## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Endpoint Security**: 11/100
  - TLS not yet verified: we couldn't open a connection to check the certificate.
  - Authorisation not yet verified: we couldn't confirm whether this endpoint requires it.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS not yet verified: we couldn't read the response headers to check for it.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 0/100
  - Transport check failed: declared streamable-http, but we couldn't connect to verify it.
- **Schema Quality & AI Usability**: 0/100
  - Schema not yet verified: we couldn't read the endpoint's schema, or could read only part of its tool list.
- **Stability & Change Management**: 0/100

### How do I install the Attic Standard MCP server?

Attic Standard is a hosted endpoint at https://mcp.atticstandard.com/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

## MCP tools (11)

### `get_index_benchmarks` (~428 tokens)

Attic Standard index benchmarks

The Attic Standard price indexes for AI inference: every published index at the week the site shows.

Six families: Modality (text, multimodal, image, video, audio, voice, embeddings), Channel (model developers, cloud marketplaces, inference platforms, neoclouds), Tier (flagship, core, compact), License (open weights, restricted weights, proprietary), Origin (United States, China) and Use case (reasoning, coding).

For each index and direction (input, cached input, output) it returns the benchmark level (May 2026 = 100; regional EUR and CNY versions October 19, 2026 = 100) with week, month and vs-base changes, the spot price (median, p25, p75, in dollars, or in euros or yuan for regional versions) with its own week, month and vs-base changes, and coverage counts with the May 2026 basket size, flagged where the basket has changed materially since the base.

Free: fully public, the same figures atticstandard.com publishes. Token prices are per 1,000 tokens; other modalities use their own unit (per image, per second, per minute, per 1,000 characters).

Examples:
  \- "Where is text inference priced this week?" -> index_code="TXT"
  \- "Compare the four channels" -> index_category="Channel"
  \- "Open-weight versus proprietary" -> index_category="License"

Input parameters:

- `_atom_api_key` (string): Your Attic Standard MCP PRO key for vendor- and SKU-level data. Omit for the free tier.

With model_name: every vendor's price for that model week by week, showing when each SKU was repriced; Attic Standard MCP PRO.

Token prices are per 1,000 tokens; other modalities use their own unit (per image, per second, per minute, per 1,000 characters).

## Common questions

### What is the Attic Standard MCP server?

Attic Standard is an MCP server listed in the public MCP registry as io.github.AtticStandard/atom-mcp-server. The global price benchmark for AI inference: 23 price indexes, market KPIs and SKU-level prices. This page covers its hosted endpoint (https://mcp.atticstandard.com/mcp).

### Is the Attic Standard MCP server safe to use?

Attic Standard scores 82 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Attic Standard MCP server expose?

Attic Standard exposes 11 tools: get_index_benchmarks, get_price_history, get_kpis, get_model_intelligence, get_index_constituents, and 6 more. Their descriptions and schemas cost roughly 2,727 tokens of context every time the server is loaded.

### Does the Attic Standard MCP server require authentication?

Its publisher declares no required credentials for Attic Standard. We have not been able to confirm that against the live endpoint, and a server can require authorisation without declaring it here.

### Is the Attic Standard MCP server still maintained?

Attic Standard is still listed in the MCP registry, though our most recent checks did not reach this channel. We last reached this channel on 4 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What did VerifyMCP test on the Attic Standard MCP server?

VerifyMCP ran 3 checks on Attic Standard, covering HTTPS, DNSSEC and Transport. 8 items could not be completed, a gap on our side rather than a finding about Attic Standard: TLS certificate, Authorization, HSTS header, Schema quality and 4 more. 5 categories score 0 for that reason, because we only credit what we can confirm. Supply Chain Security and Provenance & Transparency do not apply to a hosted endpoint, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
