mcp-launchpad
mcp-launchpad (mcpl) is a Python CLI/assistant-friendly launcher that discovers and executes tools exposed by multiple MCP (Model Context Protocol) servers. It supports local server processes (e.g., via command/args) plus remote MCP HTTP/SSE endpoints, provides a persistent session daemon for repeated calls, and includes OAuth 2.1 (PKCE) authentication for OAuth-protected remote servers.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
README describes OAuth 2.1 with PKCE (S256), token encryption at rest (Fernet) and OS keyring integration with fallback encryption if keyring unavailable, plus TLS enforcement for OAuth endpoints. However, secret handling for non-OAuth headers (e.g., Bearer tokens in mcp.json) is configuration-driven, so operator hygiene is still required. Dependency hygiene/CVE status is not verifiable from provided data.
⚡ Reliability
Best When
You want an agent to reliably discover and call MCP tools via bash/CLI, and you have MCP servers configured locally and/or remote OAuth-protected MCP endpoints with tokens already set up.
Avoid When
You need first-class programmatic access beyond CLI usage (e.g., no SDK/OpenAPI), or you cannot allow the CLI to spawn configured local server commands or manage local token storage.
Use Cases
- • Search and enumerate tools across multiple MCP servers from the command line
- • Inspect tool schemas and examples for MCP tools
- • Execute MCP tool calls from an agent by running a CLI command
- • Manage OAuth authentication (login/status/logout) for OAuth-protected MCP servers
- • Use a session daemon to keep MCP connections warm for faster repeated tool calls
Not For
- • Running as a long-lived server process exposed to untrusted networks (it’s a local CLI tool)
- • Automating OAuth flows end-to-end without prior human browser interaction
- • Environments where executing arbitrary configured server commands (e.g., npx/uvx) is unacceptable
- • Use as a general-purpose HTTP/REST API for external systems
Interface
Authentication
OAuth requires interactive browser authorization for agents; tokens are stored locally and managed via mcpl auth login/logout/status. For remote HTTP servers, headers and OAuth can be configured.
Pricing
No pricing information provided; described as an open-source CLI.
Agent Metadata
Known Gotchas
- ⚠ Agents can’t complete OAuth browser callback flows; OAuth-protected servers must be authenticated in advance using mcpl auth login.
- ⚠ If multiple config files are discovered, mcpl may prompt for selection; agents should ensure the intended config selection is already made (or preferences activated).
- ⚠ Daemon lifecycle/cleanup depends on IDE/parent process detection and idle timeout; long-running sessions may require mcpl session status/stop or adjusting MCPL_IDLE_TIMEOUT.
- ⚠ Configured server commands may spawn external processes (e.g., npx/uvx), so sandboxing may be needed in restricted environments.
