/to/pangolinfo-mcp/dist/server.mjs"]    env:      PANGOLINFO_API_KEY: pgl_xxxxxxxx

OpenClaw (~/.openclaw/openclaw.json)

{  "mcpServers": {    "pangolinfo": {      "command": "node",      "args": ["/abs/path/to/pangolinfo-mcp/dist/server.mjs"],      "env": { "PANGOLINFO_API_KEY": "pgl_xxxxxxxx" }    }  }}

Hosted (remote HTTP) — no local install

Don't want to install anything? Point your AI client at the hosted endpoint instead of a local server.mjs. This is the streamable HTTP transport (MCP spec), multi-tenant — you bring your own key on every request.

Passing your API key — two ways

1. Authorization header (recommended)

Authorization: Bearer pgl_xxxxxxxx

This is the preferred method: the key stays out of URLs, logs, and browser history. The Bearer scheme is matched case-insensitively (bearer, BEARER, Bearer all work) and extra whitespace is tolerated.

2. ?api_key= URL query (fallback)

https://mcp.pangolinfo.com/mcp?api_key=pgl_xxxxxxxx

Easiest for clients that only let you paste a URL. If your key contains URL-special characters, URL-encode it. The header (method 1) takes precedence if both are supplied.

Client config example (Claude Code / Cursor — "url"-style remote MCP)

{  "mcpServers": {    "pangolinfo": {      "url": "https://mcp.pangolinfo.com/mcp",      "headers": { "Authorization": "Bearer pgl_xxxxxxxx" }    }  }}

If your client can't set headers, fall back to the URL form: "url": "https://mcp.pangolinfo.com/mcp?api_key=pgl_xxxxxxxx".

Notes for custom / raw HTTP integrations

If you're calling the endpoint directly (not through a standard MCP client):

• POST your JSON-RPC body to /mcp.
• The MCP streamable transport normally requires the request to advertise both application/json and text/event-stream in its Accept header. This server backfills the missing media type for you, so a plain Accept: application/json, Accept: */*, or even a missing Accept header all work — you don't need to hand-craft it.
• A 401 means the key was not found in either the header or the query string — check that your client actually sent it (some libraries drop the Authorization header on cross-origin redirects).

Tools (20)

See MCP-TOOLS-MAP.md for the full coordination graph (which tools chain into which).

For competing offers, call scrape_url with parserName=amzFollowSeller and either an ASIN in content or an Amazon product URL. Each returned item includes soldBy, hasSoldByLink (linked seller name vs. plain text), and optional isFeatured for the featured offer.

Plus a free local call: pangolinfo_capabilities returns the full tool catalog, canonical workflows, and usage tips with no backend round-trip (0 credits). It is a self-introspection helper, not one of the 20 data tools.

Default marketplace is Amazon US (marketplaceId=ATVPDKIKX0DER, zip=90001). Override per call via tool arguments.

⏱️ Slow tools & your client's tool-call timeout

Two tools legitimately run long because they wait on live AI generation:

Most MCP clients enforce a per-tool-call timeout — often 60 seconds of silence — and abort the call if nothing comes back in time. When that happens the client reports a transport-level timeout/disconnect, and the agent mistakes it for "the tool is unavailable/broken." This is the usual reason search_amazon_alexa gets flagged as unavailable — it reliably crosses the silent 60s line.

Two things keep this from happening:

1. The server emits progress heartbeats. While a tool runs, the server sends a notifications/progress every 15s if your client included a progressToken in the call. Spec-compliant clients reset their idle timeout on each heartbeat, so the whole 60–90s render stays under the wire. Most modern MCP clients send a progressToken automatically — no action needed.

2. Raise the client timeout for clients that don't honor progress. If your client has no progressToken support or a hard cap, bump its MCP tool-call timeout to ≥120s before using search_amazon_alexa. Where to set it depends on the client (examples):

   • Claude Code / config-based clients: raise the MCP request/tool timeout in the client config.
   • Custom SDK clients: pass a larger timeout (and, ideally, a progressToken) in the callTool request options.

Also prefer exactly one prompt per search_amazon_alexa call — multiple prompts stack latency linearly and make the timeout far more likely.

Auth resolution order

The server resolves the API key with this priority:

1. CLI args: --api-key=pgl_xxx --api-base=... --scrape-base=...
2. Env vars: PANGOLINFO_API_KEY, PANGOLINFO_API_BASE, PANGOLINFO_SCRAPE_BASE
3. Config file at ~/.pangolinfo/config.json:
   json

   {  "api_key": "pgl_xxxxxxxxxxxx",  "api_base": "https://extapi.pangolinfo.com",  "scrape_base": "https://scrapeapi.pangolinfo.com"}

4. Missing key → startup failure with an actionable error.

CLI args win over env vars — convenient when you want per-server keys without polluting the global environment.

Internationalization

Tool descriptions and error hints are available in English and Chinese. The language is resolved in this order: --lang=zh|en → PANGOLINFO_LANG=zh|en → OS locale ($LANG starting with zh* → Chinese, otherwise English) → English when there is no locale signal at all. So a Chinese-locale machine gets Chinese automatically; everyone else gets English. Force a language explicitly:

"env": {  "PANGOLINFO_API_KEY": "pgl_xxxxxxxx",  "PANGOLINFO_LANG": "zh"}

Startup logs are always English (operator-facing); tool descriptions and error hint fields follow the resolved locale.

Verify your install

After restarting your AI client, ask it:

List all available pangolinfo MCP tools.

You should see 18 tools. Then try:

Use pangolinfo_capabilities with mode "summary".

This is a free local call — if it returns the tool catalog, your install is wired correctly. Next, run something paid like:

Search Amazon for "wireless mouse" and return the top 5 results.

Expected: ~0.75 credits deducted, ~300 KB of structured product data returned.

Adding a new tool

1. Create src/tools/<verb_noun>.ts exporting a Tool object — mirror search_amazon.ts.
2. Import it in src/tools/index.ts and append to the tools array.
3. Schema is zod; .describe() every field — the AI reads those.
4. Never call fetch directly — use ctx.client.post(...). Auth is already injected.
5. Throw PangolinfoError on failure; the HTTP client already throws this for non-2xx responses.

Security & Data Handling

We take operator and user safety seriously. By design, this MCP server:

• Brings your own key. Authentication is via your personal PANGOLINFO_API_KEY (issued at https://tool.pangolinfo.com/#/en/system/loading?sourceTag=github_amz). The key is read locally from your AI client's config or environment — it is never transmitted anywhere except to https://scrapeapi.pangolinfo.com (or https://mcp.pangolinfo.com for the hosted variant) over TLS 1.2+.
• No telemetry. This server does not phone home, does not collect usage analytics, and does not log your prompts. The only outbound traffic is the actual Amazon / Google / WIPO Scraper API calls you explicitly invoke through tools.
• No PII collection. No user account info, no email, no IP geolocation, and no prompt content is persisted by this server. Tool calls forward only the parameters you (or the AI agent) supplied.
• Read-only. Every tool is a strictly read-only data lookup. None of them can write to Amazon, place orders, post reviews, modify listings, or take any side-effecting action on third-party platforms.
• HTTPS-only transport. Both the stdio variant (local) and the hosted variant (https://mcp.pangolinfo.com/mcp) require HTTPS; HTTP requests are refused.
• Open source. The full source is in this repository under MIT license — anyone can audit what the server sends and where.
• Responsible use. Pangolinfo APIs aggregate public e-commerce data. You are responsible for using the returned data in compliance with the terms of service of the underlying platforms (Amazon, Google, etc.) and with applicable laws in your jurisdiction.
