Best for	Operate IBM Quantum Runtime jobs and inspect quantum hardware from MCP clients Operate IBM Quantum Runtime jobs and inspect quantum hardware from MCP clients.	Current library and API documentation inside coding agents Read-only technical lookup with a small two-tool surface Users who want remote or local npx connection options
Not ideal for	Submitting Sampler/Estimator jobs can consume limited quantum resources or paid plan capacity. Job cancellation and deletion of saved account credentials are consequential actions and should require explicit human confirmation.	Private internal documentation not indexed by Context7 Guaranteed authoritative answers without checking the cited upstream docs Offline-only development

Client coverage note	Local stdio runs on your computer. Streamable HTTP connects to a remotely hosted MCP server.
Access and data
Authentication	IBM Quantum API token or previously saved Qiskit IBM Runtime credentials.	Remote MCP accepts CONTEXT7_API_KEY as an HTTP header. The local package accepts --api-key. The CLI can use OAuth to generate an API key; unauthenticated documentation commands may have lower limits.
Cost	Submitting Runtime jobs can consume IBM Quantum plan, quota, or paid capacity depending on the account.	A free API key and free usage are documented, with higher-rate or team/enterprise offerings potentially requiring a paid plan. Applicable limits should be checked in the current Context7 dashboard.
Permissions	Operations run under the authenticated IBM Quantum account/instance and its available backend/job permissions.	The MCP surface resolves library identifiers and queries documentation. It does not require repository or filesystem write access for the documented hosted mode.
Data handling	Circuit/job requests and results are sent to and retrieved from IBM Quantum Runtime services.	Context7 states that formulated queries are sent to its API while full prompts, source code, and conversation history are not transmitted; its tool descriptions instruct clients to remove secrets, personal data, and proprietary code.
Limitations
Tradeoffs	Shortlist evidence is sufficient for identity, setup and task value; authenticated runtime tool-schema measurement and exhaustive security certification remain out of scope.	An API key is recommended for higher limits, adding account and secret management. Context7 says it sends formulated queries rather than full prompts or source code, but queries still leave the client. Community-contributed projects can be incomplete or inaccurate and should be checked against primary documentation.
Risk context	The MCP can submit Estimator/Sampler jobs, consume scarce or paid quantum resources, cancel jobs, and delete locally saved account credentials.	Primary risks are query disclosure, stale or inaccurate indexed documentation, and accidental API-key exposure. Keep queries free of proprietary details and verify consequential advice against first-party library documentation.
