Cerebrium
By 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.

Cerrax Removals Estimator
By Cerrax Ltd
aMoving house and wondering what it will cost? Ask Claude, and it can use Cerrax to give you an indicative price range for a home removal. Cerrax is pricing and job-management software for removals firms. Its pricing engine is deterministic: the same job always gives the same answer. This connector runs a move through that engine at reference rates and returns: - a price range in the local currency - what the estimate assumes (home size, distance, access) - a link to Cerrax's price check, where you can compare and find firms Just give the two postcodes (or ZIP codes) and the number of bedrooms. It works in every region where Cerrax pricing is live; ask it to list them. It is an estimate, not a quote: a removals firm surveys the job and sets the real price. The connector needs no account and stores nothing personal. Please don't share names, emails, phone numbers or street addresses; postcodes are enough.

CertArc
By CertArc
CertArc helps you prepare for the CISSP, CISM and CISA exams with realistic scenario practice and a clear read of where you stand, in ChatGPT. Practise without an account: - Scenario questions for CISSP, CISM and CISA, one at a time - Choose an answer and how sure you are: Confident, Unsure or Guess - See the correct option and why each option is right or wrong - Exam outlines: every domain and its weight Connect your CertArc account to ask about your own study, across every certification you take with CertArc: - Readiness Score: how it is built and which retakes raise it most - Blind spots: answers you were Confident about but got wrong - Weakest domains and knowledge areas, and why you miss: what you know, how you decide or how you read - Pace: your time per question against the exam pace - Sprint and practice exam results, take by take, with each answer's result, confidence, time and miss reason - Your study calendar: what is next, what is due this week and anything overdue 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.

CertPie
By CertPie
CertPie is a certificate management platform for issuing QR-verified certificates at scale - course completions, workshops, internships, and events. Institutions design a template once, then generate hundreds of personalized certificates from a spreadsheet, each with a QR code that lets anyone verify its authenticity against the issuer's own record. This connector lets Claude: - List your workspace's templates and the exact field names each one needs - Queue one or many certificates for background generation from a template - Check a batch's progress, or look up a single certificate's status and public verification link - List recent certificate batches - Subscribe or unsubscribe a webhook so you're notified the moment a batch finishes, instead of polling Requires a CertPie Business-plan workspace. Sign in with your existing CertPie account to connect - no setup needed beyond that.

CertScore.ai
By CertScore.ai
Use CertScore when you want Claude to scan or audit a website for cookies, trackers, consent behavior, GDPR/ePrivacy risk signals, privacy-policy gaps, TLS, CMP or related CCPA/CPRA signals. Claude can start a scan, retrieve the result, inspect pre-consent cookies and trackers, and explain findings in plain language. Results are automated public-web observations for review, not legal conclusions or compliance determinations. Ask Claude to: scan a domain for GDPR/CCPA compliance signals, pull the latest completed scan for a site, explain a specific finding in plain language, or export findings into a report for legal or a client. The compact scan bundle returns status, findings, supporting evidence, and the exact pre-consent cookies/trackers detected in one retrieval step.

CertifiKit COI Tools
By CertifiKit
Free certificate of insurance (COI) tools for general contractors, property managers and HOA boards. Four read-only tools: - build_insurance_requirements: the general liability, auto, umbrella and workers' comp limits and the additional insured, waiver of subrogation and primary/non-contributory wording to require of a subcontractor or vendor, scaled to the trade's risk and contract size, with the reasoning for each limit and contract-ready exhibit text. - check_certificate: checks an ACORD 25 against a preset or those requirements.

Cetient Case Law
By Cetient, Inc.
Cetient Case Law is a legal-research plugin for finding US court opinions relevant to a legal question. It uses semantic search of Cetient's case-law database. Results are limited to the citation metadata needed to identify and verify a public opinion: case name, citations, court, filing date, precedential status, and source link. The plugin does not return internal record identifiers, opinion text, or summaries. No Cetient account is required. The search excludes opinions marked Unpublished. Jurisdiction and date mentions are semantic hints, not strict filters. Results are not exhaustive and do not establish that a case remains good law. Verify the linked full opinion and consult a qualified lawyer before relying on results; this tool provides legal information, not legal advice. Submit legal issues rather than confidential client facts or personal identifiers. Queries are processed by Cetient and its embedding provider. Cetient logs service usage, including pseudonymous network fingerprints, for operations and usage analytics; see the privacy policy for data practices.

Chain of Title
By Chain Of Title LLC
Chain of Title records every Solana token launch at its creation transaction and keeps what the launch published about itself: its name, ticker, description, links and image, fetched and hashed at the moment of capture. Over 1.8 million launches are on record, more than 1.7 million of them observed at the creation transaction, with continuous coverage since 2 September 2026. Those documents are served from addresses their publishers control, and they stop answering without notice. Of 5,522 re-requested between one and 45 days after launch, 1,004 were no longer served. Where the original address has gone quiet, the copy in this register is often the only one that remains. Three tools return observations from the record, each with the transaction or hash it rests on and a citation URL so any figure can be checked at the source. There are no scores, no grades and no advice. A launch the register did not observe returns a not-observed result, which records the absence of an observation and is not a statement about the launch.

Chaiz
By Chaiz, Inc.
Chaiz is the first online marketplace for vehicle service contracts (extended car warranties), and this app brings it into ChatGPT. A vehicle service contract picks up after your factory warranty ends and covers major mechanical repairs, so you pay your deductible instead of the full repair bill. Tell Chaiz your car by VIN, license plate, or make, model, and year, plus your mileage and state, and it pulls live quotes from multiple trusted providers so you can compare real prices, coverage, and independent plan ratings side by side. No sales calls, no waiting for a callback, and no handing over your phone number or email just to see a price. When you find a plan you like, Chaiz links you to chaiz.com to read the full contract and check out online.

Chalet-Montagne.com — Mountain holiday rentals
By Alpium
Chalet-Montagne.com is a French mountain holiday rental marketplace, online since 1999, where holidaymakers contact owners directly — no booking commission. This connector gives Claude access to the full catalogue of chalets, apartments and studios rented by their owners in the French Alps, Pyrenees, Jura, Vosges and Massif Central: - search_rentals: free-text destination search (resort, mountain range, ski area) with dates, capacity, budget and amenity filters (sauna, pets allowed, ski-in/ski-out…). - get_rental_details: full listing — description, bedrooms, amenities, rental conditions (check-in/out, deposit, cancellation, pets) and guest reviews. - check_availability_and_price: real-time availability and total stay price, with the closest free periods of the same length when the dates are booked. - prepare_rental_inquiry: prepares a contact request — returns a link to the listing's contact form on www.chalet-montagne.com, pre-filled with the dates, party size and message. Nothing is sent: the user enters their own name, email and phone and submits the form themselves. The owner then replies by email. All four tools are read-only. Every answer links back to the listing page on www.chalet-montagne.com with dates pre-filled. Prices are indicative and confirmed by the owner. No payment and no firm booking ever go through this connector, and owners' personal contact details are never exposed. No account or authentication needed.

By Chamelio
Chamelio is an AI-native intelligence platform for in-house legal teams. The Chamelio connector lets Claude search your contract repository, track and start legal requests, and hand complex questions to Chamelio's AI legal agent. Ask things like "find our MSA with Acme and summarize the key terms", "which NDA requests are still waiting on legal review?" or "start a new NDA request for Anthropic". With Chamelio in Claude you can: • Search contracts by name or structured fields, and read extracted fields, summaries and attributes. • See which tasks are in progress, what step each is waiting on, and who is involved. • Start a new workflow run, such as an NDA request, after confirming the values with you. • Get download links for signed documents from completed workflows. • Delegate multi-contract questions and comparisons to the Chamelio agent. Every tool runs as the signed-in Chamelio user. The connector never approves, signs, edits or deletes contracts. Requires the MCP feature, which your Chamelio admin turns on.

ChampvaDoctors
By ChampvaDoctors
CHAMPVA is the VA health program for the spouses, surviving spouses and children of certain disabled or deceased veterans. It has no provider network: any provider who accepts Medicare assignment can bill CHAMPVA. The hard part is finding one, so families end up calling office after office. ChampvaDoctors lets Claude do that search. Ask for a kind of provider in a US city ("a cardiologist in Dallas", "pediatricians in Tampa") and it returns providers who accept Medicare assignment, with practice name, address, phone number and NPI, plus a link to the full list on ChampvaDoctors.com. The data is ChampvaDoctors.com's own copy of the public CMS Medicare provider file, refreshed monthly. Every answer includes the practical tip families need: a practice can still decline new CHAMPVA patients, so call the billing office first and ask whether they will bill CHAMPVA. Read only. No sign-in. The connector never asks for or stores personal or health information. ChampvaDoctors.com is independent and not affiliated with the VA or CMS.
