Fixer Automation

What This Skill Does

• This skill automates currency conversion and exchange rate data retrieval using the Fixer toolkit via Rube MCP.
• It enables programmatic access to real-time and historical exchange rates.
• It is useful for developers building financial applications or integrating currency data into their systems.

When to Use

• Convert currencies automatically.
• Get real-time exchange rates.
• Retrieve historical exchange rates.
• Automate financial reporting.
• Integrate currency data into apps.
• Track currency fluctuations.

Key Features

• Uses Rube MCP for tool discovery and execution.
• Requires an active Fixer connection.
• Employs RUBE_SEARCH_TOOLS to find available tools.
• Uses RUBE_MANAGE_CONNECTIONS to manage the Fixer connection.
• Executes tools using RUBE_MULTI_EXECUTE_TOOL.
• Provides a structured workflow for automation.

Manual Installation

Manual installation View Full Skill Content The complete markdown content that gets installed Fixer Automation via Rube MCP

Automate Fixer operations through Composio's Fixer toolkit via Rube MCP.

Toolkit docs: composio.dev/toolkits/fixer

Prerequisites

Rube MCP must be connected (RUBE_SEARCH_TOOLS available) Active Fixer connection via RUBE_MANAGE_CONNECTIONS with toolkit fixer Always call RUBE_SEARCH_TOOLS first to get current tool schemas

Setup

Get Rube MCP: Add https://rube.app/mcp as an MCP server in your client configuration. No API keys needed — just add the endpoint and it works.

Verify Rube MCP is available by confirming RUBE_SEARCH_TOOLS responds Call RUBE_MANAGE_CONNECTIONS with toolkit fixer If connection is not ACTIVE, follow the returned auth link to complete setup Confirm connection status shows ACTIVE before running any workflows

Tool Discovery

Always discover available tools before executing workflows:

RUBE_SEARCH_TOOLS queries: [{use_case: "Fixer operations", known_fields: ""}] session: {generate_id: true}

This returns available tool slugs, input schemas, recommended execution plans, and known pitfalls.

Core Workflow Pattern

Step 1: Discover Available Tools

queries: [{use_case: "your specific Fixer task"}] session: {id: "existing_session_id"}

Step 2: Check Connection

RUBE_MANAGE_CONNECTIONS toolkits: ["fixer"] session_id: "your_session_id"

Step 3: Execute Tools

RUBE_MULTI_EXECUTE_TOOL tools: [{ tool_slug: "TOOL_SLUG_FROM_SEARCH", arguments: {/ schema-compliant args from search results /} }] memory: {}

Known Pitfalls

Always search first: Tool schemas change. Never hardcode tool slugs or arguments without calling RUBE_SEARCH_TOOLS Check connection: Verify RUBE_MANAGE_CONNECTIONS shows ACTIVE status before executing tools Schema compliance: Use exact field names and types from the search results Memory parameter: Always include memory in RUBE_MULTI_EXECUTE_TOOL calls, even if empty ({}) Session reuse: Reuse session IDs within a workflow. Generate new ones for new workflows Pagination: Check responses for pagination tokens and continue fetching until complete
