Codex Setup

Configure Glider with Codex CLI, Codex IDE extension, and Codex app.

Codex

Prerequisite: .NET 10 SDK must be installed before running dotnet tool install --global glider.

dotnet tool install --global glider

Codex starts stdio MCP servers through the configured command. Make sure glider is available on PATH.

# bash/zsh
export PATH="$PATH:$HOME/.dotnet/tools"
which glider

Edit macOS/Linux ~/.codex/config.toml or Windows %USERPROFILE%\.codex\config.toml. Codex CLI, the IDE extension, and the Codex app share this config. Codex MCP docs: developers.openai.com/codex/mcp.

# ~/.codex/config.toml
[mcp_servers.glider]
command = "glider"
args = ["--default-timeout", "30m"]
startup_timeout_sec = 30
tool_timeout_sec = 1800

In the Codex app, open Settings > Integrations & MCP to add or manage the same MCP server configuration. Advanced edits still go through config.toml.

The GliderMCP plugin is published from glidermcp/glidermcp.com and bundles the product skill plus stdio MCP config. After adding the marketplace, install glidermcp from the Codex app Plugin Directory or from the CLI /plugins browser.

codex plugin marketplace add glidermcp/glidermcp.com

If you prefer Streamable HTTP, start Glider yourself and configure Codex with http://localhost:5001/mcp. Use only one glider server entry unless you intentionally want separate stdio and HTTP configs.

glider --transport http --default-timeout 30m

# ~/.codex/config.toml
[mcp_servers.glider]
url = "http://localhost:5001/mcp"
tool_timeout_sec = 1800

Start a new Codex session, then run /mcp to confirm the server is available.

codex
# Then run: /mcp

After connecting GliderMCP, add this product-specific instruction to your MCP client system prompt or project instructions so the agent chooses the right tool surface first.

When working in C#/.NET workspaces, prefer glider mcp semantic tools before shell text search for code navigation and refactoring. Use GliderMCP for symbol lookup, references, implementations, overrides, callers, call graphs, type and project dependencies, diagnostics, impact analysis, and preview-first refactors. Use grep, rg, or find only for non-C# assets, files outside the loaded workspace, generated output, or after GliderMCP cannot load or cannot answer the question.
