This guide explains the easiest and most robust way to connect your Polygon account to Hermes. You can do this through either Composio Connect CLI or Composio Connect MCP. For personal use we recommend the CLI, but you won't go wrong with MCP either. ## Also integrate Polygon with - [OpenAI Agents SDK](https://composio.dev/toolkits/polygon/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/polygon/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/polygon/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/polygon/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/polygon/framework/codex) - [OpenClaw](https://composio.dev/toolkits/polygon/framework/openclaw) - [CLI](https://composio.dev/toolkits/polygon/framework/cli) - [Google ADK](https://composio.dev/toolkits/polygon/framework/google-adk) - [LangChain](https://composio.dev/toolkits/polygon/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/polygon/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/polygon/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/polygon/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/polygon/framework/crew-ai) ## TL;DR ### What is Composio Connect? Composio Connect is a consumer offering that lets anyone plug 1,000+ applications directly into their agent harness — including Hermes. It can: - Search and load tools from relevant toolkits on-demand, reducing context usage. - Chain multiple tools to accomplish complex workflows via a remote workbench, without excessive back-and-forth with the LLM. - Manage app authentication end-to-end with zero manual overhead. ## Connect Polygon to Hermes ### Integrating Polygon with Hermes ### Using Composio Connect CLI 1. Install the Composio CLI Run the install script directly, or paste https://composio.dev/hermes into your Hermes chat box to have it installed for you. ```bash curl -fsSL https://composio.dev/install | bash ``` ## What is the Polygon MCP server, and what's possible with it? The Polygon MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Polygon account. It provides structured and secure access to real-time and historical financial market data, so your agent can retrieve market status, analyze price indicators, track dividends, and monitor crypto and stock tickers on your behalf. - Market status and holiday tracking: Instantly check if U.S. exchanges are open or closed and retrieve upcoming market holidays or early closures to plan trading activities. - Comprehensive ticker retrieval: Ask your agent to fetch all available ticker symbols across asset classes, including stocks, crypto, forex, and options, filtered by market or exchange. - Crypto technical analysis: Have your agent calculate moving averages (EMA, SMA), MACD, and RSI indicators for specific cryptocurrencies to support informed trading decisions. - Daily and historical price fetching: Let your agent retrieve daily open/close prices, previous day’s close, or detailed price history for cryptocurrencies and stocks with just a prompt. - Dividend data extraction: Effortlessly access up-to-date corporate dividend information for stocks, enabling portfolio reviews and income analysis. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `POLYGON_GET_ALL_TICKERS` | Get All Tickers | Tool to retrieve all ticker symbols across asset classes. use when you need to filter by market or exchange and paginate through results. | | `POLYGON_GET_CRYPTO_INDICATOR_EMA` | Get Crypto Exponential Moving Average (EMA) | Tool to retrieve exponential moving average (ema) for a cryptocurrency ticker. use when you need crypto ema data for analysis after selecting the time window. | | `POLYGON_GET_CRYPTO_INDICATOR_MACD` | Get Crypto MACD Indicator | Tool to retrieve the macd (moving average convergence/divergence) for a crypto ticker. use when you need momentum analysis for a specific cryptocurrency after confirming ticker and parameters. | | `POLYGON_GET_CRYPTO_INDICATOR_RSI` | Get Crypto RSI Indicator | Tool to retrieve the relative strength index (rsi) for a crypto ticker. use when you need momentum analysis for crypto assets after specifying ticker, timeframe, and optional parameters. | | `POLYGON_GET_CRYPTO_INDICATOR_SMA` | Get Crypto Simple Moving Average (SMA) | Tool to retrieve the simple moving average (sma) for a given crypto ticker. use when you need sma values for a crypto asset after confirming ticker, timespan, and window size. | | `POLYGON_GET_CRYPTO_OPEN_CLOSE` | Get Crypto Open/Close | Tool to fetch daily open and close prices for a given crypto pair on a specified date. use after specifying both currency symbols and the date. | | `POLYGON_GET_CRYPTO_PREV_CLOSE` | Get Crypto Previous Close | Tool to retrieve previous day’s close for a crypto ticker. use when you need the last closing price of a cryptocurrency before analysis or trading. | | `POLYGON_GET_DIVIDENDS` | Get Dividends | Tool to retrieve dividend data for stocks. use when you need corporate dividend information for specific tickers. | | `POLYGON_GET_MARKET_HOLIDAYS` | Get Upcoming Market Holidays | Tool to retrieve upcoming market holidays and half-day closures. use when you need to look up upcoming exchange holidays and early closures. | | `POLYGON_GET_MARKET_STATUS` | Get Market Status | Tool to retrieve current market status. use when you need to know if u.s. exchanges are open, closed, or on holiday. | | `POLYGON_GET_NEWS` | Get News | Tool to retrieve recent news articles related to a ticker. use when you need to fetch financial news after identifying a ticker symbol. | | `POLYGON_GET_REFERENCE_CONDITIONS` | Get reference conditions | Tool to retrieve market condition code mappings. use when you need definitions of trade or quote condition codes after confirming asset class and data type. | | `POLYGON_GET_REFERENCE_EXCHANGES` | Get reference exchanges | Tool to retrieve supported exchanges and their details. use when you need a list of exchanges filtered by asset class or locale. | | `POLYGON_GET_SPLITS` | Get Stock Splits | Tool to retrieve stock split events. use when you need corporate stock split data filtered by ticker or date range. example: "get splits for aapl between 2021-01-01 and 2021-12-31". | | `POLYGON_GET_TECHNICAL_INDICATOR_EMA` | Get Exponential Moving Average (EMA) | Tool to fetch exponential moving average (ema) for a given stock ticker. use when you need historical ema data after confirming ticker, timespan, and window size. | | `POLYGON_GET_TECHNICAL_INDICATOR_SMA` | Get Simple Moving Average (SMA) | Tool to fetch simple moving average (sma) for a given stock ticker. use when you need historical sma data after confirming ticker, timespan, and window size. | | `POLYGON_GET_TICKER_DETAILS` | Get Ticker Details | Tool to retrieve detailed information for a ticker. use when you need an overview of a ticker including company info, market data, and identifiers. | | `POLYGON_GET_TICKER_TYPES` | Get Ticker Types | Tool to retrieve all ticker types supported by polygon.io. use after authenticating to explore ticker categories. | ## Supported Triggers None listed. ## Creating MCP Server - Stand-alone vs Composio SDK The Polygon MCP server provides comprehensive access to Polygon operations through Composio. Once connected, Hermes can perform all major Polygon actions on your behalf using natural language commands. ## Complete Code None listed. ## Conclusion ### Way Forward With Polygon connected, Hermes can now act on your behalf whenever it detects a relevant task or you ask it to. From here, you can extend Hermes further: - Connect more apps: Calendar, Slack, Notion, Linear, and hundreds of others are available through the same Composio Connect setup. Each new integration compounds what Hermes can do for you. - Build workflows across tools: Once multiple apps are connected, Hermes can chain actions together — turn an email into a calendar invite, a Slack message into a Linear ticket, or a meeting note into a follow-up draft. - Let it learn your patterns: The more you use Hermes, the better it gets at anticipating how you'd handle recurring tasks. Give it feedback on drafts and decisions, and it will adapt.

With a standalone Polygon MCP server, the agents and LLMs can only access a fixed set of Polygon tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Polygon and many other apps based on the task at hand, all through a single MCP endpoint. ### Can I use Tool Router MCP with Hermes? Yes, you can. Hermes fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Polygon tools. ### Can I manage the permissions and scopes for Polygon while using Tool Router? Yes, absolutely. You can configure which Polygon scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do. ### How safe is my data with Composio Tool Router? All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Polygon data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
