AnyAPI MCP server for AI agents and assistants
Securely connect your AI agents and chatbots (Claude, ChatGPT, Cursor, etc) with AnyAPI MCP or direct API to validate data, convert currencies, check holidays, generate documents, and retrieve web data through natural language.
Api Key
AnyAPI is a marketplace of utility APIs for validation, currency conversion, holidays, documents, and web data. It brings common application workflows together through one practical API platform.

SETUP GUIDE
Connect AnyAPI MCP Tool with your Agent
1
Install Composio
typescript
npm install @composio/core ai @ai-sdk/mcp @ai-sdk/openaiInstall the Composio SDK and your agent framework
2
Create a session with MCP enabled
typescript
import { Composio } from "@composio/core";
const composio = new Composio();
const { mcp } = await composio.create("your-user-id", {
toolkits: ["anyapi"],
mcp: true,
});Create a session scoped to AnyAPI and read its MCP URL and headers
3
Connect your agent to the MCP server
typescript
import { createMCPClient } from "@ai-sdk/mcp";
import { openai } from "@ai-sdk/openai";
import { generateText, stepCountIs } from "ai";
const client = await createMCPClient({
transport: { type: "http", url: mcp.url, headers: mcp.headers },
});
const { text } = await generateText({
model: openai("gpt-5.6-sol"),
tools: await client.tools(),
prompt: "Convert 100 USD to EUR using AnyAPI",
stopWhen: stepCountIs(10),
});
console.log(text);
await client.close();Pass the session's MCP URL and headers to your agent and run a AnyAPI request
SETUP GUIDE
Connect AnyAPI API Tool with your Agent
1
Install Composio
typescript
npm install @composio/core @composio/openai openaiInstall the Composio SDK, the OpenAI provider, and the OpenAI SDK
2
Create a Composio session
typescript
import OpenAI from "openai";
import { Composio } from "@composio/core";
import { OpenAIResponsesProvider } from "@composio/openai";
const composio = new Composio({ provider: new OpenAIResponsesProvider() });
const client = new OpenAI();
const session = await composio.create("your-user-id", { toolkits: ["anyapi"] });
const tools = await session.tools();Initialize Composio with the OpenAI Responses provider and create a session scoped to AnyAPI
3
Run AnyAPI tools with your agent
typescript
let response = await client.responses.create({
model: "gpt-5.6-sol",
tools,
input: [{ role: "user", content: "Convert 100 USD to EUR using AnyAPI" }],
});
while (response.output.some((o) => o.type === "function_call")) {
const outputs = await composio.provider.handleToolCalls(session, response.output);
response = await client.responses.create({
model: "gpt-5.6-sol",
tools,
previous_response_id: response.id,
input: outputs,
});
}
console.log(response.output_text);Send a request, execute the AnyAPI tool calls through the session, and print the final answer

FAQ
Frequently asked questions
Yes, AnyAPI requires you to configure your own API key credentials. Once set up, Composio handles secure credential storage and API request handling for you.
Yes! Composio's Tool Router enables agents to use multiple toolkits. Learn more.
Yes. Composio is SOC 2 Type II compliant and is built to keep your AnyAPI connection and credentials secure. OAuth tokens and API keys are encrypted, and sensitive customer data is protected at rest and in transit.
Composio also undergoes independent security testing and continuously monitors its systems for security threats. You can review the latest reports and policies in the Composio Trust Center.
Composio maintains and updates all toolkit integrations automatically, so your agents always work with the latest API versions.
Create the key in your AnyAPI account settings, then paste it once on Composio's connection page. Composio stores it encrypted and uses it only for the AnyAPI actions your agent runs. Nobody else in your workspace can read it, and you can revoke it inside AnyAPI at any time.
When you connect a AnyAPI account through Composio, every action runs under that account, so anything the agent creates, sends, or changes shows up in AnyAPI as done by you. Keep an approval step in your prompt for actions with side effects, such as sending or deleting, and have the agent draft first.
Whatever the credentials you connect allow inside AnyAPI. If AnyAPI lets you scope a key to specific permissions, create a scoped one so the agent can only do what you intend. You can revoke the key inside AnyAPI at any time.
Yes. Composio supports multiple connected accounts for the same app, and that works in Claude, ChatGPT, or any other assistant you connect through Composio. Give each AnyAPI connection a name such as work or personal, and the assistant uses the one you mention in the request. Each account keeps its own credentials and nothing is merged.
The connection stops working the moment AnyAPI rejects the old key. Create a new key in AnyAPI and reconnect the account from the Composio dashboard or by asking your agent to reconnect AnyAPI. Nothing else changes.
Composio's free Hobby plan includes 100,000 tool calls per month with no credit card, which covers most personal AnyAPI use. Paid plans add higher limits and team features. Your AnyAPI plan and its API limits still apply as usual.
Built-in connectors usually give one AI access to a limited set of apps. Many people use Composio because it lets their AI connect to more apps than it normally supports, or connect to multiple accounts for the same app (e.g. connect Claude to multiple AnyAPI accounts).
With Composio, you connect AnyAPI once and then use it across different AI assistants without setting it up separately in each one. Connect your apps to Composio once, then connect Composio to whichever AI you use, whether that's Claude, ChatGPT, Hermes, or your own custom assistant.
