Management Commands

MCPProxy provides CLI commands for managing upstream servers and monitoring system health.

Quick Diagnostics

Run this first when debugging any issue:

mcpproxy doctor

The first section is the same needs-attention list mcpproxy attention prints (see Attention Command); the diagnostics follow under Diagnostics: N findings.

It checks for:

• Upstream server connection errors
• OAuth authentication requirements
• Missing secrets
• Runtime warnings
• Docker isolation status

Common Workflow

mcpproxy doctor                     # Check overall health
mcpproxy upstream list              # Identify issues
mcpproxy upstream logs failing-srv  # View logs
mcpproxy upstream restart failing-srv

Upstream Commands

List Servers

mcpproxy upstream list

Output shows unified health status:

• Server name and protocol type
• Tool count
• STATUS: the status label, the same word the Web UI card, the macOS row and the tray show (Online, Connecting, Sign-in required, Needs review, Secret required, Needs configuration, Error, Disabled). A server that is not usable never reads Online, healthy or connected
• ACTION: the CLI command for the server's first suggested action, or -

Example output:

NAME                      PROTOCOL   TOOLS      STATUS                         ACTION
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
✅    github-server           http       15         Online                         -
❌    oauth-server            http       0          Sign-in required               auth login --server=oauth-server

-o json is unchanged and carries health.status, health.usable and health.actions beside every older field.

Filter by status with --status. The flag is repeatable, and a comma-separated value is the same as repeating it (union semantics):

mcpproxy upstream list --status needs_review,sign_in_required
mcpproxy upstream list --status error --status connecting

The values are ready, connecting, sign_in_required, needs_review, needs_secret, needs_config, error and disabled.

Add a Server

mcpproxy upstream add notion https://mcp.notion.com/sse
mcpproxy upstream add fs -- npx -y @modelcontextprotocol/server-filesystem /tmp
mcpproxy upstream add github https://api.githubcopilot.com/mcp/ --secret-header "Authorization: Bearer ghp_..."
mcpproxy upstream add weather --secret-env WEATHER_API_KEY=abc123 -- npx -y weather-mcp

--secret-env KEY=VALUE and --secret-header "Name: value" (both repeatable) write the value to the OS keyring and store ${keyring:<server>-env-<name>} in the config instead of the value. New servers are quarantined. To pick a server from a catalog instead of typing its command, see Catalog Commands.

Review and Approve

New servers and new or changed tools wait for review. mcpproxy review is the one entry point (see Review Commands); the older verbs stay as documented aliases:

Older command	Use instead
mcpproxy upstream approve <server> [tools...]	mcpproxy review approve <server> --tools ...
mcpproxy security approve <server> / security reject	mcpproxy review approve <server> / mcpproxy review reject <server>
mcpproxy tools approve <server>:<tool> / tools reject <server>:<tool>	mcpproxy review approve <server> --tools ... / mcpproxy review reject <server> --tools ...

mcpproxy tools list --risk is an alias of --tier.

View Logs

# View last 100 lines
mcpproxy upstream logs github-server --tail=100

# Follow logs in real-time (requires daemon)
mcpproxy upstream logs github-server --follow

Restart Server

# Restart single server
mcpproxy upstream restart github-server

# Restart all servers
mcpproxy upstream restart --all

Enable/Disable

mcpproxy upstream enable server-name
mcpproxy upstream disable server-name

Patch Headers / Env

mcpproxy upstream patch updates HTTP headers and stdio env on an existing server using JSON Merge Patch semantics — keys you specify are upserted, keys named in --header-remove / --env-remove are deleted, and every other key on the stored config is preserved.

This means you can rotate a single Bearer token without seeing or touching any other header. The same applies to env vars on stdio servers.

# Rotate the Authorization header on a connected server
mcpproxy upstream patch synapbus --header "Authorization: Bearer new-token"

# Add a custom header without disturbing existing ones
mcpproxy upstream patch synapbus --header "X-Trace: on"

# Remove a stale header
mcpproxy upstream patch synapbus --header-remove "X-Old"

# Set + remove in one round-trip
mcpproxy upstream patch synapbus --header "X-New: v" --header-remove "X-Old"

# Update env vars on a stdio server
mcpproxy upstream patch obsidian-pilot \
  --env "LOG_LEVEL=debug" --env-remove "OBSOLETE_VAR"

Flags (all repeatable):

Flag	Semantics
--header NAME: value	Upsert one header (single colon delimits name and value)
--header-remove NAME	Delete a header by name
--env KEY=value	Upsert one env var
--env-remove KEY	Delete an env var by name

Notes:

• Requires the daemon to be running (mcpproxy serve). The subcommand applies changes through the live REST endpoint so connection state and OAuth tokens stay coordinated; editing mcp_config.json by hand is only safe while the daemon is offline.
• Specifying the same key in both --header and --header-remove is a conflict and errors out with a useful message.
• For new servers, use upstream add (HTTP/stdio) or upstream add-json (full JSON shape) instead.

Socket Communication

CLI commands automatically detect and use Unix socket/named pipe communication when the daemon is running.

Benefits of socket mode:

• Reuses daemon's existing server connections (faster)
• Shows real daemon state (not config file state)
• Coordinates OAuth tokens with running daemon
• No redundant server connection overhead

Commands with socket support:

• upstream list/logs/enable/disable/restart/patch
• doctor (requires daemon)
• call tool
• code exec
• tools list
• auth login/status

Standalone commands (no socket needed):

• secrets - Direct OS keyring operations
• trust-cert - File system operations
• search-servers - Registry API operations
