## 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**: 46/100
  - 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 5 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 enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement.
  - 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**: 81/100
  - 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 771 tokens (~96/item across 8 items; 5 tools + 3 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**: 71/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 0% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 75/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - 0 of 1 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "call_operation" implies "execute" and declares no destructiveHint at all, which the MCP spec reads as destructive by default.
  - An AI judge read all 7 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.

## MCP tools (5)

### `search_endpoints` (~91 tokens)

Canonical API selection tool for endpoint discovery and ranking.

Use this first to get the top recommended operations for a user intent.
Supports optional constraints plus tag-scoped selection via preferredTags,
excludedTags, or a curated tagPack key.

Input parameters:

- `constraints`
- `excludedTags`
- `limit`
- `preferredTags`
- `query` (string, required)
- `tagPack`

### `list_tag_packs` (~32 tokens)

List curated tag packs for large tool catalogs.

Use this to narrow exploration (for example social-media or enrichment).

### `list_all_endpoints` (~43 tokens)

List available Descovo API endpoints with optional tag/search filtering.

Input parameters:

- `limit`
- `search`
- `tagPack`
- `tags`

### `get_endpoint_details_full` (~86 tokens)

Get COMPLETE schema and details for a specific API operation.

Use this BEFORE calling an API to understand exactly what parameters are needed.

Args:
    operationId: The operation ID (e.g., "syncContactEnrichment")

Returns:
    Complete schema including all required/optional fields, request body schema,
    response schema, and example usage.

Input parameters:

- `operationId` (string, required)

### `call_operation` (~140 tokens)

Execute any Descovo API operation by operationId.

IMPORTANT:
\- apiKey is NOT required in the body if the MCP client sends an x-api-key header (most configs do). The backend auto-injects it.
\- Prefer search_endpoints() first when operation choice is ambiguous.
\- Use get_endpoint_details_full(operationId='...') first for complex/nested parameter shapes.

Args:
    operationId: The operation ID to call
    params: Parameters dict: {"body": {...}, "path": {...}, "query": {...}}

Returns:
    API response data or error details.

Input parameters:

- `operationId` (string, required)
- `params`

## Common questions

### What is the Descovo — B2B contact data MCP server?

Descovo — B2B contact data is an MCP server listed in the public MCP registry as com.descovo/descovo. B2B contact data for AI agents: search 700M+ people, reveal work emails. Pay per record. This page covers its hosted endpoint (https://mcp.descovo.com/mcp).

### Is the Descovo — B2B contact data MCP server safe to use?

Descovo — B2B contact data scores 60 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 Descovo — B2B contact data MCP server expose?

Descovo — B2B contact data exposes 5 tools: search_endpoints, list_tag_packs, list_all_endpoints, get_endpoint_details_full, call_operation. Their descriptions and schemas cost roughly 392 tokens of context every time the server is loaded.

### Does the Descovo — B2B contact data MCP server require authentication?

No. We connected to Descovo — B2B contact data without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the Descovo — B2B contact data MCP server still maintained?

Descovo — B2B contact data 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 Descovo — B2B contact data MCP server?

VerifyMCP ran 11 checks on Descovo — B2B contact data, covering TLS certificate, HSTS header, DNSSEC, Transport and 7 more. 2 items could not be completed, a gap on our side rather than a finding about Descovo — B2B contact data: Authorization and HTTPS. 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.
