API, MCP & plugins

Choose a connection method. Check the package format for your app.

Set up with your AI assistant

Paste the prompt into Claude Code. It includes setup steps and a read-only connection check.

Choose what to connect

API key
A secret that identifies your account and permissions. Your app sends it with an API or MCP request.
REST API
HTTP endpoints for your application. Use curl or an HTTP client to start work and read results.
MCP server
A service that lists tools for an AI assistant. The assistant calls a tool with structured input and receives a result.
Plugin
An installable package for an app. It can include skills, MCP configuration and other components supported by that app.

LeadsAgent’s API and MCP server use the same task services. A plugin can point to that server and add workflow instructions. Installing a plugin still requires account access.

To connect now, use the MCP guide or REST quickstart. These guides describe direct connections. They do not imply that a LeadsAgent marketplace package is published.

LeadsAgent packages and branding

Published by LeadsAgent Team. These version 1.0.1 packages include the LeadsAgent brand asset and the metadata each format supports. They connect through OAuth. Extract a ZIP for local installation, or upload the OpenAI ZIP through its developer dashboard. Downloading a package does not update an existing connection or publish a directory listing.

Download ChatGPT and Codex ZIP · Development server ZIP

Portable plugin with logo, composer icon, listing links and team publisher. Public publisher display also requires the verified organization identity.

Download Codex compatibility ZIP · Development server ZIP

For clients expecting .codex-plugin/plugin.json. Current clients can use the portable OpenAI package.

Download Claude ZIP · Development server ZIP

Claude plugin manifest, directory icon and policy links, plus .mcp.json. The Claude chat connector has a separate registration.

Download Antigravity ZIP · Development server ZIP

Strict plugin manifest and mcp_config.json with serverUrl. Its documented manifest has no logo or publisher fields.

Download Gemini CLI enterprise / paid API ZIP · Development server ZIP

Compatibility extension with gemini-extension.json and httpUrl. Consumer users should choose Antigravity. Gemini Apps use the MCP URL directly.

Download Cursor ZIP · Development server ZIP

Cursor manifest with team author, homepage and bundled logo. Public listing requires a dedicated public plugin repository.

Download VS Code Agent Plugins ZIP · Development server ZIP

Portable Agent Plugins manifest and MCP configuration. A branded VS Code Marketplace extension requires a separate extension package.

For plain MCP connections, merge the file for your installed client into its existing configuration. These downloads use OAuth and contain no account secrets. Keep API keys in the client’s private credential store or supported environment references.

Development ZIPs connect to dev.leadsagent.io; use them for the active development server. Standard ZIPs use this deployment’s configured documentation origin, or leadsagent.io by default. Check that the selected server is deployed before installation. Development configurations and checksums

  • Claude configuration
  • Cursor configuration
  • VS Code / Copilot workspace configuration
  • VS Code editor compatibility configuration
  • Antigravity configuration
  • Gemini CLI enterprise configuration
  • OpenCode V1 configuration
  • OpenCode V2 configuration
  • Codex TOML configuration
  • Portable MCP configuration

Gemini Apps accept the MCP URL directly; Google documents no custom logo or publisher manifest. Custom Apps currently require an eligible US personal account, age 18+, English and Keep Activity enabled. n8n uses the MCP Client Tool; a branded community node is a separate npm package.

Package requirements by app

For plugin authors. Sources checked on 22 October 2026. Check the linked source before submitting a package.

Claude Code

.claude-plugin/plugin.json; skills/<name>/SKILL.md; .mcp.json when a connector is included.

Validate the plugin. Test a local install, sign-in and one read-only tool call. Add a marketplace entry when distributing through a marketplace.

Official package guide

Claude chat and Cowork

A hosted connector can use the remote MCP URL. A plugin can bundle the connector with skills.

Connector directory review requires tool titles, action annotations, tested authentication and review materials. Plugin submission is a separate flow.

Official package guide

ChatGPT and Codex

Root plugin.json, skills/ and mcp.json. OpenAI-specific fields go under extensions.com.openai. Older Codex packages can use .codex-plugin/plugin.json.

Validate the package and test on each target surface. Public remote MCP review needs a reachable HTTPS server and tested sign-in. The submission portal has no API-key header entry.

Official package guide

Cursor

Root plugin.json with mcp.json, or .cursor-plugin/plugin.json for the Cursor format.

Test locally. Submit a public Git repository with a valid manifest and README. Declare configuration variables required by the package.

Official package guide

Antigravity

Plugin folder with plugin.json at the root and mcp_config.json for the server. skills/, rules/ and agents/ are optional.

Install locally with agy plugin install <path>, then from GitHub with agy plugin install https://github.com/<owner>/<repo>. Gemini CLI extensions convert with agy plugin import gemini.

Official package guide

Gemini CLI enterprise / paid API

Root gemini-extension.json with name, version, description and mcpServers. Remote entries use httpUrl.

Use only with an eligible enterprise license or paid API key. Consumer Gemini CLI users moved to Antigravity. No extension logo, publisher or homepage field is documented.

Official package guide

VS Code and Copilot

User MCP configuration, or a VS Code extension that registers an MCP server definition provider.

An editor extension has its own package and review rules. Test editor setup separately from a Copilot harness configuration.

Official package guide

OpenCode

Remote MCP configuration, or an OpenCode JavaScript/TypeScript plugin. Plugin APIs differ between V1 and V2.

Use the format for the installed version. A Claude plugin manifest does not replace an OpenCode plugin module.

Official package guide

n8n

An MCP client in a workflow. A custom n8n node is a separate npm package.

Check that the installed MCP node supports Streamable HTTP. Save the key in n8n credentials. Test a draft before activating the workflow.

Official package guide

Before publishing

  1. Validate the package format for the target app. Include skills only when they add useful workflow instructions.
  2. Use a stable public HTTPS MCP URL. Keep account keys and provider secrets out of the package.
  3. Test sign-in, permissions, revocation and tool calls in that app. A successful curl request proves only that HTTP path.
  4. Provide the listing details, support contact, privacy information and review account required by the marketplace.

OpenAI submission requirements and Claude plugin requirements describe their separate review flows.
