Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security57
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 16 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability75
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 2160 tokens (~135/item across 16 items; 16 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management60
- Stability observed for 18 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Tool Safety75
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- 0 of 2 tool(s) whose name or description implies an irreversible operation declare an MCP destructiveHint annotation; "delete_task" implies "delete" and declares no destructiveHint at all, which the MCP spec reads as destructive by default. See how to fix → Fail
- An AI judge read all 17 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass
How do I install the 402cron MCP server?
402cron is a hosted endpoint at https://402cron.com/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
create_task Create or update a scheduled task ~441
Register a schedule against a destination you have already verified. Idempotent on "name": the same name updates the existing task instead of creating a second one. Creating costs nothing; each delivery ATTEMPT costs one credit.
| Name | Type | Req | Description |
|---|---|---|---|
| body | – | – | The body we send. Stored in the clear, so it must not carry credentials. A non-string is serialized as JSON. |
| cron | string | yes | 5 fields, UTC only, one minute at the finest. Operators: * a-b a,b */n a-b/n. Names: SUN-SAT (day), JAN-DEC (month). Macros: @yearly @annually @monthly @weekly @daily @midnight @hourly. Day-of-week i… |
| headers | object | – | Headers we send with the delivery. Stored ENCRYPTED at rest — put credentials here, never in the body. |
| method | string | – | HTTP method of the delivery. Default POST. GET and HEAD carry no body. |
| name | string | yes | Your name for the task. Unique among your live tasks; creating with an existing name updates it. |
| timeoutMs | integer | – | How long we wait for your server, 250-2000 ms. Answer 202 and do the work behind it. |
| url | string | yes | The https:// destination. It must already be registered and verified — see register_destination. |
No output schema declared.
No examples provided.
delete_destination Delete a destination ~43
Remove a claimed URL. Refused while a task still points at it — delete the task first.
| Name | Type | Req | Description |
|---|---|---|---|
| id | integer | yes | Destination id, as returned by register_destination. |
No output schema declared.
No examples provided.
delete_task Delete a task ~67
Move the task to the recycle bin. It stops firing immediately and can be restored for 30 days with restore_task; after that it is unrecoverable. Credits already spent are not refunded.
| Name | Type | Req | Description |
|---|---|---|---|
| id | string | yes | Task id (UUID), as returned by create_task or list_tasks. |
No output schema declared.
No examples provided.
get_docs Machine documentation ~59
One section of the machine documentation: quickstart, headers, signature, notice, errors, billing or limits. Omit `section` to get the whole document.
| Name | Type | Req | Description |
|---|---|---|---|
| section | string | – | Which section to return. Omit for all of it. |
No output schema declared.
No examples provided.
get_pricing Pricing and payment requirements ~49
What a delivery costs, which packs exist, and the exact x402 payment requirements for each. Balance is counted in DELIVERIES, not money, and packs never expire. Call this before buying.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
get_service_status Is the service selling right now ~44
Whether the service is currently selling, on which network, and if not — why not. This is configuration, not liveness: the full health endpoint is at /health.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
get_task One task with its full state ~51
A single task: schedule, destination, state, next run, and how many failures in a row it carries.
| Name | Type | Req | Description |
|---|---|---|---|
| id | string | yes | Task id (UUID), as returned by create_task or list_tasks. |
No output schema declared.
No examples provided.
list_destinations List your destinations ~28
The URLs you have claimed and whether each is verified. The signing secrets are never shown again.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
list_tasks List your scheduled tasks ~77
Your tasks and their state. Needs your management token as an Authorization header on this connection.
| Name | Type | Req | Description |
|---|---|---|---|
| after | string | – | Cursor from a previous page. |
| limit | integer | – | How many to return. |
| state | string | – | Filter by state: live (default), all, or one exact state such as active or paused_by_client. |
No output schema declared.
No examples provided.
pause_task Pause a task ~43
Stop firing until you resume. Nothing is charged while a task is paused.
| Name | Type | Req | Description |
|---|---|---|---|
| id | string | yes | Task id (UUID), as returned by create_task or list_tasks. |
No output schema declared.
No examples provided.
register_destination Register a destination URL ~275
Claim an https:// URL you control. We answer with a challenge and a SIGNING SECRET that is shown ONCE and never again — store it before you do anything else; it is what lets you verify that a delivery really came from us. The permission covers that path and everything beneath it, nothing above. Verification is one request from us to the exact URL you registered: POST, headers X-402cron-Challenge: <value> and X-402cron-Event: verify, JSON body {"challenge":"<value>"}. Reply within 5 seconds, without a redirect, with a body that is the bare value or {"challenge":"<value>"}; we read the first 512 bytes and do not check the HTTP status (2xx is fine). Then call POST /api/destinations/{id}/verify within 15 minutes of registering. A fixed-response webhook cannot pass: you need an endpoint you can program. Registering a URL that is still pending issues a new challenge and a new signing secret every time — the old secret immediately stops verifying deliveries; a verified URL is left untouched unless you add ?rotate=1. The daily verification allowance (10 per destination, 40 per client, UTC day) does not reset on re-registration.
| Name | Type | Req | Description |
|---|---|---|---|
| url | string | yes | The https:// URL you control. |
No output schema declared.
No examples provided.
restore_task Restore a deleted task ~51
Bring a task back from the recycle bin within 30 days. It comes back PAUSED — resume it explicitly.
| Name | Type | Req | Description |
|---|---|---|---|
| id | string | yes | Task id (UUID), as returned by create_task or list_tasks. |
No output schema declared.
No examples provided.
resume_task Resume a paused task ~47
Start firing again on the schedule. Refused if your balance is empty — buy deliveries first.
| Name | Type | Req | Description |
|---|---|---|---|
| id | string | yes | Task id (UUID), as returned by create_task or list_tasks. |
No output schema declared.
No examples provided.
run_task_now Fire a task once, right now ~81
Deliver immediately, outside the schedule. THIS COSTS ONE CREDIT per attempt, exactly like a scheduled firing, and a timeout or unreachable host is retried up to three times — so one call can cost up to three credits. Use it to test a destination.
| Name | Type | Req | Description |
|---|---|---|---|
| id | string | yes | Task id (UUID), as returned by create_task or list_tasks. |
No output schema declared.
No examples provided.
update_task Edit a task ~477
Change the schedule, destination, method, timeout, headers or body of an existing task. Omit a field to leave it unchanged — sending null is refused, because "unchanged" and "cleared" must not look the same. State is NOT editable here: use pause_task and resume_task.
| Name | Type | Req | Description |
|---|---|---|---|
| body | – | – | The body we send. Stored in the clear, so it must not carry credentials. A non-string is serialized as JSON. |
| cron | string | – | 5 fields, UTC only, one minute at the finest. Operators: * a-b a,b */n a-b/n. Names: SUN-SAT (day), JAN-DEC (month). Macros: @yearly @annually @monthly @weekly @daily @midnight @hourly. Day-of-week i… |

| name | string | – | Your name for the task. Unique among your live tasks; creating with an existing name updates it. |
| timeoutMs | integer | – | How long we wait for your server, 250-2000 ms. Answer 202 and do the work behind it. |
| url | string | – | The https:// destination. It must already be registered and verified — see register_destination. |
No output schema declared.
No examples provided.
verify_destination Verify a registered destination ~227
Verification is one request from us to the exact URL you registered: POST, headers X-402cron-Challenge: <value> and X-402cron-Event: verify, JSON body {"challenge":"<value>"}. Reply within 5 seconds, without a redirect, with a body that is the bare value or {"challenge":"<value>"}; we read the first 512 bytes and do not check the HTTP status (2xx is fine). Then call POST /api/destinations/{id}/verify within 15 minutes of registering. A fixed-response webhook cannot pass: you need an endpoint you can program. Registering a URL that is still pending issues a new challenge and a new signing secret every time — the old secret immediately stops verifying deliveries; a verified URL is left untouched unless you add ?rotate=1. The daily verification allowance (10 per destination, 40 per client, UTC day) does not reset on re-registration. Until this passes, no task may point at the destination.
| Name | Type | Req | Description |
|---|---|---|---|
| id | integer | yes | Destination id, as returned by register_destination. |
No output schema declared.
