At a Glance & Executive Verdict
APIbase
Aggregators · Remote HTTP/SSE
Quality: 63/100 (Good) | Auth: No auth required
Tensorfeed
Aggregators · Local stdio
Quality: 46/100 (Fair) | Auth: other
Verdict Summary: Choose APIbase if you need specialized Aggregators tools running via a hosted cloud SSE transport. Choose Tensorfeed if your workspace requires Aggregators integration with local subprocess execution. Both servers can be configured concurrently in your client's mcpServers manifest.
Which MCP Server Should You Choose?
Choose APIbase when:
You need dedicated capabilities in the Aggregators domain.
You prefer remote streaming HTTP/SSE transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
You have access to required keys: POSTGRES_PASSWORD, X402_PAYMENT_ADDRESS.

Tools & Capabilities Breakdown
APIbase Tools (12)
fetch
HTTP fetch with automatic authentication and payment handling. Makes the request, retries with SIGN-IN-WITH-X when the route exposes a SIWX challenge, and only pays if the route still returns 402. Returns response data and the final response headers, including raw payment receipt proof when supplied by the server, along with payment details (price, tx hash) if a payment was made.
For endpoints you haven't called before in this session, you MUST call check_endpoint_schema first to confirm the request body schema. Skipping this causes 400 errors from wrong field names.
get_balance
Get your total USDC balance across all supported networks. Auto-creates the wallet on first use (~/.agentcash/wallet.json). Use this before paid API calls to confirm you have funds available.
list_accounts
List wallet accounts for each supported network. Returns the network, address, balance, and deposit link for every supported network so you can see where to fund the wallet. Auto-creates the wallet on first use (~/.agentcash/wallet.json). If onboardingCta is present, show its message to the user — it means they haven't onboarded yet and need to either visit the onboard link or deposit directly.
check_endpoint_schema
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
APIbase is categorized under Aggregators and uses a remote streaming HTTP/SSE transport. In contrast, Tensorfeed belongs to Aggregators using local stdio subprocess. Select APIbase when you need capabilities focused on aggregators and Tensorfeed when you require tools for aggregators.
Get the input/output schema and auth mode (paid or SIWX) for a single endpoint.
Call this to see exactly what fields the request body expects and what the response contains.
Returns the schema from the origin's OpenAPI spec. Optionally pass sample_input_body to probe the endpoint live (without payment) for an exact price quote — do this when pricing is dynamic (range-based or variable), or when you're unsure about the input schema. Treat auth mode as advisory: fetch handles both SIWX and paid routes.
redeem_invite
Redeem an invite code for free USDC on Base. One-time use per code. Returns amount received and transaction hash. Use get_balance after to verify funds, or list_accounts if you need the per-network deposit links as well.
discover_api_endpoints
List available endpoints at an API origin. Returns endpoint URLs with descriptions of what each does and the auth mode for each (paid or SIWX). Works with any origin, not just the registered ones.
Call this when you need to see what routes are available at an origin — whether it's one of the registered origins or any other origin you've identified as useful. Treat the auth mode as guidance for what the route may require; fetch handles both SIWX and payment.
The response always indicates whether guidance is available. Guidance is documentation published by the API provider explaining how endpoints work together, edge cases, and usage tips. compact guidance is included automatically; set include_guidance=true to force-include full usage documentation when you need to compose two or more endpoints or need clarification on how the origin works.
report_error
EMERGENCY ONLY. Report critical MCP tool bugs. Do NOT use for normal errors (balance, network, 4xx) — those are recoverable.
update_settings
Update user settings (persisted to ~/.agentcash/settings.json). Currently supports maxAmount — the maximum USD amount allowed per fetch request. If a fetch response requests more than this, the payment is rejected. Returns the current settings after applying changes.
get_settings
Get current user settings. Returns persisted values from ~/.agentcash/settings.json with defaults applied.
bridge
Bridge USDC between supported networks using the current wallet. Requires a source network, destination network, and amount. Use this when funds are on one supported network and the user needs them moved to another. Bridging is subject to fees.
search
Search for relevant paid API services by describing what you need in natural language. Returns the best matching origins with endpoint details and pricing. The top result includes the full input/output schema so you can call it immediately via fetch.
Only use this when you DON'T already know which registered origin to use. If the task clearly maps to a registered origin (e.g. people search → StableEnrich, image generation → StableStudio), skip search and go straight to discover_api_endpoints on that origin. Search is for discovering NEW or UNKNOWN capabilities outside the registered origins.
Set broad=true to widen the search to include newer, unvetted tools that may not have established trust. Use this if the default results don't cover what you need.
sessions_close
Close an MPP `tempo:session` payment channel. Pass the channelId surfaced in a prior fetch's paymentInfo together with the same URL you originally fetched. Signs a close credential with the on-chain settled cumulative amount and POSTs it to the server, returning the on-chain settlement transaction hash when available. Use this when you want to finalize a channel rather than leaving it open for the server to settle on its own schedule.
Tensorfeed Tools (24)
get_ai_news
Get the latest AI news from TensorFeed.ai as a ranked list with title, source, URL, snippet, and publish time, filterable by category (e.g. "anthropic", "openai", "research", "tools"). Aggregates 15+ sources (Anthropic, OpenAI, Google, TechCrunch, The Verge, arXiv, and more) into one normalized feed, so an agent reads one schema instead of polling each outlet. Free, no auth.
find_tensorfeed_data
Discover which TensorFeed endpoint answers a data need. Describe what you want in plain language (e.g. "trending AI papers", "is OpenAI down", "model price history") and this returns the 2 to 3 best-matching TensorFeed endpoints, each with its HTTP path, what it returns, and whether it is free or paid. TensorFeed exposes 100+ AI-ecosystem data and signed-verdict endpoints; the core ones are also dedicated tools, but the full catalog is reachable here and callable over HTTP (paid ones via x402 or a credits token). Free, no auth. Use this first when no dedicated tool obviously fits.
get_ai_status
Get the real-time operational status of major AI services (Claude, OpenAI, Gemini, Mistral, Cohere, Replicate, Hugging Face), including per-component breakdowns and an operational/degraded/down rollup per provider. One cross-provider status call instead of checking each vendor's status page, useful before an agent routes a request to a model that may be impaired. Free, no auth.
is_service_down
Check whether one named AI service (e.g. "claude", "openai", "gemini", "mistral", "cohere", "hugging face", "replicate") is currently operational, degraded, or down, with its component-level breakdown. Matches on service or provider name and lists available services if there is no match, so an agent can gate a call on live status before sending traffic. Free, no auth.
get_model_pricing
Get AI model pricing across major providers (Anthropic, OpenAI, Google, Meta, Mistral, Cohere) in one normalized table: input and output price per 1M tokens, context window, and release date per model. One cross-provider comparison instead of scraping six pricing pages, so an agent can pick the cheapest model that fits its context and budget. Free, no auth.
account_status
Check the configured TensorFeed token: current credit balance plus recent per-endpoint usage (last 100 calls aggregated). Free, but requires TENSORFEED_TOKEN.
route_verdict
TensorFeed's signed model-routing decision: the single best model for a task or named model, fused from live pricing, contamination-discounted benchmarks, real production usage, measured p95 latency, incident state, and deprecation flags, with the reasoning. tier='preview' (default) is free (10 calls per day per IP), top verdict only. tier='full' costs 1 credit ($0.02), adds ranked runners-up, constraint filters, and an AFTA-signed receipt you can audit, and needs a TENSORFEED_TOKEN. Get credits at tensorfeed.ai/developers/agent-payments.
provider_reliability_verdict
TensorFeed's signed dependability ruling over its OWN measured latency and availability probes of the frontier AI providers: the single most-dependable provider to build on and the riskiest, scoring availability and tail consistency (p50 over p95) equally because an agent retry loop feels the tail, not the median. tier='preview' (default) is free (10 calls per day per IP), top verdict only. tier='full' costs 1 credit ($0.02), adds the full per-provider ranking with measured availability and p50/p95/p99 and tail spread plus an AFTA-signed receipt, and needs a TENSORFEED_TOKEN. Get credits at tensorfeed.ai/developers/agent-payments.
x402_settlement_verdict
TensorFeed's signed ruling on the state of the x402 USDC settlement market on Base, computed over its OWN on-chain settlement index: market momentum versus the prior window of equal length, concentration, and the leading publisher. Covers the publishers TensorFeed indexes on Base, forward-only from launch. tier='preview' (default) is free (10 calls per day per IP), headline verdict only. tier='full' costs 1 credit ($0.02), adds the full per-publisher ranking with volume share, ecosystem totals, the Herfindahl concentration index, an optional window, and an AFTA-signed receipt, and needs a TENSORFEED_TOKEN. Get credits at tensorfeed.ai/developers/agent-payments.
x402_publisher_verdict
TensorFeed's signed trust verdict on one x402 publisher, over its OWN on-chain settlement index: whether a named publisher domain is actively settling, recently quiet, registered with no settlement, unreachable, missing a Base payTo, or not indexed. Requires a domain. tier='preview' (default) is free (10 calls per day per IP), the trust verdict only. tier='full' costs 1 credit ($0.02), adds the 30-day settlement momentum, the shared-wallet risk flag, the settlement evidence (volume, count, last settled), and an AFTA-signed receipt, and needs a TENSORFEED_TOKEN. Get credits at tensorfeed.ai/developers/agent-payments.
stack_safety_verdict
TensorFeed's deploy gate for an AI software stack: pass each package as comma-separated name@version and get the overall BLOCK / HOLD / PASS / UNKNOWN gate plus a per-package verdict, fusing the ingested AI-stack CVE batch with the CISA KEV catalog. Conservative by design: BLOCK only on an exploited CVE with no fix, HOLD when a known CVE applies and you must verify your version, PASS on no match, UNKNOWN outside the curated AI-stack cohort. tier='preview' (default) is free (10 calls per day per IP), caps at 3 packages, gate plus worst offender. tier='full' costs 1 credit ($0.02), raises the cap to 10 packages, adds the matched-CVE evidence (ids, affected ranges, fixed versions, KEV status) and an AFTA-signed receipt, and needs a TENSORFEED_TOKEN. Get credits at tensorfeed.ai/developers/agent-payments.
benchmark_trust_verdict
TensorFeed's signed ruling on whether an AI benchmark is still a trustworthy capability signal or saturated, contaminated, or near ceiling so a high score should be down-weighted: a trust band (reliable, use_with_caution, saturated, contaminated, deprecated) and a 0-100 trust score per benchmark. Pass benchmark to narrow to one, or category to filter, or neither for the registry. tier='preview' (default) is free (10 calls per day per IP), top verdict and bands only. tier='full' costs 1 credit ($0.02), adds the per-signal detail (ceiling proximity, frontier compression, contamination), a down-weight recommendation with an alternative benchmark, and an AFTA-signed receipt, and needs a TENSORFEED_TOKEN. Get credits at tensorfeed.ai/developers/agent-payments.
