Install Om MCP in Codex

Add the hosted Om MCP to Codex and authenticate with Codex OAuth login.

Codex supports remote HTTP MCP servers and stores those entries in ~/.codex/config.toml. For Om MCP, the supported hosted setup is to point Codex at the hosted Om MCP endpoint and complete the MCP OAuth login flow.

codex mcp addBash
codex mcp add omtx --url https://agents.omtx.ai/mcp
codex mcp login omtx
~/.codex/config.tomltoml
[mcp_servers.omtx]
url = "https://agents.omtx.ai/mcp"

Why OAuth is shown here

Codex documents OAuth login for streamable HTTP MCP servers that support OAuth. Hosted Om MCP follows that flow, so the documented path is: add the server first, then run codex mcp login omtx.

What to do after restart

  1. Run codex mcp login omtx after adding the hosted server.
  2. Restart Codex so the new MCP server is loaded.
  3. Ask for om_status or pricing_get to confirm the server is attached.
  4. Move into a real workflow such as target search, dataset export retrieval, or job launch.

Good first prompts

  • Use Om MCP to search KRAS and summarize the therapeutic strategy.
  • List available proteins in the Om dataset catalog.
  • Run deep diligence on KEAP1 resistance and show the strongest citations.
  • Launch a Hub workflow and tell me how to track the job.
