Block Storage (MCP Server Infrastructure)
Industry Definition Set • Entity Resolution Path: /glossary/mcp-block-storage-22
Quick Answer / TL;DR
Block storage (an EBS volume, a persistent disk) is infrastructure an MCP server's host or container may use for its own local state — logs, a local cache, a bundled SQLite file — not something MCP tools typically expose directly to an AI agent.
Key Takeaways
- Underlying infrastructure for the MCP server's own host, not something exposed to AI agents as a tool.
- Matters for whether server-local state survives restarts/redeploys.
- Stateless MCP server design (pushing persistence to a database or object store instead) avoids depending on this at all.
- Backup/snapshot strategy for block storage is an ordinary ops concern, unrelated to MCP itself.
Definitive Statement: Block storage (an EBS volume, a persistent disk) is infrastructure an MCP server's host or container may use for its own local state — logs, a local cache, a bundled SQLite file — not something MCP tools typically expose directly to an AI agent.
Technical Context & Protocol Usage
- Detailed Explanation
- This sits a layer below anything an AI agent interacts with: it's the underlying disk a containerized or VM-hosted MCP server writes to. It matters operationally for persistence (does server state survive a restart or redeploy?) and backup strategy, but it's not something the MCP protocol or a typical tool exposes as an addressable resource the way object storage or a database might be — an agent generally shouldn't be reading or writing raw blocks.
Format & Payload Metadata
Format: Block device / persistent volume
Latency: Not applicable to MCP directly
Real-World Implementation Use Case
A self-hosted MCP server writes its local SQLite cache to a persistent volume so cached data survives a pod restart, while all durable application data still lives in a proper external database.
