+description: Install codedb for Codex users and register it as an MCP server. Use when someone wants to install the hosted release build, build codedb from source, re-register a local codedb binary in Codex, or switch Codex to a different codedb executable.
+---
+
+# codedb Install
+
+Use this skill when a Codex user wants `codedb` available as an MCP server.
+
+Prefer the hosted installer for normal setup:
+
+```bash
+curl -fsSL https://codedb.codegraff.com/install.sh | sh
+```
+
+Use a source build when the user wants local changes, debug builds, or a branch that is not yet released:
+
+```bash
+git clone https://github.com/justrach/codedb.git
+cd codedb
+zig build -Doptimize=ReleaseFast
+```
+
+The built binary will usually be at `zig-out/bin/codedb`.
+
+After either path, verify the binary starts:
+
+```bash
+/absolute/path/to/codedb --help
+```
+
+Then register that binary in Codex with the helper script:
+
+```bash
+./skills/codedb-install/scripts/register_codex_mcp.sh /absolute/path/to/codedb
+```
+
+The script appends this MCP entry only when it is not already present:
+
+```toml
+[mcp_servers.codedb]
+command = "/absolute/path/to/codedb"
+args = ["mcp"]
+startup_timeout_sec = 30
+```
+
+If the user wants to replace an existing `codedb` entry with a different binary, edit `~/.codex/config.toml` directly after checking the current value.
