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.

Reliability Robolly +25

Contentdrips API and MCP 23

Hosted lines. No status page found on the site, the developer docs or the footers (0). No readable incident history (5). No rate limit is given in numbers, only monthly call allowances by plan (6,000 on Pro, 25,000 on Ultimate), which earn a little (5 of 15). The troubleshooting note says to check /queue/stats and retry after a short delay when rate limited, with no status code or Retry-After. Render jobs are asynchronous, so polling is safe (3 of 15). No SLA found (0). The MCP server is v1.0.0 and the render API is not labelled beta (10). 0 + 5 + 5 + 3 + 0 + 10 = 23.

Robolly 48

Hosted lines. The footer links an UptimeRobot status page, but it loads its figures from /api/, which stats.uptimerobot.com's robots.txt disallows, so the page showed no monitors or history (10 of 20 for a page that exists) and no history was read (5). A hard limit of 3 renders a second is published (15). The rate-limit error code and advice to send renders one at a time, and identical renders are cached for 45 days at no cost, which makes a retry safe; there's no Retry-After or backoff interval (8 of 15). No SLA found (0). The API isn't labelled beta (10). 10 + 5 + 15 + 8 + 0 + 10 = 48.

Agent ergonomics Robolly +21

Contentdrips API and MCP 54

29 MCP tools (15 for 11 to 30), with no toolsets or read-only subset (15 of 25). list_posts filters by status and get_my_templates by type and workspace, and no pagination is documented (8 of 20). Errors carry error and message, and the troubleshooting section explains template-not-found and label mismatches (12 of 20). Access labels in the docs, confirmed: true on publish_post, and job polling that is safe to repeat, but no idempotency key on renders or post creation, and the labels couldn't be confirmed as MCP annotations (12 of 20). Two required fields to render (template_id, output), and no SDK beyond an Embed SDK for the editor (7 of 15). 15 + 8 + 12 + 12 + 7 = 54.

Robolly 75

Nine MCP tools (25). The renders list pages with a cursor, and templates are found by name (14 of 20). Errors carry errorCode and developerMessage with eight documented codes (17 of 20). Identical renders are cached for 45 days, so repeats are free and safe, the MCP server has no delete tool, and annotations couldn't be read on the closed server (12 of 20). Renders return the file synchronously by default, but there's no SDK (7 of 15). 25 + 14 + 17 + 12 + 7 = 75.

Security & auth Robolly +16

Contentdrips API and MCP 31

API keys from the dashboard, with no scopes, expiry or rotation documented. The MCP server also runs OAuth 2.0 with PKCE and dynamic client registration, but its one mcp scope authorises the same full key (18 of 30). No read-only key or endpoint. publish_post needs confirmed: true and the docs ask for confirmation before deletes (10 of 20). Tools read blog, YouTube and TikTok links and download external images, and no prompt-injection guidance was found (3 of 15). No audit log or per-call record documented (0). No security.txt, disclosure policy, bug bounty or certification found (0). 18 + 10 + 3 + 0 + 0 = 31.

Robolly 47

Bearer API key, signed render links, and MCP OAuth with one robolly:mcp scope limited to the organisation the user approves. Connections are listed and revoked under Connected AI Tools, and the API key is never shared with an OAuth client. No key scopes or rotation documented (22 of 30). The MCP server can create and update templates but not delete them; there's no read-only mode (10 of 20). Tools return the user's templates and public gallery designs (10 of 15). A renders list and the connected-tools view give some visibility, with no audit log documented (5 of 15). No security.txt (the path returns the site's HTML shell), disclosure policy, bug bounty or certification (0). 22 + 10 + 10 + 5 + 0 = 47.

Transparency & trust Contentdrips API and MCP +11

Contentdrips API and MCP 60

Closed service under terms of use dated 11 December 2024, governed by the laws of Pakistan (15). The privacy policy of 9 August 2026 states retention while the account is active, deletion of content as soon as the account is deleted apart from short-lived backups, deletion of social tokens on disconnect, and no training of Contentdrips' own models on user content (22 of 30). No deprecation policy. The legacy carousel input is 'still supported' with no end date (3 of 20). The policy names OpenAI, OpenRouter, Google Gemini and TinyPopups and has an international transfers section, without a full subprocessor list or hosting locations (12 of 20). 15 + 22 + 3 + 12 = 52.

Robolly 49

Closed service under terms effective 8 April 2026 from Avantis Innovations LLC in Wyoming. The terms can change without notice (15). The privacy policy of the same date covers Google sign-in and Sheets data, says spreadsheet rows aren't kept beyond a render and account data is deleted with the account, and otherwise names no periods (10 of 30). No deprecation policy or notices (0). Hosting is described only as third-party vendors, with no processors or locations named, while the footer says Made in EU (2 of 20). 15 + 10 + 0 + 2 = 27.

Payments & pricing Robolly +10

Contentdrips API and MCP 25

No x402, MPP or L402 (0). No per-call price. The API page shows $0 on paid cards, a $39 starting price and $359 a month for unlimited calls, and the pricing page shows $15 and $26 plans without API, so the public pricing can't be relied on (5 of 20). The API page says 10 API calls to test with and no card for the free plan (20). A person signs up and generates the key in the dashboard (0). 0 + 5 + 20 + 0 = 25.

Robolly 35

No x402, MPP or L402 (0). Plan prices are public and a table gives the credit cost of each format and size (15 of 20). 7-day trial with no card (20). A person signs up, then copies the key or approves OAuth (0). 0 + 15 + 20 + 0 = 35.

Maintenance & community Contentdrips API and MCP +10

Contentdrips API and MCP 15

The newest dated change to the agent surface is the MCP page, published 25 May 2026 and modified 27 May, 163 days before this check (10). No three dated changes since 8 August were found (0). No public changelog. Email support at hello@contentdrips.com, which we didn't test (5 of 15). Not in the official MCP registry and no official SDKs (0). No public package or repository (0). 10 + 0 + 5 + 0 + 0 = 15.

Robolly 5

No changelog, release notes or dated API change was found. The sitemap marks every docs page as modified on 4 November 2026, which reads as a site rebuild rather than a change, so it isn't counted (0). No dated changes since 8 August (0). Support by email, with chat on higher plans; not tested (5 of 15). Not in the official MCP registry and no SDKs (0). No public package or repository (0). 0 + 0 + 5 + 0 + 0 = 5.

Verdicts

Contentdrips API and MCP

Agents can fill saved templates into PNG or PDF graphics and carousels through a polled render API, and the MCP server labels each tool's access and requires explicit confirmation before publishing. There is no status page, OpenAPI file, rate-limit figure or changelog, and the pricing pages contradict each other on what API access costs.

Robolly

Robolly's nine MCP tools, synchronous renders, typed error codes and free cached re-renders keep template rendering cheap and predictable for an agent, and OAuth connections can be revoked per client. There is no OpenAPI file, changelog or dated release, and API access starts at $39 a month after a 7-day trial.

Before you call either

Contentdrips API and MCP

  1. Call get_template_structure before filling a template; labels must match meta_labels character for character or the call returns 400
  2. Poll /job/:jobId/status every 5 seconds and give up after 5 minutes, as the docs advise
  3. Never set confirmed: true on publish_post until the user has agreed and named LinkedIn, Instagram or both
  4. Ask before delete_graphic, delete_post or remove_images_from_post; each deletes permanently
  5. Treat text pulled from blog, YouTube or TikTok links as untrusted input

Robolly

  1. Call get_template_modifications before render to learn the keys a template accepts
  2. Send renders one at a time; the API refuses more than 3 a second with rate-limit
  3. Repeat an identical render freely; it is cached for 45 days and costs nothing
  4. Poll get_render after render_video, since video renders are queued
  5. Stop on render-limit-exhausted and tell the user the monthly credits are spent
