Tool behavior grows additively — new include sections and modes never break an existing call. Renames and changes that could affect your integration are called out explicitly.

Skill bundles and exact-tool selection

  • Skill bundles — three ready-made skills (Podcast Intelligence, Company Deep Dive, Guest & People Research): a connection URL scoped to just the tools each workflow needs, plus a copy-paste SKILL.md that teaches your agent the workflow.
  • ?tools= selector — pin a connection to exactly the tools you want advertised: ?tools=particle_podcast_resolve,particle_podcast_search_transcripts. See Tool sets & discovery.
  • More clients in the quickstart — Windsurf, Zed, ChatGPT developer mode, and server-side wiring examples for the Anthropic Messages API and OpenAI Responses API. Quickstart.

​
Connect without a browser

  • API keys as MCP credentials — the server now accepts the same pp_* project API keys as the REST API (Authorization: Bearer or X-API-Key), so headless agents — cron jobs, the OpenAI Responses API, server-side harnesses — no longer need an interactive OAuth consent. OAuth remains the recommended path when a human is present. Authentication.
  • One-click installs — Cursor and VS Code install buttons in the Quickstart.
  • llms.txt — now opens with instructions for LLM agents: which surface to pick, how the tools compose, and the conventions that save wasted round-trips.

​
Smarter discovery on connect

  • Conventions taught up front — connecting clients now receive server instructions covering the two things a bare tool list doesn’t show: tools are lean by default and expand via include/mode/format parameters, and every slug a tool returns is a valid input to the other tools (resolve a name once, then traverse).
  • particle_catalog shows each tool’s depth — the catalog menu lists every tool’s expand options (↳ include: … · mode: …), so an agent can see what a tool can really do before fetching its full schema.

​
25 tools, flat names, opt-in categories

  • Renames (action needed if you call tools by name) — every tool moved to a flat particle_* identifier, e.g. entities/resolve_entity → particle_entity_resolve. The tool reference lists all current names.
  • Consolidations — search_dialogue and list_clips merged into particle_podcast_search_transcripts: relevant clips now arrive inline on search matches, and a known episode’s full clip list comes from particle_podcast_get_episode with include: ["clips"]. get_entity_mentions became particle_podcast_find_mentions. Boolean flags on get-tools became include arrays.
  • 12 new tools — people profiles and resolution, podcast guests, chart rankings, publishers, listener ratings, and political-bias and brand-suitability analytics. Browse them in the tool reference.
  • Default vs opt-in advertisement — six tool categories advertise on a bare connection; five more (advertising, publishers, ratings, bias, suitability) advertise when you opt in with ?include=. Every public tool stays callable by name either way, and the always-on particle_catalog / particle_call meta-tools let any connection discover and reach the full surface. Tool sets & discovery.

Launch

  • The Particle Pro MCP server ships at https://mcp.particle.pro: read-only tools over podcasts, companies, and the knowledge graph, with OAuth 2.1 and markdown outputs designed for agent loops.
  • MCP requests and per-tool usage appear in your organization’s request logs alongside REST traffic.
