# DESCRIPTION A [MCP::Server::KnowledgeStore::Tools](https://metacpan.org/pod/MCP%3A%3AServer%3A%3AKnowledgeStore%3A%3ATools) plugin registering `list_specs`, `search_specs`, `get_spec`, `save_spec`, `list_spec_revisions`, `mark_spec_useful`, and the archive, restore, purge, and archived-list tools against a [MCP::Server::KnowledgeStore::Store](https://metacpan.org/pod/MCP%3A%3AServer%3A%3AKnowledgeStore%3A%3AStore). Unlike memory and skill, a spec's `project` is required and single. A spec document belongs to exactly one project, so there is no tag/untag pair. # SYNOPSIS use MCP::Server::KnowledgeStore::Tools::Spec; MCP::Server::KnowledgeStore::Tools::Spec->register($mcp_server, $store); # METHODS ## register MCP::Server::KnowledgeStore::Tools::Spec->register($server, $store); Adds this plugin's tools to `$server` (an [MCP::Server](https://metacpan.org/pod/MCP%3A%3AServer)), backed by `$store`. Called by ["build" in MCP::Server::KnowledgeStore::Tools](https://metacpan.org/pod/MCP%3A%3AServer%3A%3AKnowledgeStore%3A%3ATools#build) for every installed plugin - not normally called directly.
