Common questions

Is Exactlane Preflight safe?

It passed 4 of 5 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed 33 days ago, and the latest version (0.1.0) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT Business and above.

What can I use instead?

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.

Live machine contract

Canonical public discovery origin:

Service root: https://exactlane.dev/
Manifest: https://exactlane.dev/.well-known/exactlane.json
OpenAPI: https://exactlane.dev/openapi.json
Agent discovery text: https://exactlane.dev/llms.txt
Sitemap: https://exactlane.dev/sitemap.xml
Remote MCP: https://exactlane.dev/mcp

Snapshots of these documents are mirrored in discovery/ so they can be read and diffed here. The live endpoints above are authoritative; the snapshots are regenerated from the deployed commit.

Notes

MCP tool schemas that are valid on one side and unusable on the other: sourced cases where hosts or clients silently drop or reject tool schemas, and what Preflight can and cannot check about them.
