MCP tools — 11 exposed · ~1,061 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability.

Tool Tokens

add_mcp ~272

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

Input Output Examples

Name	Type	Req	Description
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	yes	Name for the new MCP server (alphanumeric, dashes, underscores)
transport	string	yes	Transport type: stdio for local process, http/sse for remote server
url	string	—	Server URL (required for http/sse transport)

No output schema declared.

No examples provided.

check_mcp_health ~48

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

Input Output Examples

Name	Type	Req	Description
mcp_name	string	yes	The name of the MCP server to check

No output schema declared.

No examples provided.

configure_mcp ~160

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

Input Output Examples

Name	Type	Req	Description
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	yes	The name of the MCP server to configure
updates	object	yes	Fields to update in the MCP server config

No output schema declared.

No examples provided.

get_mcp_details ~68

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

Input Output Examples

Name	Type	Req	Description
mcp_name	string	yes	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 '***').

No output schema declared.

No examples provided.

list_all_mcps ~101

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 Output Examples

Name	Type	Req	Description
show_env_values	boolean	—	If true, reveal raw 'env' values. Default false (values shown as '***').

No output schema declared.

No examples provided.

remove_mcp ~42

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

Input Output Examples

Name	Type	Req	Description
mcp_name	string	yes	The name of the MCP server to remove

No output schema declared.

No examples provided.

restart_codex_mcp_process ~84

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 Output Examples

Name	Type	Req	Description
mcp_name	string	yes	The mcp_servers.<name> entry in ~/.codex/config.toml to restart

No output schema declared.

No examples provided.

restart_mcp_process ~74

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 Output Examples

Name	Type	Req	Description
mcp_name	string	yes	The name of the MCP server whose process should be restarted

No output schema declared.

No examples provided.

unwrap_mcp_stdio ~50

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

Input Output Examples

Name	Type	Req	Description
mcp_name	string	yes	The name of the MCP server to unwrap

No output schema declared.

No examples provided.

wrap_codex_mcp_stdio ~91

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 Output Examples

Name	Type	Req	Description
mcp_name	string	yes	The mcp_servers.<name> entry in ~/.codex/config.toml to wrap

No output schema declared.

No examples provided.

wrap_mcp_stdio ~71

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 Output Examples

Name	Type	Req	Description
mcp_name	string	yes	The name of the MCP server to wrap

No output schema declared.

No examples provided.
