How to connect a Slack MCP with Codex (4 steps)

Merge's integration platform offers a streamlined method for connecting Codex to Slack using the Merge Agent Handler, enabling developers to access detailed Slack discussions directly when working on coding tasks. This approach resolves issues with Codex missing crucial context and nuances from Slack threads that are often reduced to brief summaries in task descriptions. By utilizing the Merge CLI, developers can securely connect Codex to Slack, with Merge managing credential storage and access scopes to ensure secure and reliable interactions. This integration is particularly beneficial for engineering teams who do much of their planning and decision-making in Slack, as it allows Codex to generate code and documentation based on the actual discussions, constraints, and decisions captured in Slack threads. The solution also provides audit logging and scoped access, which is essential for teams handling sensitive information or requiring detailed oversight of Codex's interactions with Slack.
