Crate re_ghidra_mcp_cc 

Claude-Code-specific glue for the re-ghidra-mcp-cc plugin.

The server, its 19 tools and the Ghidra worker all live in the shared ghidra-mcp crate. What is genuinely Claude-Code-shaped lives here: reading the host’s settings file — .claude/re-ghidra-mcp-cc.local.md on Claude, .opencode/re-ghidra-mcp-opencode.local.md on OpenCode, selected by RE_GHIDRA_HOST — and the preflight the SessionStart hook reports.

Why a settings file matters more for this plugin than for most: one server is one Ghidra project. The project directory, project name and bootstrap program are per-workspace by nature, so without a settings layer every repo needs a hand-written .mcp.json that duplicates the plugin’s registration just to carry three strings.

Structs

Probe

What the environment looks like to the preflight, gathered by the caller.

Enums

Host

Which agent front is running. The settings file is per-host: a session on one host must never read the other host’s file, which is what makes .opencode/…local.md and .claude/…local.md disjoint rather than a migration path between them.

Constants

MIN_JAVA_MAJOR

Ghidra 12.1.2 declares application.java.min=21; anything older fails at JVM start with a message that does not mention the version.

Functions

extract_frontmatter 🔒

Extract the YAML frontmatter block from a .local.md file.

host_from_env

host_from_str over the process environment.

host_from_str

The host named by RE_GHIDRA_HOST. Unset or anything but exactly "opencode" means Host::Claude: the Claude front has never read this variable, so defaulting there keeps every existing install on today’s behavior. OpenCode sets the variable in opencode.jsonc’s mcp.servers.ghidra.environment (Task 5).

load_settings

Load the settings layer for project_dir. A missing or unreadable file is not an error — it simply contributes nothing, and the environment or CLI flags supply the values instead.

parse_java_major

Parse the major version out of java -version output.

preflight

Report what is missing, in the order a user should fix it. An empty vector means every cheap check passed — and the hook then says nothing at all.

settings_from_markdown

The settings-file layer, in the shape the shared config resolver consumes.

settings_path

The settings file this plugin reads, relative to a project root.
