## 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**: 74/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Nothing on it is marked destructive, but we can't show that an anonymous caller can only read: full credit needs the server to list at least one tool and every tool to be verifiably read-only. We use a best-effort check of tool names and descriptions to tell read-only tools from tools that change things, so some genuinely read-only tools may not get full credit. Names that start with a read verb (get, list, read, search and similar) and accurate readOnlyHint annotations help. Meet that to earn full credit, or require authorisation.
  - 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**: 58/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 299 tokens (~299/item across 1 items; 1 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 3/100
  - Stability observed for 1 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 1 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 2 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 RealMarket E-Signature Cost MCP server?

RealMarket E-Signature Cost is a hosted endpoint at https://tools.realmarketlabs.com/mcp/esign-cost, 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.

### `compare_esignature_costs` (~200 tokens)

Compare e-signature costs

Calculates the current cost per signed document and per year, and compares it with the public prices of other e-signature providers for the same volume, in Brazilian reais. Also notes per-user licensing and the contract renewal window.

Input parameters:

- `confirm_unusual_cost` (boolean): Set true only after the user confirms a cost per document that the tool flagged as unusually high.
- `contract_renewal` (string, required): When the current contract renews.
- `current_provider` (string, required): E-signature tool used today; 'none' if not using one yet.
- `documents_per_month` (integer, required): Documents sent per month.
- `monthly_cost_brl` (number, required): What the company pays per month today, in BRL (0 if none).
- `senders` (integer, required): People who send documents for signature.
- `who_sends` (string, required): Who sends: people on the team, an integrated system (API), or both.

## Common questions

### What is the RealMarket E-Signature Cost MCP server?

RealMarket E-Signature Cost is an MCP server listed in the public MCP registry as com.realmarketlabs.tools/esign-cost. Compare e-signature costs per document and per year in Brazil (BRL) across providers. This page covers its hosted endpoint (https://tools.realmarketlabs.com/mcp/esign-cost).

### Is the RealMarket E-Signature Cost MCP server safe to use?

RealMarket E-Signature Cost scores 68 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 RealMarket E-Signature Cost MCP server expose?

RealMarket E-Signature Cost exposes 1 tool: compare_esignature_costs. Their descriptions and schemas cost roughly 200 tokens of context every time the server is loaded.

### Does the RealMarket E-Signature Cost MCP server require authentication?

No. We connected to RealMarket E-Signature Cost without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the RealMarket E-Signature Cost MCP server still maintained?

RealMarket E-Signature Cost 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.

### What did VerifyMCP test on the RealMarket E-Signature Cost MCP server?

VerifyMCP ran 13 checks on RealMarket E-Signature Cost, covering TLS certificate, Authorization, HTTPS, HSTS header and 9 more. 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.
