Object Hash Engine

What is the Object Hash Engine MCP Server?

Your agent needs to check if an API response has changed since the last fetch. It hashes the new JSON and gets a different fingerprint, triggering a massive downstream pipeline update. But the data didn't actually change — the API just returned the keys in a different order.

This MCP uses node-object-hash to generate mathematically consistent SHA-256 fingerprints. It recursively sorts all keys before hashing, guaranteeing that identical data structures always produce identical hashes, regardless of how they were constructed.

The Superpowers

  • Deterministic Hashing: {a:1,b:2} and {b:2,a:1} will yield the exact same SHA-256 hash.
  • Deep Structure Support: Hashes complex nested objects, arrays, nulls, and dates accurately.
  • Cache Invalidation: The perfect tool for building ETags, checking for state drift, and busting caches.
  • Zero Hallucination: Agents can't reliably compare large strings. Hashing gives them a tiny, mathematically absolute proof of equality.

Built-in capabilities (1)

hash_json_object

Generate a deterministic SHA-256 fingerprint of any JSON object. Sorts keys automatically. Essential for deduplication and cache invalidation

Why VS Code Copilot?

GitHub Copilot Agent mode brings Object Hash Engine data directly into your VS Code workflow. With a project-scoped config, the entire team shares access to 1 tools. Copilot queries live data, generates typed code, and writes tests from actual API responses, all without leaving the editor.

  • VS Code is used by over 70% of developers. adding MCP tools to Copilot means your team can leverage external data without leaving their primary editor

  • Project-scoped MCP configs (.vscode/mcp.json) let you commit server configurations to your repository, ensuring the entire team shares the same tool access

  • Copilot's Agent mode integrates MCP tools seamlessly with file editing, terminal commands, and workspace search in a single agentic loop

  • GitHub's enterprise compliance and audit features extend to MCP tool usage, providing visibility into how AI interacts with external services

FAQ

Frequently asked questions

01

Why not just use regular SHA-256 on a JSON string?

If you stringify an object, the key order matters. JSON.stringify({a:1,b:2}) and JSON.stringify({b:2,a:1}) result in completely different strings, and thus completely different hashes, even though the data is semantically identical. This engine fixes that.

02

Does it handle arrays properly?

Yes. While object keys are sorted to ensure determinism, array elements are NOT sorted, because in arrays, order represents semantic meaning (index 0 vs index 1).

03

Can I use this for deduplication in a database?

Absolutely. Hash the payload with this engine and store the hash as a unique index in your database. If another agent tries to insert the same payload (even with keys in a different order), the database will reject the duplicate hash.

04

Which VS Code version supports MCP?

MCP support requires VS Code 1.99 or later with the GitHub Copilot extension. Ensure both are updated to the latest version. Older versions of Copilot may not expose the Agent mode toggle.

05

How do I switch to Agent mode?

Open the Copilot Chat panel and look for two mode options: "Ask" and "Agent". Click "Agent" to enable autonomous tool calling. In Ask mode, Copilot provides conversational answers but cannot invoke MCP tools.

06

Can I restrict which MCP tools Copilot can access?

Yes. VS Code shows a tool consent dialog before any MCP tool is invoked for the first time. You can also configure tool access policies at the organization level through GitHub Copilot settings.

07

Does MCP work in VS Code Remote or Codespaces?

Yes. MCP servers configured via .vscode/mcp.json work in Remote SSH, WSL, and GitHub Codespaces environments. The MCP connection is established from the remote host, so ensure the server URL is accessible from that environment.

08

MCP tools not available

Ensure you are in Agent mode in Copilot Chat. MCP tools only appear in Agent mode.
