## 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**: 80/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 73/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 403 tokens (~134/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 63/100
  - Stability observed for 19 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

### `list_products` (~108 tokens)

List products

Input parameters:

- `category` (string): Category slug, for example analytics.
- `limit` (integer): How many products to return (default 50).
- `offset` (integer): How many products to skip (default 0).
- `q` (string): Part of a product name or domain.

### `get_product_summary` (~79 tokens)

Get a product summary

What users of one product struggle with: counts, the main problem areas, and the free-preview reports per category (pain points, feature requests, workarounds, switching reasons) with their source links, plus the page and pricing links for the full list.

Input parameters:

- `product` (string, required): Product slug, name or domain, for example grafana.

### `search_items` (~101 tokens)

Search feedback reports

Search the free-preview feedback reports of one product, optionally by category and by words in the title or summary (all words must match). Each report carries the source threads (URL, date, quoted excerpt, state) behind it.

## Common questions

### What is the Friction MCP server?

Friction is an MCP server listed in the public MCP registry as com.grain64.friction/friction. Sourced pain points and feature requests of B2B software users, read-only, with source links. This page covers its hosted endpoint (https://friction.grain64.com/mcp).

### Is the Friction MCP server safe to use?

Friction 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 Friction MCP server expose?

Friction exposes 3 tools: list_products, get_product_summary, search_items. Their descriptions and schemas cost roughly 288 tokens of context every time the server is loaded.

### Does the Friction MCP server require authentication?

No. We connected to Friction without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the Friction MCP server still maintained?

Friction is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
