Tools & capabilities
Discourse MCP tools 16
discourse_select_siteValidate and select a Discourse site. Returns JSON with site URL and title.discourse_searchSearch site content. Returns JSON object with results array of matching topics (id, slug, title) and meta (total, has_more).discourse_filter_topicsDiscover topics through a filtered, top, or hot view. Filtered uses Discourse TopicsFilter syntax; top uses Discourse's authoritative top score and defaults to weekly; hot is defined exactly as daily top (not sentiment, controversy, or real-time velocity). Returns a uniform rich topic projection and truthful pagination metadata.discourse_read_topicRead topic metadata and posts. Large post limits can require multiple upstream requests. For moderation queues, prefer reviewable list/detail evidence instead of fanning this tool out across flagged topics.discourse_read_postRead a specific post. Returns JSON with id, topic_id, post_number, username, created_at, and raw content.discourse_read_topic_postsRead exact, earliest, latest, around-post, or username-filtered topic evidence. Selection is bounded to 50 posts and reports the visible stream size without claiming the entire topic was loaded.discourse_search_postsSearch post-level evidence with Discourse query syntax. Unlike discourse_search, this preserves matched posts, highlighted blurbs, authors, topics, categories, and truthful bounded continuation. This is keyword search, not Discourse AI semantic search.discourse_get_userGet user info. Returns JSON with id, username, name, trust_level, created_at, bio, admin, and moderator.discourse_list_user_postsGet paginated list of user posts/replies. Returns JSON object with posts array (id, topic_id, post_number, slug, title, created_at, excerpt, category_id) and meta (page, limit, has_more).discourse_list_usersList users via admin API. Requires admin API key. Returns ~100 users per page (Discourse's fixed page size). Returns JSON with users array and pagination meta.discourse_get_chat_messagesGet messages from a chat channel. Returns JSON object with channel_id, messages array (id, username, created_at, message, edited, thread_id, in_reply_to_id), and meta.discourse_get_draftRetrieve a specific draft by key. Returns JSON with draft_key, sequence, and parsed data (title, reply, categoryId, tags, action).- +4 more on the listing page

proxyllm_savings_calculatorGiven a monthly OpenAI API bill in USD, returns the ChatGPT/Codex subscription tier that absorbs that workload through ProxyLLM Codex Hosted, the flat total (subscription + $129 fee), and the monthly savings. Free, no auth.proxyllm_list_modelsOpenAI-shaped model list from the gateway. No auth required; with a routing key it reflects that key's lanes, including the live Codex catalog.proxyllm_introspect_keyGET /v1/key: the key's provider lanes, reachable models, whether a Codex subscription backs it, and monthly budget state. Authed by the routing key itself.proxyllm_signupStarts autonomous account creation: a 6-digit code is emailed to the operator's inbox (no captcha, no browser). New accounts are unpaid and are removed after 48 hours unless a human activates the membership. Follow with proxyllm_verify_signup.proxyllm_verify_signupExchanges the 6-digit code for an sk_ account token. The token is returned exactly once: store it (PROXYLLM_ACCOUNT_TOKEN). While the account is unpaid the response carries a checkout link to relay to the operator.proxyllm_accountGET /v1/organizations/me. Works while unpaid: plan is "free" plus a payment block until the operator activates the membership, then "pro". Poll this after handing over the checkout link.proxyllm_create_routing_keyMints a pllm_ routing key (returned once) for OPENAI_API_KEY-style use against the gateway. Optionally wires the provider chain in the same call; discover wireable lane ids with proxyllm_list_routing_keys include_lanes.proxyllm_list_routing_keysLists the account's routing keys. include_lanes adds the wireable lanes (connected Codex sessions, bridges, saved provider keys) with the ids provider chains reference.proxyllm_usageGET /v1/organizations/usage for the account.
