Why the edge

Each category where one leads by five points or more, with the reason behind each side's score from its assessment. The numbers are in the table below; this is what they stand for.

Maintenance & community Context7 +20

amCharts 5 MCP Server 75

v1.9.4 on 25 October 2026 (30). Eight releases since 8 October (20). Issues not read (0). Official registry entry io.github.amcharts/amcharts5 (15). CI with test and deploy workflows (10). 30 + 20 + 0 + 15 + 10 = 75. 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.

Context7 95

@upstash/context7-mcp 4.4.4 on 19 October 2026, and ctx7 0.8.2 and @upstash/context7-sdk 0.6.0 on 23 October (30). Twenty MCP releases between 7 August and 19 October, from 4.0.0 to 4.4.4 (20). 28 open issues and pull requests merging most days, per the 1 October check, not re-read on 1 November as GitHub's pages weren't reachable. Commits land most days in the repository, the latest on 30 October (20). Listed in the official MCP registry as io.github.upstash/context7, latest 4.4.4 published 19 October (15). Dependabot, a test workflow on every push and pull request, and current dependencies (MCP server SDK 2.3.1 since 4.4.3) (10). 30 + 20 + 20 + 15 + 10 = 95.

Security & auth Context7 +19

amCharts 5 MCP Server 50

No credential, so nothing to leak, scope or revoke, as the checkatrade listing reads it (15 of 30). Read-only tools (20). Returns amCharts' own docs (10). No audit log (0). No security programme found (5 of 20). 15 + 20 + 10 + 0 + 5 = 50.

Context7 69

API keys with the ctx7sk prefix, hashed at rest and rotatable from the dashboard, and OAuth at /mcp/oauth backed by Clerk, plus enterprise-managed auth. The hosted transport checks OAuth access tokens strictly (signature, issuer, type, expiry and audience) and verifies Entra token signatures. No per-key scopes on the documentation server. A separate Admin MCP (admin.mcp.context7.com) needs a key with management access turned on, per its README (22). Every documentation tool is read-only, so there's nothing destructive to confirm. Enterprise can restrict which libraries and source types a team can reach (15). Indexed documentation is third-party content. Context7 documents a two-pass prompt-injection and malware classifier on indexed content, which we can't test (12). Usage shows in the dashboard, and on-premise Enterprise adds an access audit log (8). SECURITY.md with private reporting and a 48-hour acknowledgement target, SOC 2 Type II through Upstash, no bug bounty found, no published advisories, and the supported-versions table still lists only 1.0.x while 4.4.4 ships, re-read in the clone on 1 November (12). 22 + 15 + 12 + 8 + 12 = 69.

Transparency & trust Context7 +11

amCharts 5 MCP Server 57

MIT licence, copyright 2026 amCharts (30). Public docs only, no user data (20 of 30). Dated changelog, no deprecation policy (8 of 20). Hosted on Cloudflare per the repository's wrangler config; no data locations stated (8 of 20). 30 + 20 + 8 + 8 = 66.

Context7 68

The MCP server, CLI and SDK are MIT. The index and API behind them are closed, under Upstash's terms (25). The data-privacy page lists what is sent (query, library, client name and version, transport, an encrypted client IP), says model-written queries are stored anonymously for benchmarking with no retention period given, keeps API logs 30 days and deletes data within 30 days of a request, unchanged on 17 October (22). No deprecation policy. Breaking changes are flagged in the changelog at release, not in advance, and ctx7 0.8.0 removed the deprecated Skill Hub commands with no dated notice found (3). Reranking subprocessors named (OpenAI, Google Gemini, Anthropic) and storage in the US and EU stated. The client analytics headers are disclosed, with no opt-out in the server (15). 25 + 22 + 3 + 15 = 65.

Agent ergonomics Context7 +5

amCharts 5 MCP Server 70

12 tools, about 12 KB (15). Tools fetch one document or example at a time (15 of 20). Errors not documented (5 of 20). All 12 annotated read-only (20). No key and one URL; mcp-remote for stdio clients (15). 15 + 15 + 5 + 20 + 15 = 70.

Context7 75

Two tools. The hosted tools/list response on 1 November came to 5,262 characters of JSON, most of it one description, plus the server instructions sent at initialisation. Since 4.4.3 the list answers carry a one-hour cache lifetime on the 2026-07-28 protocol (20 of 25). Version 2.0.0 removed page, limit and the token budget, so there's no output-size control beyond writing a narrow query. The language argument ranks examples and doesn't bound size (5). Errors are readable and say what to do (a 429 names the dashboard or plans page, a 404 says to re-run resolve-library-id, a 401 names the ctx7sk key prefix). query-docs sets isError on failure since 4.2.1, and since 4.4.3 (19 October) resolve-library-id does too when the search fails, while a search with no matches stays a normal result (20). Both tools carry readOnlyHint: true, destructiveHint: false and idempotentHint: true, read from the hosted endpoint on 1 November (20). Two required parameters per tool and one optional. A server-side shim rewrites common hallucinated argument names. The SDK is TypeScript only, plus a REST API (10). 20 + 5 + 20 + 20 + 10 = 75.

How the scores have moved

Verdicts

amCharts 5 MCP Server

amCharts' MCP server is a model docs server, open source, free, keyless, 12 read-only annotated tools that fetch only the page or example needed, with a dated changelog and CI. It's narrow by design, useful only when an agent writes amCharts 5 code.

Context7

Two read-only tools that fetch current library documentation, both annotated and both flagging failures with isError since 4.4.3. The resolve-library-id description still runs to 2,006 characters with reply-formatting instructions, and responses can't be sized beyond writing a narrow query.

Before you call either

amCharts 5 MCP Server

  1. Fetch the specific doc or example rather than searching broadly
  2. Check the amCharts licence before shipping charts commercially
  3. Use mcp-remote for clients that only run stdio servers

Context7

  1. Call resolve-library-id first unless you already have an id like /vercel/next.js; query-docs answers a bare name with a not-found message
  2. Ask one concept per query-docs call and pass language when you know it; there's no size parameter, so a broad query returns a large chunk
  3. Check isError on both tools. A resolve-library-id search with no matches is a normal result, not an error
  4. Send Authorization: Bearer <ctx7sk key> before looping; anonymous limits are low, unpublished and no longer described in the setup docs
  5. Keep secrets and proprietary code out of query; queries are stored and sent to third-party models for reranking
