Category Data and Analytics
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. How we score → Why this is hard to score →
Endpoint Security83
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- 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. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC is configured correctly; the domain's records validate against the full chain to the root. View diagnostics → Pass
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability78
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 1384 tokens (~138/item across 10 items; 7 tools + 3 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management20
- Stability observed for 6 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage95
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 86% of tool parameters carry a description.Partial
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 7 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 9 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass

No change was recorded against any check on this day. Stability & Change Management went from 3 to 7. That category is still filling its 30-day observation window: 1 days of observed history at the previous scan, 2 at this one. The score rises as the window fills, whether or not the server changes.

The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
assess_master_data_quality Assess Master Data Quality ~197

| domain | string | yes | Reference-data domain identifier, as get_master_data_schema names it. |
| include_inactive | boolean | – | Whether values not KNOWN to be active at valid_at are served. False excludes them; true serves them flagged - active: false for a value declared inactive, beside the reference_value_inactive warning,… |
| limit | integer | – | Page size, applied after query, codes, and validity have narrowed the list. |
| locale | string | – | Language tag echoed on every served value and in the answer. Labels are served exactly as the snapshot stores them; there is no translation layer. |
| query | string | – | Optional code or label search: a case-insensitive substring match against a value's code OR its label. Omit it to match every value. |
| valid_at | string | – | The instant to evaluate each value's validity interval at. Defaults to the request clock. A value whose source DECLARES its interval is active when valid_from <= valid_at < valid_to, an absent or nul… |

How do I install the Agent Master Data MCP server?
Agent Master Data is a hosted endpoint at https://api.agentmasterdata.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.

What is the Agent Master Data MCP server?
Agent Master Data is an MCP server listed in the public MCP registry as com.agentmasterdata/agent-master-data. Paid x402 API and MCP for trusted public master data, golden records, and reference data. This page covers its hosted endpoint (https://api.agentmasterdata.com/mcp).
Is the Agent Master Data MCP server safe to use?
Agent Master Data scores 78 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 Agent Master Data MCP server expose?
Agent Master Data exposes 7 tools: get_master_data_schema, search_master_data, resolve_master_data_entity, get_master_data_golden_record, get_master_data_relationships, and 2 more. Their descriptions and schemas cost roughly 1,198 tokens of context every time the server is loaded.
Does the Agent Master Data MCP server require authentication?
No. We connected to Agent Master Data without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.
Is the Agent Master Data MCP server still maintained?
Agent Master Data is still listed as active in the MCP registry. We last reached this channel on 6 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 Agent Master Data MCP server?
VerifyMCP ran 13 checks on Agent Master Data, 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.
