Cenno helps event professionals and students develop creative pre-designs for exhibition stands, indoor corporate events, outdoor events and seasonal Christmas installations, plus photo opportunities, event renders and animation planning. Eleven focused skills include a neutral workflow selector and ten specialties. Stand, indoor and Christmas design provide text-based concepts, spatial planning, English prompts, a modeling handoff guide and descriptive inventories; they do not create 3D models or generate media. Christmas design considers theme, tree, activities and existing inventory supplied through photos and dimensions, including seasonal decoration for malls, outdoor spaces, homes and offices. Other skills cover drone shots, virtual tours, construction timelapses and plenary-to-dinner transformations. Starts immediately without a conversational password or language-selection step. Conversation automatically follows the user's language; visual prompts remain in English. Media generation depends on tools and limits in each user account. The remote MCP calculator estimates photo opportunity composition for 1 to 12 people; it does not generate media, persist briefings, call an AI API, purchase services or perform structural calculations. Outputs are creative pre-designs, not construction documents or safety certifications. Dedicated light-show animation is not included.
Hanna Group LLC
A managed, read-only email connector that lists accounts and folders, searches messages, reads selected message text, analyzes bounded email activity, and reconstructs conversations. It cannot send, draft, reply, forward, move, delete, flag, mark mail read, or download attachments.
Centiment LLC
Browse and analyze your Centiment organizations, workspaces, surveys, and survey responses directly from ChatGPT. The Centiment MCP Server provides secure, read-only access to survey data you already have permission to view, making it easy to discover surveys, inspect responses, and summarize findings without leaving ChatGPT.
Cerber
Cerber for Business protects the Telegram accounts a company's employees use for work, and keeps an encrypted archive of their work conversations that the company controls. This plugin lets ChatGPT work with that archive and with the protection itself, inside one organization and only within what an administrator approves.
When you connect, you sign in to Cerber, choose which accounts ChatGPT may read, and choose what it may do. Reading is the default. Acting on accounts, changing security settings, managing administrators and deleting archived data are separate permissions that are off unless you tick them, and ticking them asks for your console password. ChatGPT acts as you and can never do more than your role allows; every request is recorded in your organization's journal.
With the archive permission ChatGPT can list chats and folders, read conversations page by page, search across accounts (including document text and voice transcripts), see who was in a group, see every earlier version of an edited message and messages that were deleted in Telegram, and open photos, voice notes and documents.
With the organization permissions ChatGPT can report on accounts, Telegram sessions and their review deadlines, departments, administrators, the security journal and system status, and, if you allow it, approve or end sessions, pause protection, move accounts between departments, or start a backup.
To read the archive, Cerber's server keeps your archive password with this connection and decrypts on ChatGPT's behalf; disconnecting deletes it. Organizations that need the password never to leave their computers can use the local mode described in the documentation.

Keep your place memory with you when you plan a trip or decide where to go. Connect your Cerca account to use your want-to-go places, loved and liked places, taste profile, and recommendations from people whose places you are allowed to see. Compare your places with a friend, recall past favorites, and find details for places already known to Cerca. When you ask, save a place for later, rate somewhere you visited, update notes, remove your own places, import up to 25 places at once, or start an import from a shared Google Maps list and check its progress. Cerca distinguishes friends' recommendations from its own editorial picks. Want-to-go notes are private; rating notes are public on your profile. Rating a saved place moves it out of want-to-go. Search covers Cerca's catalogue; Google place lookups help resolve saves and ratings and may enrich details, subject to daily limits. Your assistant creates recommendations from returned data. A Cerca account and OAuth authorization are required; write actions require write access. You can revoke connections in Settings → AI assistants. Reservations, bookings, payments, private Google account access, and continuous Google Maps synchronization are unsupported.
Cerebrium
Cerebrium runs Python workloads on serverless GPU and CPU with scale to zero and per second billing: REST endpoints, SSE streaming, WebSockets and async jobs, all described by one cerebrium.toml and driven by one CLI.
This plugin helps you go from a Python function to a deployed endpoint, and then keep it healthy. It covers choosing hardware, regions and the right runtime, writing and fixing cerebrium.toml, picking a scaling metric that matches the workload, calling the endpoint over REST, streaming, WebSocket or async, handling secrets and environment variables, wiring CI/CD with a service account, and debugging a failed build or an app that is queueing or returning 5xx.
It is built for inference APIs for language, embedding and vision models, real time voice and video apps, bursty traffic that should not hold idle GPUs, multi region deployments, and migrations from Replicate, Hugging Face or Mystic.
CertArc
CertArc helps you prepare for the CISSP, CISM, CISA, AAISM and AAIA exams with realistic scenario practice and a clear read of where you stand, in ChatGPT.
Practise without an account:
Connect your CertArc account to ask about your own study, across every certification you take with CertArc:
Open the full-screen view to see Readiness, Patterns and Results, and switch between your certifications.
Read-only and private: the assistant never sees the text or answers of your CertArc questions, never answers for you, finishes sessions or changes your plan, and you can disconnect at any time. Readiness is a study measure, not a pass prediction.
Certifier sp. z o.o..
Certifier is a digital credentials platform that enables you to create, manage, and verify digital certificates and badges at scale.
CertScore.ai, LLC
Scan public websites for fast preliminary cookie/tracker evidence, then continue to persisted privacy findings, typed GPC response comparisons, bounded Accept and Reject observations, policy signals, and HTTPS/TLS. Results preserve provenance and explicit coverage limitations for human review; they are not legal advice, certification, or a compliance determination.

CFDAgent helps researchers and engineers work through computational fluid dynamics and fluid-mechanics problems in conversation. Discuss the physics, compare suitable solvers and their preparation and compute costs, set up cases, review mesh quality, plan runs, examine results, and prepare reproducible postprocessing and reports.
The plugin provides concise guidance and references that the host loads as needed. It follows the current task and evidence rather than a fixed sequence. Working notes help continue an existing project, and exported figures are inspected for readability.
References cover OpenFOAM, SU2, FDS, MFiX, DualSPHysics, code_saturne, Basilisk, Nek5000/nekRS, Palabos, OpenLB, Nektar++, PyFR, and PyIB. Solver choice depends on the problem and available evidence.
Actual simulations require host tools that can access the project and execute commands, a suitable solver, and the necessary compute environment. The plugin does not bundle solvers, provide a hosted computation service, or require an MCP server. Available execution features depend on the host and the user's environment.
Developed by Zhaoyue Xu, Experimental Zoology Group, Wageningen University & Research (WUR), Netherlands.

Read public Chapa developer evidence profiles, explain their scores, compare compatible profiles, and generate live badge embeds. Chapa records authorized development activity in policy-labelled receipts. Its core score combines up to 60 activity points with up to 40 points from optional adoption evidence for one product. Delivery, Quality, Consistency and Breadth are activity diagnostics. Optional report-derived Craft is separate and does not change the core score.
Nine public, read-only tools resolve profile links, read the selected receipt and history, compare profiles, explain dimensions and verification, check a supplied badge token, and return Markdown or HTML embeds. The assistant must preserve the returned policy, observation period, freshness and coverage. Profiles require owner sign-up; collection or unavailable states are reported without an invented score. Comparisons can be unavailable when policies or periods differ.
For v7.5 receipts, Craft estimates outcomes among classified sessions and discloses classified coverage; unknown and unclassified sessions are excluded from that estimate. Earlier receipts keep their original rules. Evidence bands are not worldwide rankings or judgments of ability. Adoption counts are analytics identifiers, not verified people, revenue or proof of causal impact. Verification distinguishes recorded issuance, signature authentication and arithmetic replay; it does not independently verify source truth.
No Chapa sign-in is required to use this plugin. It exposes public aggregates, not credentials, private repository identities, raw reports or provider records. Account connections, report uploads and badge configuration changes take place on the Chapa website.
Chaptershift
Chaptershift is where writers plan and write their novel: the premise, the characters and places of the story, the timeline, the scenes, and the prose of every chapter. This plugin connects ChatGPT to your Chaptershift book projects. You can ask it to read what your story already holds and build on it, create and update characters, locations and scenes, save the prose you write together into a scene, generate a character portrait, a location picture or a cover, and download your manuscript. Everything you change here appears in Chaptershift, and everything you write in Chaptershift is available here. You sign in with your Chaptershift account.
