## 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 2026-10-22.

- **Endpoint Security**: 57/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 4 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - 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**: 75/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 419 tokens (~104/item across 4 items; 4 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 23/100
  - Stability observed for 7 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 90/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 71% 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 4 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 5 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.

## Install

### How do I install the mcpcost MCP server?

mcpcost is a hosted endpoint at https://mcpcost.ulehla.dev/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 (4)

### `lookup_server` (~71 tokens)

Look up a registry server

Latest probe of one server from the official MCP registry: status, protocol, tool count, exact token cost of its tool definitions in Claude, latency. Accepts the registry name (io.github.owner/name) or the server URL.

Input parameters:

- `nameOrUrl` (string, required): Registry name or https URL of the server

### `search_servers` (~127 tokens)

Search the registry board

Find servers by words in name, title, description or host, with optional filters, sorted by exact Claude token cost by default. Returns up to 20 servers per page; page numbers go to 20, after that pass the `next` cursor from the previous answer.

Input parameters:

- `cursor` (string): The `next` value of a previous answer, to continue from there
- `page` (integer)
- `query` (string): Words to match, three or more characters each
- `sort` (string)
- `status` (string): ok = answers and lists tools

### `check_server` (~83 tokens)

Probe a server live

Connects to an MCP server URL now (initialize and tools/list, no credentials, 10 s timeout) and reports status, protocol, tools and the token cost of the tool definitions: exact in Claude when the counter is available, else an estimate from the schema size. For registry servers prefer lookup_server.

Input parameters:

- `url` (string, required): https URL of the MCP endpoint

### `registry_summary` (~33 tokens)

Registry summary

Aggregates of the latest daily run: how many servers answer, token cost percentiles, protocol versions, heaviest servers.

## Common questions

### What is the mcpcost MCP server?

mcpcost is an MCP server listed in the public MCP registry as io.github.ondraulehla/mcpcost. Health and token cost of every remote MCP registry server, probed daily. Look up, search, or probe. This page covers its hosted endpoint (https://mcpcost.ulehla.dev/mcp).

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

mcpcost scores 67 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 mcpcost MCP server expose?

mcpcost exposes 4 tools: lookup_server, search_servers, check_server, registry_summary. Their descriptions and schemas cost roughly 314 tokens of context every time the server is loaded.

### Does the mcpcost MCP server require authentication?

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

### Is the mcpcost MCP server still maintained?

mcpcost is still listed as active in the MCP registry. We last reached this channel on 22 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
