Server Configuration

Describes the environment variables required to run the server.

NameRequiredDescriptionDefault
ADDY_API_KEYNoYour addy.io API key.
ADDY_BASE_URLNoFor self-hosted addy.io instances, e.g. `https://addy.example.com`. Defaults to `https://app.addy.io`.
ADDY_READ_ONLYNoSet to `true` to hide every tool that can change your account. Claude can then only look things up.
ADDY_API_KEY_FILENoPath to a file containing the key, instead of ADDY_API_KEY. Takes precedence if both are set. One of the two is required.

Instructions

Guidance the server publishes about itself, which clients place ahead of the tool catalog so the model reads it before choosing anything.

Tools for managing an addy.io (formerly AnonAddy) email-forwarding account.

Concepts:

  • Alias: a forwarding address (e.g. shop123@anonaddy.me). Mail sent to it is forwarded to one or more recipients.

  • Recipient: a real mailbox that aliases forward to. New recipients must be verified by email.

  • Username: an extra username giving its own subdomain (e.g. anything@myname.anonaddy.com).

  • Domain: a custom domain the user owns and has connected to addy.io.

  • Rule: conditions + actions applied to forwarded/replied/sent mail.

  • Blocklist: senders/domains whose mail is rejected.

Most tools take ids (UUIDs). Look them up with the list_* tools first. Deleting an alias is reversible (restore_alias); forgetting an alias is permanent. Confirm with the user before deleting or forgetting anything.

Tools

Functions exposed to the LLM to take actions

NameDescription
get_account_detailsA

Get account details: username, plan/subscription, bandwidth used, default alias domain/format, limits, etc.

get_api_token_detailsA

Get the name, creation date and expiry of the API token this server is using.

get_account_notificationsB

Get account notifications/announcements from addy.io.

get_domain_optionsA

Get the domains available for creating aliases, plus the account's default alias domain and format.

get_app_versionA

Get the addy.io app version (only available on self-hosted instances).

list_aliasesB

List or search aliases. Results are paginated; the response includes meta with totals and page counts.

get_aliasA

Get a single alias, including its recipients, labels and statistics.

create_aliasB

Create a new alias. Use get_domain_options to see which domains are available.

update_aliasB

Update an alias's description, from name, or labels. Only the fields you pass are changed.

delete_aliasA

Delete an alias. It stops receiving mail but can be brought back with restore_alias.

restore_aliasC

Restore a deleted alias.

forget_aliasA

PERMANENTLY forget an alias: it is disassociated from the account and cannot be restored.

set_alias_optionB

Turn an alias option on or off (activate/deactivate, pin/unpin, limit reply/send to attached recipients).

set_alias_recipientsB

Replace the set of recipients an alias forwards to.

set_alias_labelsB

Replace the labels attached to an alias.

bulk_alias_actionA

Apply one action to up to 25 aliases at once (or fetch them with action='get').

bulk_set_alias_recipientsB

Replace the recipients of up to 25 aliases at once.

bulk_set_alias_labelsB

Replace the labels of up to 25 aliases at once.

list_recipientsA

List the account's recipients (the real mailboxes aliases forward to).

get_recipientB

Get a single recipient and its settings.

create_recipientA

Add a new recipient. addy.io emails it a verification link; it can't be used until verified.

update_recipientB

Set a recipient's description.

delete_recipientA

Delete a recipient. Aliases that used it fall back to the default recipient.

resend_recipient_verificationA

Resend the verification email for an unverified recipient.

add_recipient_public_keyA

Add a public GPG key to a recipient so forwarded mail can be encrypted.

remove_recipient_public_keyB

Remove a recipient's public GPG key (this also turns off encryption for it).

set_recipient_optionC

Turn a recipient option on or off.

list_usernamesA

List the account's usernames (each gives a subdomain like name.anonaddy.com for on-the-fly aliases).

get_usernameC

Get a single username and its settings.

create_usernameA

Create an additional username (counts against the plan's username limit).

update_usernameC

Update a username's description, from name, or auto-create regex.

delete_usernameB

Delete a username. Its aliases stop working.

set_username_default_recipientA

Set (or clear) the default recipient for aliases on a username.

set_username_optionC

Turn a username option on or off.

list_domainsA

List the custom domains connected to the account.

get_domainA

Get a single custom domain and its settings/verification status.

create_domainA

Add a custom domain. Its DNS must already have the TXT verification record addy.io shows in its dashboard.

update_domainC

Update a custom domain's description, from name, or auto-create regex.

delete_domainA

Delete a custom domain. Its aliases stop working.

set_domain_default_recipientB

Set (or clear) the default recipient for aliases on a custom domain.

check_domain_sending_recordsB

Check a custom domain's DNS records (SPF, DKIM, DMARC, ...) for sending/replying from aliases.

set_domain_optionC

Turn a custom domain option on or off.

list_labelsC

List the labels used to organise aliases.

get_labelC

Get a single label.

create_labelC

Create a label for organising aliases.

update_labelB

Rename a label or change its colour.

delete_labelB

Delete a label (aliases are kept, just unlabelled).

list_rulesA

List all rules, in the order they are applied.

get_ruleA

Get a single rule with its conditions and actions.

create_ruleA

Create a rule that runs actions on emails matching conditions.

Example: block newsletters to a specific alias -> conditions=[{type:'alias', match:'is exactly', values:['shop@anonaddy.me']}, {type:'header', match:'exists', values:['List-Unsubscribe']}], actions=[{type:'block'}].

update_ruleA

Update a rule. Only the fields you pass change; the rest are kept from the current rule.

delete_ruleC

Delete a rule.

reorder_rulesB

Set the order rules are applied in.

set_rule_activeC

Activate or deactivate a rule.

list_blocklistB

List blocked senders/domains, with how many emails each has blocked.

add_to_blocklistA

Block mail from sender email addresses or whole domains, across all aliases.

remove_from_blocklistA

Unblock blocklist entries by id (see list_blocklist).

list_failed_deliveriesA

List emails that addy.io failed to deliver (or quarantined).

get_failed_deliveryB

Get details of a failed delivery (sender, alias, bounce reason, ...).

download_failed_deliveryA

Download the raw email (.eml source) of a failed delivery, if addy.io stored it.

B3.1/5.0

Scored across 62 tools

Disambiguation4/5

Each tool targets a distinct resource+action, and the descriptions carefully separate delete_alias / restore_alias / forget_alias and the three bulk tools. Some overlap remains: update_alias can change labels while set_alias_labels exists, and bulk_alias_action acts as a catch-all that shadows the per-alias update/delete/option tools. The generic set_*_option tools also require guessing valid option names.

Naming Consistency4/5

The set is dominated by a clean verb_noun snake_case pattern (get_alias, create_recipient, set_domain_option, resend_failed_delivery). A few deviations break the pattern: bulk_alias_action is vague where its siblings are bulk_set_alias_* , forget_alias uses a non-standard verb, and blocklist tools mix list_blocklist with add_to_blocklist / remove_from_blocklist.

Tool Count2/5

62 tools is heavy for an alias-management API; four near-identical set_*_option tools (alias, domain, username, recipient) plus four bulk variants could be consolidated. Several resources get full CRUD plus option/default-recipient/DNS sub-tools, inflating the surface well past the comfortable 3-15 range.

Completeness4/5

Coverage is broad and lifecycle-complete for aliases, recipients, domains, usernames, rules, labels, blocklist and failed deliveries, including soft-delete/restore and bulk paths. Minor gaps: API tokens are read-only (no create/revoke), and there is no standalone alias statistics or DNS-record-set operation beyond checking/setting options.
