Momento MCP Server

Momento MCP Server is an MCP server that provides an interface to Momento's serverless caching service for AI agents and developer workflows. It connects Model Context Protocol clients directly to Momento Cache, enabling developers, data engineers, and automated agents to read, write, and manage key-value cache data without managing physical cache infrastructure. By exposing both data plane and control plane operations, the server allows AI models to retrieve cached items, set keys with custom time-to-live settings, and handle administrative operations across Momento accounts. Users can query cache hits and misses, store structured session contexts, and inspect existing caches directly within their workspace. The integration simplifies caching operations in serverless architectures, empowering language models to access fast, low-latency storage for context persistence, session state tracking, and rate limiting data while executing conversational or agentic workloads.

How to install and configure Momento MCP Server

1. Obtain a Momento API key from the Momento Console. Ensure you use a super user API key if you need to run control plane commands. 2. Open your Claude Desktop configuration file and add the server under the mcpServers object: json { "mcpServers": { "momento": { "command": "npx", "args": [ "-y", "@gomomento/mcp-momento" ], "env": { "MOMENTO_API_KEY": "your-api-key", "MOMENTO_CACHE_NAME": "your-cache-name", "DEFAULT_TTL_SECONDS": 60 } } } } 3. Restart Claude Desktop to start using Momento tools.

What you can do with Momento MCP Server

• Persisting conversational session states or user contexts across multiple client interactions using cache keys with custom time-to-live settings. - Inspecting and querying active serverless caches directly from an LLM prompt to diagnose missing keys and cache performance. - Creating and provisioning new Momento cache instances dynamically during automated setup tasks or multi-tenant operations. - Storing and retrieving precomputed intermediate prompt completions or agent reasoning steps to reduce downstream API latency and repetitive computation. - Clearing or deleting unused cache clusters programmatically to clean up test environments and regulate resource allocation across accounts.

How do I install Momento MCP Server?

You can run it directly using npx by configuring @gomomento/mcp-momento in your MCP client configuration file. You must supply your Momento API key in the environment variables, along with an optional cache name and default time-to-live setting in seconds.

What tools does Momento MCP Server provide?

It provides tools to get key values, set key-value pairs with customizable time-to-live values, list existing cache instances across your account, create new caches, and delete existing caches.

Which MCP clients work with Momento MCP Server?

It works with MCP-compliant environments including Claude Desktop and the MCP Inspector. Any client capable of executing commands via standard input/output through npx can integrate with this server.

Why do some cache management tools fail to execute?

Tools like list-caches, create-cache, and delete-cache manage the control plane. They require a super user API key generated from the Momento Console to execute successfully.
