## Why the edge

### Maintenance & community: amCharts 5 MCP Server +62

- 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.
- Microsoft Learn MCP Server (13): The release notes, re-read on 4 November, still end at the plugin release on 23 March 2026, more than 180 days ago (0). The repository set @microsoft/learn-cli to 1.0.0 on 4 September 2026 (commit 90e1837), with no tag, release or changelog entry, so it isn't counted as a release. The plugin manifest is still 0.3.1 from 19 March 2026. No server entries in the last 90 days (0). Open issues per the 1 October check (eight, the oldest from June 2025; #100 got a documentation fix on 2 September 2026). Questions go to the GitHub repository (8). Registry line 15 to 0. The registry entry was read from the MCP registry's JSON API, a source Anchor Terminal no longer uses, and the repository carries no server.json, so no readable registry page shows the listing. The CLI has a vitest suite that the validation workflow runs on Node 22 and 24, Dependabot updates (the latest on 10 September 2026) and actions pinned to commit SHAs on 30 October. The server's own health isn't visible (5). 0 + 0 + 8 + 0 + 5 = 13.

### Reliability: amCharts 5 MCP Server +45

- amCharts 5 MCP Server (65): Local-software reading for an open-source server that amCharts also hosts. Installs as @amcharts/amcharts5-mcp, and the hosted URL needs nothing installed (20). test.yml runs on the repository; pass state not read (15 of 25). Repository issues not read (0). A dated CHANGELOG.md with semver releases (15). Version 1.9.4 (15). 20 + 15 + 0 + 15 + 15 = 65.
- Microsoft Learn MCP Server (20): Scored as a hosted MCP server. No status page for Microsoft Learn or this endpoint was found (0), so there's no readable incident history (5). The FAQ (dated 5 May 2026, re-read on 4 November) says the free endpoint has rate limits for fair use but gives no numbers, and the release notes and best-practices page give none either (0). Throttling and 429 behaviour aren't documented. The best-practices page says to refresh `tools/list` and retry after a 400 or 404, which is safe-retry guidance for tool changes, and every tool is a read (5, a partial kept). No SLA (0). Generally available since 7 November 2025 per the release notes (10). 0 + 5 + 0 + 5 + 0 + 10 = 20.

### Schema & documentation: amCharts 5 MCP Server +42

- amCharts 5 MCP Server (84): 12 tools read from tools/list with JSON Schema inputs (25). Docs served as Markdown to the agent (10). Descriptions say what each returns, and the docs explain the on-demand approach (16 of 20). Typed inputs with two enums (10 of 15). Worked examples in the README (8 of 15). Dated changelog (15). 25 + 10 + 16 + 10 + 8 + 15 = 84.
- Microsoft Learn MCP Server (42): Contract line 20 to 0. The server is closed source, Microsoft publishes no tool definitions because it treats them as dynamic, and the only typed parameters are in the README's tool table. A parameter table isn't a published JSON Schema (read-ai, zapier-mcp), and calling the server's `tools/list` would be a request to the product's own endpoint, which this check doesn't make. No llms.txt found, but learn.microsoft.com returns the docs pages as Markdown when asked with `Accept: text/markdown` (the release notes, read that way on 4 November), as for copilot-studio-mcp, azure-devops-mcp and dynamics-365-sales, and the README is Markdown (10, was 5). The README table gives one line of purpose per tool, and the repository's three agent skills and a suggested system prompt say when to use each (12). Inputs are `query` and `url` strings plus an optional `language` string with no listed values (6). Configuration examples for about twenty clients and a troubleshooting table. No documented error responses beyond 405 (6). A release-notes page with seven dated entries, the last on 23 March 2026. Microsoft says the tool surface is dynamic and not versioned (8). 0 + 10 + 12 + 6 + 6 + 8 = 42.

### Agent ergonomics: amCharts 5 MCP Server +12

- 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.
- Microsoft Learn MCP Server (58): Three tools, which the README describes in one line each. We couldn't measure the live definitions (25). `maxTokenBudget` on the endpoint URL truncates search results to a token budget. `microsoft_docs_fetch` always returns the whole page and nothing pages (10). Errors aren't documented beyond the 400 or 404 refresh rule and a 405 for browsers (5). Every tool is a read and safe to repeat. We couldn't check whether `readOnlyHint` is set (8). One required parameter per tool and no auth. A CLI on npm, no SDKs (10).

### Security & auth: Microsoft Learn MCP Server +10

- 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.
- Microsoft Learn MCP Server (60): No credentials at all, so nothing to leak or scope (20). All three tools are reads (15). Results come from Microsoft's own documentation and code samples, which the README says is the only source (10). No per-call visibility for the caller, since there's no account (0). MSRC reporting with a 24-hour response target in SECURITY.md and Microsoft's bug bounty programme. microsoft.com's security.txt was past its Expires date per the 30 September check (15).

## 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.

**Microsoft Learn MCP Server.** Access requires no account, key or card, and the three tools are all reads. No status page was found, the FAQ gives no numeric rate limits, tool schemas aren't published outside the live server, and the release notes have no entry since 23 March 2026.

## 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

### Microsoft Learn MCP Server

1. Append `?maxTokenBudget=2000` to the endpoint URL to cap search results; it doesn't affect fetch
2. Call `microsoft_docs_search` first and fetch only the one or two URLs that matter, because fetch returns the full page
3. Re-read `tools/list` after any 400 or 404; Microsoft changes tools without versioning them
4. Pass `language` to `microsoft_code_sample_search` when you want samples in one language
