Overview

Description from the maker (original English)

Discover reusable source, data and memory capabilities; inspect release evidence and compatibility.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs in the cloud
  • Transport: Streamable HTTP
  • Category: Search & AI memory
  • You need to fill in: Authorization

Install

Pick the AI app you use, then copy the settings.

Before you install

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Run this in your terminal

claude mcp add --transport http daystruct https://api.daystruct.ai/mcp --header 'Authorization: your-value'

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "daystruct": {
      "url": "https://api.daystruct.ai/mcp",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "daystruct": {
      "type": "http",
      "url": "https://api.daystruct.ai/mcp",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

    Deprecated: this evidence tool is no longer refreshed and will be removed on or after 2026-12-31. For building, use discover_daystruct_capabilities and compat_check. Given a need -- minimum context window, required capabilities, a price ceiling -- return the models that satisfy i

  • read_recent_evidence_changes

    Deprecated: this evidence tool is no longer refreshed and will be removed on or after 2026-12-31. For building, use discover_daystruct_capabilities and compat_check. Read the bounded canonical change feed.

  • compat_check

    Resolve Daystruct capabilities to exact versions that fit each other, or get the exact constraint that broke with suggested alternatives. Send the project manifest by default: project.runtime (the node or python version the project runs), project.platform, and the project's packa

  • get_compat_verify_kit

    Return the files of the local verify step for exact source members from compat_check: a script, its plan, and the interface conformance suites. Write them to a scratch directory and run `node daystruct-verify.mjs` from the user's project; it runs the members' own tests and confor

  • get_daystruct_validated_guidance

    Retrieve reviewed Frontier guidance scoped to an exact databank, task family and tested model. Returns only live, unexpired promotions and their evidence limits; never private test fixtures.

  • list_daystruct_guidance_scopes

    Find task families and exact tested models with live Frontier guidance for a databank, before requesting that guidance.

  • plan_project_development

    Get a small stage-specific capability selection and concrete next actions from a caller-approved project projection. Keep source and full snapshots local. Caller-reported outcomes are not verified execution. Does not acquire, execute, store project context or send reminders.

  • get_daystruct_account

    Read the connected key's account: available and reserved credits, the key's scopes, its per-call spending limit (null means none) and where the owner adds credits. Check this before a paid call, show the user the price first, and tell them what was spent afterwards. Read-only; ne

  • resolve_task_capabilities

    Select relevant capabilities progressively, or request full delivery. Charges the published resolve price (/api/v1/pricing) to a key with read + requests:write; data.economics reports chargedCredits and creditsRemaining. Optional maxPriceCredits caps this call. Optional task sess

  • create_task_session

    Start compact task context with optional capability steps and dependencies. Requires read and requests:write. No conversation or reasoning trace is stored.

  • record_task_event

    Report viewed, called, succeeded, failed or skipped capability status, or task stage. Usage and outcomes remain client-reported.

  • get_task_session

    Read compact task context or preview the next ready capabilities without consuming them or extending the session TTL.

  • close_task_session

    Close a task with its reported outcome and compact summary.

  • search_daystruct_library

    Search this account's saved or owned capabilities and bundles. Returns a small shortlist; saving does not acquire, execute or grant access to source. Inspect a selected profile before use.

  • resolve_daystruct_bundle

    Read a saved, owned or public bundle with pinned source versions and current member availability. Returns a composition plan, not an execution or purchase. Each capability retains its usage terms.

  • discover_daystruct_capabilities

    Browse every public Daystruct capability without an account, or search using a task sentence or tool name. Lists default to eight compact descriptors. Set limit (1-100) and offset to follow meta.nextOffset until null; view: full returns up to 100 full metadata records per page. C

  • prepare_daystruct_capabilities

    Group up to six discovered capability IDs into a plan with each profile and delivery instructions. Missing entries remain explicit. Does not acquire, execute, check combined compatibility or charge credits. Your agent can combine these pieces with Daystruct knowledge and verify t

  • get_daystruct_card_image

    Get the image of a Daystruct card (Source, Data or Memory) to show the user beside your text when you introduce, use, update or report on that card. Pass the card's ID (cap_…) or exact reference, never a guessed name. Returns PNG image content plus the card's name, type and page

Common questions

Is Daystruct safe?

It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: Authorization

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.3.0) reached the registry 4 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Context7, Codebase Memory, Exa
