Typefully

# Fix list: Typefully

From Anchor Terminal's listing at https://www.anchorterminal.com/tools/typefully, the October 2026 research run, assessed 8 October 2026. Grade D, 49.1 out of 100.

This is everything the published grade says the listing lacks, the biggest possible gain to the total first. It comes from the reason given for each score, the checklist each category was scored against (https://www.anchorterminal.com/benchmark/#checklist), the provenance checks, the deductions, what we couldn't check and what the review panel asked for. A fix counts at the next check, once it's public.

For a coding agent working on Typefully: work through the items below in the product, its docs and its public pages. Each category gives the reason for its score, with the points each checklist item earned, and the checklist itself, so the gap is the items that earned less than their points. Change the product, not the wording, and keep a note of what you changed and where it's published.

## 1. Reliability, 27 out of 100, up to 14.6 more on the total

Why it scored 27: Graded as a hosted service. No status page was found, since status.typefully.com did not connect and the API catalogue's status link is the API root (0). With no page there is no incident history to read (5). Rate limits are documented per user and per social set through response headers, with no figures (5). 429 is documented on every operation with reset timestamps, but no `Retry-After` and no idempotency key for writes (7). No SLA, and the terms supply the service as is (0). API v2 has been live since 17 December 2025 and is not labelled beta (10).

The checklist (https://www.anchorterminal.com/benchmark/#checklist-reliability):

Hosted APIs, MCP servers, models and platforms.

- 20, a public status page with component history (Statuspage, Instatus, BetterStack or the vendor's own).
- 0 to 30, the incident record for the last 90 days on that page. 30 for a clean record or trivial incidents only, 20 for minor incidents only, 10 for one major outage (an hour or more of a core API down, or errors across the board), 0 for several. 5 when there's no history we could read, and the note says so.
- 15, rate limits documented with numbers.
- 15, documented 429 or overload handling (Retry-After, backoff guidance), and idempotency keys or safe-retry guidance where writes are involved.
- 10, an SLA published for any paid tier.
- 10, the surface agents use is generally available, not beta or preview.

Local packages, SDKs, frameworks and stdio MCP servers.

- 20, installs from an official package with supported runtimes stated.
- 25, a public CI and test suite, passing on the default branch.
- 0 to 25, open crash or regression issues relative to activity (25 for few and handled, 0 for many, old and unanswered).
- 15, semver discipline and breaking changes called out in a changelog.
- 15, version 1.0 or later, or declared stable.

Protocols are read from their reference implementations, the public facilitators or servers, spec stability and test vectors.

## 2. Security & auth, 38 out of 100, up to 10.9 more on the total

Why it scored 38: OAuth on the MCP server with PKCE, dynamic client registration and revocation, and revocable API keys, but one scope `full_access` and keys that carry all of the creating user's permissions (20). The MCP article says the old URL form with the key in `?TYPEFULLY_API_KEY=` still works (-10). Read, write and publish access per social set is inherited from the user, and planned drafts need a confirming call, but no read-only key exists (10). Responses hold the workspace's own drafts and teammates' comments, with no injection guidance found (6). Draft Activity records who changed a draft and labels MCP or API as the source (10). No security.txt, bug bounty or certification was found, only a short security section in the privacy policy (2).

The checklist (https://www.anchorterminal.com/benchmark/#checklist-security):

- 0 to 30, the credential model. 30 for OAuth 2.1 with scopes, or scoped and revocable keys with rotation. 20 for plain revocable API keys. 10 for one all-powerful key. 10 off when a secret can travel in a URL query string as a documented option.
- 0 to 20, read-only or least-privilege modes, and confirmation or approval for destructive actions.
- 0 to 15, prompt-injection posture where the tool returns untrusted content (documented mitigations or guidance). A tool that returns no untrusted content gets 10.
- 0 to 15, audit logs or per-call visibility for the operator.
- 0 to 20, a security programme. security.txt or a disclosure policy, a bug bounty, SOC 2 or ISO 27001, advisories handled in public.

Models are read for retention, whether API data trains models (and whether that's off by default), zero-retention options and certifications. Frameworks for telemetry defaults, approval hooks, guardrails and sandboxing.

## 3. Payments & pricing, 30 out of 100, up to 8.8 more on the total

Why it scored 30: No x402, MPP or L402 (0). Plan pricing sits on a public page without a login, but the figures are drawn by script and were not read, so this line rests on the page's plan names and a $12.50 figure in the vendor's blog (10). A free plan exists, the onboarding script skips checkout for it, and the API was announced as available to all users (20). A person signs up in a browser and creates the key in settings (0).

The checklist (https://www.anchorterminal.com/benchmark/#checklist-payments):

The published rubric, also on the [x402 page](https://www.anchorterminal.com/x402/).

- 40, a machine payment protocol (x402, MPP or L402) on the tool's own endpoints. 10 to 30 when it covers only some endpoints or only goes through a third party, and the note says which.
- 20, per-call or per-unit pricing published without a login. 10 for public plan-only pricing, 0 for "contact sales" or prices behind a login.
- 20, a free tier or trial that doesn't need a card.
- 20, autonomous onboarding, meaning an agent can get access without a person signing up in a browser (keyless use, x402, a programmatic key API).

Payment platforms and agent wallets rarely charge for their own API over a machine protocol, so the first line has steps for them, and the highest one that applies counts. 40 when x402, MPP or L402 runs on all their own endpoints, 30 when it runs on part of their own API, 25 when their merchants can accept one, 20 for running a facilitator, 15 for paying as a buyer, and 0 when the only protocol is their own. Merchant acceptance sits above a facilitator because the platform's own customers can charge agents through it, while a facilitator settles for sellers who wire up the protocol themselves. The counter-argument (a facilitator does more for the protocol as a whole) has a point. Each note says which step applied.

Open-source software you run yourself is scored on its hosted or paid option if it has one. A free, self-hosted package with nothing to buy gets 20, 20 and 20 for the last three lines, and 0 to 40 for the first only if it ships a payment protocol.

## 4. Agent ergonomics, 62 out of 100, up to 6.2 more on the total

Why it scored 62: List calls take `limit` up to 50 with a default of 10, and a draft read can drop comment markers, but there is no field selection (15). Limit and offset pagination with status, tag and ordering filters on drafts (20). Errors carry a code, a message and field details with a location path (16). No idempotency key. A planned draft is a write that cannot publish, which makes retries safer for that state only, and MCP tool annotations were not read (4). Creating a draft needs only `platforms`, but there is no official SDK, only the skill's CLI script (7).

The checklist (https://www.anchorterminal.com/benchmark/#checklist-ergonomics):

- 0 to 25, context cost. For MCP, the number and size of the tool definitions (25 for ten or fewer compact tools, 15 for 11 to 30, 5 for more than 30, plus up to 10 back for toolsets, dynamic loading or read-only subsets). For APIs, whether responses can be sized (field selection, limits, summaries).
- 20, pagination, filtering and output-size controls.
- 20, actionable, documented error responses, codes and messages an agent can recover from.
- 20, idempotency or safe retries, and for MCP the `readOnlyHint` and `destructiveHint` annotations.
- 15, sensible defaults, few required parameters, and official SDKs in at least two languages.

Models are read for tool use, structured output, prompt caching, context length, batch and SDKs. Frameworks for how much code and how many defaults a tool-calling agent with MCP needs.

## 5. Transparency & trust, 64 out of 100, up to 3.2 more on the total

Made of editorial 55, provenance 72.

Why it scored 64: Closed service under published terms, with the Agent Skill under MIT (15). The privacy policy says deleted data is purged within 30 days, that AI providers may not train on customer data and that data is processed in the United States, and it links a sub-processor list. No DPA was found, and the terms say only that data may be kept for a limited period (20). No deprecation policy. The v1 to v2 migration guide gives no end date for v1, `draft_id` is marked deprecated with no date, and the terms may change without notice (4). About 30 sub-processors listed by purpose on a page dated 3 March 2026, without locations for each (16).

The checklist (https://www.anchorterminal.com/benchmark/#checklist-transparency):

- 0 to 30, source availability and licence clarity. 30 for open source under an OSI licence, 15 for closed with clear terms, 0 for unclear terms.
- 0 to 30, data handling and retention statements that agree with each other (privacy policy, DPA, retention periods, subprocessors).
- 0 to 20, a deprecation policy or notices with dates.
- 0 to 20, telemetry disclosed with an opt-out (local software), or subprocessors and data locations disclosed (hosted).

The other half of Transparency and trust is the provenance score, computed from checked facts (below). The category score is the mean of the two.

Provenance checks not met in full (half of this category, computed from checked facts):

- Terms of service: read, states 4 of the 7 things a reader expects, and has 2 clauses that cost points (3.4 of 10)
- Privacy policy: read, states 6 of the 8 things a reader expects (8.5 of 10)
- Status page: not found (0 of 10)
- security.txt: not found (0 of 10)

## 6. Schema & documentation, 83 out of 100, up to 2.8 more on the total

Why it scored 83: Public OpenAPI 3.1.0 document for 24 operations and seven webhook events (25). `llms.txt`, the full reference as Markdown and an RFC 9727 API catalogue (10). Descriptions state purpose, the permission each call needs and how drafts move between states, with less on when not to use a call (15). Inputs are typed per platform with 18 enums, length limits and required fields, though `publish_at` mixes keywords and datetimes in one string (12). 239 examples and error responses on every operation, with no list of error codes (11). The version is in the path and API changes are dated in the product changelog, with no API changelog of its own (10).

The checklist (https://www.anchorterminal.com/benchmark/#checklist-schema):

APIs and MCP servers.

- 25, a machine-readable contract (a public OpenAPI file or similar; for MCP, typed JSON Schema inputs on every tool).
- 10, llms.txt or Markdown docs served for agents.
- 0 to 20, descriptions that say what a tool is for, when to use it and when not to, read from the tool definitions in the source or the API reference.
- 0 to 15, typed inputs with enums, constraints and required fields, and no free-form JSON blobs.
- 0 to 15, examples and documented error responses.
- 15, versioning and a public changelog.

Models are read from the API reference, the OpenAPI file, llms.txt, the structured-output and tool-use docs and the model cards. Frameworks from docs a model can follow, typed interfaces, examples and the API reference.

## 7. Maintenance & community, 82 out of 100, up to 1.6 more on the total

Why it scored 82: Product changelog entry on 20 September 2026 and an agent-skills commit on 1 October 2026 (30). Five dated changelog entries between 8 July and 20 September 2026 (20). Public changelog, a Discord community, email and in-app chat, with no public issue tracker for the API (10). Listed in the official MCP registry as `com.typefully/mcp`, active since 1 September 2026 (15). The skill repository runs a test workflow, and there is no SDK to judge (7).

The checklist (https://www.anchorterminal.com/benchmark/#checklist-maintenance):

- 0 to 30, time since the last release, or the last published model or API change for a closed service. 30 within 30 days, 20 within 90, 10 within 180, 0 older.
- 20, at least three releases or dated changelog entries in the last 90 days.
- 0 to 25, responsiveness. Issues and pull requests answered on GitHub (the open issues and how recent the replies are). For closed services, a public changelog and a support or community channel that answers, 0 to 15.
- 15, presence in the official MCP registry under a verified namespace (MCP servers), or current official SDKs (APIs and models).
- 10, package health, current dependencies and CI.

Models are read for deprecation notice periods and model churn rather than release counts.

## Deductions

Each comes off the total. A fixed and documented problem counts for less at the next check.

- 2026-07-09. The vendor's own agent-skills changelog records that the API's tightened request schemas began rejecting platform-specific fields on the wrong platform with HTTP 422, which broke `drafts:update` in the vendor's CLI until it was patched the same day. No notice was found in the product changelog. Fixed on the client side and documented there, so -3 (https://github.com/typefully/agent-skills/blob/main/skills/typefully/CHANGELOG.md)

## What we couldn't check

What we couldn't read counted as absent. Publishing it on a page a plain HTTP fetch can read (not only in a browser) lets the next check count it.

- unchecked: the plan prices and limits on https://typefully.com/pricing, which the page draws by script. Payments is scored from the plan names in the page's scripts and one figure in the vendor's blog
- unchecked: the MCP server's tool list, descriptions and annotations, which need a signed-in session
- Whether the free plan can publish through the API or only save drafts. The reference documents a `publishing_quota` and a 402 response without figures
- Whether API v1 is still served and when it ends. The migration guide gives no date
- Whether customers were told before the 9 July 2026 schema tightening. No notice was found in the product changelog
- The numeric rate limits. Only the header names are published
- No status page was found by looking at the site footer, the docs and status.typefully.com, which did not connect. One may exist at an address we did not find
- The lead was right on the interface. llms.txt names Instagram as a platform, and the API schema has none

## Weaknesses

- Rate limits are described by response headers only. No request numbers are published, and no `Retry-After` header is documented
- No status page, incident history or SLA was found. The terms supply the service as is
- No idempotency key on draft creation, so a retried `publish_at: "now"` call can post twice
- OAuth has one scope, `full_access`, and an API key carries every permission of the user who created it
- The terms say accounts must be registered by a human and forbid processes that run while the user is not logged in

## What costs an agent a turn today

The notes we give agents before they call it. Each one is a workaround an agent shouldn't need.

- Call `GET /v2/social-sets` first. Every draft, media, tag and queue path needs a `social_set_id`
- Use `plan_at` or omit both dates to leave a draft unpublished. `publish_at: "now"` posts at once and is asynchronous
- Do not retry a failed publish blindly. Read the draft's `status` and `publish_state` first, because no idempotency key exists
- Read `X-RateLimit-User-Remaining` and `X-RateLimit-SocialSet-Remaining` on each response, and wait until the `Reset` timestamp after a 429
- Send the key only as `Authorization: Bearer`. The legacy MCP URL with `?TYPEFULLY_API_KEY=` still works and puts the key in logs

## When it's done

Send what changed and where it's published as a dispute (https://www.anchorterminal.com/builders/#disputes, or `POST https://www.anchorterminal.com/api/v1/contact` with `"kind": "dispute"`). Disputes are answered in public, and the listing is checked again by the same checklist. Paying for an audit or a listing claim changes nothing here.
