Limelink MCP Server

@limelink/mcp

한국어 · Documentation · Capability reference

A Model Context Protocol (MCP) server for LimeLink dynamic link management. Create, look up, and manage dynamic links directly from Claude Code, Claude Desktop, or any MCP-compatible client.

No API key required to get started! Documentation and SDK setup guides work without any configuration. Just connect and start exploring LimeLink features with your AI assistant.

Features

• Documentation Resources — Access LimeLink docs (15 pages + index) directly from your AI assistant — no API key needed
• 5 Tools — Discover profiles and Projects, create dynamic links, and look up links (API tools require a configured profile)
• In-memory Caching — 1-hour TTL cache for documentation fetches

Runtime

• Node.js 18 or later
• stdio transport only; Remote MCP/HTTP transport is not supported
• npm package: @limelink/mcp; global executable: limelink-mcp
• stdout is reserved for the MCP protocol; diagnostics and wrapper logs must use stderr

See installation and configuration and network behavior for the complete operational contract.

What works without an API key?

Quick Start

Without API Key (Documentation & Guides)

No API key needed. Connect and start exploring LimeLink documentation and setup guides immediately:

{
  "mcpServers": {
    "limelink": {
      "command": "npx",
      "args": ["-y", "@limelink/mcp"]
    }
  }
}

Try asking your AI assistant:

• "Read the LimeLink getting-started docs"
• "How do I set up deep linking for iOS?"
• "Show me the LimeLink SDK integration guide"

With Organization Profiles (Full Features)

Create the version 1 profile file shown below and pass its absolute path:

{
  "mcpServers": {
    "limelink": {
      "command": "npx",
      "args": ["-y", "@limelink/mcp"],
      "env": {
        "LIMELINK_PROFILES_FILE": "/absolute/path/to/limelink-profiles.json"
      }
    }
  }
}

Usage with Global Install

npm install -g @limelink/mcp

{
  "mcpServers": {
    "limelink": {
      "command": "limelink-mcp",
      "env": {
        "LIMELINK_PROFILES_FILE": "/absolute/path/to/limelink-profiles.json"
      }
    }
  }
}

Configuration

Claude Code

The easiest way to add the MCP server is using the claude mcp add command:

# Without API key (docs & guides only)
claude mcp add --scope user --transport stdio limelink -- npx -y @limelink/mcp

# With API key (full features)
claude mcp add --scope user --transport stdio limelink \
  --env LIMELINK_PROFILES_FILE=/absolute/path/to/limelink-profiles.json \
  -- npx -y @limelink/mcp

Scope options:

• --scope user — Available in all projects
• --scope project — Saved to .mcp.json (shareable with team via Git)

Claude Desktop & other MCP clients

Add the JSON config to your client's config file:

Profile file

{"version":1,"defaultProfile":"work","profiles":{"work":{"apiKey":"your_api_key","organizationLabel":"Work","projects":{"marketing":"11111111-1111-4111-8111-111111111111"}}}}

Environment Variables

LIMELINK_API_KEY and LIMELINK_PROJECT_ID are ignored. When no credential profile is configured, API-backed tools direct the agent to Organizations to issue an Organization API key and configure the profile file. Project-backed tools accept a Project UUID directly. A profile's optional projects map is a recommended convenience for repeatedly used Projects, not a prerequisite; add aliases after list-projects discovery if useful. Profiles initialize lazily through credential introspection on their first API-backed call. Profile-file changes, including alias additions, require an MCP server restart.

You can get your API key from the LimeLink Dashboard. Without an API key, documentation resources and SDK setup guides are fully available.

Tools

list-profiles

Lists configured aliases, Organization labels, default status, and current initialization status without contacting the API. Already initialized profiles include scopes. API key values remain secret and are never returned. Organization, Project, Custom Domain and credential identifiers and key prefixes are non-secret identifiers and may appear in API-backed tool responses when useful.

list-projects

Lists Projects in the Organization discovered from the selected profile's credential. Accepts optional profile; the credential requires projects:read.

list-custom-domains

Lists Custom Domains for required project (alias or UUID). Accepts optional profile; the credential requires domains:read.

create-link

Create a V2 Core Link with platform-specific deep linking, Custom Domain selection, social previews, and UTM tracking.

Parameters:

Example usage in Claude:

"Create a dynamic link for https://example.com/product/123 with suffix 'product-123' and enable analytics"

get-link-by-suffix

Look up a dynamic link by its suffix.

get-link-by-url

Resolve a Link through the V2 API using its full URL. The backend determines whether the URL belongs to a Free default namespace, Project hostname, or active Custom Domain. No Project selector or local suffix parsing is required.

The URL must be absolute HTTPS with exactly one /{suffix} path segment and no query, fragment, explicit port, or credentials.

Resources

limelink://docs/index

Returns the full LimeLink documentation index (llms.txt).

limelink://docs/{slug}

Returns individual documentation pages. Available slugs:

introduction, getting-started, project, application, dynamic-link, create-link, link-detail, link-management, appearance, sdk-integration, ios-sdk, android-sdk, api-integration, advanced, llm-agent

Example usage in Claude:

"Read the LimeLink API integration docs"

Claude will access limelink://docs/api-integration
