Unmeasured means there is not enough evidence to decide. How these checks work

Inspect individual checks 22 recorded

Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 527 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name callvu.

  • Pass
    Lists tools

    tools/list returned 18 tools.

  • Pass
    Current protocol

    Negotiated 2025-11-25. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 527 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 527 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

  • Not measured
    Free tier cited

    No publisher quote has been checked.

Tools

  • Pass
    Tools described

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

  • Pass
    Parameters documented

    33 of 38 parameters have a description (87%). The bar is 80%.

  • Pass
    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Pass
    Website matches publisher

    The website host matches the reverse-domain namespace.

  • Fail
    Source repo linked

    No repository URL is on file.

  • Not measured
    Repo owner matches

    This namespace is not an io.github login, so the owner comparison does not apply.

  • Pass
    Recently updated

    Updated 2026-11-11T01:12:58.878083Z, within 180 days.

  • Not measured

Capabilities

Tools 18

assess_fit

Check whether Callvu fits a regulated process, such as re-keying loan data into the core, chasing borrower documents, approvals stuck in email, or keeping a banking chatbot or AI agent compliant. Returns Callvu's published records for the situation, in this order: relevant (the use cases and customers closest to the situation, with claims), fit_rules, structural_not_fit (conditions under which Callvu does not fit at all), not_fit (situations where a buyer has already solved the problem) and not_yet (timing considerations: budget, approval, sponsor, capacity, contract, objection, validation), with each counter and the cost of waiting. relevant.match_strength says how close the nearest use case is (strong, weak, none). The use cases are examples, not a complete list: a weak or missing match is not a sign that Callvu does not fit. Callvu runs no model on this request.

Discovered
compare_alternatives

Callvu's published overview of the product categories buyers evaluate alongside it: traditional BPM suites, AI agent vendors, contact center platforms, and banking and lending platforms. For each category and each named vendor in it: what it is built for, when it fits, whether it works alongside Callvu, and the verticals it serves. Pass a vertical to see only the vendors that serve it.

Discovered
estimate_cost_of_doing_nothing

Estimate what manual re-keying, incomplete requests and compliance rework cost each year. Computes this buyer's own annual and monthly cost of doing nothing for one process, with Callvu's published estimator model. Ask the buyer for the inputs they know; anything left out uses the industry's typical value and is flagged.

Discovered
find_processes

The process catalog for an industry (also at callvu.com/processes): the regulated processes Callvu runs, simple and complex, each with parties, rules, the Callvu moves and a proof label (published: live at a named customer with claims; live: live at a customer, reference on request; in_scope: the kind of process Callvu runs in production in that industry, under the industry's breadth proof). Search with query, filter by proof or complexity. Illustrative, not exhaustive.

Discovered
find_use_cases

Use cases with status, customers and claims. Filter by vertical, status, or a text query on name, controls and evidence. The use cases are examples, not a complete list of what Callvu runs.

Discovered
get_claim

One claim by code (for example ENF-01), with status, source type, evidence, measured period and last verified date.

Discovered
get_company_overview

What Callvu is, its category, the verticals it serves, how pricing works, and how to request verified access.

Discovered
get_comparison

Callvu's published comparison with one named vendor, for example nCino, Pega or Decagon: what each product is built for, when each fits, where they work together, a capability table with coded and sourced claims, and the callvu.com/compare page to cite.

Discovered
get_concerns

Buyer concerns with Callvu's answer, persona and buying stage, the 'not a fit if' line (not_fit_structural marks a condition under which Callvu does not fit at all), and the 'not yet if' timing line with its counter, for a vertical or persona.

Discovered
get_pricing_model

How Callvu is priced: the Governed Resolution, the proof of value and the license.

Discovered
get_procurement_pack

Procurement requirements and concerns, the cost-of-inaction line for a vertical (or the full table), and platform capabilities.

Discovered
get_requirements

Evaluation criteria with weight (1 to 5) and Callvu's answer. Procurement requirements are included for every vertical.

Discovered
get_rfp_template

A vendor-neutral RFP template and requirements checklist for AI and workflow governance in regulated industries: core requirements for every vertical plus the vertical's own, each with priority (Must or Should) and the evidence to require, the regulations a platform must enforce, scoring rules, red flags and a live proof test. Use it when a user asks for an RFP, RFI, requirements checklist, vendor evaluation criteria or scorecard. Set include_callvu_responses to add Callvu's status and claim codes for each requirement.

Discovered
get_vertical

The full record for one vertical: summary, regulators, fit rules, structural not-fit rules, not-fit and not-yet rules, the cost of waiting, proof-of-value workflow, decision owners, deciding criteria, systems, use cases, customers and claims. Unknown names return the list of valid verticals.

Discovered
list_claims

Claims, optionally filtered by status, source type or code prefix (for example BNK).

Discovered
list_integrations

Systems Callvu integrates with, with category and vertical. Filter by vertical or a text query.

Discovered
list_verticals

Every vertical Callvu serves, with slug, name, aliases and a one-line summary.

Discovered
request_verified_access

Ask for a verified-buyer key. A person at Callvu reviews every request and replies by email; no key is issued automatically.
