Liner Search MCP vs SerpApi

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.

SerpApi 84

The API is closed under one terms-and-privacy page, and the MCP server is MIT (18). The legal page and the security page agree that search data is deleted after 31 days, ZeroTrace mode (an enterprise parameter) stores nothing, and a DPA is available on request (26). Deprecations show up as dated release notes, such as eBay's Sold and Completed filters on 28 September 2026, but there's no notice policy, and the terms allow termination without notice (8). Named subprocessors (AWS, Cloudflare, Wasabi, Stripe, Intercom and others) and US hosting with Standard Contractual Clauses (18).

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.

SerpApi 82

Release notes carry dated entries almost daily, the latest on 2 November 2026, and serpapi-python 1.2.0 shipped on 30 October (30). Since 4 August, serpapi-python 1.1.0, 1.1.1, 1.1.2 and 1.2.0, MCP server 1.0.3 and 2.0.0, and serpapi-cli 0.3.0, 0.4.0 and 0.5.0, besides the release notes (20). Release notes run several entries a week and the MCP repo merged a fix on 27 October. Open issues weren't read, since GitHub's pages refuse our reader (12). The MCP server is in the official registry as io.github.serpapi/serpapi-mcp and the Python SDK and CLI are current, but the JavaScript SDK's last release is still 2.2.1 of 26 July 2025 (12). The MCP, Python and CLI repositories run tests in CI; pass state not read (8).

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.

SerpApi 88

json_restrictor selects fields, output=md returns Markdown (the MCP README claims 50 per cent fewer tokens on average) and the MCP compact mode drops metadata. One core MCP tool plus two opt-in UI tools (22). start, num, location, language and engine-specific filters, plus async with the Search Archive API (20). Documented status codes and search_metadata.status values, though one 429 covers both the hourly limit and an empty balance (14). Searches are read-only, failed and cached searches aren't billed, and the MCP tool sets readOnlyHint true and destructiveHint false (18). Only q is required for most engines. llms.txt lists libraries in 11 languages, though the JavaScript one hasn't had a release since July 2025 (14).

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.

SerpApi 67

No OpenAPI or similar spec for the REST API. The MCP server publishes per-engine parameter lists as resources (serpapi://engines/<engine>), which we count as a partial contract (10). llms.txt, pricing.md and Markdown twins of the docs pages, such as search-api.md (10). Each engine page describes every parameter, and the MCP tool says when to use it but not when not to (14). Parameters list allowed values on the engine pages, but the MCP search tool takes one free-form params object (7). Examples on every engine page, and a status-and-errors page documents 400, 401, 403, 404, 410, 429 and 5xx with a JSON error field (14). Dated release notes with several entries a week, though the API itself isn't versioned (12).

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.

SerpApi 65

Atlassian Statuspage at status.serpapi.com, with per-API components and incident history on its history pages and Atom feed (20). Between 4 August and 2 November the history lists 35 incidents active in the window. Two were wide failures that also list the general API component, each over an hour. From 7 to 9 August an outage across 37 Google and Google Light APIs, including Search, left 'a large number of requests' failing or timing out. On 10 September the vendor posted a 'service outage across all of our APIs', with degradation until 17 September. From 6 October a degradation of 15 Google and Google Light APIs, including Search, which the vendor called a 'partial service outage affecting multiple APIs', was still open on 2 November. Like the single-engine incidents, it hit part of the product and counts as minor. Two majors (5). Hourly throughput published per plan, 50 an hour free to 640,000 on Cloud 54M (15). 429 is documented as either the hourly limit or an empty search balance, with no Retry-After or backoff guidance found (5). The terms (updated 27 August 2026) promise a 99.95% SLA on all plans with credits up to 100% (10). GA (10). 20 + 5 + 15 + 5 + 10 + 10 = 65.

Liner Search MCP 20

No machine payment protocol (0). Per-call prices public (20). No free tier found (0). A person signs up in a browser for OAuth or an API key (0). 0 + 20 + 0 + 0 = 20.

SerpApi 30

No x402, MPP or L402 on the pricing page or llms.txt (0). Monthly plans are public with search counts, but there's no pay-per-search option (10). Free plan of 250 searches a month, no card (20). An account needs a browser signup (0).
