## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-08-03.

- **Supply Chain Security**: 86/100

## MCP tools (11)

### `list_all_mcps` (~101 tokens)

List all configured MCP servers from ~/.claude.json with their configuration. By default, values inside each server's 'env' field are redacted to '***' so this tool can't be used to exfiltrate API keys stored in MCP env. Pass show_env_values=true to reveal them when you legitimately need them.

Input parameters:

- `show_env_values` (boolean): If true, reveal raw 'env' values. Default false (values shown as '***').

### `get_mcp_details` (~68 tokens)

Get the full configuration for a specific MCP server by name.

Input parameters:

- `mcp_name` (string, required): The name of the MCP server to get details for
- `show_env_values` (boolean): If true, reveal raw 'env' values. Default false (values shown as '***').

### `check_mcp_health` (~48 tokens)

Check the health of an MCP server — whether it is configured, wrapped, and its process is running.

Input parameters:

- `mcp_name` (string, required): The name of the MCP server to check

### `restart_mcp_process` (~74 tokens)

Restart the underlying process for an MCP server by finding and killing its process. For wrapped stdio MCPs (via wrap_mcp_stdio), the wrapper will respawn automatically; otherwise you typically need to restart Claude CLI.

Input parameters:

- `mcp_name` (string, required): The name of the MCP server whose process should be restarted

### `restart_codex_mcp_process` (~84 tokens)

Restart a Codex CLI MCP server process. Works reliably only for wrapped MCPs (via wrap_codex_mcp_stdio) by killing the wrapped child PID from its pidfile; otherwise you typically need to restart Codex CLI.

Input parameters:

- `mcp_name` (string, required): The mcp_servers.<name> entry in ~/.codex/config.toml to restart

### `wrap_mcp_stdio` (~71 tokens)

Wrap a stdio MCP server so it can be restarted reliably. Updates ~/.claude.json to launch a Node wrapper that spawns the original command and respawns it when killed. Requires restarting Claude CLI to take effect.

Input parameters:

- `mcp_name` (string, required): The name of the MCP server to wrap

### `unwrap_mcp_stdio` (~50 tokens)

Unwrap a previously wrapped stdio MCP server, restoring its original command. Requires restarting Claude Code to take effect.

Input parameters:

- `mcp_name` (string, required): The name of the MCP server to unwrap

### `wrap_codex_mcp_stdio` (~91 tokens)

Wrap a Codex CLI stdio MCP server (from ~/.codex/config.toml) so it can be restarted reliably. Rewrites the MCP entry to launch mcpgo's Node wrapper that respawns the original command. Restart Codex CLI to take effect.

Input parameters:

- `mcp_name` (string, required): The mcp_servers.<name> entry in ~/.codex/config.toml to wrap

### `configure_mcp` (~160 tokens)

Update the configuration of an existing MCP server. Merges provided updates into the existing config.

Input parameters:

- `allow_footgun_args` (boolean): Set true to override the safety refusal when updates.args include code-injection flags like -e/--eval/-c.
- `allow_footgun_env` (boolean): Set true to override the safety refusal when updates.env sets a code-injection key like NODE_OPTIONS, LD_PRELOAD, PYTHONSTARTUP.
- `allow_shell_metacharacters` (boolean): Set true to override the safety refusal when 'updates.command' contains shell metacharacters.
- `mcp_name` (string, required): The name of the MCP server to configure
- `updates` (object, required): Fields to update in the MCP server config

### `remove_mcp` (~42 tokens)

Remove an MCP server from the user configuration (~/.claude/mcp.json).

Input parameters:

- `mcp_name` (string, required): The name of the MCP server to remove

### `add_mcp` (~272 tokens)

Add a new MCP server to the user configuration (~/.claude.json).

Input parameters:

- `allow_footgun_args` (boolean): Set true to override the safety refusal when args include code-injection flags like -e/--eval on node, -c on python/bash, -Command on pwsh, /c on cmd.
- `allow_footgun_env` (boolean): Set true to override the safety refusal when env sets a code-injection key like NODE_OPTIONS, LD_PRELOAD, PYTHONSTARTUP, BASH_ENV.
- `allow_shell_metacharacters` (boolean): Set true to override the safety refusal when 'command' contains shell metacharacters. Use only for genuinely shell-style commands you trust.
- `args` (array): Arguments to pass to the command
- `command` (string): Command to run (required for stdio transport)
- `env` (object): Environment variables to set for the server
- `headers` (object): HTTP headers (for http/sse transport)
- `mcp_name` (string, required): Name for the new MCP server (alphanumeric, dashes, underscores)
- `transport` (string, required): Transport type: stdio for local process, http/sse for remote server
- `url` (string): Server URL (required for http/sse transport)
