Liner Search MCP vs NewsCatcher

Liner Search MCP 45

Tool schemas not read without sign-in (15 of 25). llms.txt (10). A table says which tool fits which need, and that the domain tools return the same shape as search_web (12 of 20). Inputs not verifiable (3 of 15). Setup examples, no error responses (5 of 15). Registry version 1.0.0 since 11 September; no changelog found (0). 15 + 10 + 12 + 3 + 5 + 0 = 45.

NewsCatcher 94

OpenAPI 3.1 for the News API (version 1.3.9, 4 paths) and the agent (version 1.5.1, 33 paths), linked from llms.txt, and typed JSON Schema on every MCP tool through Pydantic (25). llms.txt, a Markdown copy of every page and a docs MCP server (10). MCP tool descriptions say when to use each and which tool to use instead, such as list_articles for older news; the REST reference explains each endpoint and the 'Choose an API' page compares them (17 of 20). Inputs are typed with enums for effort, mode and dimensions, length and range limits such as a 500-character query and limit 1 to 100, and required fields marked (13 of 15). Runnable examples in curl, Python and JavaScript, and an error table with retry advice for every status. The agent spec carries no response examples (14 of 15). Versioned APIs with a dated changelog, the latest entries on 4 November 2026, and separate changelogs for the v3 News API and CatchAll (15). 25 + 10 + 17 + 13 + 14 + 15 = 94.

Liner Search MCP 34

Terms and privacy linked from the docs but not read in this batch (5 of 30). Data handling not read (5 of 30). No deprecation policy found for the MCP server; the docs note older endpoints priced per version (5 of 20). Subprocessors not read (5 of 20). 5 + 5 + 5 + 5 = 20.

NewsCatcher 79

The API is closed under terms of 2 November 2026 naming NewsCatcher, Inc., and the MCP server is MIT, so between the two bands (20 of 30). The terms say inputs and generated data are not used to train models, a DPA applies automatically, and the privacy policy gives retention periods (server logs 7 days, API logs with query text 90 days, then archived indefinitely, billing records about seven years). They agree with each other, but indefinite archives of query logs hold it back (22 of 30). The terms promise 30 days' email notice before a paid product or API version is discontinued, with refunds of unused credits, and the v3 News API has a migration guide (15 of 20). A sub-processor list dated 2 November 2026 with each provider's location and the data it handles. The MCP repository deploys to Vercel and can send pseudonymised analytics to PostHog, and neither appears on the list (16 of 20). 20 + 22 + 15 + 16 = 73.

Liner Search MCP 45

Registry entry com.liner/search last updated 11 September 2026 (20). No dated changelog found (0). Support page linked from the docs (10 of 15). Official registry entry under its own namespace (15). No package to read (0). 20 + 0 + 10 + 15 + 0 = 45. Registry presence read from Anchor Terminal's own daily import of the official MCP registry (/api/v1/registry.json, 6 November 2026), not the registry's API.

NewsCatcher 76

Read for a closed service, with the MCP repository read as code. News API 1.1.0 and Agent 1.5.0 on 4 November 2026, MCP server 0.1.0 on 6 November and v3 News API 3.25.0 on 6 November (30). In the 90 days from 8 August, the 30 October launch, News API 1.1.0, Agent 1.5.0, MCP 0.1.0 and v3 releases 3.19.0 to 3.25.0 (20). Public dated changelogs, support by email and Pylon, and a security policy with a 3-business-day target. The MCP repository is a day old, so there are no issues to judge (10 of 15). The CatchAll MCP server is in the official registry under the verified namespace com.newscatcherapi, but the new server isn't, and no official SDK for the current API was found; the Enterprise APIs list libraries (8 of 15). The MCP repository runs its test suite in CI with a read-only token; pass state not read (8 of 10). 30 + 20 + 10 + 8 + 8 = 76.

Liner Search MCP 65

Nine tools (25). No paging or size controls documented (5 of 20). 429 codes documented for the API (8 of 20). All tools read; annotations not read (12 of 20). One URL with OAuth, few required inputs and an OpenAI-compatible API (15). 25 + 5 + 8 + 12 + 15 = 65.

NewsCatcher 84

15 MCP tools in four toolsets, chosen per connection with ?tools=, and tools return compact text rather than the full JSON. 15 for 11 to 30 tools plus 7 for toolsets (22 of 25). limit, search_window, effort, language, country, publisher, coverage and content-type filters, sorting, and paging on /articles; agent tables come back up to 200 rows at a time over MCP (20). Every status is documented with whether to retry; the agent returns stable code values, while the News API body has a status_code and a message meant for people (17 of 20). Every tool carries readOnlyHint and idempotentHint, writes carry destructiveHint, start_research has a free dry_run, and refused or failed calls aren't charged. No idempotency key for starting runs (17 of 20). Only q is required, with medium effort and a 7-day window as defaults. No official SDK for the current API was found; the docs show raw HTTP in three languages (8 of 15). 22 + 20 + 17 + 17 + 8 = 84.

Liner Search MCP 50

incident.io status page at status.liner.com with components for liner.com and app.liner.com only, none for the API or MCP (15). 100% uptime shown since August (20, no incidents shown). Rate limits published per API with numbers (Scholar Search 2 requests a second, agents 2 a second) (15). 429 with a code for concurrency limits, no Retry-After or backoff guidance found (0 of 15). No SLA found (0). Not labelled beta (0 of 10; 'limits may be adjusted over time', GA not stated). 15 + 20 + 15 + 0 + 0 + 0 = 50.

NewsCatcher 67

Read with the hosted lines, for the News API, the agent and the hosted MCP server. status.newscatcherapi.com (Hyperping) shows one News API component with 99.820% uptime from August to November 2026 and an incident history. The agent and the MCP server have no component of their own (20). In the 90 days from 8 August, one incident, on 1 September 2026, when the vendor wrote that for about four hours a higher-than-usual number of requests to the production News API timed out because of one client's queries. Read as one major (10). Rate limits published per plan, 1 request a second free and up to 10 on pay as you go, with exact limits from the free GET /subscription (15). 429 carries Retry-After with instructions to retry the same request, 503 carries Retry-After, and failed or refused requests are not charged. Agent runs and monitor creation have no idempotency keys (12 of 15). An uptime SLA exists only in signed Enterprise agreements; none is published (0). Generally available since 30 October 2026, with OAuth for the MCP server announced as coming soon (10). 20 + 10 + 15 + 12 + 0 + 10 = 67.

Liner Search MCP 35

OAuth 2.1 or an API key; scopes not published (20 of 30). All tools are reads (10 of 20). Results carry web pages and documents with no injection guidance (0). No audit log found (0). No security.txt (404) or security programme found (5 of 20). 20 + 10 + 0 + 0 + 5 = 35.

NewsCatcher 45

API keys in the x-api-key header, several per account, revocable in the platform, with advice to keep one per application. A 403 for 'a key that may not use this API' suggests per-key API access, but no scopes are documented (20). The MCP server documents ?apiKey= on the server URL for Claude.ai custom connectors, with a warning, so less 10 (10 of 30). The MCP repository's SECURITY.md says URL keys are rejected unless the operator enables them, which the hosted server does per the docs. Toolsets let an operator load only the read-only news tools, write tools carry destructiveHint, and the server tells the assistant to confirm large or hourly agent jobs (14 of 20). Results are third-party article text and summaries, and no prompt-injection guidance was found in the docs or the MCP server's instructions (0 of 15). Every response carries a Correlation-ID, GET /subscription shows usage and balance, and runs are listed in the platform. No per-call audit log for the customer was found (7 of 15). The security page and footer claim SOC 2 Type II and link a trust centre on Oneleet, which wasn't read. A vulnerability disclosure policy covers the MCP server. No security.txt (404) and no bug bounty found (14 of 20). 10 + 14 + 0 + 7 + 14 = 45.
