Install

Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

Remote (streamable-http)
Claude Code 
claude mcp add --transport http openlayer 'https://mcp.openlayer.com/mcp'
JSON configuration (Claude Desktop, Cursor, VS Code) 
{
    "mcpServers": {
        "openlayer": {
            "type": "http",
            "url": "https://mcp.openlayer.com/mcp"
        }
    }

Openlayer Skills

Agent Skills that teach AI coding assistants (Claude Code, Cursor, GitHub Copilot, etc.) how to integrate apps with Openlayer — the AI evaluation and observability platform.

Coding agents produce significantly better results with the skill installed, because they are conditioned to follow Openlayer's current best practices instead of guessing from memory (outdated SDK calls, wrong env vars, invented test configs).

Skills

SkillDescription
openlayerMain skill. Instrument code with tracing (monitoring), set up offline openlayer.json + tests.json evals (development), create tests/guardrails, gate CI/CD, run the MCP fix-loop, and access data and docs.

Installation

Claude Code plugin
claude plugin marketplace add openlayer-ai/openlayer-skills
claude plugin install openlayer@openlayer
Cursor plugin
/add-plugin openlayer
GitHub Copilot

GitHub Copilot reads .github/plugin/plugin.json and the same skills and .mcp.json as Claude Code.

In VS Code, add the marketplace to your settings.json, then install Openlayer from the Extensions view (search @agentPlugins):

{
  "chat.plugins.marketplaces": ["openlayer-ai/openlayer-skills"]
}

In the Copilot CLI:

copilot plugin marketplace add openlayer-ai/openlayer-skills
copilot plugin install openlayer@openlayer
Other agents

Codex, Gemini CLI, Windsurf, opencode, and dozens more install through the skills CLI:

npx skills add openlayer-ai/openlayer-skills --skill "openlayer"

For claude.ai, Copilot's cloud coding agent and code review, a manual symlink, or anything else, see the installation guide — it is the source of truth and stays current as these tools change.

Prerequisites

An Openlayer account and an API key:

export OPENLAYER_API_KEY=...
# self-hosted / local only:
export OPENLAYER_BASE_URL=https://api.openlayer.com/v1

Find your API key in the Openlayer app under Workspace settings → API keys (see https://docs.openlayer.com/workspace-and-projects/find-your-api-key).

Usage

Once installed, the agent uses the skill automatically when relevant — for example:

  • Adding Openlayer tracing/monitoring to an LLM or agent app
  • Setting up offline evals (openlayer.json + tests.json) and pushing commits
  • Creating tests from the catalog and configuring guardrails
  • Gating CI/CD on eval results
  • Debugging failing tests via the Openlayer MCP fix-loop
  • Querying projects, pipelines, test results, or looking up Openlayer docs

MCP server

The plugin also connects your agent to the hosted Openlayer MCP server at https://mcp.openlayer.com/mcp. The first time a tool is used, you sign in to Openlayer with OAuth and pick a workspace. The agent can then read projects, data sources, traces, tests, results, and governance rules in that workspace, and create or update them when you ask. Write and delete tools ask for confirmation.

Tool calls go only to Openlayer's API. Nothing is sent anywhere else. See the privacy policy. Self hosted deployments should point the server at their own URL, as the MCP docs describe.

Frequently asked questions

What is Openlayer?

Inspect AI projects, traces, tests, and governance rules in Openlayer, and debug failing evals.

How do I install Openlayer?

It runs as a remote server. In Claude Code: claude mcp add --transport http openlayer 'https://mcp.openlayer.com/mcp'. For other clients, paste the JSON configuration from this page into their MCP settings.

Does Openlayer need an API key?

Its registry entry lists no required key or secret. Some features may still need an account with the service it connects to.

Is Openlayer open source?

Yes. Its code is on GitHub under the Apache-2.0 license.

Who maintains Openlayer?

It is published by openlayer-ai. AI.tn lists it but does not maintain or endorse it.

From the official MCP Registry. Listing is not an endorsement: review a server's code and permissions before giving it access to your data.
