# Consul Intention Check
Command: `consul intention check`
The `intention check` command checks whether a connection attempt between
two services would be authorized given the current set of intentions and
Consul configuration.
This command requires less ACL permissions than other intention-related
tasks because no information about the intention is revealed. Therefore,
callers only need to have `service:read` access for the destination. Richer
commands like [match](/commands/intention/match) require full
intention read permissions and don't evaluate the result.
-> **Note:** This command will always treat intentions with `Permissions`
defined as _deny_ intentions during evaluation, as this endpoint is only suited
for networking layer 4 (e.g. TCP) integration.
## Usage
Usage: `consul intention check [options] SRC DST`
`SRC` and `DST` can both take [several forms](/commands/intention#source-and-destination-naming).
