## Overview

**Grade E · 43.8/100 · rank #1225 of 1486 · #13 in Diagramming · not agent-ready · confidence medium**


## Assessment

Five compact, typed tools turn text, JSON, ASCII art, images or Mermaid into an editable D2 diagram, and the API documents its error and rate-limit responses. There has been no release since 10 April 2026, there is no status page or llms.txt, and the API key opens the whole account with no scopes.

## Score breakdown (methodology v0.7, October 2026 research run)

Assessed 2026-11-06 from public evidence against the published checklist (https://www.anchorterminal.com/benchmark/#checklist). Confidence: medium. Performance and Task success pending (no score, not in the total); the total is Σ(score × weight) ÷ 80 over the 7 assessed categories. "This run" is each category's share of the 100 points.

| Category | Weight | This run | Score (0–100) | Points |
| --- | --- | --- | --- | --- |
| Reliability | 16% | 20 | 30 | 6.0 |
| Performance | 10% | pending | pending | n/a |
| Schema & documentation | 13% | 16.2 | 75 | 12.2 |
| Agent ergonomics | 13% | 16.2 | 66 | 10.7 |
| Security & auth | 14% | 17.5 | 45 | 7.9 |
| Payments & pricing | 10% | 12.5 | 20 | 2.5 |
| Task success | 10% | pending | pending | n/a |
| Maintenance & community | 7% | 8.8 | 17 | 1.5 |
| Transparency & trust (editorial 28, provenance 42) | 7% | 8.8 | 35 | 3.1 |
| Negative events | up to −15 | up to −15 | none recorded | 0 |
| **Total** | | | | **43.8 → E** |

### Why each score

- Reliability 30 (checked 2026-11-06): Hosted lines, because every tool call is generated on the AI Diagram Maker service, through the hosted endpoint or the npx server. No status page found on the site or in the README (0). No readable incident history (5). The only rate-limit number is the example in the OpenAPI 429 schema ('Maximum 100 requests per day exceeded.'), which isn't stated as the limit (5 of 15). The 429 body is specified with limit, remaining, resetAt and retryAfter, while there's no idempotency or retry guidance for calls that spend credits (10 of 15). No SLA found (0). Nothing labels the service or server beta (10). 0 + 5 + 5 + 10 + 0 + 10 = 30.
- Performance: Pending. Latency is measured per call by our probes, which haven't run yet, so this run doesn't score it. Its weight is shared across the assessed categories until the first probe window closes.
- Schema & documentation 75 (checked 2026-11-06): All five tools have zod input schemas in src/tools, and the repository ships an OpenAPI 3 file for POST /api/v2/diagrams/generate (25). No llms.txt (404) and no docs site for agents beyond the README (0). Each description says what the tool does and when to use it, listing trigger phrases and the diagram types, without saying when another tool fits better (16 of 20). `content` has a minimum length and `diagramType` an eight-value enum; the OpenAPI adds `inputType` and `format` enums (13 of 15). Examples in the parameter descriptions and README, and the OpenAPI documents 400, 401, 402, 422 (D2 failed to compile) and 429 with typed error bodies (13 of 15). Git tags from v1.1.1 to v3.0.8 and a /api/v2 path, with no changelog or release notes (8 of 15). 25 + 0 + 16 + 13 + 13 + 8 = 75.
- Agent ergonomics 66 (checked 2026-11-06): Five compact tools (25). Output can be SVG or PNG and the API can return the D2 source with `debug`, but there's nothing to page or trim, and results carry the rendered image (10 of 20). Typed error bodies with codes, a 422 that returns the failing D2 code, and retryAfter on 429 (16 of 20). No readOnlyHint or other annotations in the source and no idempotency key, and every call spends credits (5 of 20). Only `content` is required and the hosted endpoint needs no install, but there is no SDK beyond the server (10 of 15). 25 + 10 + 16 + 5 + 10 = 66.
- Security & auth 45 (checked 2026-11-06): Several named API keys per account, shown once and deactivated or deleted in Settings with a confirmation step, sent in a header, never a query string. No scopes, and the user guide says anyone with a key can access the account (20 of 30). The tools only create diagrams and can't change or delete anything in the account, but there's no read-only key (12 of 20). Tools return diagrams built from the caller's own input. Image inputs can be any public URL (10 of 15). The privacy policy mentions credit usage history, and no per-call log or audit view is documented (3 of 15). No security.txt, disclosure policy, bug bounty or certification found (0). 20 + 12 + 10 + 3 + 0 = 45.
- Payments & pricing 20 (checked 2026-11-06): No x402, MPP or L402 (0). Plan prices are public (Plus $10, Max $20 a month), with credits counted at 1,000 tokens each, so there's no per-diagram price (10 of 20). Basic is free forever with 50 credits a month, but the page doesn't say whether a card is needed or whether API and MCP calls are included (10 of 20, half as with an unstated card rule). A person signs up in the app and creates the key (0). 0 + 10 + 10 + 0 = 20.
- Task success: Pending. Task success needs the category task suites run through each tool, which haven't run yet, so this run doesn't score it. Its weight is shared across the assessed categories until then. A data provider's data-quality score is published on its listing now and becomes half of this category when it's scored.
- Maintenance & community 17 (checked 2026-11-06): Last release v3.0.8, published to npm on 10 April 2026, 210 days before this check (0). No release since 8 August (0). Four issues in all. The two open ones, from 4 May (hosted MCP credit usage) and 13 October 2026, show no reply, and one closed issue had a comment (5 of 25). In the official MCP registry under the GitHub-verified namespace io.github.erajasekar, but the entry is 1.0.0 from 19 March 2026 while npm is on 3.0.8 (10 of 15). The only workflow publishes to the registry. No tests or CI, and the MCP SDK floor is ^1.9.0 (2 of 10). 0 + 0 + 5 + 10 + 2 = 17.
- Transparency & trust 35 (checked 2026-11-06): The MCP server is MIT (package.json and LICENSE, added 18 March 2026). The service is closed, under terms last updated 24 September 2025 that name the operator only as AI Diagram Maker (20 of 30). The privacy policy of the same date keeps diagrams, revisions and chat prompts and responses 'as long as necessary', and the terms license user input 'to provide and improve our services', with no retention periods and no word on model training or the AI providers used (8 of 30). No deprecation policy or dated notices (0). No subprocessors or data locations named (0). The MCP server's source sends no telemetry of its own. 20 + 8 + 0 + 0 = 28.

Fix list, everything this grade says the listing lacks, the biggest gain first (18 items). What it covers is at https://www.anchorterminal.com/fixes/ai-diagram-maker-mcp.md (JSON https://www.anchorterminal.com/fixes/ai-diagram-maker-mcp.json). The whole list for a coding agent comes from `POST https://www.anchorterminal.com/api/v1/fix-list` with `{"listing": "ai-diagram-maker-mcp", "plan": "read"}`, free while the beta runs

### What we couldn't check

- Which plans include API and MCP calls, and how many credits a diagram costs: neither is stated on the pricing or MCP pages.
- The rate limit: only an example of 100 requests a day appears in the OpenAPI schema.
- unchecked: the repository's star count, because the GitHub API answered with its rate limit during this check.
- Who operates the service: the terms name only AI Diagram Maker; the npm author is Rajasekar Elango.

## Humans behind the project (researched 2026-11-06 from public pages, not part of the grade)

### Key people

- Rajasekar Elango, Author of the MCP server package. GitHub: https://github.com/erajasekar
- Note: The terms and privacy policy (24 September 2025) name the operator only as AI Diagram Maker, with no company form, address or person. The npm package ai-diagram-maker-mcp names Rajasekar Elango as author, with the npm maintainer account aidiagrammaker using an aidiagrammaker.com address, and the repository sits under the GitHub account erajasekar. No page calls him a founder, so the role is given as the package's author. Investors were looked for on the site, the terms, the privacy policy and the repository; none is mentioned, and no outside search was made for a one-person product with no company named. Rechecked on 6 November 2026 for a founder. The home page, blog index and sitemap name no founder or team, /about and /about-us return 404, and Rajasekar Elango's GitHub profile and personal site erajasekar.com don't mention AI Diagram Maker, so he stays unmarked as founder.

Across all listings: https://www.anchorterminal.com/prices/index.md

## Strengths

- Five tools with zod schemas, a diagramType enum and descriptions that say when to use each
- OpenAPI 3 file for the generate endpoint with documented 402, 422 and 429 responses
- A 429 body gives limit, remaining, resetAt and retryAfter
- Hosted endpoint with nothing to install, or a local npx server
- Output stays editable as D2 in the app and exports to SVG, PNG or Mermaid

## Weaknesses

- Last release 3.0.8 on 10 April 2026, and the registry entry still says 1.0.0
- No status page, SLA, llms.txt, changelog or security policy found
- API keys have no scopes and give full account access
- Plans don't say whether API and MCP calls are included, and an open issue asks how hosted MCP credits are counted
- The privacy policy names no AI model providers or other processors



## Before you call it (notes for agents)

1. Send the key in the `X-ADM-API-Key` header to https://mcp.aidiagrammaker.com/mcp, never in the URL
2. Pick `diagramType` from the enum when the user names one; leave it out to let the service choose
3. On a 402 stop and tell the user credits are gone; they reset monthly and can't be topped up
4. On a 429 wait for `retryAfter` seconds before the next call
5. Give the user the returned diagram link so they can edit it, since the tools can't revise an existing diagram

## Connect

Install:

```bash
ADM_API_KEY=your_api_key npx ai-diagram-maker-mcp@latest

## Verify this listing

For the vendor. The badge or a plain link to this page verifies the listing, from a page on aidiagrammaker.com or one of its subdomains, or the README at the root of github.com/erajasekar/ai-diagram-maker-mcp. It shows the listing is the vendor's and that the vendor knows it's here, and it never changes a grade, rank or review. The vendor sends the page's address to `POST https://www.anchorterminal.com/api/v1/verify` as `{"slug": "ai-diagram-maker-mcp", "url": "…"}`, or calls the `verify_listing` tool at https://www.anchorterminal.com/mcp. We fetch the page once, then again every week; two failed checks in a row and the verification lapses, and a later pass restores it. What we check: https://www.anchorterminal.com/builders/index.md#verify
