And MCP makes the experience even better. With Highergov MCP integration, you can draft, triage, summarise emails, and much more, all without leaving the terminal or the app, whichever you prefer. ## Also integrate Highergov with - [OpenAI Agents SDK](https://composio.dev/toolkits/highergov/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/highergov/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/highergov/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/highergov/framework/claude-cowork) - [OpenClaw](https://composio.dev/toolkits/highergov/framework/openclaw) - [Hermes](https://composio.dev/toolkits/highergov/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/highergov/framework/cli) - [Google ADK](https://composio.dev/toolkits/highergov/framework/google-adk) - [LangChain](https://composio.dev/toolkits/highergov/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/highergov/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/highergov/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/highergov/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/highergov/framework/crew-ai) ## TL;DR ### Why use Composio? Apart from a managed and hosted MCP server, you will get: - CodeAct: A dedicated workbench that allows GPT to write its code to handle complex tool chaining. Reduces to-and-fro with LLMs for frequent tool calling. - Large tool responses: Handle them to minimise context rot. - Dynamic just-in-time access to 20,000 tools across 1000+ other Apps for cross-app workflows. It loads the tools you need, so GPTs aren't overwhelmed by tools you don't need. ## Connect Highergov to Codex ### How to install Highergov MCP in Codex ### Run the setup command Run this command in your terminal to add the Composio MCP server to Codex. ```bash codex mcp add composio --url https://connect.composio.dev/mcp ``` ## What is the Highergov MCP server, and what's possible with it? The Highergov MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Highergov account. It provides structured and secure access to government contracting and grant intelligence, so your agent can perform actions like searching contracts, analyzing award history, retrieving agency details, and fetching grant data on your behalf. - Comprehensive contract search and retrieval: Quickly have your agent look up federal contracts, filter by last modified date, or leverage saved searches to find exactly what you need. - Award and grant history analysis: Direct your agent to access detailed award and grant histories, making it simple to track funding trends across agencies or time periods. - Agency and program intelligence: Ask your agent to list and explore government agencies, defense programs, or contract vehicles to support your market research. - Document and opportunity extraction: Let your agent fetch associated documents or list DLA contract opportunities for deeper due diligence and competitive analysis. - IDV and contract vehicle tracking: Monitor Indefinite Delivery Vehicles (IDVs) and contract vehicles to better understand procurement patterns and strategic opportunities. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `HIGHERGOV_GET_AGENCIES` | Get Agencies | Retrieves government agency information from the HigherGov database with pagination support.

With a standalone Highergov MCP server, the agents and LLMs can only access a fixed set of Highergov tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Highergov and many other apps based on the task at hand, all through a single MCP endpoint. ### Can I use Tool Router MCP with Codex? Yes, you can. Codex 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 Highergov tools. ### Can I manage the permissions and scopes for Highergov while using Tool Router? Yes, absolutely. You can configure which Highergov 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 Highergov data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
