Quick Install
Automated & IDE SetupCopy the AI prompt to install this server into Claude Code, Cursor, or another agent — or use 1-click editor setup below.
One-click editor setup isn’t available for this listing yet — we don’t have a confirmed install command, and we’d rather show nothing than point your editor at the wrong package or host. Follow the project’s own setup instructions, linked above.
Manual Client & Custom JSON ConfigExpand JSON â–¾
No confirmed setup config for this listing yet. We only publish a config block when the install details come from the project itself — its README, its docs, or a verified owner. We haven’t found those for Exactlane Preflight, and we’d rather show nothing than a guess you’d paste into your client. Follow the project’s own setup instructions for the current steps.
Documentation Overview
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.

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.
