Bring Your AI

No-data MCP endpoint for Claude Code to Codex harness migration checks.

Bring Your AI MCP

Public metadata repository for the Bring Your AI remote MCP server.

Bring Your AI moves agent-harness context between tools, starting with Claude Code to Codex. The paid CLI runs locally on the user's machine. This hosted MCP endpoint is intentionally no-data: it only exposes preview, target-listing, and install-command tools. It does not accept harness files, generated memories, project files, API keys, GitHub handles, or file contents.

Endpoint

https://bringyour.ai/mcp

Transport: streamable HTTP.

Official registry name:

ai.bringyour/bringyour

Manifest:

https://bringyour.ai/.well-known/mcp.json

Tools

preview_move - Preview supported source and destination harness moves without receiving user files.
preview_build_setup - Preview first-setup generation options without receiving user files or work history.
install_local_cli - Return local CLI installation commands and verification steps.
list_targets - List supported source and destination agent harnesses.

Local CLI Flow

curl -fsSL https://bringyour.ai/install.sh | sh
bringyour preview --from claude-code --to codex
bringyour migrate --from claude-code --to codex --policy merge

Codex import validation pages:

Manual Codex-to-Codex sync:

bringyour sync export --root ~/.codex --out ./bya-codex-sync
bringyour sync plan --in ./bya-codex-sync --root ~/.codex
bringyour sync apply --in ./bya-codex-sync --root ~/.codex

Privacy Boundary

The remote MCP server must not receive private harness data. Actual migration and sync work happens through the local CLI or local MCP server. The hosted endpoint exists for discovery, preview, and install handoff.

Public Codex Artifacts

This repo also carries installable, no-secret public artifacts for auditing migrated Codex setups:

skills/bringyour-migration-auditor/SKILL.md - Codex skill for checking AGENTS.md/CLAUDE.md scope, hooks, MCP config, skills, secrets, and validation notes after a migration.
agents/harness-migration-auditor.toml - Codex subagent config for the same read-only audit path.
