How to install Exactlane Preflight in Claude CodeAnthropic's agentic CLI

Add the server

bash

claude mcp add --transport http preflight https://exactlane.dev/mcp

Verify it's connected
bash
```
claude mcp list
```
Sharing it with your team?
Add `--scope project` to write it to .mcp.json in the repository root, which you can commit (with the secrets left as environment variables).
Use it in a session
Ask Claude to use the tools this server exposes (e.g. check_mcp_capability). It discovers them automatically.

How to install Exactlane Preflight in Claude DesktopDesktop app (MCP config)

Open your MCP config
macOS: ~/Library/Application Support/Claude/claude_desktop_config.json · Windows: %APPDATA%\Claude\claude_desktop_config.json

Add this server

json

{
  "mcpServers": {
    "preflight": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://exactlane.dev/mcp"
      ]
    }
  }
}

Why the wrapper?
This is a remote (HTTP) server and Claude Desktop only launches local processes, so mcp-remote proxies the connection. It will open a browser window if the server needs OAuth.
Restart Claude Desktop
The tools appear under the 🔌 menu once the app reloads.

How to install Exactlane Preflight in CursorAI-first code editor

Create / edit .cursor/mcp.json in your project

json

{
  "mcpServers": {
    "preflight": {
      "url": "https://exactlane.dev/mcp"
    }

Enable it
Cursor Settings → MCP → toggle the server on. Tools become available to the Composer/Agent.

How to install Exactlane Preflight in Codex CLIOpenAI coding agent

Add to ~/.codex/config.toml

toml

[mcp_servers.preflight]
command = "npx"
args = ["-y", "mcp-remote", "https://exactlane.dev/mcp"]

Why the wrapper?
Codex runs MCP servers as local processes, so mcp-remote bridges this HTTP endpoint to stdio.
Run Codex
Codex loads MCP servers from config.toml on startup and exposes their tools to the agent.

Reload
Windsurf → Cascade → refresh MCP servers. Cascade can now call the tools.

What tools does Exactlane Preflight expose? (1)

Read from the live server. Click any tool for its input schema.

check_mcp_capabilityBefore relying on an MCP capability, answer one question about it: does this exact revision satisfy the requirements your workflow declares? Call it for new work, after a dependency changes, after your own requirements change, or when an integration has already failed and you need to know whether the capability is why (the public triggers are NEW_WORK, DEPENDENCY_CHANGE, REQUIREMENTS_CHANGE, INTEG

What the code can do

This is a remote server — nothing is installed or run on your machine, so there is no local code to analyze. What it can reach is described above: your requests go to the provider's host.

Before you install

Signals gathered from the source repo and package registry — not a safety verdict.

What it can reach

Third-party hosted service — Your requests and any data in them are sent to exactlane.dev.
No local execution — Nothing is installed or run on your machine.

Exactlane Preflight

The check before the call.

Caller-specific static compatibility evidence for autonomous agents evaluating an MCP capability before relying on it.

Exactlane helps an agent answer: *does this exact declared MCP capability fit my bounded workflow requirements?* before integration.

Problem it addresses

Before an autonomous agent depends on an external MCP capability, it often needs a pre-integration compatibility check:

compare a caller-provided capability snapshot to caller-specific requirements;
obtain static compatibility evidence (not live probing);
keep the operational decision with the caller.

Exactlane Preflight is a Phase 0A public service for that workflow.

Use when

An agent has a caller-provided MCP capability snapshot and needs to determine whether that exact declared capability fits its own bounded workflow requirements.

Does not prove

live availability
full MCP conformance
business-result correctness
provider trust
security certification
payment success

Exactlane Preflight is primarily a REST evidence service with a thin remote MCP adapter at /mcp. It is not an A2A agent, marketplace, or certification authority.
